The health and wellness industry is growing which means there are more health and wellness professionals that provide valuable care. Within the field of nutrition, there are registered dietitians, certified nutrition specialists, clinical nutritionists, functional nutritionists, health coaches, nutrition coaches, and many more titles. Since a lot of these providers focus on nutrition care, it can be confusing to differentiate what these different titles mean.
What is a Registered Dietitian (RD) or Registered Dietitian Nutritionist (RDN)?
The Registered Dietitian (RD) credential was established by the Academy of Nutrition & Dietetics just over 100 years ago and therefore is the most recognized and supported credential when it comes to nutrition therapy in healthcare. As the trailblazers in nutrition therapy, RD’s also receive recognition as practitioners when it comes to healthcare legislation, licensure and insurance contracting. This makes nutrition care more accessible and affordable for many who rely on their insurance benefits to receive nutrition therapy.
Requirements for Registered Dietitians
Credentials for Registered Dietitians are granted by the Board of Dietetics in each state. The Board requires the following:
Earn an accredited bachelor’s in nutrition & dietetics; starting in 2024, the minimum education requirement will be a master’s degree.
Complete an ASCEND approved dietetic internship of 1,200 hours under the supervision of a licensed professional.
Pass the Commission on Dietetic Registration (CDR) exam.
Obtain a state license where applicable, most states don’t require a practice license.
Maintain state license and registration by completing 75 continuing education credits every five years.
What is a Nutritionist?
Unlike the path to becoming an RD, becoming a nutritionist is more arbitrary. As there is no overseeing board or federal or state legislation in most cases, technically anyone can call themselves and become a “nutritionist”. This means that anyone with an online certificate or general knowledge of nutrition principles can call themselves a nutritionist. They just can’t claim to be “licensed” or “certified”. If you’re in a state that lacks legislation around nutrition practices, do your due diligence. These states include (but are not limited to):
Arizona, California, Colorado, Idaho, Oklahoma, Oregon, Pennsylvania, Texas, Washington and many more.
While anyone can call themselves a nutritionist, there are a few credentials like the Certified Nutrition Specialist (CNS) or the Certified Clinical Nutritionist (CCN) that require a higher standard of education and training.
What is a Certified Nutrition Specialist?
The Certified Nutritionist Specialist (CNS) is the most widely recognized non-dietetics credential. The CNS is a federally recognized board certification with state-by-state licensure in states that do offer licensure for Nutritionists. As certified practitioners, a CNS is well versed in clinical nutrition, nutritional biochemistry, therapeutic diets and supplements to provide medical nutrition therapy. Depending on state licensure and insurance companies, contracting and coverage for nutrition counseling is limited.
Requirements for Certified Nutrition Specialist
Credentials for Certified Nutrition Specialists are granted by the Board for Certification of Nutrition Specialists (BCNS) associated with the American Nutrition Association. BCNS requires the following:
Master’s degree in nutrition or a related field from a regionally accredited university, with coursework that covers clinical nutrition, biology, microbiology, nutritional biochemistry, physiology and anatomy.
Completion Of 1,000 hours of a supervised experience
Earn a passing score on the CNS board exam.
Completion of 75 continuing education credits every five years to maintain certification.
What is the Difference between a CNS Nutritionist and a RD Nutritionist?
Nutritionists and Dietitians both have career paths in the health and wellness industry, focusing on finding the best diet and foods to help people meet their health needs. Each one is trained and qualified to develop custom meal plans for their clients to help them reach their nutritional health goals. There are a few differences between them and knowing these differences can help you determine which would be the right fit for you.
Registered Dietitians are trained for acute care, such as hospital care, including parenteral (tube) nutrition to supplement conventional medicine. They follow federal nutrition guidelines and are trained to apply USDA’s resources in various settings like hospitals, health departments, food manufacturing, school systems, or college campuses.
Certified Nutritionists work within the realm of functional medicine, which aims to heal the root cause of chronic conditions. As part of a holistic and integrative approach, CNS's aim to treat the root cause through personalized nutrition for healing and preventive care. CNS’s are typically in found private clinical practice, nutrition research, clinical educators or as nutrition professors.
