The Board for Certification of Nutrition Specialists℠ (BCNS℠) was established in 1993 and administers the advanced certification for personalized nutrition practitioners: Certified Nutrition Specialist® (CNS®).

We Set Robust Standards for the Practice of Personalized Nutrition:

  • Our certifying board, the Board for Certification of Nutrition SpecialistsSM (BCNSSM), sets the standard for advanced personalized nutrition practitioners via our Certified Nutrition Specialist® (CNS®) credential.
  • We certify practitioners in specialty areas of advanced personalized nutrition.
  • We designate as Fellows those who have distinguished themselves in the area of nutrition science and research.
  • We partner with universities to instill curriculum standards that equip the next generation of nutrition professionals.


BCNS adheres to principles of fairness and due process and endorses the principles of equal opportunity. In administering the certification programs, BCNS does not discriminate or deny opportunity to anyone on the basis of race, color, creed, age, gender, national origin, religion, disability, marital status, parental status, ancestry, sexual orientation, military discharge status, source of income, or any other status protected by applicable law. All candidates for certification will be judged solely on the published eligibility criteria determined by the Board.
