    Billion Count

    It is not always necessary to take very high doses of probiotic bacteria – in some cases a strain can be sufficient at doses of just 1 billion CFU – however, if you want to take a high strength probiotic supplement, then we recommend choosing one containing some of the best, most researched strains in the world.

    Some people do very well on a more powerful probiotic supplement, but research shows that it is still more important to look at the quality of the bacterial strains, before you look at the number of billions. The best probiotic supplements are transparent and always list the strains of bacteria, not just the species, because each strain has unique properties. This allows you to look at the research that supports each strain and enables you to choose the strains which have been researched for the health conditions you wish to support so are most suited to your needs.

  • How To Use

    Recommended use

    Customer Questions

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

    Can a probiotic be too high strength?

    Probiotics are very safe supplements, and it’s not thought to be possible to ‘overdose’ on them: the human gut naturally contains trillions of micro-organisms, so the number of bacteria in a supplement is relatively small by comparison, and clinical trials have used doses up to 500 billion1. However, we’re all different with a unique gut microbiome, and some people do better on higher strength supplements, whereas others find they get the support they need from a lower dose. If you want to try a more powerful supplement but tend to be sensitive to new foods and supplements, then it’s best to start with a low dose and gradually increase. You can open all Optibac capsules and take half a dose if preferred.

    How do I choose the best probiotic for adults?

    With so many brands to choose from, it can be difficult to choose the probiotic supplement that’s right for you. We recommend looking for a probiotic which is guaranteed to reach the gut alive, contains well-researched strains, is shelf stable and does not need refrigerating. It is always good to choose a product with great customer reviews, but most importantly it should contain strains researched for the condition you’re trying to support.

    Is it OK to take a probiotic every day?

    Yes, it is safe and generally advisable to take your probiotic supplement daily. Probiotics colonize in the gut for a few weeks but research,2,4,5 suggests that the probiotic strains – along with their positive benefits – will disappear without regular supplementation, so it is a good idea to regularly support your microbiome. You can do this by including prebiotic-rich and fermented foods in your diet, but it is worth remembering that not all probiotics do the same thing in the body. Therefore, if you have a specific health condition you need to support, it is best to consume specific strains which have been shown to be helpful for your individual needs.

    Should you take probiotics on a full or empty stomach?

    In general, it’s best to take probiotics with the first meal of the day. There are concerns that stomach acid will damage the delicate probiotic bacteria, and that taking them on an empty stomach will help. But at breakfast time, stomach acidity is closer to ‘neutral’ than at other times of day (i.e. least acidic), and there is a lag time (up to 30 minutes) between food consumption and stomach acid release. Taking probiotics 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 probiotics 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, for menstrual bloating, or during the winter flu season. However, if you have ongoing health conditions, or just want to give your gut or vaginal microbiome a daily boost of good bacteria, then take your supplements every day. There is no current research to suggest the body becomes dependent on probiotics, so if you just feel better when you take them, it is fine to take your probiotics on a long-term, ongoing basis.

    • I would highly recommend this excellent product which cleared up a chronic condition where other brands of probiotics and treatments did not. Brilliant, easy and worth every penny.

      Rosie Sprake - 9th March 2021

    • I have been taking this product for 2 weeks. I have IBS constipation, spasms and surprisingly 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 for Crohn's after a colonoscopy 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!
