Best Probiotic Supplements – UK Buyers Guide

Best Probiotic Supplements UK

Recent studies have reported that an imbalance of gut flora has been linked by researchers to several chronic diseases including eczema, rheumatoid arthritis and inflammatory bowel or irritable bowel diseases. In fact, gut health and how to influence the operation of the gut are now major health trends that are sweeping the UK market, and many manufacturers are scrambling to provide supplements that are beneficial to overall gut health.


The reason experts are researching gut health is quite simple. The microflora that lines the gut acts like a separate organ and plays a vital role in maintaining the health of its host. Some researchers suggest that upwards of 80 per cent of your immune system is located in your gut, so if your gut is suffering, there is a very strong chance it is going to affect your general health. And this is where probiotics come into play, and specifically probiotic supplements.

Probiotics have been shown to be effective in treating gut flora imbalance. When ingested, these living micro-organisms replenish the microflora in your intestinal tract.


The replenishment of microflora in your intestinal tract results in the promotion of several health-enhancing functions, including enhanced digestive support. So if these microflora are so beneficial for you health, why are we all scrambling to take some so that our overall health is improved. Well, the problem for consumers is that there is also growing evidence that only particular strains of probiotics are effective for certain conditions.


Not all probiotics are suitable for all conditions, and some experts even suggest that some of the probiotic products for sale on the market today may have some great marketing and PR, but actually will have little to no health benefits.
There are some things in a probiotic or probiotic supplement that you definitely need to look for:

  • Gastric acid and bile-salt stability
  • An ability to adhere to intestinal mucus
  • An ability to colonise in the gastrointestinal tract


For most of the commercially available probiotic supplements and yogurts on the market today, the products themselves actually do exhibit some or all of these characteristics, but some of the products don’t, and that is why our intrepid team have reviewed some of the best probiotic supplements on the  UK market today, to ensure you are getting the best product that will assist with your health needs.


If a probiotic strain does not exhibit these characteristics, then it will be nowhere near as effective as those that do

Probiotic bacteria has been shown to help restore healthy stomach bacteria and is recommended by doctors and naturopaths to help in the treatment and prevention of eczema, irritable bowel syndrome (IBS) and other conditions.


Because there are many helpful bacterial strains, you need to choose the best probiotic strains to suit your health. We all know probiotics are good for us, and this is even now backed up by some scientific research that show that while everyone benefits from a varied diet that contains probiotic foods (including sauerkraut and yoghurt), a probiotic supplement is best used for a specific health issue. But many of us don’t know what the best probiotic supplement for each condition is, and it imperative that you are very clear as to why you’re supplementing and whether you are supplementing with the right strain.


Another important factor to consider is your age, as our gut microbiome changes from infancy to old age. So you need to ensure that you are supplementing with the products that include bacterial strains that support a specific life-stage related function. Here’s our general tips on wha to look for related to some overall life stages:

Babies and Kids

For digestion: Bifidobacterium lactis and Streptococcus thermophilus help reduce the incidence of diarrhoea and the severity of colic in babies. Recent studies have found that Lactobacillus rhamnosus and Saccharomyces boulardii are both helpful in preventing AAD. These strains are also good for reducing the duration of stomach viruses. 


For Irritable Bowel Syndrome (IBS): Bifidobacterium infantis 35624 has the most research behind it, showing it improves abdominal pain and bloating in sufferers of IBS.

Vaginal health: Studies indicate that certain strains of Lactobacillus (acidophilus, rhamnosus GR-1 and reuteri RC-14) may help treat bacterial vaginosis (an infection).

After antibiotics: The same probiotics that help prevent AAD in kids – Lactobacillus rhamnosus and Saccharomyces boulardii – help adults repatriate their gut flora.


For constipation and bowel health: Bifidobacterium lactis and Bifidobacterium longum strains can improve bowel movements and soften stools. Bifidobacterium levels decline in older populations.

There is a heap of new research emerging revealing that probiotics — the so called “good” bacteria in the human gut — are packing a serious punch in the fight against illness and some diseases. Each person carries about in their gut trillions of beneficial bacteria every day, making up what is commonly called the body’s “gut flora”. It is the good bacteria’s job to fight off “bad” bacteria in the form of illness and other hazards to the body. But when the gut flora is compromised by sickness, antibiotic medicines or poor eating habits, for example, a person’s health may be compromised.


So research is now taking place at a rapid rate to identify which bacteria and what quantities are needed to help prevent and treat disease. Chat to any nutritionist and they will advise you that taking a probiotic each day will not only replenish the levels of good bacteria in the human body but will also rally the gut flora into attack mode when bad bacteria enters the body.


In fact, probiotics are known around the world as bacteria with benefits. Recent studies have shown that probiotics can:

  1. Help reduce the incidence of eczema in babies

    Probiotics could help reduce the incidence of eczema in babies whose mothers took probiotics during pregnancy or during breastfeeding

  2. Resolve cases of diarrhoea

    Helps resolve or reduce cases of diarrhoea in both children and adults, and improve bowel movements

  3. Reduce the risk of allergies and asthma.

  4. Restore gut health

    Help to restore gut health after a course of antibiotics

  5. Improve child well being

    Reduce the number of days children in day care are ill with fevers, coughs and colds

  6. Improve production of isoflavones

    May help to encourage the production of antioxidant-rich isoflavones in men which are known to fight prostate cancer cells

There is no doubt that probiotics are well recognised for improving immune function. But you need to ensure that you are taking the right probiotic supplements for your specific needs. So what exactly are the best probiotic supplements ?
