Friendly bacteria: your questions answered

Should I take friendly bacteria every day?

Yes, it is perfectly safe and generally advisable to take a friendly bacteria supplement every day. Good bacteria only colonise in the gut for a few weeks and research(1,2,3) suggests that taking regular digestive supplements helps to complement the gut microbiome.

What is the difference between gummies vs capsules or powder?

Friendly bacteria supplements in capsules or powder form typically contain Lactobacilli or Bifidobacteria, whereas gut gummies use heat-resistant friendly bacteria like Bacillus coagulans Unique IS-2 (4,5). People often wonder if gummies are as good as capsules or powders, because they taste like yummy ‘sweets’,  but rest assured, if you buy from a trusted company, you can be sure the friendly bacteria strains and ingredients are of the highest quality.

What strength of live cultures is best?

With live cultures, ‘more’ is not always ‘better’, though some people do better on high-strength friendly bacteria supplements. It is still important to choose high strength supplements with highly researched strains featured in multiple gold standard clinical trials, where the research is relevant to your needs. High strength supplements like Optibac Every Day EXTRA (6) contain the same number of billions used in supporting clinical trials.
