MD or ND? A guide to find the right functional medicine doctor near you in San Francisco
*IV Ketamine, NR, and NAD+ have been used clinically off-label for decades. They are not FDA approved for the treatment of any psychiatric or pain condition. All medical treatments carry risks and benefits that you must discuss with a doctor at Clarus Health to learn if these therapies are right for you.

Searching for a functional medicine doctor near you usually means you've already done the conventional medicine thing.
The blood work came back "normal," but you're not actually feeling any better.
That experience is what drives people to functional medicine.. The problem is that when you search "functional medicine doctor near me," the results are a minefield. Medical doctors, naturopaths, chiropractors, and health coaches all show up under the same label. Their websites look identical but their credentials certainly are not!
Here's how to sort through it before you book.

Functional medicine is root-cause care. Instead of matching your symptoms to a diagnosis and your diagnosis to a prescription, a functional medicine doctor investigates what's actually driving your condition: your hormones, genetics, gut health, metabolic function, stress physiology. Then they build a treatment plan around you, not around a protocol.
If you've been told your labs are normal while feeling anything but, a good functional medicine doctor is going to find things a 15-minute primary care appointment would never look for.
This isn't fringe medicine. A 2019 study in JAMA Network Open compared over 7,000 patients treated at Cleveland Clinic's Center for Functional Medicine against matched patients in standard primary care. The functional medicine group showed significantly greater improvements in physical and mental health quality of life at both six and twelve months — the first large-scale clinical validation the model had ever had.
Functional medicine is built for people who are genuinely unwell but keep getting told nothing is wrong.
If any of that sounds familiar, you're the patient functional medicine was designed for. Finding the right physician near you is worth the effort.
This is the most important thing to know before you book with anyone.
Functional medicine is not a licensed specialty. The Institute for Functional Medicine, the field's leading certifying body, offers its training to MDs, DOs, naturopaths, chiropractors, nurses, and health coaches. The certificate doesn't change what any of them are legally allowed to do: that is determined by their license.
The most common source of confusion is MDs versus NDs: medical doctors versus naturopathic doctors. Both finish four-year doctoral programs. Both can call themselves "doctor" in California. But the training gap between them is significant: a medical doctor completes 12,000 to 16,000 hours of supervised clinical experience across medical school and a mandatory three-to-seven-year residency. For comparison, CNME-accredited naturopathic programs require a minimum of 1,200 hours of clinical training and no required post-graduate residency, unlike the residency required of medical school graduates.
Under California state scope-of-practice rules, a naturopathic doctor cannot prescribe most medications without MD supervision, can order imaging but cannot interpret it, and cannot legally use the title "physician."
An MD carries none of those restrictions. And when you're dealing with a complex case - hormones, treatment-resistant depression, chronic systemic symptoms - you want the person treating you to have the full medical toolkit.
Before booking anywhere, pull up the Medical Board of California's website and verify the license. "MD" or "DO" means physician. "ND" means naturopath. No license listed means health coach.
Beyond credentials, ask whether they can manage your case if it gets complicated. Ask what advanced treatments they offer in-house, and whether the practice is set up to handle the full picture of your health, the way physician-led functional medicine is designed to do. Hormone therapy, interventional procedures, and treatments like IV ketamine, Stellate Ganglion Blocks, or Spravato are physician-only - and they're often exactly what patients with treatment-resistant conditions have been waiting for.
