Probiotics
With meals
Probiotics are live beneficial microorganisms, primarily bacteria and yeasts, that support health when consumed in sufficient quantities. Found naturally in fermented foods like yogurt, kefir, and sauerkraut, they are also available as concentrated supplements containing specific bacterial strains. Different strains serve distinct functions, making strain selection important for targeted health goals.
