Dietitian Licensure in California: Title Protection, Not a License

California does not license or register dietitians — there is no state board, no application, and no renewal process. State law (Business and Professions Code Chapter 5.65, §2585) instead makes it a misdemeanor for anyone to use the titles "dietitian," "registered dietitian," "RD," "RDN," "dietetic technician, registered," or "DTR" without meeting qualifying criteria (a degree, supervised-practice hours, and an examination through a recognized agency) that track the national Commission on Dietetic Registration (CDR) credentialing standards. This differs from Colorado, whose only protection after its 2025 licensure bill was vetoed is a generic anti-fraud statute that doesn't reach the bare word "dietitian" at all — California's statute specifically restricts "dietitian" itself, not just "registered dietitian." Because there is no CA-issued license, the credential practitioners actually hold is the national RD/RDN from CDR, which is a national requirement, not a California one.

Is “Nutritionist” a Protected Title in California?

It does not mention or protect the title "nutritionist" at all — anyone may call themselves a nutritionist in California without any credential.
