Why Work With a Registered Dietitian?

While many people call themselves nutritionists, only those who meet strict national standards can use the title Registered Dietitian Nutritionist. This distinction matters—RDNs are uniquely trained and qualified to:

  • Review lab work, medications, and health history to inform care

  • Develop personalized nutrition plans based on science, not trends

  • Provide Medical Nutrition Therapy for managing chronic conditions

  • Translate complex nutrition science into practical, sustainable guidance

All dietitians are nutritionists, but not all nutritionists are dietitians. Choosing a registered dietitian ensures you're getting trustworthy, evidence-based support tailored to your health needs.
