At OptiBac, we specialise entirely in friendly bacteria and we offer specific strains for your individual needs. We're proud to be the UK & Ireland's most trusted brand** and if you're new to friendly bacteria supplements, here's why you can trust us too.

Especially for you

We've always been at the forefront of using specific strains for individual needs. This is important because research shows that different types of friendly bacteria have different properties. Unlike most other live cultures out there, we appreciate that it's not a question of one-size-fits-all, and we tailor our wide range accordingly. We have options for the entire family, from those especially for babies to every day friendly bacteria supplements. We also have supplements for different life stages such as 'For pregnancy' or 'For your cholesterol'. Make sure you choose the right friendly bacteria for you.
