Probiotics: CFU and strains per serving on every probiotic label we carry

CFU (colony-forming units) is the headline number on a probiotic, from 1 billion to 100 billion per serving, but more isn't automatically better — strains and whether the count is guaranteed through expiry (not 'at time of manufacture') matter as much. The table lists the printed CFU and strain count for every probiotic we track.

Questions people ask

How many CFU should a probiotic have?

Labels we track range from 1 billion (a single-strain daily) to 60+ billion (multi-strain formulas). There's no single right number; pick by the strains and the 'through expiry' guarantee, then the count.

Do probiotics need to be refrigerated?

Some do, some are shelf-stable — the label and the pharmacy shelf tell you. Shelf-stable products often print the CFU count guaranteed at expiry.
