The Kharrazian Institute (KI) and the School of Applied Functional Medicine (SAFM) both offer online functional medicine training. Both emphasize clinical application over theory. Both attract practitioners who want to do more for their patients than standard care allows. The programs are designed for different practitioners at different stages, and the clinical depth they deliver is not equivalent.
Who Each Program Is Designed For
SAFM serves a broad audience that includes health coaches, nutritionists, nurses, and physicians. The program is accessible to practitioners who may not hold a clinical license, and the training is structured to be applicable across a wide scope-of-practice spectrum, including health coaching and wellness consulting.
KI is built for licensed healthcare professionals, from those beginning their functional medicine education to experienced clinicians managing complex chronic cases. MDs, DOs, DCs, NDs, NPs, PAs, acupuncturists, and registered dietitians make up the core audience. The curriculum starts with the Essentials of Functional Medicine and scales through 19 clinical topic areas, with coursework designed so that practitioners can implement clinical strategies with their patients immediately.
Program Structure and Depth
SAFM uses a two-semester model. The Core 101 semester covers etiology of disease, nutrient and supplement fundamentals, and introductory lab work. The Advanced 202 semester builds on that foundation with more clinical topics. Additional six-week deep-dive courses on specific conditions are available separately. A practitioner incubator membership provides ongoing Q&A access and peer mentoring.
KI is a four-pillar system. The foundation is 19 courses totaling 200 hours taught by Dr. Datis Kharrazian, covering clinical areas from neuroinflammation and autoimmunity to cognitive decline, chronic infections, hormone imbalances, and cardiovascular and neurovascular syndromes. Beyond the foundational courses, KI delivers monthly five-hour Master Classes by leading functional medicine clinicians, the Clinical Mastership Training Program with over 100 hours of real-case grand rounds, expert interviews, physical examination training, and lab interpretation modules. A private peer-to-peer forum connects practitioners globally.
The difference in scope is significant. SAFM covers functional medicine principles across two semesters with condition-specific electives. KI delivers 300+ hours across 19 clinical topic areas, with new content added every month and a grand rounds program that follows real patients from intake through outcome.
Teaching Approach
SAFM's teaching model centers on self-paced video and audio lessons with live coaching calls led by founder Tracy Harrison. The emphasis is on making functional medicine concepts accessible and actionable, with shareable client handouts and peer group meetings built into the experience. The approach works well for practitioners building a functional medicine consulting practice or integrating basic functional medicine concepts into an existing wellness practice.
KI teaches a clinical sequence of thought for each condition area. Rather than providing supplement protocols or condition checklists, each course trains the practitioner to identify the primary driver of a patient's dysfunction, determine the order of intervention, and adjust the strategy based on clinical response. The Clinical Mastership Training Program makes this concrete: Dr. Kharrazian walks through his entire workup for complex referral cases, including the decision points where the clinical strategy had to change because the patient didn't respond as expected. This level of clinical transparency is rare in functional medicine education.
Certification
SAFM offers the Applied Functional Medicine for Coaching (AFMC) credential, which requires completion of both semesters plus additional requirements. The AFMC is SAFM's own credential and is not tied to a major medical accrediting body.
KI offers four certification tracks based on licensure status and hours completed. Licensed practitioners can earn the Certified Functional Medicine Clinician (CFMC) at 68 hours or the Advanced Functional Medicine Clinician (AFMC) at 300 hours. Non-licensed health consultants earn the CFMHC or AFMHC. The 300-hour AFMC is the most comprehensive functional medicine credential available. Annual recertification requires 12 hours of continuing education with no fee.
CE and CME Credits
SAFM does not hold ACCME accreditation. CE credit availability through SAFM is limited.
KI is an approved CPD provider in the United Kingdom and over 50 countries, with specific CE credit approvals for DCs, NDs, acupuncturists, and medical physicians (MD, DO, PA, NP). Credit hours and approving organizations vary by license type and state.
Cost
SAFM's semester programs are typically in the range of $3,000 to $6,000 per semester, with a total investment for full certification estimated at $8,000 to $12,000.
KI membership is $399 per month or $3,999 per year, with a $995 one-time setup fee on the monthly plan. The annual plan saves $1,784. Membership includes access to every course, every Master Class, the Clinical Mastership Training Program, the practitioner forum, and the certification pathway. There are no separate course fees or add-on charges. Practitioners who start with the free 7-day trial can subscribe at $299 per month with the enrollment fee waived.
Who Each Program Serves Best
SAFM is a fit for health coaches, nutritionists, and practitioners who want a structured introduction to functional medicine with community support and coaching access. The two-semester format provides a clear learning pathway with an emphasis on accessibility.
KI serves licensed healthcare professionals at every stage of their functional medicine education, from practitioners just beginning to integrate functional medicine into their practice to experienced clinicians managing the most complex chronic cases. The 19-course curriculum starts with the Essentials of Functional Medicine and scales to advanced clinical topics like neuroinflammation, neuroimmunology, and blood-brain barrier dysfunction that reflect Dr. Kharrazian's research background. The real-case grand rounds program, monthly expert Master Classes, and the breadth of 19 clinical topic areas make KI the more comprehensive platform for practitioners who want both a foundation and the depth to keep building on it throughout their career.
