What does CFU mean in probiotic supplements?Updated 5 months ago

CFU stands for colony-forming unit, which is a measure of viable bacteria in a probiotic supplement. These are the bacteria capable of surviving and thriving in your digestive system. For instance, if a probiotic supplement contains 10 billion CFU per capsule, this means that 10 billion live friendly bacteria are expected to reach your gut alive, where they can begin to support your health.
