A registered dietitian (RD) is a licensed healthcare professional who has completed a bachelor's degree in nutrition, an accredited supervised practice program, and passed a national certification exam. A nutritionist is a broader term that is not consistently regulated -- in many states, anyone can use the title without specific credentials. If you need medical nutrition therapy for a health condition, always choose a registered dietitian.
Education and Credentials
- Registered Dietitian (RD/RDN): Bachelor's or master's degree in dietetics, 1,000+ hours supervised practice, national board exam, state license, continuing education requirements
- Certified Nutrition Specialist (CNS): Master's or doctoral degree, 1,000 supervised hours, board exam -- a legitimate advanced credential
- Nutritionist (unregulated): May have formal training or none at all. Credential requirements vary dramatically by state.
When to See a Registered Dietitian
- Managing a medical condition: Diabetes, kidney disease, heart disease, celiac disease, or eating disorders
- Food allergies or intolerances: An RD can design a complete diet that avoids triggers without creating deficiencies
- Pregnancy or breastfeeding: Specialized nutritional needs that affect two people
- Post-surgical nutrition: Bariatric surgery, cancer treatment, or GI surgery recovery
- Pediatric nutrition: Growth concerns, picky eating, or childhood obesity
When a Nutritionist May Be Sufficient
If you are generally healthy and looking for guidance on meal planning, weight management, sports nutrition, or healthier eating habits, a well-credentialed nutritionist or health coach may meet your needs. Look for certifications like CNS, CISSN, or relevant master's degrees. Many practitioners use client reviews and testimonials to build trust and demonstrate their expertise.
How to Verify Credentials
- Search the Commission on Dietetic Registration's database for RDs
- Check your state's dietitian licensing board
- Ask the practitioner directly about their education, certification, and supervised practice hours
