Functional and integrative medicine are not recognized medical specialties. They do not have accredited residency training or board certification through nationally recognized bodies such as the American Board of Medical Specialties or training oversight by the Accreditation Council for Graduate Medical Education. In contrast, board-certified physicians complete years of standardized residency and fellowship training, pass rigorous specialty board examinations, and participate in ongoing recertification to maintain clinical competence. Importantly, good physicians across all legitimate specialties already prioritize prevention, longevity, and whole-person care—these values are not unique to “functional” or “integrative” frameworks. In practice, those labels function largely as branding rather than disciplines, and may imply a level of specialization or evidence-based authority that does not formally exist. While some clinicians using these terms practice responsibly, the absence of standardized training, regulation, and accountability makes the model vulnerable to excessive testing, costly supplement regimens, and fear-based explanations, which can become confusing, misleading, or at times exploitative, particularly for patients who are medically anxious, chronically ill, or searching for certainty.
