                                As of October 2025, Pennsylvania is one of the states that requires licensure for individuals who wish to legally use the title "Licensed Dietitian-Nutritionist" (LDN) or perform medical nutrition therapy. Understanding these specific regulations is crucial for anyone seeking to practice as a dietitian in the state, as the rules also impact unlicensed nutrition professionals.
