To address the need for nutrition professionals, our M.S.-to-Ph.D. Pathway in Integrative and Functional Nutrition program prepares you to become a highly competent practitioner, while saving you time and money in the process.

In this online dual-degree pathway, you will enter directly into the Ph.D. program and follow the advanced research course sequence required of doctoral students. When you have completed the 40 credits required for the master’s degree, you will be awarded your M.S. in Integrative and Functional Nutrition degree without pausing or taking time off from your Ph.D. program.

The online M.S.-to-Ph.D. Pathway in Integrative and Functional Nutrition program fulfills the current academic requirements for the Certified Nutrition Specialist (CNS) credential from the American Nutrition Association. This dual-degree nutrition program is also designed to meet the core academic requirements for the Certified Clinical Nutritionist (CCN) credential from the Clinical Nutrition Certification Board.

If you are interested in seeking the Registered Dietitian (RD) credential upon completion of the M.S.-to-Ph.D. Pathway in Integrative and Functional Nutrition program at Saybrook University, please visit the website of the Accreditation Council for Education in Nutrition and Dietetics (ACEND). ACEND® policies for Individualized Supervised Practice Pathways (ISPPs) allow individuals holding a doctoral degree without a Didactic Program in Dietetics (DPD) verification statement to apply for an ISPP; however eligibility requirements and options may vary by program. You can see which Dietetic Internships, Coordinated, or Didactic programs currently offer ISPPs by visiting Accredited Education Programs. Doctoral degree holders without a DPD verification statement must attend an ISPP that is approved to offer a track for individuals with a doctoral degree. Students interested in applying to an ISPP should research the eligibility requirements of the program where they intend to submit an application, including whether you are required to locate your own preceptors, and then contact the program director. Individuals with work experience should also inquire whether the program grants credit for specific competency requirements through an assessment of prior learning.
