Certified Functional Nutritionist FAQs
About Functional Nutrition Certification
A Certified Functional Nutritionist is a professionally trained individual in evidence-based dietary protocols, nutraceutical interventions, and lifestyle strategies to help support health and function for individuals with chronic conditions, autoimmune disorders, digestive issues, and hormone imbalances.
Traditional nutritionists focus on meeting basic dietary requirements and identifying deficiencies. Functional nutritionists are trained to support optimal health using therapeutic nutrition, specialized diets, and lifestyle medicine in people with chronic inflammatory conditions, autoimmune dysfunction, digestive disorders, and metabolic imbalances. Functional nutritionists are not licensed to treat disease.
