Why Trust Us?

Guaranteed bacteria count to expiry

The TriPhase and StabilityMax technology used to manufacture ProVen Probiotics products, guarantees the stated number of live bacteria to the expiry date of the product. We utilise 'gas-tight' packaging and 'overage' of bacteria to ensure this.

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.

Free from artificial colours, flavours and preservatives

None of the ProVen Probiotics products contain artificial colours, flavours or preservatives. Full details of the ingredients for each product can be found on the product info page.

GMO free

Our manufacturing facility is 100% free of genetically modified organisms. We do not handle genetically modified ingredients and will never include them in our products.

Survival at room temperature

As an expert manufacturer of friendly bacteria, ProVen Probiotics are able to ensure that high potency products are stable for 18-24 months in room temperature conditions. Our manufacturing processes are optimised to increase stability of the bacteria at every stage.

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.

Positive, independent reviews

ProVen Probiotics is part of Feefo, an independent and therefore unbiased review service, and all our online customers are asked by Feefo to provide honest feedback about our products and the experience they had when purchasing from us.

Manufactured to cGMP standards

ProVen Probiotics are manufactured to current Good Manufacturing Practices (GMP) and accredited by the MHRA (Medicines & Healthcare Products Regulatory Agency). GMP provide requirements that a manufacturer must meet to ensure products are consistently high in quality.


The human gut contains thousands of different strains of live bacteria 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.

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.

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)


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.
