A Certified Nutrition Specialist (CNS) is a credential awarded by the Board for Certification of Nutrition Specialists (BCNS) to advanced-level nutrition professionals. These specialists utilize a science-based, personalized approach to medical nutrition therapy, often focusing on identifying and addressing the root causes of health issues through diet and lifestyle interventions.
Becoming a CNS Nutrition Specialist
Becoming a CNS requires a rigorous educational and practical pathway:
- Advanced Education: Candidates must hold a master's or doctoral degree in nutrition or a related field from an accredited institution. The curriculum typically emphasizes the science and biochemistry of nutrition and functional medicine.
- Supervised Practice: A minimum of 1,000 hours of supervised clinical practice is required. This hands-on experience allows candidates to apply their knowledge in real-world settings.
- Comprehensive Examination: Candidates must pass the Certification Examination for Nutrition Specialists, a challenging board exam administered by the BCNS.
This extensive training equips CNS practitioners to work in various environments, including private clinical practices, wellness centers, and research institutions.
Role and Focus of a CNS
CNS professionals are known for their personalized approach, considering an individual's unique biochemical individuality, genetic factors, and lifestyle to create customized dietary plans. They often focus on preventative care and wellness. The BCNS is accredited by the National Commission for Certifying Agencies (NCCA), which speaks to the standard of the credential.
CNS vs. Registered Dietitian (RD/RDN)
While both Certified Nutrition Specialists (CNS) and Registered Dietitians (RD or RDN) are qualified nutrition professionals, their training and typical focus can differ.
| Feature | Certified Nutrition Specialist (CNS) | Registered Dietitian (RD/RDN) |
|---|---|---|
| Education Level | Master's or Doctoral degree typically required | Bachelor's or Master's degree typically required |
| Approach | Personalized, functional, integrative | Conventional, population-level |
| Practice Focus | Root-cause analysis, private practice, wellness | Institutional settings (hospitals, nursing homes) often |
| Governing Body | Board for Certification of Nutrition Specialists (BCNS) | Commission on Dietetic Registration (CDR) |
Both credentials allow professionals to practice medical nutrition therapy in many states, and the choice between seeking care from a CNS or RD depends on the individual's needs and the type of nutritional guidance they seek. It is also important to note the distinction between a Certified Nutrition Specialist and a Clinical Nurse Specialist, as they have different roles despite sharing the CNS acronym.
State Recognition and Practice
The CNS certification is recognized by many state licensing boards, which can provide a pathway to practice medical nutrition therapy and potentially receive insurance reimbursement in some areas.
Conclusion
A Certified Nutrition Specialist is a highly qualified nutrition professional who has met advanced educational, experiential, and examination requirements. Their focus on personalized, science-based, and often functional nutrition therapy makes them a valuable resource for individuals seeking to address health concerns through diet and lifestyle interventions. The CNS credential represents a high standard in the field of nutrition certification.
