Ph.D. Integrative and Functional Nutrition

Admissions Requirements

The following is a list of required and preferred criteria for acceptance into the Ph.D. in Integrative and Functional Nutrition.  Each applicant is assessed individually and all materials including academic transcripts, statement of interest, professional experience, and personal interview are used to determine the appropriateness of each candidate.   

• Completion of a master’s degree from a regionally accredited university with GPA of 3.3 or above (on a scale of 4.0). 
  • Those with a master’s GPA of 3.0 to 3.3 may be conditionally accepted and required to take a lighter course load and achieve a B or above in all coursework for at least one year. 
  • Preference is given to those with a BS or M.S. in the health, life, or physical sciences (e.g., nutrition, exercise physiology, biochemistry, chemistry) or whose academic transcripts demonstrate significant science coursework. 
  • Alternative degrees will be considered on an individual basis. 
• Transcripts from an accredited university showing completion of the following three pre-requisite science courses with a B or above within the past 10 years*. If any of the prerequisite science courses are taken at University, a grade of 75% or above is required. Course equivalencies between Saybrook University and Straighterline can be found at https://www.straighterline.com/colleges/saybrook-university/. Please note that if you plan to pursue other educational or credentialing experiences after you complete your Saybrook University journey, you must check with the other institutions/organizations first to determine whether they accept Straighterline courses. 
  • 3 credits Human Nutrition 
  • 3 credits Biochemistry or Organic Chemistry 
  • 3 credits Anatomy and/or Physiology 
• Those lacking one or more of these pre-requisite courses may be accepted but will be required to add the course(s) to their doctoral program at Saybrook. 
• Applicants whose pre-requisite coursework was completed more than 10 years prior to applying, but who have recent related work experience (e.g., Registered Dietitians) may waive some pre-requisite requirements. 

Applicants for the doctoral degree in Integrative and Functional Nutrition must submit:  

• Official transcripts from all undergraduate and graduate universities; 
• A 250-500-words personal statement explaining their professional interest in pursuing the Ph.D. in Integrative and Functional Nutrition; 
• A current resume or CV; 
• Upon request, some students may be required to provide a sample demonstrating academic writing skills. Writing samples and other Admissions documents must be solely and independently authored by the applicant, not professionally edited, and written within the past ten years. Due to the importance of scholarly writing standards, all Ph.D. IFN students will be required to take the graduate level academic writing course. Writing samples will be analyzed to assess whether the applicant can be waived from this requirement. Note that if plagiarism is found, it can be disqualifying for admission. Plagiarism is defined in the Saybrook catalog section, “Policy on Academic Honesty (Plagiarism) and Authorship.
