Customer Questions

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

A max strength friendly bacteria supplement typically contains at least 50 billion live cultures. It's not always necessary to take max strength supplements, as in some cases a strain maybe sufficient at doses of just 1 billion live cultures(1)! But some people find they do better when taking max strength supplement. If this is the case, still look at the strains before looking at the number of billions (high-quality supplements always list the strains not just the species). It's best to take high-quality strains which have been researched for your individual needs. Optibac Every Day MAX contains 75 billion live cultures of the highest quality, extensively researched friendly bacteria, including one of the world’s most researched strains, Lactobacillus acidophilus NCFM®.

Many people like to take specific friendly bacteria strains at certain times, for example during pregnancy, with and after antibiotics, or during the winter flu season. However, many people feel better when taking max strength live cultures every day, to complement their natural gut bacteria. Research (1,2) suggests that ongoing daily use is fine, with no risk of dependency.

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

Many people are unsure what time they should take friendly bacteria supplements, or if they should take live cultures with or without food, especially when taking max strength supplements. In general, it’s best to take your friendly bacteria at breakfast time, as this is when stomach acidity is closer to neutral. Taking live cultures with food further helps to buffer the acid and help the live cultures into the gut. If you miss breakfast, just take with another meal or snack.
