Just How Beneficial Is ‘Good’ Bacteria to the Body?

It’s quite well known that the good bacteria of our internal microbiome help to support the health of the digestive system. However, recent research has highlighted other areas where using specific good bacteria could support other areas of health and wellbeing. This includes intimate health, skin health, mood and memory.

Good bacteria for mood and memory

In the last decade, it has been revealed that the brain and the gut are in constant communication with each other. This has led to a field of research known as ‘psychobiotics’, investigating the link between the gut flora and the development of psychological problems (1).

Specific bacteria shown to be helpful for mood and memory
  • Studies have indicated that probiotic treatment can induce behavioural and psychological changes, including improved memory and reduced anxiety (2). The strains with the most consistent research include Lactobacillus casei, Lactobacillus rhamnosus, Lactobacillus acidophilus and Bifidobacteria bifidum.
  • In a study on chronic fatigue syndrome, supplementation with L. casei was linked to a significant decrease in anxiety symptoms (3).
  • L. rhamnosus has been shown to reduce stress induced anxiety and depression (4).
  • A study providing L. acidophilus, L. casei and B. bifidus (2 billion of each) over 8 weeks: The patients who had received the probiotic combination had significantly decreased total scores on the Beck Depression Inventory. In addition, they had significant decreases in systemic inflammation (2,5).

Good bacteria for intimate health

Vaginal infections affect 300 million women worldwide:

  • 75% of women will suffer thrush at least once in their lives and over 5% will suffer recurrent episodes more than 4 times a year.
  • Bacterial Vaginosis (BV) is actually the most common cause of vaginal infections in women of childbearing age, affecting up to 84% women. BV in some women may also produce irritation and discomfort. Left untreated BV can lead to infertility and premature labour.

Treatment for BV (antibiotics) can lead to the overgrowth of candida, resulting in thrush. Likewise, treatments for thrush can lead to dysbiosis in the vaginal flora, resulting in a change in vaginal pH leading to BV. Therefore, a product which can address both issues, without the need for a woman to know which infection she has and offering prevention as well as treatment of both, will help to break the vicious cycle many women find themselves in.

Specific bacteria researched for intimate health

A combination of Lactobacillus rhamnosus, Lactobacillus plantarum and Bifidobateria animalis subsp. lactis has been extensively researched for their role in the maintenance of vaginal pH and control of bacteria and yeasts, and has been shown to be effective against both thrush and BV infections.

In a trial carried out using L. rhamnosus, L. plantarum and B. animalis subsp. lactis the women who were using the supplement reported effective relief from:

  • Itching
  • Burning
  • Discharge
  • Dryness (6)

Good bacteria to support skin health

The link between skin health and the health of the gut is not new. Researchers as far back as 1930 suspected a link between gut health and skin health – modern research though, has confirmed the importance of this relationship.

This means that good bacteria could be very helpful in reducing the severity of all manner of skin complaints.

Did you know?
    • 40% of those people who suffer with inflammatory bowel diseases, also struggle with some form of skin disorder.
    • Unbalanced gut flora is 10 times more common in those people who are suffering with acne rosacea.
    • Many skin conditions including acne rosacea, psoriasis and dermatitis have now been shown to be linked to increased levels of unfriendly bacteria in the gut.
Specific good bacteria researched for benefits in skin health

A combination of Lactobacillus plantarum, Lactobacillus reuteri and Lactobacillus rhamnosus, has been extensively trialled for its action on skin health. This specific combination has been found to inhibit the following pathogens: (7)

  • Staphyloccocus aureas – responsible for skin infections, pimples, impetigo, boils, abscesses and cellulitis. The combination of bacteria can inhibit this pathogen within 24 hours.
  • Pseudomonas aeruginosa – responsible for inflammation, sepsis, skin infections and dermatitis. The bacteria are strongly effective in reducing this pathogen within just 3 hours and they maintain their inhibitory effect for over 24 hours.
  • Propionibacterium acnes – responsible for skin discomforts such as acne vulgaris and oily skin. The bacterial combination has been shown to have the ability to inhibit this bacteria within 48 hours with a continued reduction over 7 days.
  • Staphylococcus epidermis – an opportunistic pathogen responsible for unbalanced skin microbiota and the worsening of skin conditions. The 3 strains reduced levels of this pathogen within 3 hours.

Prebiotics vs Probiotics – What’s the Difference?

What’s the Difference Between Prebiotics and Probiotics?

You might have heard of the terms ‘prebiotics’ and ‘probiotics’ being mentioned in association with digestive health on BBC television show “Trust Me I’m A Doctor”. But what’s the difference between them and which one is more important?

Our digestive tract contains high amounts of probiotics ‘beneficial bacteria’, which play a vital role in supporting the optimum function of our digestive system. They do this via many various mechanisms including supporting digestion and enhancing our gut immunity.

Prebiotics

The best way to look after our gut bacteria is by feeding it well and the best foods for it are known as ‘prebiotics’. Prebiotics (also known as dietary fibre) are the indigestible components of food that are able to reach the large intestine (where most of our gut bacteria resides) to feed our beneficial bacteria to promote its growth and function. We are recommended to consume 30g of fibre daily, however, due to the introduction of the western diet which is high in processed and refined foods and contains very little fibre, the current average intake of fibre in the UK is 18g/day.

The main food sources of prebiotics include vegetables and fruits such as artichokes, garlic, leeks and onions and fermented foods such as kefir. Prebiotics are also available in the form of food supplements such as ‘fructooligosaccharides’ (FOS) and inulin.

FOS and Inulin

Research indicates that FOS and inulin are some of the most beneficial types of prebiotics for feeding our gut bacteria. They belong to the same family of fructo-polysaccharides, and the primary difference between them is that inulin is a longer chain fructo-polysaccharide than FOS. Although they both have very similar effects in terms of promoting the size, diversity and physiological functions of our gut bacteria, some research indicates that FOS may exert a broader therapeutic benefit than inulin. Both of these can be naturally derived from chicory, they are naturally sweet and can be used as a healthy alternative to sugar when the powder is sprinkled over food such as porridge for example.

Probiotics

Common modern lifestyle choices such as alcohol consumption, processed food intake and antibiotic use can impact negatively on the levels of our beneficial bacteria, hence the growing interest in the use of microbial preparations to supplement the diet known as ‘probiotics’. Therefore, although feeding our bacteria with prebiotics is important, it’s just as important to have the right balance of beneficial bacteria to be fed in the first place, which is why both probiotics and prebiotics are just as important as each other.

Optibac Probiotics – travel with a happy and healthy digestive system

50% of travellers experience digestive issues when abroad. Don’t be one of them!

Traveller’s Diarrhoea is the most frequently experienced health disorder experienced by those travelling abroad[1]. Research suggest that pathogenic bacteria are responsible for 85% of all cases of Traveller’s Diarrhoea[3], with E. coli being the most common offender[4,5]. Despite it being a generally minor condition, it can ruin your holiday. Statistics reveal that 20% of sufferers are confined to bed for a day, and 33% need to stop their activities[2].

Of course some destinations are higher risk than others and are generally the more exotic locations such as Egypt, India, and Mexico.

So what is the best natural approach to Traveller’s Diarrhoea?

Much research shows the potential for probiotics to be a natural preventative. Studies suggest that probiotics, a.k.a. friendly bacteria, can help to strengthen the gut’s protective barrier against pathogenic bacteria, such as E. coli and Salmonella. A review of the research on this (meta-analysis) found that 85% of cases of Traveller’s Diarrhoea were prevented by probiotics[7].

How can taking bacteria avoid a bacterial infection?

Well as with other issues with gut health, having enough of the relevant strain of bacteria will help fight the unwanted pathogenic bacteria. It has been found that a combination of B. longum Rosell-175, Lactobacillus rhamnosus Rosell-11, Saccharomyces boulardii and L. acidophilus Rosell-52 have been shown to be effective in preventing infection with E. coli[8]. Other trials also show that Saccharomyces boulardii may be especially helpful in cases of Traveller’s Diarrhoea due to its unique ability to actually bind to unwanted, pathogenic bacteria and then help excrete them, as well as its documented ability to alleviate diarrhoea during an infection [9,10,11,12].

L. acidophilus Rosell-52 & L. rhamnosus Rosell-11 have also been shown to help prevent infection by less common pathogens including: P. aeruginosa, Klebsiella, and Staphylococcus [13,14].

So all in all these bacteria can be of huge help staying happy and healthy when travelling. Nutritional Therapist, Joanna Lutyens from OptiBac Probiotics says ‘ Your digestive system may be under siege when travelling abroad, both from an intake of foods which your body is not used to, as well as a whole new range of bacteria. It is therefore really important to look after your digestive health when travelling. Taking a probiotic specifically designed to support your gut health in this situation may really help prevent discomfort or illness. Of course there are other things you can do to avoid getting the dreaded Delhi Belly. Tips include avoiding unpeeled fruit and vegetables, avoid tap water even when brushing your teeth, wash your hands regularly, avoid ice cubes and stay hydrated.’

Optibac: Children and probiotics

There’s a lot of buzz about the benefits of bacteria in the media, particularly for children, but this can be a confusing issue for many people. Why would you ever want to give your child bacteria to improve their health? Aren’t bacteria bad for us, causing infections and stomach upsets?

The simple answer is No! Not all bacteria are bad; in fact mounting evidence suggests that starting out with a healthy balance of friendly flora in their intestines could help to improve your child’s health and actually reduce the risk of infections and other health conditions as they grow up. Even better, having plenty of good gut flora (bacteria) is being linked to good long-term health.

So how do these microscopic microflora help to improve your child’s health?

It may seem weird, but the average human being is a home to literally trillions of bacteria who live all over our bodies, but most plentifully in the moist, warm areas in our intestines. Symbiotic, or ‘friendly’ bacteria are those that live in harmony with our bodies – we provide them with a home and food to eat, and they in turn offer us a host of health benefits.

Though we are typically born without any bacteria in residence, they begin to colonise in our bodies within a few days of birth. The first bacterial settlers are passed on to babies by their mother as they pass down the birth canal during a normal vaginal delivery.

These tiny passengers have been shown to have many positive effects in the body ; they work with the immune system helping to modulate immune responses, reducing the risk of allergies and protecting against infections and viruses. They help to improve digestive function, alleviating diarrhoea or constipation and helping to improve metabolism and nutrient absorption.

Studies have indicated that numerous health benefits may be seen in children who were given probiotic supplements, including a reduction in childhood illnesses and allergic symptoms such as eczema.

If children take on beneficial bacteria during birth, why are probiotic supplements necessary?

In an ideal world, we wouldn’t need to give supplements, but many factors can affect the integrity of a child’s gut flora. If the mother’s intestinal flora is compromised in any way, then the bacteria passed on to a baby may be unbalanced from the start. Vaginal infections during pregnancy, antibiotics, poor diet and even stress can all impact the delicate populations of probiotic bacteria in our intestines.

Additionally, those babies delivered by Caesarian section will not have the benefit of bacteria from mum, and often suffer from digestive problems or allergies such as eczema as a result. Any antibiotics given to your baby or child will kill off good as well as bad bacteria, and consequently can negatively affect their populations of friendly flora.

Why use supplements?

Isn’t it enough just to give your child yoghurt every day?
It’s true that fermented foods such as yoghurt, kefir and sauerkraut have formed an important part of the human diet in most cultures for hundreds of years, and it’s still a good idea for most people to include these as part of a healthy diet.

But it’s often difficult to ascertain the levels of bacteria present in fermented foods; which species are present and how viable they are once consumed. Many of the bacteria found in fermented foods are typically ‘transient’, meaning that they have beneficial effects as they pass through the digestive system, but can’t be guaranteed to become resident in the intestines and restore the balance of flora present.

The bacterial strains used in OptiBac Probiotics products undergo stringent tests that guarantee they will adhere to the intestinal wall, and form new colonies, meaning that they’re likely to offer longer-lasting health beneifits.

So where do we find these so-called ‘friendly bacteria?’ in a supplement form?

The good news is that the folk at OptiBac Probiotics have made it very easy for you to add probiotic bacteria into your child’s daily healthcare regime.

They offer a specific product designed to be taken by children from 0-12 years, which comes in a powder neatly packaged in a handy sachet form. Unlike many other similar products, the sachets do not require refrigeration and are easy to add to a little water, milk or yoghurt.

To ensure that really helpful species of bacteria are passed on to their babies, we also recommend that mums-to-be take ‘For babies & children’ during the final trimester of pregnancy.

Breast-feeding mums can continue to take the product as evidence suggests that the bacteria continues to be passed on to baby via breast milk, or the product can be given directly to infants from birth.

Bifidobacteria infantis has been identified as one of the early settlers in a healthy child’s gut, which is why it is included in ‘For babies & children’ which is gluten-free and suitable for those with lactose intolerance.

So the question is not why would you give your child probiotic bacteria, but given the evidence supporting their use, why wouldn’t you?

Probiotics and Children’s Immunity

A recent placebo-controlled trial has found that a combination of probiotics and vitamin C helps to prevent cold infections in young children.

The study, published last month in the European Journal of Clinical Nutrition, involved 69 preschool children who each received either a placebo supplement or a chewable probiotic and vitamin C supplement for a period of six months. The study was double-blind, meaning that neither the researchers nor the children or their parents knew whether each child was taking the supplement or a placebo.

The results at the end of the six month period were promising. The children who received the probiotic and vitamin C supplement had experienced fewer upper respiratory tract infections (ie common colds), and as a result had fewer absences from preschool and fewer visits to the doctor. The probiotic and vitamin C group were also less likely to have taken antibiotics, painkillers, cough medicines or nasal sprays compared with those children in the placebo group.

Both probiotics and vitamin C are known to modulate the immune system. Vitamin C, a powerful antioxidant, reverses oxidative damage caused by infection. It is also believed to support production of phagocytes, cytokines and lymphcytes – cells that battle infection.
Healthy probiotic bacteria ramp up the body’s production of antibodies and lymphocytes, defending the body against infection (2).

In fact, around 70% of the body’s immune system resides in the digestive system which is home to around 100 trillion (about 3lbs) bacteria.

This particular study used 50mg of vitamin C alongside Lactobacillus acidophilus, Bifidobacterium bifidum and Bifidobacterium lactis strains of probiotics. Other strains of probiotics have also been linked with increased resistance to infection, though more research needs to be done in order to determine which particular strain is most effective. Hopefully this study will pave the way for larger trials to be carried out. In the meantime, probiotics have repeatedly been demonstrated as a safe supplement for children, and so trying a probiotic supplement with vitamin C would seem a sensible measure for parents of children who seem to have one cold after another.

Ideally, all children should all eat a diet which is rich in vitamin C and other anti-oxidants, and encourages growth of healthy bacteria. This means eating plenty of fruits and vegetables, and avoiding foods that deplete levels of healthy bacteria such as sugar and white grains. Unfortunately children’s sugar intake is consistently above the maximum recommended amount, and only around 10% of children in the UK manage to eat their ‘5-a-day’ requirement of fruit and vegetables (3).

Especially good sources of prebiotics – foods which feed and therefore boost probiotic bacteria – include leeks, onions, garlic, asparagus and bananas. Natural probiotic yoghurt can also help to support children’s levels of healthy bacteria. Most added sugar comes from breakfast cereals and soft drinks, and so parents should look out for these items in particular, and read labels to check from hidden sugars.

Boosting vitamin C intake and reaching the 5-a-day recommendation means adding fruits and vegetables to meals and snacks – for children, small changes such as adding blueberries to breakfast or pureeing vegetables into pasta sauces are simple changes that can make a huge difference, ensuring that children are happy and healthy both in and out of school.

Natural Remedies for Women’s Intimate Health

Want natural remedies for women’s intimate health? Try Probiotics.

Us women are great at talking about nearly everything you can think of. However, despite the fact that most women will suffer from thrush, cystitis and / or bacterial vaginosis (BV) during their life time, it appears that intimate health is something we are all apparently too shy to talk about.

The facts are that 75% of women suffer from thrush once in their lifetime, 50% suffer from cystitis at least once and BV affects 1 in 3 women with a high rate of recurrence. Typically these are treated with topical ointments which tend to give just temporary relief, or antibiotics and antifungals which can result in recurrence and can make you feel unwell.

So how and why does having a good balance of friendly bacteria in the intimate area help alleviate and prevent these conditions? Well there is a lot of research behind this.

Thrush is usually caused by the yeast fungus Candida albicans which usually lives harmlessly on the skin and in the mouth, gut and vagina. However, sometimes this yeast becomes overgrown, resulting in thrush. The causes of BV are similar, stemming from a change in balance of bacteria in the vagina as well as a more alkaline pH. And again cystitis is caused by a bacterial infection and interestingly occurs more often in menopausal women due to the lower oestrogen levels.

So in a nutshell, it’s about bacteria! How can probiotics help? The issue with typical treatments are that they do not replenish the healthy bacteria and antibiotics not only knock our good bacteria further out of kilter but also multiple use can lead to antibiotic resistance. Probiotics help replenish our healthy bacteria. But it’s important to note that not all probiotics contain the correct strains of bacteria which are specifically required for these specific intimate issues.

Certain probiotic strains have been trialled and have been shown to increase the efficacy of standard treatments, as well as lowering the risk of recurrence. In particular 2 specific probiotic strains, L. reuteri RC-14® and L. rhamnosus GR-1® are well documented in women’s health, with over 30 years of scientific evidence. OptiBac Probiotics ‘For women’ is a brand new, unique supplement that contains these specific strains and has had significant trialling in itself.

In one trial, participants with thrush took an antifungal capsule with either ‘For women’ daily or placebo for 4 weeks. At follow-up those who had been taking ‘For women’ had 70% fewer symptoms and yeast cell counts than the placebo group.1

In another trial, 252 women who suffered with recurring UTIs took ‘For women’ or antibiotics (trimethoprim-sulfamethoxazole) for one year. After 12 months the number of UTIs had more than halved in both groups, with ‘For women’ being almost as effective as antibiotics. (An impressive result for a natural remedy)2

OptiBac Probiotics ‘For women’ works via several mechanisms: It colonises the vagina, crowds out candida by competing for space and nutrients, fortifies women’s natural defences against Candida , inhibits E. Coli, produces bactericocins which kill pathogens and E. Coli, restores a healthy pH of <4.5, and produces a substance which breaks down the pathogens defensive biofilm.

Taking these strains of bacteria is clearly an impressive start to improving symptoms as well as preventing recurrence. But are there any other natural remedies which can help?

  • When rebalancing our bacteria it’s always a good idea to stay away from sugar and yeast containing foods and drinks which can feed the growth of yeast and bad bacteria, this of course includes alcohol and fruit juices, except low sugar Cranberry which can help in the case of cystitis
  • Drink plenty of water and reduce your coffee
  • Ideally if you have thrush, try to include antifungal foods in your diet such as garlic, coconut oil, ginger and cinnamon among others.
  • Avoid using soaps and douches in the intimate area and swap nylon for cotton underwear and avoid perfumed sanitary products
  • Urinating before and after sex can help with cystitis.
  • The pill can sometimes upset intimate flora – talk to your doctor about alternative contraception

OptiBac Probiotics ‘For Women’ can be taken alongside standard treatments to increase the effect of standard treatments, but is also recommended as a continual method of prevention if a recurrence is an issue. So, if you’re looking to support your intimate health, take a look at OptiBac Probiotics ‘For women’.

Probiotics, our friends inside

The human intestinal tract is home to trillions of “friendly” bacteria that are crucial in maintaining good health. These bacteria are instrumental in protecting against tummy problems, supporting digestion and absorption of nutrients. The balance of this gut micro flora is also intrinsically linked with immunity, ensuring a positive balance of beneficial gut bacteria will give your immune system a fighting chance of beating off the majority of opportunistic pathogens.

Antacids, antibiotics and low fibre refined diets all disrupt this delicate balance. This is possibly why an estimated 1 in 5 adults in the UK suffer from gastrointestinal complaints. Rebalancing the gut micro flora through the diet or by taking a “probiotic” supplement containing strains of friendly bacteria has been shown to help maintain the health of the intestinal tract and aid digestion, reduced bloating and the establishment of a regular bowel habits.

A change of food may upset a sensitive tummy

Our immune system is used to dealing with bacterial or viral challenges on a regular basis, but when we travel we can encounter different or possibly more pathogenic strains that then cause us to become ill. A change of food may also upset a sensitive tummy, as well as traveller’s diarrhoea people may also suffer from bloating or discomfort. You can reduce your chances of falling ill by giving your immune system and gut flora extra support by taking a probiotic supplement before jetting off to exotic destinations. Closer to home evidence continues to grow that probiotic supplements are a key element in the management of IBS, a combination of L.plantarum and L.acidophilus has been found to be especially effective.

Choosing a probiotic supplement

The effectiveness of probiotics is linked to their ability to survive the transit from stomach to small intestine; to do so they must be able to resist both acidic and alkaline conditions.

To confer health benefits probiotic supplements must contain live bacteria capable of adhering to the intestinal lining and colonise in the colon. Always choose products by trusted and established manufacturers.

Lyophilised (freeze dried) bacteria are stable at room temperature so do not need refrigeration.

Look for a delayed release product, delaying the release of the bacteria until they reach the small intestine protects them against the acidic environment of the stomach and delivering them directly where they are needed.

Probiotic Lactobacilus rhamnosus aids weight loss in overweight women

A study published recently in the British Journal of Nutrition has found that supplementation with the probiotic L. rhamnosus encourages weight loss in overweight women.

Weight Loss
A probiotic supplement may encourage weight loss and healthy metabolic changes when used alongside a healthy, balanced diet.

A group of 125 overweight men and women were placed on a calorie restricted diet for 12 weeks, followed by a further 12-weeks of a ‘weight maintenance’ diet. While half of the participants were given a placebo supplement, the other half were given two capsules of L rhamnosus probiotic supplements at a total daily dosage of 1.6 billion L rhamnosus bacteria.

Both body weight and body composition were measured at the beginning of the study and then at 12 and 24 weeks. The probiotic supplement did not appear to affect weight loss in the men at all. However, the effect of probiotics on the women in the study was more marked. Compared to the women in the placebo group, those women taking probiotics experienced significantly more weight loss at the 12-week mark. While the placebo group managed a loss of 2.6 kg, those women on probiotics experienced an average loss of 4.4 kg.

After 12 weeks, all of the women were placed on a weight maintenance diet. As expected, the women in the placebo group maintained their original weight loss. In contrast, the women in the probiotic group continued to lose weight and body fat, losing an average of 5.2 kg by the end of the study. These women were also found to have lower levels of circulating leptin, a hormone that helps to regulate appetite and satiety.

It is particularly interesting that the women taking the probiotic continued to lose weight despite eating at maintenance. The study’s results suggest that the L. rhamnosus strain may encourage metabolic changes that favour weight loss. The researchers suggest that probiotics may act by altering the permeability of the intestinal wall. Because probiotics can prevent certain proinflammatory molecules from entering the bloodstream, they might therefore help prevent the chain reaction that leads to glucose intolerance, type 2 diabetes, and obesity. This mechanism of action suggest that other strains of probiotics could have a similar effect. Indeed other studies have encountered similar successful results with probiotics such as lactobacillus fermentum, lactobacillus amylovorus, akkermansia muciniphila and lactobacillus gasserei (2-4).

It is not clear why the rhamnosus probiotic appeared to benefit the women but not the men in the study. The researchers suggested that the men may have needed a higher dose or a longer period of supplementation.

Clearly maintaining a healthy weight requires a healthy, balanced diet. For those wanting to lose weight, this study suggests that a probiotic supplement may encourage weight loss and healthy metabolic changes when used alongside a healthy, balanced diet. The link between probiotics and weight loss is a particularly fascinating one, and hopefully this study will encourage further research in this area.

  • Help others. There is no better pick-you-up than helping others. Volunteer, be a good listener or write letters to friends to bring them cheer.
  • It can be hard to keep your spirits up in the dark winter months, try some extra vitamin D. Vitamin D has been the subject of a wealth of research studies and has been shown to contribute to the normal function of the immune system as well as essential in the health of bones, muscles and teeth. Sometimes called the Sunshine Vitamin, we often miss it most in the winter months.

Beat the winter bugs with beneficial bacteria

As the weather worsens and the season of colds and coughs approaches, our thoughts turn towards ways in which we can support our immune systems to help keep us fighting fit throughout the winter.

A current theory in medicine, known as the ‘Hygiene Hypothesis’, states that our obsession with household cleaners and overzealous hand washing with anti-bacterial agents may be to blame for a rise in infections, as well as conditions such as asthma.

Our immune system is designed to fight infection from bacteria, viruses and parasites as well as recognise foreign substances as allergens. As our bodies no longer need to fight germs as much as they did in the past, we no longer have to elicit an immune response. The theory indicates that bacteria can in fact be helpful for supporting our immune systems.

So, how can we use bacteria to help boost our immunity? Health experts suggest we should allow children to be children by letting them play outside in mud and with their friends, and worrying less about them coming into contact with dirt and germs. There is also an increasing body of evidence supporting the use of probiotics (beneficial bacteria) for immune support. Our digestive tract functions as a barrier against potentially harmful bacteria and food. It is known that supplementing with probiotics can help mediate our immune response, reducing inflammation and protecting us against exposure to potentially harmful bugs.
