CFU stands for Colony Forming Unit . It’s the number of bacterial colonies that form on a Petri dish and indicates a product’s viability or strength. Your intestinal tract contains over 1OO trillion microorganisms from about 1,000 different species, mostly bacteria. Only high potency probiotic products (those containing 10 billion CFU/capsule or more) can reliably re-establish the probiotic population within this huge number.
