What is a RDN?
A registered dietitian nutritionist (RDN) is a food expert, and the only healthcare professional equipped to offer medical nutrition therapy (MNT).
After completing the required undergraduate coursework (and soon graduate coursework- a master’s degree will be required beginning 2024), a RDN hopeful will complete an extensive supervised practice internship, take a national certifying exam, apply for state licensure and maintain credentials with continuing education.
In juxtaposition, nutritionist is not a protected title or credential. There’s currently no regulation of the term, nor requirements for its use.
