Why Choose ProVen Probiotics?

Not all friendly bacteria are equal. When choosing your friendly bacteria supplement, always look for the following 12 criteria as a start point and then select the best product(s) to suit you and your family.

Why Choose ProVen

Human strains

The strains used in ProVen Probiotics were originally isolated from the gut microbiota of healthy humans and screened for appropriate characteristics and safety. They are naturally present in our intestines, but their numbers can be reduced due to stresses of our modern lifestyle.

Why Choose ProVen


The human gut contains thousands of different strains of live bacteria (from different groups and species) and multi-strain products have been shown to work synergistically to support this diversity.

The Lactobacillus and Bifidobacteria groups (genera) of probiotic bacteria are the most studied and ProVen Probiotics contain two strains of each group and additional Lactobacillus strains when suited to a particular product.

Why Choose ProVen

Clearly defined strain numbers

ProVen Probiotics products contain the Lab4 and Lab4b consortia of bacteria, which contain the following strains – the strain numbers are clearly labelled in brackets.

Lab4 – Lactobacillus acidophilus CUL60, Lactobacillus acidophilus (CUL21), Bifidobacterium bifidum (CUL20), Bifidobacterium animalis subsp. lactis (CUL34)

Lab4b – Lactobacillus salivarius (CUL61), Lactobacillus paracasei (CUL08), Bifidobacterium bifidum (CUL20), Bifidobacterium animalis subsp. lactis (CUL34)

Why Choose ProVen

Evidence that the bacteria survive stomach and bile acids

The stomach is an acidic environment and friendly bacteria need to be able to survive this to reach the microbiota in the intestines. ProVen Probiotics are held in suspension in their various formats until they reach the stomach. Taking them with food will ensure that the pH of the stomach allows them to pass into the small intestine alongside the food as it is digested.

Why Choose ProVen


Safety is a key consideration when choosing any supplement.

As well as having a vast number of ongoing customers of ProVen products (including children, babies and pensioners), ProVen Probiotics are continuously being scrutinised in research studies and were specifically approved for use in a trial with pregnant mums and their newborn babies and shown to be completely safe for use by these vulnerable groups.

Why Choose ProVen

Commitment to research

ProVen Probiotics and the Lab4 bacteria that they contain are supported by a strong body of research published in peer-reviewed journals and we are involved in a continuous research programme to support the efficacy of the products we sell.

How are ProVen Probiotics Different?

ProVen Probiotics contain the unique Lab4 probiotic strains. This group of strains is one of the very few probiotic cultures that have been rigourously studied over the past 15 years to demonstrate consistent health benefits ranging from allergy prevention in infants to reduction of all symptoms (bloating, pain, discomfort) in people suffering from Irritable Bowel Syndrome (IBS).

Other studies conducted at Addenbrooke’s hospital in Cambridge have shown that Lab4 can reduce the levels of ‘bad bacteria’ following antibiotic treatment, as well as reducing the incidence of diarrhoea caused by the ‘superbug’ Clostridium difficile.

ProVen Probiotics have also been developed based upon 30 years of research and development in probiotic bacteria and products. As well as the Lab4 bacteria, the team of scientists behind ProVen Probiotics have identified a process to add other nutrients, such as vitamins and immune enhancing ingredients such as elderberry, to the supplements without destabilising the Lab4 bacteria.

As a result, ProVen Probiotics offers a range of products that include continuously researched live bacteria and key nutrients to support health.

Can you take too much friendly bacteria?

No, it is virtually impossible to overdose on probiotics. We all have billions (some estimates say trillions) of ‘friendly’ bacteria in our body and these are constantly being replaced. ProVen Probiotics containing Lab4 strains of friendly bacteria can help this replacement process and support a balanced microflora. Taking very large amounts may mildly increase frequency of bowel movement.

How can I identify a good probiotic supplement?

The European Consensus, taken in 2004, outlines a number of criteria to help people distinguish good quality probiotics as follows:

  • Have clinically proven health benefits demonstrated using rigorous scientific trials (randomised, double blind, and placebo controlled designed trials).
  • Are alive and reach the gut in sufficient number, surviving gastric and bile acid and digestive enzymes during the gastro-intestinal transit until they reach the gut.
  • Are clearly defined using modern biological detection methods.
  • Are clearly labeled, including the genus (eg. Lactobacillus), the strain e.g acidophilus Cul -21) and amount e.g 10 billion.
  • Are shelf stable, thus guaranteeing delivery of the quantity of probiotic until the date of expiry.

ProVen Probiotics containing Lab4 probiotic strains satisfy all these criteria.

Are ProVen Probiotics natural?

Yes, the friendly bacteria used in all ProVen Probiotics products are naturally sourced and cultured.
