Research & Development

ProVen Probiotics parent company has been manufacturing probiotics products for more than 30 years
Well before the launch of the ProVen brand, which has built upon this experience to develop products designed for individual needs and lifestages.

Excellence in Probiotics

Research is at the heart of ProVen Probiotics culture. The company has its own research laboratories and employs a large team of research scientists, who have published more than 100 peer-reviewed publications supporting the health benefits of the ProVen products.

The ProVen range contains our own proprietary probiotics consortia – Lab4, Lab4B and Lab4P – which have the widest range of clinically proven benefits of any probiotics blends in the world.

Research to date has studied the efficacy of the Lab4 probiotics blends for irritable bowel syndrome (IBS) and other digestive issues, immunity, weight loss, athletic performance, mood, allergy, safety and for use alongside antibiotics.

Our goal is excellence across all aspects of probiotics product development, to ensure the quality, safety and efficacy of all ProVen Probiotics at all times.

The Lab4 Probiotics Consortia

Lab4 probiotics is the most clinically-studied probiotics consortium in the UK and has the widest range of proven benefits of any blend of probiotics in the world.
Lab4 probiotics were isolated and developed by Dr Nigel Plummer and his team of scientists and contain both Lactobacilli and Bifidobacteria strains found naturally in the human gastrointestinal tract. These strains were selected based upon their ability to survive stomach and bile acids, attachment and antimicrobial properties, and viability and growth profiles. The Lab4 consortium has been subject to research and customer feedback for more than 20 years and forms the basis of the ProVen Probiotics product range.

Lactobacillus acidophilus - CUL21
Bifidobacterium bifidum - CUL20
Bifidobacterium animalis subsp. lactis - CUL34

The Lab4 probiotics consortium was identified more than 20 years ago and has since been subject to more than 15 clinical trials underpinning the effectiveness of this multi-strain probiotics blend in supporting health in general and for a wide variety of health issues.  We now have two further Lab4 blends – Lab4B and Lab4P – which have also been shown in clinical trials to be effective in relation to specific health issues and lifestages.

Lactobacillus salivarius - CUL61
Lactobacillus paracasei - CUL08
Bifidobacterium bifidum - CUL20
Bifidobacterium animalis subsp. lactis - CUL34

Lab4B is a blend of four bacteria strains naturally present in the infant gut, which has been shown to be completely safe for use during pregnancy and with new-born infants and to reduce the development of eczema and allergy during the first years of life.

Bifidobacterium bifidum - CUL21
Bifidobacterium animalis subsp. lactis - CUL34

Lab4P contains five strains of bacteria – the four Lab4 strains with Lactobacillus plantarum – and has been shown to support weight loss and to provide benefits in relation to immunity and overall quality of life.
