Yes! It is both safe and recommended to take your friendly bacteria supplement on a daily, ongoing basis. Research4,5,6 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 live cultures.
It's absolutely fine to open Optibac live cultures 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 live cultures from other brands may need to remain in their capsules, however, so best check with the manufacturer.
We certainly do! 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, Vitamin B1, Calcium, and Zinc. For more information, visit our Added Nutrients section.
