About us
Probiotic Supplements UK is a small team in Newcastle upon Tyne writing plain-English guides for people who want to understand probiotic supplements before they buy. We do not sell, make or rank supplements, so everything here is written to help you compare products for yourself.

Who we are
We are a small team based in Newcastle upon Tyne who write about probiotic supplements for UK shoppers. Our guides answer the questions people tend to have when comparing probiotics, such as what the strain names mean, whether a bigger CFU number is worth paying for and why the pack says so little about what the product does.
Everything we publish is free to read. The guides cover probiotic types, strains, CFU counts, labels, storage and quality, and they are written for adults buying for themselves. Anyone buying for a child or managing a health condition should also speak to a pharmacist or GP.
Probiotic supplements are hard to compare. Two products can list the same species but different strains, state their counts at different points in their shelf life and use packaging that protects the cultures to very different degrees. A guide that also sells or promotes products has a reason to blur those differences, so we have chosen not to sell, endorse or rank anything.
We do not name brands or products in our guides, and we do not publish star ratings, reviews or lists of top picks. Instead we explain the features that separate one product from another, so you can apply the same checks to any pack you pick up. Our guide on how to choose a probiotic supplement puts those checks in order.
No health claims are currently authorised for probiotics in Great Britain, and research on one strain does not automatically apply to another. We describe what research covers in careful, general terms and never present a product as a remedy for any health condition. Where a claim on a pack refers to an added vitamin or mineral, we point out that it relates to the nutrient rather than the cultures, as our guide to reading a probiotic label explains.
Our approach
Every guide follows the same process, from the first question to later revisions.
Each guide begins with something shoppers ask, such as what CFU means or how to store a probiotic after opening, and answers it directly.
We draw on published research and official UK guidance on food supplements, and we describe them in general terms rather than quoting single results.
Findings about one strain are never stretched to a whole species, for the reasons set out in our strains guide. Nothing on the site is presented as a way to manage a health condition.
Guides are updated when labelling guidance changes, when strain names are revised or when a reader points out something that is unclear.
Being clear about our limits is part of staying independent.
