WebCFUs, or “colony forming units,” are a unit of measurement used to determine the number of live bacterial cells in a probiotic supplement or lab sample. In other words, along with other factors, a CFU count can give us some insight into the quality of a probiotic.*. Read on for a deep dive into colony forming units—what they are, what ...
