Short answer
It means USP checked that a supplement's contents match its label for purity and potency. Mark Hyman lists USP with NSF and ConsumerLab as marks to seek, and Rhonda Patrick names USP verification when choosing probiotics. The seal matters because many supplement labels don't match what is in the product.
positive partly neutral negative Each researcher and each study counts once per claim, however often they come up.

USP verification shows that a supplement's contents match its label for purity and potency. USP stands for U.S. Pharmacopeia, one of the independent standards bodies named when supplement quality comes up. A USP mark says a third party checked what is in the bottle against the label.
Mark Hyman lists three marks to look for: NSF International, USP and ConsumerLab, which screen out poor-quality products. Rhonda Patrick names USP verification when picking a probiotic, as a sign the product is still alive. Probiotics sit in an unregulated category with unreliable labels, so an outside mark is one of the few quality signals a buyer gets.
Andrew Huberman explains that many products don't match their labels, so buyers should favor independently validated brands. Potency can stray far from the label, and for melatonin it can reach toxic levels. A USP-type check exists to close that gap.
USP is named as a reputable third-party mark, but no source walks through the criteria of the formal USP Verified program. Treat it as a mark worth looking for, without assuming anyone has audited its internal standards for you.
