If you're new to the world of friendly bacteria, also known as live cultures*, it can be very confusing. In simple terms, we all play host to trillions of tiny micro-organisms, most of which reside in our gut. Some of these are friendly towards their host, and some are not. It's normal to have a mix of good and bad bacteria in the gut microbiome, but an ideal balance is to have more good than bad. Modern living can affect this delicate balance, which is why many people take friendly bacteria supplements containing good bacteria to help complement the natural gut microbiome. If you would like to find out more about good bacteria, head over to the Probiotics Learning Lab.
Yes! It is both safe and recommended to take your friendly bacteria supplement on a daily, ongoing basis. Research7,8,9 suggests that good bacteria only colonise in the gut for a few weeks, so it's a good idea to have a regular intake of friendly bacteria.
It's absolutely fine to open Optibac friendly bacteria capsules and take the contents directly into the mouth or in cool, non-acidic food/drink, without any effect on the viability of the friendly bacteria. Encapsulated friendly bacteria from other brands may need to remain in their capsules, however, so best check with the manufacturer.
Optibac have a range of supplements with added vitamins and minerals for both adults and children. You can choose products with added Vitamin C, Vitamin D, Calcium, or Zinc. For more information, visit our Added Nutrients section.

*Friendly bacteria, also known as ‘live cultures’ or ‘probiotics’, are good bacteria which live in the gut and are considered to be vital for good digestive and overall health2,3. We must refer to probiotics as 'live cultures' or 'friendly bacteria' throughout our website due to European legislation guidance.
