***Due to the holidays and the large number of calls and emails regarding CNS annual fees and recertification, it is taking longer than usual for us to respond. You will not be penalized for late payments and late recertification applications.  Thank you for your patience during this very busy transition time.***

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

Please note: CNSs are NOT required to be a paying ANA member. CNS certification and ANA membership are two separate things.
