Oklahoma Dietitian License Requirements (2026)
Compiled and verified against primary state-board, CDR, and ACEND sources by DietitianLicense — cite-or-deny, with no invented figures. How we source & verify →
Oklahoma licenses dietitians under the Oklahoma Licensed Dietitian Act (59 O.S. §§1721 et seq.), administered by the Oklahoma State Board of Medical Licensure and Supervision through its Licensed Dietitians Committee. The Act protects the titles "licensed dietitian"/"provisional licensed dietitian" (and the letters "L.D."/"PLD") as well as the nationally-registered "registered dietitian"/"R.D." title, but does not restrict use of the word "nutritionist" — Oklahoma licenses dietitians only, and does not otherwise limit the broader practice or title of nutrition.

Oklahoma's Licensed Dietitian Act (59 O.S. §1736, Titles and abbreviations) protects only "licensed dietitian," "provisional licensed dietitian," the letters "L.D."/"PLD," and the nationally-registered "registered dietitian"/"R.D." title (tied to CDR registration) — it does not name or restrict "nutritionist" as a protected title. The Board's own materials confirm Oklahoma licenses dietitians only and does not otherwise limit the practice of nutrition, so unlicensed individuals may lawfully use the title "nutritionist" in Oklahoma.
