Omega-3 supplementation. Answers to frequently asked questions. post image

There are many myths circulating in the media about omega-3 supplementation. It’s time to dispel them all. Read our answers to the most frequently asked questions and find out exactly what, how and when.

What exactly are omega-3 fatty acids, and what roles do they play in our bodies?

Omega-3 fatty acids are polyunsaturated fatty acids that the body cannot produce in sufficient quantities, so they must be obtained from the diet. The most biologically important forms are EPA and DHA. They perform many structural and regulatory functions in the body.

The key areas where omega-3 is effective:

Omega-3 fatty
acids are a component of the phospholipids that make up cell membranes. They influence membrane fluidity, intercellular communication and the proper functioning of receptors.

The brain and nervous system
: DHA is an important structural component of the brain and the retina. It supports healthy cognitive function and the development of the nervous system, particularly during pregnancy and childhood.

Gut
microbiota Research suggests that omega-3s may help maintain the balance of the gut microbiota and the integrity of the intestinal barrier, thereby complementing the effects of probiotics.

Cardiovascular system
: EPA and DHA support healthy heart function and help maintain healthy triglyceride levels when consumed in adequate amounts.

The immune system and inflammatory balance
Omega-3 fatty acids are precursors of compounds involved in suppressing inflammatory responses and maintaining immune balance.

The skin and the hydrolipid barrier: These
factors influence the condition of the skin, support the skin barrier and may affect the composition of sebum by regulating inflammatory mediators.

Prenatal
DHA plays an important role in the development of the brain and vision in foetuses and infants.

In practice, omega-3s have a systemic effect, as they play a role in fundamental biological processes at the cellular level.

Why is it important to take omega-3 supplements derived from fish or microalgae?

The most biologically significant forms of omega-3 fatty acids are EPA and DHA, which are found mainly in oily sea fish and microalgae. It is these long-chain fatty acids that are directly utilised by the body to build cell membranes, regulate inflammatory processes and support brain, heart and eye function.

Although plant-based products such as linseed oil and chia seeds contain ALA (a plant-based form of omega-3), the body’s ability to convert it into EPA and DHA is very limited. For this reason, direct sources of EPA and DHA — derived from fish or microalgae — are considered the most effective for daily supplementation.

Supplementation may be particularly important in the context of the modern diet. Most European adults, including Poles, do not meet the recommended intake of approximately 250 mg of EPA and DHA per day, mainly due to low consumption of oily sea fish. Population studies also indicate low levels of the so-called Omega-3 Index in Central European countries, suggesting a widespread deficiency of these fatty acids.

Fish oil or microalgae supplements provide EPA and DHA in a ready-to-use, biologically active form, making them a practical dietary supplement — both for people who eat little fish and for those on plant-based diets who choose omega-3 from algae.

Which omega-3 supplements are suitable for vegans?

For those on a plant-based diet, there are omega-3 supplements made from microalgae, which naturally contain DHA and EPA. This is a healthy and ethical alternative to fish oil.

How do omega-3 supplements differ from one another?

Not all omega-3 supplements are the same. They differ in terms of their chemical form, purity and degree of oxidation, EPA and DHA content, source, and form (capsules, liquid oil, gummies, etc.). All of these factors also affect their price.

What should you look out for when making a purchase?

Choosing the right omega-3 supplement is crucial to its quality and effectiveness. It is worth paying attention to a few key factors:

EPA and DHA content in a daily serving
What matters most is the actual amount of EPA and DHA, not the amount of fish oil itself. It is these two fatty acids that are responsible for most of the health benefits.

Independent quality certificates
Certificates such as IFOS or other laboratory testing schemes confirm the purity of the product, the accuracy of its composition as declared, and low levels of environmental contaminants.

Low oxidation levels (TOTOX index)
Omega-3s are sensitive to oxidation, so it is advisable to choose products with a low TOTOX index, which indicates the oil’s freshness and stability.

Source of raw material and purification process The origin of the oil (e.g.
wild marine fish or microalgae) is important, as are the purification methods used, which help to remove heavy metals and other contaminants.

Chemical form and bioavailability
Omega-3s can be found, for example, in the form of triglycerides or ethyl esters. The triglyceride form is the closest to the natural structure of the fats found in fish. It is well tolerated by the digestive system and is highly stable.

A supplement form tailored to individual needs:
Capsules are convenient to take, whilst liquid oil often allows for a higher daily dose of EPA and DHA. It is also often the only form acceptable to people who have difficulty swallowing capsules. It is therefore important for the manufacturer to offer a range of supplement forms.

Making an informed choice when selecting an omega-3 supplement allows you to tailor it more effectively to your individual needs and lifestyle.

What independent quality certifications might omega-3 supplements have?

IFOS – International Fish Oil Standards

This is one of the best-known independent fish oil testing schemes. IFOS certification means that the product has been assessed for:

  • contaminants (heavy metals, dioxins, PCBs),
  • compliance of the EPA and DHA content with the declaration,
  • oxidation level (oil freshness),
  • safety and quality.

This programme is regarded as one of the most rigorous standards for the assessment of fish oil in the world.

FOS – Friend of the Sea

This certification focuses primarily on the sustainable sourcing of raw materials and the protection of the marine environment. Among other things, it means:

  • sustainable fishing,
  • minimal impact on the ecosystem,
  • monitoring of raw material sources.

This is an important factor for people who care not only about product quality but also about its environmental impact.

MSC – Marine Stewardship Council

The MSC certificate confirms that the fish used to produce the oil come from sustainably managed fisheries.

This mainly concerns environmental aspects:

  • the protection of fish stocks,
  • responsible management of ocean resources.

GOED – Global Organisation for EPA and DHA Omega-3

GOED is an international trade association representing omega-3 producers. Membership entails, amongst other things:

  • adherence to high quality standards,
  • checking the purity of raw materials,
  • transparency in production.

Regular laboratory tests confirm the absence of contaminants and the high stability of the omega-3 oil.

When is the best time to take omega-3 – in the morning or in the evening?

The most important thing is to take them with a meal containing fat, as this improves absorption. The time of day is less important than taking them regularly.

Do omega-3s cause ‘fishy burps’?

This can happen if you use low-quality oils or take them on an empty stomach. Choosing a fresh product with a low TOTOX rating and taking it with food can help.

How long should you take omega-3 supplements?

Omega-3s are a dietary component, so they can be taken over the long term — particularly when intake of oily fish is low.

How should omega-3 supplements be stored to ensure they retain their properties?

Omega-3 fatty acids are sensitive to light, temperature and oxygen, which is why proper storage is crucial to their quality.

🧴 Liquid omega-3 oils

Before opening:
• store in a cool, shaded place,
• avoid high temperatures and direct sunlight.

Once opened:
• store in the fridge,
• always close the bottle tightly,
• use within the time recommended by the manufacturer.

Low temperatures slow down fat oxidation and help preserve freshness.

💊 Omega-3 capsules

Before and after opening:
• store at room temperature in a dry place,
• protect from light and moisture,
• if the ambient temperature exceeds 25 degrees, it is best to move the product to the fridge or another cooler place.

If the capsules develop a strong fishy or bitter smell, this may indicate that the oil has gone rancid.

Can omega-3 be taken alongside vitamins D and K2?

Yes — many people take them together as part of a single meal. As these ingredients are fatty in nature, they are best absorbed under similar conditions.

What is the TOTOX index?

TOTOX measures the degree of fat oxidation. A lower value indicates that the oil is fresher and that the omega-3 fatty acids are more stable. For example, the dietary supplement Norsan Arktis has a TOTOX value of 1.5, which is an excellent result and attests to the product’s superior quality.

I’m not sure if I need to take supplements. How can I find out?

Omega-3 levels in the body can be assessed using specialist laboratory tests that analyse the fatty acid profile in the blood. One example is the Omega Test, which determines the composition of lipids and the proportions of fatty acids in the body.

The test involves analysing the fatty acid composition of a blood sample. The laboratory uses advanced analytical techniques, such as gas chromatography, to accurately determine the levels of various types of lipids, including EPA and DHA.

The results of the study show, among other things:

  • omega-3 levels,
  • omega-3 to omega-6 ratio,
  • trans fat index,
  • additional markers of inflammation, e.g. the AA/EPA ratio.

The results are interpreted in the context of lifestyle, diet and health goals. This analysis enables a more personalised approach to diet and supplementation, particularly for those at risk of cardiovascular or metabolic diseases.

We invite you to read our series of articles on the microbiota and prebiotics (Part 6)

This section is intended for dietitians, doctors, pharmacists and specialists who want to understand the mechanisms behind the science, rather than just marketing slogans.

Formulation principles – what functions of the microbiota does MegaPresupport?

A modern selective prebiotic (such as MegaPre) should target key groups of bacteria associated with:

  • the production of butyrate (Faecalibacterium prausnitzii),
  • the integrity of the intestinal barrier (e.g. Akkermansia muciniphila),
  • classic ‘good’ bacteria (Bifidobacterium spp., Lactobacillus spp.).

The benefits of MegaPre from a specialist’s perspective:

  • increased production of SCFAs (particularly butyrate),
  • improving the integrity of the intestinal barrier (promoting the synthesis of mucins, claudins and occludins),
  • a reduction in ‘leaky gut’ and low-grade chronic inflammation,
  • modulation of the immune response (increase in Treg cells, regulation of Th1/Th2),
  • support for glucose and lipid metabolism,
  • restoration of key microbiota functions following antibiotic treatment.

Mechanisms of action – microbiological, immunological and metabolic levels

At the level of the microbiota:

  • stimulation of SCFA production,
  • increasing microbial diversity,
  • reduction of opportunistic bacteria through changes to the environment (pH, SCFAs).

At the level of the intestinal barrier:

  • feeding colonocytes with butyrate,
  • increased expression of tight junction proteins,
  • increased mucin production and regeneration of the mucous membrane.

At the level of the immune system:

  • Treg stimulation (regulation of immune tolerance),
  • modulation of the Th2 response (important in allergies and atopic dermatitis),
  • an overall reduction in chronic, low-grade inflammation.

At the metabolic level:

  • the effect of SCFAs on GPR41/43 receptors,
  • improved insulin sensitivity,
  • an indirect effect on lipid profile and body weight (depending on the clinical context).

FAQ for professionals – MegaPre™ in the clinic

Which groups of bacteria does MegaPre™ work best on, and what is the evidence?

MegaPre™ supports butyrate-producing bacteria (Faecalibacterium, Roseburia, Eubacterium), barrier-forming bacteria (Akkermansia) and Bifidobacterium. Data from studies on the prebiotic fractions used in MegaPre indicate an improvement in microbial diversity and an increase in anti-inflammatory metabolites (SCFAs).

Can MegaPre be used in patients with IBS, IBD or following a course of antibiotics?

Yes – subject to the protocol being amended:

  • IBS (particularly IBS-C): careful, gradual dose escalation,
  • IBD: only in remission, with a particular focus on butyrate production,
  • during and after a course of antibiotics: to support the restoration of the gut microbiota (with a probiotic).

How should the effects of MegaPre™ be assessed in a patient?

In patients, the effects of MegaPre™ can be assessed in two ways: symptomatically and functionally.

Symptomatically:

  • the Bristol Stool Chart,
  • symptom diary (bloating, pain, feeling of fullness),
  • frequency of bowel movements,
  • a subjective feeling of ‘lightness in the stomach’.

Functionally (where available):

  • CRP, sometimes calprotectin,
  • fasting blood glucose, HOMA-IR, lipid profile,
  • microbiome studies (contribution of butyrate-producing bacteria, Bifidobacterium, etc.)

Is MegaPre™ suitable for patients on a low-FODMAP diet?

During the elimination phase – usually not. During the reintroduction phase – yes, but in gradually increasing doses. The low-FODMAP diet is intended as a short-term measure; long-term avoidance of FODMAPs may impair the quality of the gut microbiota. MegaPre can help restore gut flora and increase tolerance to FODMAPs if introduced carefully.

How does MegaPre affect SCFA production, and why is this clinically significant?

 MegaPre supports bacteria that produce SCFAs – particularly butyrate, propionate and acetate. This results in:

  • the regeneration and nourishment of colonocytes,
  • improved intestinal barrier integrity,
  • reduction of low-grade inflammation,
  • support for the immune response (increase in Treg cells),
  • modulation of glucose and lipid metabolism.

In clinical practice, this means, amongst other things, a reduction in bloating and discomfort, better dietary tolerance, a more regular bowel movement pattern, improved immunity, and support for patients with IBS, IBD in remission, insulin resistance and metabolic disorders.

Frequently Asked Questions (FAQ)

Are probiotics and prebiotics the same thing?

No – they are two different things that perform different functions in the gut. A probiotic is a live bacterium (or yeast) with documented health benefits. A prebiotic is an indigestible dietary component that acts as food for specific ‘good’ bacteria. In short: a probiotic supplies microorganisms, whilst a prebiotic ‘feeds’ them and supports their growth.

You could compare it to sowing seeds in a garden: a probiotic is like new seeds, whilst a prebiotic is like fertiliser and good soil. Without soil and fertiliser, even the best seeds won’t grow as well as they could.

Key points:

  • probiotic = live bacteria
  • prebiotic = food for specific bacteria
  • They work best together, but each one also has its own merit.

Can I take prebiotics on their own, without probiotics?

Yes, in many cases, a prebiotic on its own can be very effective. For people who do not have serious microbiota imbalances but, for example, eat few vegetables and struggle with constipation, bloating or mild intestinal discomfort, a well-chosen prebiotic acts as a ‘daily fertiliser’ for the gut flora. It supports the bacteria that are already there, rather than adding new ones.

A prebiotic can be particularly helpful when the aim is to:

  • control of bowel movements,
  • improved gut health,
  • support for the intestinal barrier and SCFA production,
  • long-term gut health maintenance.

In more complex situations (e.g. following a course of antibiotics, in IBS, or inflammatory bowel disease), combining a prebiotic with a probiotic – a synbiotic – will usually be a more effective and better-documented approach.

When will I see the effects of the probiotic or prebiotic?

It depends on the desired effect. In acute cases – such as post-antibiotic diarrhoea – a suitably chosen probiotic (e.g. RestorFlora PD™) can take effect within a few dozen hours. For more complex goals, such as boosting immunity, regulating the microbiota or improving metabolism, we’re talking about weeks or even months of regular use.

Indicative timeframe:

  • severe diarrhoea – often improves within 1–3 days,
  • regulation of bowel movements, constipation – 5–14 days,
  • improvement in bowel comfort and bloating – 2–4 weeks,
  • immune support – usually 4–12 weeks,
  • effect on metabolic parameters – usually at least 8–12 weeks.

The microbiota doesn’t ‘flip’ like a switch – it’s more like a garden that needs to be watered, fertilised and given time to grow.

Is all fibre a prebiotic?

No. Fibre as such has numerous benefits (including increasing stool bulk, improving peristalsis and slowing down glucose absorption), but only certain types of fibre meet the criteria for a prebiotic. A prebiotic must be indigestible, fermented by the microbiota, and selectively promote the growth of specific beneficial bacteria.

In practice, this means that:

  • Every prebiotic is a type of fibre,
  • but not all fibre deserves to be called a prebiotic.

We discussed prebiotics in more detail in the first part of our series on the microbiota and prebiotics:

https://novolabs.pl/artykul/dlaczego-mikrobiota-jelitowa-ma-takie-znaczenie/

The best-known prebiotics include inulin, FOS, GOS, resistant starch and arabinogalactan – these are ingredients found in more advanced prebiotic formulas, such as MegaPre™.

Will the gut microbiota recover on its own after a course of antibiotics?

Not entirely. The microbiota does have some ability to regenerate, but this happens slowly and does not always return to its ‘original state’. Following antibiotic treatment, some bacteria disappear, the diversity of the microbiota decreases, and it becomes easier for opportunistic and pathogenic species to overgrow. Research suggests that a spontaneous return to relative balance can take months, and sometimes years.

Inclusion of a prebiotic and a probiotic:

  • speeds up the restoration of balance,
  • reduces the risk of post-antibiotic diarrhoea,
  • supports the renewed production of SCFAs,
  • helps to restore the intestinal barrier,
  • prevents overgrowth of Candida or C. difficile.

That is why, after taking antibiotics, it is worth thinking not only about ‘how to get through the course of treatment’, but also about ‘how to restore the gut microbiota after treatment’.

Is it possible to take too many probiotics?

Yes, although it’s very difficult. Probiotics are a bit like vitamin supplements – in theory they’re ‘good’, but in excess or at the wrong time they can do more harm than good. Too high a dose, the wrong strain, or taking probiotics when the gut is severely disrupted can lead to increased bloating, constipation, overflow, abdominal pain or a feeling of a “bloated stomach”.

In most healthy people, an excess of probiotics will mainly result in discomfort. However, in people who are severely immunosuppressed, who have undergone transplants, who have advanced cancer, or who have damage to the intestinal barrier, probiotics should only be taken after consulting a doctor.

Reasonable rules:

  • select strains for the indication,
  • do not keep increasing the doses indefinitely ‘just in case’,
  • monitor your body's reactions,
  • for people with chronic conditions – the decision lies with the doctor, not the internet.

Is there any point in taking prebiotics or probiotics whilst on hormonal contraception?

Definitely yes. Hormonal contraception can indirectly affect the gut and vaginal microbiota – for example, through changes in hormone levels and the immune response. Some women experience recurrent vaginal infections, bloating, constipation or mood swings during this time.

Prebiotics and probiotics do not ‘neutralise’ the effects of the contraceptive pill, but they can help the body cope with the side effects of lifestyle factors and hormonal changes:

  • help maintain a healthy gut microbiota,
  • indirectly support the gut-brain axis,
  • help to stabilise the intestinal and immune barriers,
  • Some strains, even when taken orally, can modulate the vaginal microbiota by increasing lactic acid production and optimising pH (e.g. those contained in Vaginal Balance™), which helps to reduce vaginal dryness, boost resistance to infections and improve women’s quality of life.

This isn’t a cure for the side effects of contraception, but rather part of maintaining the body’s balance, particularly if you experience digestive symptoms, recurrent genital infections or a weakened immune system.

Do prebiotics and probiotics help with weight management?

Yes and no. There is no scientifically valid ‘weight-loss probiotic’. However, studies do show that the composition of the microbiota differs in overweight and obese individuals compared to those of normal weight, and that modulating the microbiota may support metabolism. In recent years, researchers have been paying particular attention to the bacterium Akkermansia muciniphila. Clinical and metagenomic studies consistently show that low levels of A. muciniphila correlate with:

  • obesity and insulin resistance,
  • type 2 diabetes,
  • non-alcoholic fatty liver disease (NAFLD),
  • low-grade inflammation (‘metabolic endotoxemia’).

In obese individuals, levels of A. muciniphila can be as much as 3–5 times lower than in lean individuals.

Prebiotics and probiotics can:

  • improve insulin sensitivity,
  • influence satiety via SCFAs and gut hormones,
  • reduce low-grade inflammation, lower levels of metabolic endotoxemia,
  • help regulate blood sugar levels,
  • increase the intestinal population of A. mucinophila (particularly prebiotics from the xylo-oligosaccharide (XOS) group)

This means they can be an important part of a weight-loss strategy – but always as a complement to diet, exercise, sleep and stress management, rather than a magic substitute for these elements.

Is there any point in taking prebiotics or probiotics if you have coeliac disease?

Yes. In coeliac disease, the cornerstone of treatment is a strict gluten-free diet – there are no shortcuts here. At the same time, it is known that in many people with coeliac disease, the gut microbiota is disrupted, and the intestines have been exposed to inflammation and damage to the villi for a long time.

Prebiotics and probiotics can play a supportive role here:

  • improve gut health,
  • support the regeneration of the epithelium and the intestinal barrier,
  • reduce inflammation,
  • promote regular bowel movements,
  • to aid digestion and the absorption of certain nutrients as the intestines begin to heal.

In addition to prebiotics and probiotics, plant polyphenols and amino acids such as glutamine, proline, serine, threonine and cysteine (contained in the MegaMucosa™ supplement) also help to support the regeneration of the intestinal barrier.A prerequisite: a gluten-free diet first; only on this foundation is it worth building support for the microbiota.

Is there any point in taking prebiotics or probiotics for Crohn’s disease?

Yes, but. In Crohn’s disease, the role of the microbiota is very significant, but this is an area requiring particular caution. It is a chronic, inflammatory condition characterised by periods of flare-ups and remission. Prebiotics and probiotics can provide some support, but they are no substitute for treatment administered by a gastroenterologist.

During remission, carefully selected prebiotics can:

  • support butter producers,
  • support the intestinal barrier,
  • help maintain a more stable microbiota,
  • reduce inflammation.

There is research suggesting that certain probiotics may be beneficial for IBD, but their selection and dosage should be determined on a case-by-case basis. During a flare-up, the intestines are highly sensitive – in such cases, the treating doctor always takes the lead.

Are prebiotics safe for people with SIBO?

Yes, but. This is one of the trickiest questions. SIBO (small intestinal bacterial overgrowth) is a condition where there are too many bacteria in a place where there should normally be very few. If, at this stage, we ‘add fuel to the fire’ by taking a prebiotic, the symptoms may worsen: more gas, pain and bloating.

In a healthy digestive system, prebiotics reach the large intestine and ferment there, exactly where they should.

In SIBO, some bacteria migrate to the small intestine → fermentation begins too early, leading to:

  • bloating,
  • bouncing,
  • “gurgling” and pain in the upper abdomen.

This is precisely why people with SIBO react more strongly even to small amounts of fibre.

This does not mean that prebiotics are ‘bad’ – it simply means that their type, quantity and timing of introduction play a very important role here. Usually, one does not start with classic “bifidogenic” prebiotics (inulin, FOS, GOS), as these are short-chain, easily fermentable oligosaccharides (high in FODMAPs) which may exacerbate symptoms.

For people with SIBO, it is recommended to take prebiotics containing low-viscosity, slowly fermentable fibre that acts mainly in the large intestine, such as: 

  • partially hydrolysed guar gum (PHGG),
  • acacia fibre (gum arabic), 
  • arabino-galactans,
  • arabinose-glucosides.

If someone has SIBO and feels worse after taking a prebiotic, it’s not ‘their fault’ – it’s a sign that their gut needs a different approach.

Is bloating after taking a prebiotic normal?

Yes, to a certain extent, this is a normal part of the adaptation process. Prebiotics are fermented by bacteria in the large intestine, and fermentation produces gas and short-chain fatty acids (SCFAs). In people with a very ‘hungry’ gut microbiota, the gut may react quite strongly.

Most commonly, bloating and flatulence:

  • appear in the first few days,
  • gradually fade as they adapt,
  • subside after 5–7 days or following a slight reduction in the dose.

Good practice:

  • start with half the dose,
  • increase gradually,
  • stay hydrated (essential) and keep active,
  • Do not stop taking the supplement after a single ‘bad’ day if the symptoms are mild.

Why does combining a prebiotic and a probiotic (a synbiotic) produce the best results?

Synbiotics combine the best of both worlds: live, beneficial microorganisms and precisely selected ‘fuel’ for them. This approach is increasingly replacing the ‘probiotics alone’ strategy.

In the synbiotic:

  • a probiotic supplies new bacteria,
  • prebiotic:
    • increases their survival rate,
    • helps them colonise the gut,
    • stimulates their metabolic activity.

Review studies (Markowiak and Śliżewska, 2017) suggest that synbiotics:

  • may be more effective than a probiotic or prebiotic on its own,
  • run faster and more reliably,
  • are more effective in treating intestinal disorders and preventing diarrhoea.

Benefits of using a synbiotic:

  • faster and more stable recovery of the microbiota following antibiotic treatment,
  • increased production of SCFAs,
  • a better effect on stool consistency and regularity,
  • a potentially lower risk of recurrence of intestinal symptoms,
  • greater predictability of the effect than with a probiotic alone.

 👉 If the aim is to actively influence the microbiota (e.g. following a course of antibiotics, in cases of IBS or inflammatory bowel disease), a synbiotic usually makes more sense than a probiotic on its own.

Who are prebiotics and probiotics for?

Prebiotics and probiotics can be seen as part of a healthy lifestyle, but there are certain groups for whom their use is particularly beneficial. Dysbiosis – an imbalance in the gut microbiota – is now a very common consequence of modern lifestyles (diet, stress, lack of sleep, medication).

Situations in which prebiotics, probiotics or synbiotics should be considered:

  • following antibiotic treatment (prevention and treatment of diarrhoea, restoration of the gut microbiota),
  • for constipation, bloating, IBS, irregular bowel movements,
  • with a diet low in fibre and vegetables,
  • in people living with chronic stress or sleep disorders,
  • if you are prone to infections (weakened immune system),
  • in children with infectious and post-antibiotic diarrhoea (selected strains),
  • in older people – for constipation and motility disorders,
  • in autoimmune diseases,
  • in certain inflammatory and metabolic conditions (always as a complementary measure, not a substitute for treatment).

People who have undergone antibiotic treatment

Antibiotics do not distinguish between ‘good’ and ‘bad’ bacteria. Many people experience diarrhoea, bloating and discomfort after a course of treatment. Probiotics help to restore the gut microbiota, whilst prebiotics feed the strains we wish to support. A synbiotic combination is particularly beneficial in this context.

People with dysbiosis and its consequences

Constipation, bloating, IBS and IBD, and irregular bowel movements – these are typical conditions in which modifying the gut microbiota can improve quality of life. Prebiotics regulate bowel movements and stool consistency, whilst probiotics can alleviate pain and discomfort.

If you have IBS or other conditions or illnesses, it is advisable to consult a specialist before choosing a prebiotic, as not all types of fibre will be beneficial in this case.

People with a weakened immune system (use with caution)

The microbiota is closely linked to the immune system. For people who are frequently ill or under a great deal of stress, supporting gut health can lead to a reduced susceptibility to infections. However, for those with severe immunosuppression, the choice of probiotics should always be made in consultation with a doctor.

Children and senior citizens

  • In children, certain probiotics have a well-documented effect in preventing infectious and post-antibiotic diarrhoea,
  • In older adults, prebiotics support bowel motility and the absorption of minerals, whilst probiotics help to stabilise the gut microbiota and boost immunity.

Restrictions and safety

Although prebiotics and probiotics are generally well tolerated, they are not ‘as harmless as water’. They require careful introduction and a personalised approach.

The most common side effects, which are usually mild:

  • bloating,
  • gases,
  • a rumbling in the stomach,
  • slight changes in bowel habits at the start of supplementation.

When to be particularly careful:

  • active, severe inflammatory bowel disease,
  • post-operative conditions affecting the gastrointestinal tract,
  • immunosuppression (e.g. following transplants, during intensive cancer treatment),
  • SIBO – in this group, certain prebiotics and probiotics may exacerbate symptoms (they require a cautious, protocol-based approach and specific types of prebiotics).

How do probiotics work?

Probiotics perform many functions simultaneously – some of these are felt by the patient almost immediately (e.g. relief from diarrhoea), whilst others work more subtly, regulating the immune system and metabolism. Recent research shows that probiotics:

  • affect the composition of the microbiota,
  • communicate with immune cells and the intestinal epithelium,
  • modulate the inflammatory response and the intestinal barrier.

The main mechanisms of action of probiotics:

  • Competition with pathogens
    • occupy sites of adhesion on the intestinal epithelium,
    • use up the available nutrients,
    • produce substances with antibacterial properties.
    • increased mucus production,
    • effect on tight junction proteins (claudins, occludin),
    • a reduction in the permeability of the intestinal barrier.
    : Strengthening the intestinal barrier
    • activation and regulation of dendritic cells,
    • effect on the Th1/Th2/Treg balance,
    • reduction of chronic inflammation.
    : Modulation of the immune system

How do prebiotics work?

To understand how prebiotics work, we need to view the gut as a living ecosystem. For bacteria to grow, they need the right nutrients. Prebiotics act as a targeted fertiliser – they support only the strains we want to cultivate and help them multiply rapidly.

Unlike probiotics, which we add like building blocks, prebiotics strengthen the foundations of the entire microbial ecosystem.

The main effects of prebiotics:

  • selective stimulation of ‘good’ bacteria (e.g. Bifidobacterium, Lactobacillus),
  • increased production of SCFAs (including butyrate),
  • strengthening the intestinal barrier (tighter connections between cells),
  • regulation of bowel motility (including relief from constipation),
  • modulation of the immune system (reduced susceptibility to chronic inflammation),
  • metabolic effects (blood glucose levels, lipid profile, insulin resistance).

What the research shows:

  • FOS, GOS and inulin increase the abundance of Bifidobacterium and Lactobacillus (Gibson GR, Roberfroid MB. Dietary modulation of the human colonic microbiota: introducing the concept of prebiotics. J Nutr. 1995 Jun;125(6):1401-12. doi: 10.1093/jn/125.6.1401. PMID: 7782892, Markowiak P, Śliżewska K. Effects of Probiotics, Prebiotics, and Synbiotics on Human Health. Nutrients. 15 September 2017;9(9):1021. doi: 10.3390/nu9091021. PMID: 28914794; PMCID: PMC5622781.).
  • In Crohn’s disease and other IBDs, certain prebiotics reduce inflammation and improve gut comfort (Lindsay JO, Whelan K, Stagg AJ, Gobin P, Al-Hassi HO, Rayment N, Kamm MA, Knight SC, Forbes A. Clinical, microbiological, and immunological effects of fructo-oligosaccharide in patients with Crohn’s disease. Gut. 2006 Mar;55(3):348-55. doi: 10.1136/gut.2005.074971. Epub 2005 Sep 14. PMID: 16162680; PMCID: PMC1856087.),
  • Inulin helps to increase calcium absorption (Bovee-Oudenhoven IM, Termont DS, Heidt PJ, Van der Meer R.

Gut. 1997 Apr;40(4):497-504. doi: 10.1136/gut.40.4.497. PMID: 9176078; PMCID: PMC1027125.),
  • Prebiotic polysaccharides (e.g. arabinoxylans) improve glycaemic control in people with type 2 diabetes (Lu ZX, Walker KZ, Muir JG, O'Dea K. Arabinoxylan fibre improves metabolic control in people with Type II diabetes. Eur J Clin Nutr. 2004 Apr;58(4):621-8. doi: 10.1038/sj.ejcn.1601857. PMID: 15042130.).

The Effect of Antibiotic Therapy on the Gut Microbiome

Although antibiotics are an invaluable tool in the fight against bacterial infections, they have a significant impact on our gut microbiome, which is a complex ecosystem inhabited by billions of microorganisms. This microbiome plays a key role in digestion, energy metabolism and the regulation of inflammation, influencing many of the host’s endocrine, nervous and immune pathways.

How Do Antibiotics Affect the Gut Microbiome?

The use of antibiotics, particularly broad-spectrum ones, can lead to significant changes in the composition of the gut microbiome and contribute to its disruption. Even short-term antibiotic treatment can cause:

  1. Loss of diversity: antibiotics can reduce the diversity of the microbiome, which is one of the key indicators of its health. Lower diversity means that the gut is more susceptible to colonisation by pathogens.
  2. Dysbiosis: Antibiotic treatment often leads to dysbiosis, i.e. an imbalance in the microbiome. Typical features of dysbiosis include the loss of certain important taxa and changes in the metabolism of microorganisms.
  3. Reduced resistance to pathogens: a healthy gut microbiome provides natural protection against pathogens by competing for space and nutrients. Antibiotic treatment can weaken this protection, increasing the risk of infections such as Clostridium difficile infection.

Clostridium difficile infection: a serious side effect of antibiotic treatment

One of the most serious consequences of gut dysbiosis following antibiotic treatment is infection with Clostridium difficile. C. difficile can lead to serious health problems, including:

– persistent diarrhoea,

– abdominal pain and cramps,

– fever,

– nausea and vomiting.

In more severe cases, a C. difficile infection can lead to colitis, known as pseudomembranous colitis, which may require hospitalisation. Some cases can result in bowel perforation, sepsis, or even death.

The long-term consequences of antibiotic treatment

The long-term effects of antibiotic use can vary greatly and depend on a number of factors, such as the type and dose of the antibiotic and the patient’s individual characteristics. Potential long-term consequences include:

  1. The development of antibiotic resistance: the use of antibiotics encourages the emergence of resistant strains of bacteria, which may make it more difficult to treat future infections.
  2. Metabolic changes: antibiotics can affect the host’s metabolism by altering the gut microbiome, leading to metabolic problems such as obesity or insulin resistance.
  3. Impact on the immune system: the gut microbiome plays a key role in regulating the immune system. Changes in its composition may contribute to the development of autoimmune and inflammatory diseases.

Preventing the adverse effects of antibiotic therapy using probiotics

To prevent the adverse effects of antibiotic treatment, the use of probiotics—which help protect the gut microbiota—is increasingly recommended. RestorFlora PD is an example of an effective probiotic specifically designed for patients undergoing antibiotic treatment. RestorFlora contains a combination of Bacillus spores and the probiotic yeast Saccharomyces boulardii, which prevent antibiotic-associated diarrhoea and aid in the regeneration of the gut microbiome by increasing the diversity of the microflora and improving its functionality.

The RestorFlora probiotic is particularly effective because:

  1. Bacillus spores are resistant to the extreme conditions found in the digestive tract, which enhances their effectiveness,
  2. support the immune system: Saccharomyces boulardii helps regulate the immune response and reduces the risk of intestinal infections,
  3. help protect against dysbiosis: the strains used in RestorFlora support the microbiome, preventing the depletion of beneficial bacteria and the overgrowth of pathogens.

Conclusions

Understanding the impact of antibiotic treatment on the gut microbiome is key to minimising its adverse effects.

Where possible, targeted antibiotics with a narrower spectrum of activity should be used, and efforts should be made to support the restoration of the microbiome once treatment has finished, for example through probiotics such as Restorflora from Microbiome Labs. This helps to effectively protect the health of our gut microbiome and prevent long-term adverse effects.

Probiotic controversies – part 2 post image

The benefits of probiotics for gut microbiome health

Your gut health and the balance of your microbiome are linked in various ways to every aspect of your health. Spore-based probiotics, such as those contained in Microbiome Labs’ MegaSporeBiotic™, support the gut microbiome in several different ways:

Increased diversity of gut microorganisms and gut restoration

Thanks to their robust protective coating, the unique blend of Bacillus strains contained in the MegaSporeBiotic™ probiotic is able to survive the hazardous journey through your digestive system – allowing them to reach your large intestine intact. Once they reach their destination, these dormant spores can transform into their active forms and begin to replicate and colonise your gut – restoring your gut flora to function optimally.

This increased diversity of microorganisms is one of the keys to creating a balanced and healthy ‘ecosystem’ amongst the microorganisms that inhabit your gut. But this is not the only way in which spore-forming probiotics benefit gut health.

Promotion of other beneficial probiotic strains:

Spore-based probiotics are also well known for their ability to increase levels of beneficial metabolites, including:

  • short-chain fatty acids (SCFAs) – SCFAs are the main source of energy for intestinal epithelial cells. They support the repair and regeneration of the intestinal barrier;
  • lactic acid – it has antibacterial properties and serves as a substrate for the production of SCFAs;
  • conjugated linoleic acid (CLA) – this acid helps prevent obesity, allergies and asthma, and improves the overall functioning of the immune system;
  • bacteriocins – natural ‘antibiotics’ that reduce the population of pathogenic bacteria in the gut;

All these metabolites, in turn, support and promote other probiotic strains present in your gut. This phenomenon of ‘probiotics promoting probiotics’ creates a virtuous cycle that further increases microbial diversity and fosters a thriving gut microbial ecosystem.

A strengthened and impermeable intestinal barrier

The MegaSporeBiotic™ probiotic blend aids in the production and synthesis of vitamins and other compounds (such as SCFAs) that play a role in maintaining the integrity of the intestinal barrier. By increasing the production of these key compounds, spore-based probiotics help to ‘strengthen’ the intestinal barrier and reduce intestinal permeability – enabling the gut to retain potentially harmful toxins and pathogens until they are properly excreted.

The health benefits of the spore-based probiotic MegaSporeBiotic™

Although it is clear that MegaSporeBiotic™ has an extremely beneficial effect on gut health, these health benefits go much deeper. Research has shown that the additional benefits of MegaSporeBiotic™ include:

1. Lowering triglyceride levels:

Studies have shown that daily supplementation with MegaSporeBiotic™ can significantly reduce elevated triglyceride levels – both in the short term, immediately after consuming a meal that raises triglyceride levels, and in the long term. These findings may have significant and exciting implications for managing chronic conditions that affect triglyceride levels.

2. Alleviation of leaky gut syndrome (LGS) symptoms:

Increased intestinal permeability, also known as leaky gut syndrome, can result in endotoxins (toxic compounds found in bacteria) entering the bloodstream – triggering the release of pro-inflammatory cytokines and subsequently increasing overall inflammation. Supplementation with MegaSporeBiotic™ probiotics significantly improves the integrity of the intestinal barrier, whilst substantially reducing markers of inflammation, endotoxin levels and overall inflammation.

3. Protection against liver damage: 

Paracetamol (APAP) – one of the most widely used painkillers and fever-reducers in the world – is also a leading cause of liver toxicity and liver damage. Studies have shown that MegaSporeBiotic™ has significant hepatoprotective properties – reducing levels of liver-damaging compounds and protecting the liver from damage caused by increased or prolonged use of paracetamol.

Probiotic disputes – part 1 post image

If you’re browsing the aisles of a health food shop or doing a quick online search to find out which probiotic supplement to buy, there’s a good chance you’ll be bombarded with dozens of different products – all claiming to offer incredible health-boosting benefits. But how do you sort through all these products and assess which probiotic is right for you?

Choosing the best probiotic for you comes down to one thing: scientific evidence. However, there is one probiotic supplement in particular that is backed by impressive scientific evidence confirming its effectiveness. That is the unrivalled MegaSporeBiotic™ from Microbiome Labs.

Choosing the best probiotic for you comes down to one thing – scientific evidence.

In this post, we’ll look at several studies that highlight just how powerful MegaSporeBiotic™ spore-based probiotics are, and what makes them the best probiotic supplement available on the market. We’ll explore what makes spore-based probiotics so beneficial, and how these unique bacterial strains boost the health not only of the digestive system, but also of the immune and nervous systems. So… let’s dive deeper into this topic!

What are spore-based probiotics?

By definition, probiotics are a class of microorganisms – mainly bacteria – that are beneficial to health. Spore-forming probiotics, also known as spore-forming probiotics, are a subset of probiotics that occur naturally, for example in soil. (Not all beneficial gut bacteria are capable of forming spores. The most common Lactobacillus and Bifidobacterium species cannot do so.)

Before supermarkets came along and before we started focusing on washing our food thoroughly, our ancestors lived close to the land. They ate food from the ground, not from supermarket shelves – which means they regularly consumed these probiotics. So, for most of human history, these spore-based probiotics have evolved alongside us and within us, becoming an integral part of our microbiome.

As the name suggests, spore-based probiotics are unique due to their ability to form a protective barrier known as an endospore. These endospores surround the bacteria, protecting them from harsh environmental conditions and enhancing their ability to survive – which makes these bacterial strains particularly well-suited to surviving and thriving in the harsh conditions of your digestive system.

Types of spore-based probiotics

Whilst there are several types of spore-based probiotics, the most common and effective soil-based probiotics belong to a genus of bacteria known as Bacillus. Within this genus, there are several specific strains that offer particularly significant health benefits. These four strains (which are also found in MegaSporeBiotic™ probiotics) are:

  • Bacillus subtilis, HU58
  • Bacillus clausii, SC-109
  • Bacillus coagulans, SC-208
  • Bacillus licheniformis, SL-307

Each of these strains has a different effect on the delicate ecosystem of microbes that inhabit your gut. 

In the next section of our article on spores, we will outline the scientific benefits of taking spore-based probiotics and their advantages over other commonly available probiotics.

What is the difference between a probiotic and a prebiotic?

Nowadays, gut health and the microbiome have become widely discussed topics. In this context, the terms ‘probiotics’ and ‘prebiotics’ frequently crop up in conversations about health. But what exactly is the difference between these two terms?

What is the difference between a probiotic and a prebiotic? post image

Probiotics: Friends of Your Microbiome

What are probiotics?

Probiotics are live microorganisms, mainly bacteria, that offer health benefits, not just for gut health. These ‘good bacteria’ help restore the balance of the gut microbiota, produce many valuable compounds such as vitamins, antioxidants, fatty acids, natural antibiotics, and even substances that regulate our mental health and mood. They regulate digestive processes, control the inflammatory response and ensure our comfort and well-being.

How do probiotics work?

Probiotics introduced into the body, for example through dietary supplements, support the bacteria already present in the gut. Not all probiotics work in the same way, so it is important to choose the right product for a specific problem. How they work depends on the specific strain. Some probiotics are effective for hormonal issues, others aid iron absorption, regulate bowel movements, minimise the side effects of antibiotic treatment such as diarrhoea, whilst others reduce the levels of pathogenic bacteria such as Helicobacter pylori. The specialists who are most knowledgeable in this field are: gastroenterologists, dietitians and functional medicine specialists.

Examples of the types of bacteria most commonly used in probiotic preparations:

– Lactobacillus,

– Bifidobacterium,

– Saccharomyces boulardii (yeast),

– Bacillus – our brand, Microbiome Labs, specialises in this genus of bacteria – read more on the MegaSporeBiotic probiotic page and find out why they are so unique.

Are fermented foods, yoghurts and kefir probiotics?

Fermented food is not in itself a probiotic, although it may contain probiotic bacteria. Why does fermented food not meet the definition of a probiotic?

For a product to be classified as a probiotic, it must contain live bacterial cultures in quantities sufficient to provide health benefits. In the case of fermented foods, it is not always possible to guarantee a consistent, precisely defined number of live bacteria, as fermentation processes can affect their numbers.

The definition of a probiotic includes specific strains of bacteria, such as Lactobacillus and Bifidobacterium. Fermented foods may contain various bacteria depending on the fermentation conditions, and these are not always the ones considered to be probiotic.

Probiotics should survive the digestive process and reach the intestines in sufficient numbers. Not all bacteria present in fermented foods are able to survive the acidic environment of the stomach and other conditions in the digestive tract. Unfortunately, not all supplements available on the market are capable of doing so. Many of them will not work because they will be digested before they reach their destination. Our probiotics boast a 100% survival rate!

The definition of a probiotic also requires clinical trials to confirm its health benefits. In the case of fermented foods, such trials are not always carried out, and the health benefits may be more closely linked to the fermentation process itself than to the presence of specific probiotics.

Nevertheless, fermented foods such as yoghurt, kefir and sauerkraut may be beneficial to health due to other components, such as vitamins, enzymes and organic acids. Therefore, although fermented foods can support a healthy microbiome, they do not always strictly meet the definition of a probiotic.

Prebiotics: Food for your good bacteria

What are prebiotics?

Prebiotics are food-derived substances that are not digested by the human digestive system but reach the large intestine, where they serve as food for the beneficial bacteria present in the gut.

How do prebiotics work?

Prebiotics pass through the upper digestive tract undigested, reaching the intestines where they act as a food source for beneficial bacteria. By providing nutrients for these bacteria, prebiotics help them to multiply and maintain a healthy microbiome.

Examples of prebiotics:

– Inulin (found in onions, chicory, garlic and asparagus),

– Oligofructose (found naturally in: Jerusalem artichokes, chicory, sunroot, dandelion, garlic, leeks, onions, asparagus),

– Dietary fibre (wholemeal rye products, brown rice, groats, porridge, almonds and fruit),

– Resistant starch (starchy foods that have been cooked and then cooled (potatoes, pasta, rice) and stale bread).

The differences between probiotics and prebiotics

1. Nature:

   – Probiotics are live microorganisms.

   – Prebiotics are dietary substances that are not digested by the human body.

2. Function:

   – Probiotics introduce beneficial bacteria into the body.

   – Prebiotics provide nourishment for these bacteria, enabling them to function properly and thrive.

3. Sources:

   – Probiotics are available in the form of supplements, whilst probiotic bacteria are also found in fermented foods.

   – Prebiotics are found in certain plant-based foods.

Summary

In short, probiotics are beneficial microorganisms (mainly bacteria) that are essential for health, whilst prebiotics are dietary substances that serve as food for these bacteria. Both are crucial for maintaining a healthy microbiome and supporting overall gut health. Adding both probiotics and prebiotics to your diet can help maintain the balance of gut flora and improve your overall health.

In recent years, our understanding of how the microorganisms in the gut affect the condition of our skin has expanded significantly. One condition that has attracted particular interest in the context of research into the gut-skin axis is psoriasis.

What is psoriasis?

Psoriasis is a chronic inflammatory skin condition of autoimmune origin; according to statistical data, approximately 700,000 people in Poland suffer from it. It is characterised by uncontrolled proliferation and dysfunctional differentiation of keratinocytes, which manifests clinically as the presence of characteristic scales (plaques). Histologically, psoriatic plaques show epidermal hyperplasia covering inflammatory infiltrates of skin dendritic cells, macrophages, T lymphocytes and neutrophils. Tumour necrosis factor α (TNF-α), interferon γ (IFN-γ), interleukin (IL)-23/IL-17A and IL-22 are the main immune molecules responsible for keratinocyte proliferation, inflammation and increased cytokine levels in psoriasis.

The role of gut dysbiosis in autoimmune diseases

There is growing evidence that gut dysbiosis plays a key role in autoimmune diseases, including psoriasis, as it leads to an increase in the levels of these pro-inflammatory molecules circulating in the blood and an exaggerated immune response.

A clinical trial investigating the effect of probiotic and prebiotic therapy as an adjunct to the treatment of psoriasis

In today’s post, we will take a closer look at an interesting and promising clinical trial, the results of which were published in July 2023 in the *International Journal of Molecular Sciences* in an article entitled “Probiotics and Prebiotics as Novel Therapeutic Approaches in the Treatment of Psoriasis” (original title: “Transforming Psoriasis Care: Probiotics and Prebiotics as Novel Therapeutic Approaches”) 

The study demonstrated that supplementation with probiotics containing spores of the genus Bacillus (Bacillus indicus HU36, Bacillus subtilis HU58, Bacillus coagulans SC208, Bacillus licheniformis SL307, and Bacillus clausii SC109) and prebiotics  (fructo-, xylo- and galacto-oligosaccharides) may bring significant benefits to patients with psoriasis receiving concurrent topical therapy and may represent a new therapeutic strategy. Improvement in the gut microbiome profile leads to significant alleviation of psoriasis symptoms and an improved quality of life.

In the study cited, combined supplementation (prebiotics + probiotics) led to beneficial changes in metabolism, the immune system and the gut microbiota:

  • increasing the diversity of the gut microbiome, 
  • an increase in the number of bacterial species considered beneficial (including an increase in Faecalibacterium prausnitzii and Lactobacillus spp),
  • an increase in short-chain fatty acids,
  • improved intestinal barrier integrity,
  • a reduction in the levels of pro-inflammatory cytokines (TNF-α, IL-6, IFN-γ) and bacterial endotoxin (LPS), and consequently a reduction in inflammation,
  • an increase in the level of the cytokine IL-10 (a suppressor of the cellular immune response),
  • a significant improvement in patients’ quality of life (a reduction in the DLQI – Dermatology Life Quality Index),
  • a significant reduction in skin symptoms (a decrease in the PASI score – Psoriasis Area and Severity Index, a measure of the extent and severity of skin lesions in psoriasis),
  • improvement in lipid profile (reduction in triglyceride levels, improvement in the LDL:HDL ratio),
  • reduction in uric acid levels (patients with psoriasis, particularly those with severe forms of the condition, are at greater risk of hyperuricaemia).

Summary

In summary, supplementation with probiotics and prebiotics improved the overall health of patients with psoriasis who were receiving topical anti-psoriatic treatment. Firstly, supplementation with probiotics and prebiotics significantly improved quality of life, as evidenced by a reduction in PASI and DLQI scores. Secondly, the BMI and FFM of patients in the intervention group were significantly reduced. Thirdly, supplementation with prebiotics and probiotics promoted an anti-inflammatory response and contributed to symptom improvement in the intervention group by regulating cytokine activity. Furthermore, at the end of the study, the intervention group had significantly better metabolic markers compared to the control group, including lower levels of total cholesterol, LDL-C, triglycerides and uric acid; HDL-C levels increased. Finally, supplementation increased gut microbiota diversity (as indicated by a higher Shannon index), increased the Firmicutes/Bacteroidetes ratio and acetate/propionate production, and reduced the Prevotella/Bacteroidetes ratio and the number of LPS-positive bacteria. Furthermore, there was a reduction in the number of Bacteroidetes spp., Prevotella spp., Prevotella copri and Clostridium difficile, whilst levels of Akkermansia muciniphila, Verrucomicrobia and Ruminococcus spp. increased.

However, further clinical trials are needed to fully elucidate the potential benefits of probiotics and prebiotics in psoriasis and to identify the most effective combination and dosage.

Leaky gut: What does it mean? Causes and symptoms

Leaky gut: What does it mean? Causes and symptoms

Have you ever wondered what the term ‘leaky gut’ means? The term may seem rather mysterious, but this condition is a reality for many people.

Leaky gut: What does it mean? Causes and symptoms post image

Leaky gut, also known as leaky gut syndrome or intestinal permeability, is a condition that can lead to a range of health problems affecting both the digestive system and other parts of the body.

What does ‘leaky gut’ mean?

Leaky gut is a condition in which the intestinal barrier – our first line of defence against harmful substances from the food we eat and the environment – begins to ‘leak’. This means that small molecules, which would normally be retained by the intestinal mucosa, begin to enter our bloodstream. As a result, the body begins to react to these substances as if they were intruders, which can lead to inflammation, allergies, hypersensitivity and many other health problems.

Symptoms of leaky gut

Leaky gut syndrome is not easy to diagnose, as symptoms can vary and do not necessarily point directly to an intestinal problem. However, there are a number of symptoms that may indicate leaky gut. Here are some of them:

– digestive problems, such as diarrhoea, constipation, bloating, flatulence,

– chronic fatigue,

– joint pain,

– skin problems such as acne, eczema or a rash,

– food intolerances,

– sudden fluctuations in weight.

It is important to note that the above symptoms may indicate a wide range of health issues, not just leaky gut. If you are experiencing any of these symptoms, you should consult your doctor and a dietitian. 

Leaky gut: causes

There are many different factors that can contribute to the development of leaky gut. Some of these include:

– a highly processed diet containing preservatives, high in sugars and saturated fats, and low in fibre,

– chronic stress,

– alcohol,

– certain medicines, such as non-steroidal anti-inflammatory drugs (NSAIDs) and antibiotics (even those taken a long time ago),

– various types of infections, including parasitic infections,

– disturbances in the gut microbiota (intestinal dysbiosis).

Understanding the phenomenon of leaky gut is key to maintaining gut health. Remember that the best way to manage this condition is to prevent it; a healthy, balanced diet, regular exercise, stress reduction and moderate alcohol consumption are just some of the steps we can take to look after our gut health. If you suspect you may be suffering from leaky gut, consult a doctor who can help you identify the root causes and create a treatment plan tailored to your needs.

Supplementation in Leaky Gut Syndrome

The right supplements can support the regeneration of the intestinal barrier, increase the population of beneficial microorganisms and limit the growth of pathogens, reduce inflammation and improve overall digestive function.

According to the article, there are several supplements that may be beneficial for people with leaky gut. Here are some of them:

  1. MegaSporeBiotic™ – a unique probiotic with a proven 100% survival rate in the digestive system, meaning it is not harmed by digestive acids, bile or antibiotics taken at the same time. It contains strains that form endospores and reach their destination intact, where they create optimal conditions for the restoration of beneficial microbiota.
  2. MegaPre™ – a prebiotic, or, to put it simply, ‘food’ for our beneficial microbes. It consists of indigestible fibres, which provide the good bacteria with better conditions in which to thrive and fulfil their role in regulating the digestive and immune systems. 
  3. MegaMucosa™ – a postbiotic formulated specifically to support the mucous membrane. It contains the amino acids needed to build the intestine’s protective layer, as well as bioflavonoids with antioxidant and anti-inflammatory properties.

It is also worth including ingredients such as L-glutamine, butyric acid, curcumin and omega-3 fatty acids, and ensuring adequate levels of vitamin D3 – which is essential for the proper functioning of the immune system.

Lifestyle

The changes you’ll need to make if you want to improve your gut health primarily relate to diet, your circadian rhythm and stress. This means incorporating nutrient-rich foods into your diet that contain: protein, vitamins, minerals, antioxidants, unsaturated fatty acids and dietary fibre. Meal times, fasting between meals and overnight, and proper hydration are also important. 

The circadian rhythm is often overlooked and not directly associated with gastrointestinal therapy. This is entirely unjustified, as it plays an invaluable role in regulating the brain-gut axis. To regulate it, ensure you have the right conditions for sleep, limit your exposure to blue light for 2–3 hours before going to bed, don’t go to sleep too late, and don’t sleep for less than 7–8 hours. 

Stress management. Look after your mental wellbeing; check your environment for stressors (e.g. toxic relationships). If you need to, seek psychotherapy; make sure you get enough rest and find time for activities that help you relax. Research shows that contact with nature and physical activity are also very important in this regard. Don’t neglect them!

Summary

A multi-pronged approach to the problem is in line with the principles of functional medicine – also known as holistic medicine – and will bring you the best and most lasting results. Remember, however, that you need to be patient, kind to yourself and open to change. This mindset will not only transform your gut health but also improve your overall well-being. We’re keeping our fingers crossed for you!

Why is the microbiome important for the body?

Immunity and infectious diseases – the key role of the microbiome

Although there has been a lot of talk and writing about the microbiome recently, not everyone knows exactly what the microbiome is or what role it plays in our body’s immune response, particularly when it comes to our immunity or the healing and recovery process.

Why is the microbiome important for the body? post image

Immunity and infectious diseases – the key role of the microbiome

The Human Microbiome Project has revealed that each microbiome contains up to 3.3 million unique protein-coding genes. This growing field of research continues to highlight the importance of the microbiome and the extent of its influence.  One ongoing area of research is its relationship with immunity. It is now accepted that a balanced microbiome is crucial for the proper development and functioning of the immune system, which helps explain why 80% of our immunity is located in the gut.  In 2018, researchers Libertucci and Young proposed a new function of the microbiota: the ability to shape susceptibility to infectious diseases and their outcomes.

A healthy microbiota is designed to prevent the growth, persistence and subsequent infection by foreign microorganisms (resistance to colonisation). Our native microbiota directly inhibits all pathogens through its own protective mechanisms, and indirectly assists by signalling the host’s immune system to mount a defence.  

The role of the gut-associated lymphoid tissue (GALT)

The immune system of the intestinal mucosa plays a key role in this. Its defence mechanisms include: the secretion of antimicrobial peptides (AMPs) and the dynamic and adaptive production of targeted immunoglobulins in response to pathogenic threats. It is now known that the bacterial composition of our microbiome has a direct impact on all these elements. 

Protein complexes, on whose quality the integrity of the intestinal barrier depends, can be impaired in the presence of certain bacteria, such as C. difficile or Yersinia enterocolitica. The amount of mucin, the main component of our mucus layer, increases in the presence of certain commensal bacteria, such as E. coli, but is degraded in the presence of, for example, C. difficile.  AMP production is increased by certain commensals, such as Bacteroides thetaiotaomicron and Bifidobacterium breve, as well as in the presence of short-chain fatty acids (SCFAs). AMP (antimicrobial peptides) secreted by intestinal mucosal cells form part of our innate immune system. They protect epithelial cells by binding to and damaging the cell membranes of bacterial pathogens and by inhibiting viral replication.  Another innate immune defence is secretory IgA antibodies, the secretion of which also depends on a properly functioning microbiome and may increase in the presence of certain commensal bacteria, such as Lactobacillus reuteri.   

Inducing a targeted immune response

Our targeted adaptive defence against pathogens occurs through the production of antibody-producing cells (APCs).  T and B lymphocytes proliferate in an area known as Peyer’s patches, located in the ileum and forming part of the GALT. Commensal gut microorganisms are essential both for the maturation of these secondary lymphoid organs and for alerting them when they need to be on the lookout for an impending threat.

This means that any disruption to the microbiome can result in altered immunity and increased susceptibility to infections. For example, the administration of antibiotics can significantly deplete the microbiome and predispose individuals to C. difficile infection.   Impaired barrier function may allow lipopolysaccharides (LPS), a structural component of Gram-negative bacterial cell membranes, to be released into the bloodstream, which may continuously activate our immune system and lead to the low-grade chronic inflammation observed in many conditions.

When it comes to viruses, the interactions between them and the commensal microbiota are not so clear. We know that in healthy individuals there are groups of viruses that are not pathogenic, known as the human virome.  These viruses use evasion mechanisms to enable tolerance by the immune system (a strategy unfortunately also used by pathogenic viruses) and can modulate the immune response.

The protective role of bacteria

It has been shown that certain bacteria protect against specific viral pathogens. Bacteria of the genus Lactobacillus inhibit the growth of norovirus in mice, whilst Bifidobacterium breve inhibits rotavirus. The gut microbiota may also trigger antiviral defence mechanisms in distal sites, such as the lungs.  It has been shown that gut probiotics, such as Lactobacillus paracasei and plantarum, influence inflammatory responses during influenza virus infection. This is a relatively new field of research, which will undoubtedly gain momentum with the emergence of COVID-19.

Optimisation of microbial defence

So, to optimise the functioning of our microbiome to protect us against infectious diseases, there are many things we can all do.  Minimising alcohol consumption, giving up smoking and managing stress will have a really positive impact. When it comes to diet, research suggests that we need to expand our diet to include a variety of plant-based foods and reduce our intake of saturated fats. 

There are also certain therapeutic objectives that we can pursue: modulating the microbiome using targeted probiotics, prebiotics and polyphenols; increasing secretory IgA levels; and boosting mucin production. 

The use of probiotics, prebiotics and polyphenols.

It has been shown that certain probiotics strengthen the protective barrier.  A double-blind, placebo-controlled study using MegaSporeBiotic showed that 30 days of supplementation can reduce endotoxemia from leaky gut following a high-fat meal by 45%, as well as significantly lowering levels of inflammatory cytokines.  (McFarlin et al., 2017) Many probiotics struggle to survive the harsh passage through the stomach, but spores can and do reach the gut fully viable, thereby producing a more lasting and stable effect. These studies suggest that spores were able to strengthen the integrity of the intestinal lining, keeping endotoxins out of the bloodstream.

Another way to beneficially modulate the microbiome is to promote the growth of keystone species, such as Akkermansia municiphilia and Faecalibacterium prausnitzii, as well as Bifidobacteria, using carefully selected prebiotics consisting of engineered oligosaccharides. It has been shown that keystone bacteria help maintain the balance of the microbiome and also improve the function of tight junctions between intestinal cells.

Other studies have highlighted the importance of polyphenols (PPs) and their metabolites in modulating the microbiome and barrier function through their antimicrobial, antioxidant, anti-inflammatory and antiproliferative effects, both at the intestinal and systemic levels.  They can improve the composition of the microbiota and also counteract pro-oxidative and/or pro-inflammatory reactions.

Protection of the intestinal mucosa

Increasing the secretion of immunoglobulins, which bind to and neutralise toxins in the lumen and mucosa before they reach the intestinal epithelium, may also be effective.  Nutrients have been shown to have a positive effect on their production and secretion, including essential omega fatty acids, glutathione, glycine, phosphatidylcholine, vitamin C, zinc and colostrum.

Another approach is to increase mucin production in order to strengthen the mucus layer lining the intestinal epithelium.  Nutrients that have been shown to do this include the amino acids L-threonine, L-serine, L-proline and L-cysteine, where, in one study on rats, supplementation with these increased production by 95%. They are available in our MegaMucosa supplement

Summary

In summary, our microbiome plays a key role in how each of us responds to an infectious disease. However, there are steps, as described above, that we can take to boost our immune function.
