  • I genuinely feel my stomach is more settled after about 2 weeks. I’m guessing if my gut feels fine something is right which will lead to better health.

    Andy C- 17th April 2022

  • A huge thank you to OptiBac Advisor and Nutritionist Claire Foss for all her support and guidance around my digestive health and OptiBac products. Very happy to say that the gentleness of OptiBac is working well after a few weeks after many other brands did not agree my digestive system. The secret is trying different products, give them a few weeks each. I know you're eager to reduce your symptoms, but issues like this can take some time to resolve... keep going, and thanks again to Claire for her help.

    Joe- 25th May 2021

  • My wife bought this for us last year and we've both been taking it ever since. So far so good - we're feeling well, good energy and regular in the gut health department!

Yes! It’s not possible to overdose on live cultures supplements as your gut naturally contains trillions of friendly bacteria. Friendly bacteria have been researched for decades, and daily use is both safe and recommended, without risk of dependency or overdose (1,2,3).
