For health professionals, impartially curated by OptiBac
We've been working on something very special over the last few months, which will be of particular interest to CAM & Health Care practitioners. It's an impartial educational tool called the 'Probiotics Database' which aims to detail some of the world's most researched probiotic strains, and the respective research undertaken on each.

Impartial and Balanced

We've included some of the most well-researched strains in the world, as we want to give you a balanced, non-commercial resource which you can trust and use with your clients and patients.

Learn about some of the world's most researched strains on the Probiotics Database

How it works

You will learn about how probiotic (head over to the Probiotics Learning Lab for more glossary terms) strains are classified and how they are related to each other, as well as how each strain has been researched, and in what areas of health they've been found to be helpful. One of the first things on the database you'll see are the taxonomic trees. For example:

The current line-up in our Lactobacilli taxonomic tree
What you can see above is the taxonomic classification, or "family tree", of the Lactobacillus genus. Our current line-up details 5 key species and some of the strains that belong to each of them. All probiotics should be classified using genus, species and strain, as research shows that the health benefits of probiotics are strain specific. For example, one strain of L. rhamnosus may be good for vaginal health, but another may be more helpful in helping to prevent antibiotic-associated diarrhoea.

On the front page of the database you'll also be able to use the conditions filter to see which strains have been researched for specific health conditions. For example, if you wish to see what probiotic strains have been most researched for IBS, you can select that condition and your results will appear on the family trees below.

Human clinical trials

On each strain page you'll be able to read about clinical trials that have been undertaken on that specific strain. The research we have documented on the database only includes human clinical trials, we do not detail in-vitro tests on the database as these are not significant in showing the benefits of probiotics in human health. We only detail clinical trials as these are considered the gold standard in research.

We hope that the Probiotics Database will be a really useful educational resource for CAM and healthcare practitioners, and we hope that it gives you more confidence when considering probiotics with your clients.
