About Count the CFU

These guides are written for curious adults who pick up a probiotic bottle, see a long number followed by CFU, and want to know what it actually tells them. No background in microbiology is needed.

We cover the definition of colony-forming units, how to read large counts, the difference between counts at manufacture and at expiry, why per-strain amounts matter, and what a label should say about storage. ProDentim is used as the example product, and only as what the seller or the label states.

The aim is to help readers make sense of everyday oral health topics so they can ask better questions of sellers and of their dental team. The site is an independent guide, not a clinic, and nothing here is medical advice.
