Iowa 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 →
Iowa licenses dietitians through the Iowa Board of Dietetics, housed within the Department of Inspections, Appeals, and Licensing (DIAL), under Iowa Code Chapter 152A and Iowa Administrative Code 481, Chapters 921-924. Iowa issues only a single "dietitian" license — there is no separate "nutritionist" credential; nutrition assessment and nutrition counseling are defined and regulated as part of licensed dietetic practice itself.

Iowa Administrative Code 481-921.1 defines only "dietetics," "registered dietitian," and "licensee" (a person licensed as a dietitian) — there is no separate "nutritionist" license category. "Nutrition assessment" and "nutrition counseling" are themselves defined terms describing components of licensed dietetic practice (481-921.1, 921.2) rather than a distinct, separately licensable nutritionist profession. In practice, anyone providing nutrition assessment or counseling services in Iowa must hold the dietitian license — there is no lawful unlicensed "nutritionist" title/practice track distinct from it, per secondary practitioner-guidance sources describing Iowa as an "exclusive scope of practice" state.
