Is Creatine legal in the United States?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
Creatine can be sold in the United States as a supplement or cosmetic ingredient, classified as "Sold as a dietary supplement". That is not drug approval: FDA has not evaluated any health claim, and injectable or "research use only" versions fall outside supplement rules, so that label does not make human use lawful. On the evidence, 2 human studies are cited on its profile.

What Creatine is
The most studied supplement there is, with a solid strength effect, a smaller hypertrophy effect than marketing implies, and a cognition claim a regulator has formally rejected.
Creatine is a compound your body makes and you also eat in meat, stored in muscle as phosphocreatine and used to regenerate ATP during short intense efforts. Its effect on strength and work capacity is real and about as well established as anything in this catalogue.
Mechanism: Loads muscle phosphocreatine, which regenerates ATP from ADP during high intensity work lasting seconds. That raises work capacity per session, and the extra work done over months is the likely route to most of the strength gain rather than any direct anabolic action.
Regulatory history: Sold as a dietary supplement. Not an approved drug for any indication.
How FDA treats this kind of product
Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.
The classification above is the The Longevity Archive reading of U.S. Food and Drug Administration listings for Creatine at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
