    Billion Count

    Research shows that it is more important to look at the quality of the bacterial strains, before you look at the number of billions. The best live cultures supplements always list the strains of bacteria i.e. Lactobacillus acidophilus NCFM® and not just the species (Lactobacillus acidophilus) because no strain is the same.

    Listing a strain shows transparency. It allows to identify whether there is any research on the strain, what the quality of that research is and what potential benefits the strain may offer. It's best to take the product with the most researched, high quality strains, which are most suited to your needs. Whilst it's not always necessary to take very high doses of friendly bacteria, as in some cases a strain can be sufficient at doses of just 1 billion CFU - if you are going to take a high strength live cultures supplement, then we recommend choosing one containing some of the most researched strains in the world.

    Customer Questions

    All questions answered by probiotic experts Dr Kate Stephens PhD (Food and Microbial Sciences) BSc(Hons) Medical Microbiology Kerry Beeson BSc (Nut. Med.) Nutritional Therapist.

    Is it OK to take live cultures every day?

    Yes, it is safe and generally advisable to take live cultures daily. Good bacteria colonise in the gut for a few weeks but research1,2,3 suggests that the good bacteria strains will disappear without regular supplementation, so for this reason you might wish to take them regularly.

    Should you take friendly bacteria on a full or empty stomach?

    In general, it’s best to take friendly bacteria with the first meal of the day. There are concerns that stomach acid will damage delicate live cultures bacteria, and that taking them on an empty stomach will help. But at breakfast time, stomach acidity is at its most neutral, and there is a lag time (up to 30 minutes) between food consumption and stomach acid release. Taking friendly bacteria with food has additional benefits: the food helps to buffer the effects of stomach acid, facilitate the passage of the probiotics through the stomach, and ensures that they are well mixed with the stomach contents as they pass into the small intestines.

    How long should you take live cultures for?

    This depends on why you are taking them: some people like to take specific strains at certain times, for example during pregnancy, when travelling abroad, or during the winter flu season. However, as mentioned above, many people prefer to take live cultures on an ongoing basis. There is no current research to suggest the body becomes dependent on good bacteria, so long-term supplementation is fine.

    • I would highly recommend this excellent product. Brilliant, easy and worth every penny.

      Rosie Sprake - 9th March 2021

    • I have been taking this product for 2 weeks. I feel much better. Of course with a proper diet. I would like to ask if it can be taken for a long time. What other products might be useful?

      Aurora - 25th November 2020

    • Reached out to OptiBac for advice on which probiotic to take in order to support and repopulate the gut. Beverley, an OptiBac nutritional advisor, couldn't have been more helpful and sent over an extremely comprehensive, informative and personalised email. I ended up purchasing this 'Everyday Max' product alongside S. boulardii which work in complementary fashion to each other, and both have been brilliant. Could not recommend highly enough. Thank you!
