The CNS®

The Certified Nutrition Specialist® credential (CNS®) is the most advanced certification for personalized nutrition practitioners. Certified Nutrition Specialists practice science-based personalized nutrition therapy to power people to health. They are spearheading the transformation from population-based to personalized nutrition, and from disease care to authentic health care. The CNS designation demonstrates to colleagues, clients, employers and the public that certified individuals have the knowledge and proficiency required for advanced professional nutrition practice. To be eligible for the CNS credential, an individual must have a minimum of a master’s degree in nutrition or a related health science, meet specified coursework requirements, achieve a passing score on the rigorous Certification Examination for Nutrition Specialists, and document achievement of a set of clearly defined practice competencies in 1000 hours of Supervised Practice Experience (SPE).
