The two get lumped together a lot. They shouldn’t be.
Holistic medicine is a philosophy of care. Anyone can adopt it, from a board-certified MD to a weekend-workshop wellness coach. Naturopathic medicine is a distinct medical system with accredited schools, board exams, and licensure in specific US states. And functional medicine is a third model that most people confuse with both.
This article lays out the actual differences: training, licensing, what each treats well, what insurance covers, and how to tell which one fits what you’re dealing with.
Quick takeaway
- Holistic medicine is a philosophy (whole-person care). Not a regulated credential.
- Naturopathic medicine is a licensed medical system. NDs graduate from 4-year accredited schools and are licensed in 26 US jurisdictions.
- Functional medicine is a model, not a license. Practitioners use their base license (MD, DO, ND, NP) plus additional certification.
- All three overlap on the idea of root-cause care. They diverge on training, tools, and legal scope.
The One-Sentence Answer
Holistic is the mindset, naturopathic is the credential, functional is the diagnostic method.
A holistic MD, a naturopathic doctor, and a functional medicine practitioner can all treat the same patient with overlapping ideas. What differs is what they can legally do, how they were trained, and how they investigate what’s wrong.
Holistic vs Naturopathic vs Functional: Side by Side
The single table most “vs” articles skip. Read across each row to see how the three actually differ.
| Aspect | Holistic Medicine | Naturopathic Medicine | Functional Medicine |
| What it is | A philosophy of whole-person care. Any type of clinician can adopt it. | A distinct medical system focused on natural therapies and self-healing. | A model that hunts root causes using advanced labs plus lifestyle. |
| Who practices it | MDs, DOs, nurses, NDs, therapists, chiropractors, coaches. No single credential. | Naturopathic Doctors (NDs) trained at accredited 4-year schools. | Usually MDs, DOs, NPs, or NDs with additional functional medicine training (IFMCP is the gold standard). |
| Training path | Varies widely. Ranges from board-certified physicians to weekend workshops. | 4-year naturopathic medical school + NPLEX board exam. Only from CNME-accredited schools. | Base medical license + IFM certification (AFMCP course, 7 modules, exam). |
| Licensed | The title “holistic doctor” isn’t a regulated credential. | Licensed in 26 US jurisdictions. Unregulated in the rest. | Not a separate license. Practitioner uses their base medical license. |
| Typical tools | Nutrition, mind-body work, acupuncture, massage, sometimes standard medicine. | Botanical medicine, homeopathy, clinical nutrition, hydrotherapy, physical medicine. | Expanded lab panels, personalized nutrition, targeted supplements, medication when needed. |
| Best for | Broad wellness and mind-body support alongside conventional care. | Prevention, chronic conditions, mild-to-moderate illness with natural first-line care. | Chronic illness with a testable underlying pattern (autoimmune, metabolic, gut, hormonal). |
| Insurance | Depends on provider and their base license. | Rarely covered; some licensed states cover partial visits. | Usually out-of-pocket for visits and specialty labs. |
Holistic Medicine
Holistic medicine treats the person, not just the symptom. It looks at body, mind, spirit, lifestyle, and environment together. That framing is useful. It’s also completely unregulated as a title.
Anyone can call themselves a “holistic doctor.” A board-certified family medicine physician who focuses on lifestyle change qualifies. A chiropractor who runs a wellness clinic qualifies. So does someone with an online certificate and no medical training.
The closest formal credential is the American Board of Integrative Medicine, which certifies MDs and DOs who have completed extra training in integrative and holistic care. If you want the whole-person philosophy delivered by someone with real medical credentials, that’s the certification to look for.
What holistic practitioners typically use
- Nutrition and dietary counseling
- Mind-body work: meditation, yoga, breathwork
- Acupuncture and massage
- Herbal and supplement recommendations
- Sometimes standard medicine, if the practitioner is licensed for it
Naturopathic Medicine
Naturopathic medicine is a distinct medical system. Practitioners called Naturopathic Doctors (NDs) graduate from accredited naturopathic medical schools (Bastyr University, National University of Natural Medicine, Southwest College, Canadian College, and a few others) after a four-year program covering biomedical sciences plus botanical medicine, clinical nutrition, homeopathy, physical medicine, and counseling.
NDs sit for the NPLEX (Naturopathic Physicians Licensing Examination) board exams. In licensed states, they can order labs, diagnose, and prescribe within a defined scope.
The licensing situation (this matters)
Per AANMC’s licensure map, NDs are currently licensed in 26 US jurisdictions. That means in about half the country, the title “naturopathic doctor” isn’t legally recognized, which changes what services they can offer and how visits get billed.
If you’re considering an ND, always check your state’s licensing board. In an unlicensed state, an “ND” from a legitimate accredited school still has real training, but their legal scope of practice is narrower and their advice can’t substitute for a licensed physician’s care.
Six naturopathic principles (from the profession’s charter)
- First, do no harm
- The healing power of nature
- Identify and treat the causes
- Treat the whole person
- Physician as teacher
- Prevention
Functional Medicine
Functional medicine is a model of care, not a license. Practitioners use their base medical license (MD, DO, ND, NP, PA) and add functional medicine training on top.
The strongest formal credential is the IFMCP (Institute for Functional Medicine Certified Practitioner), which requires completing the AFMCP course, all seven advanced practice modules, a case report, and a certification exam. A 2019 study by Beidelschies and colleagues in JAMA Network Open compared 7,252 patients at the Cleveland Clinic Center for Functional Medicine against matched primary care patients and found significantly better physical health outcomes at 6 and 12 months.

Which One Is Right for You?
The best choice depends less on the label and more on what you’re dealing with. Here’s the practical breakdown.
Pick holistic when
- You want your existing MD or GP to take a wider view of your health without leaving conventional care
- You want mind-body support alongside standard medicine (chronic stress, mild anxiety, sleep issues)
- You’re happy with a broad philosophy rather than a specific diagnostic protocol
Pick naturopathic when
- You live in a state that licenses NDs and want a licensed primary care option that starts with natural first-line therapies
- You have chronic but not severe conditions that respond to nutrition, botanicals, and lifestyle
- You prefer prevention-first care and don’t want medication as the default
Pick functional when
- You have a chronic issue and standard testing has said “everything’s normal” but you clearly aren’t
- You want deeper labs (hormones, gut, micronutrients, autoimmune markers) and a plan built on those results
- You’re willing to invest time and out-of-pocket costs for the wider workup
Cost and Insurance (the Practical Layer)
Straight talk: expect most of this care to be out of pocket. That’s changing slowly but it’s still the default.
- Holistic doctors who are MDs or DOs sometimes bill insurance for base visits. Their supplement recommendations and specialty labs usually aren’t covered.
- Naturopathic doctors are covered by some insurance plans in licensed states. Vermont, Washington, and Oregon have the widest coverage. Most other states cover very little.
- Functional medicine visits are usually out of pocket. Expanded lab panels can run $300 to $1,500 depending on scope. Some practitioners offer sliding-scale or package pricing.
HSA and FSA funds usually cover both visits and labs when there’s a documented diagnosis. Ask before booking.
Red Flags for Any of the Three
Legitimate practitioners across all three models share the same discipline. Fakes across all three share the same warning signs.
- No listed credentials or license anywhere on their site
- Won’t state their base training when asked directly
- Sells their own supplement line and pushes it hard before any labs are run
- Claims to “cure” chronic disease
- Advises against necessary conventional care (chemo, insulin, thyroid replacement) without a plan that works
- Refuses to coordinate with your other doctors
FAQs
Can a naturopathic doctor prescribe medication?
Depends on the state. In licensed states, NDs can typically prescribe within a defined formulary (though narrower than an MD or DO). In unlicensed states, they can’t prescribe at all. Always check your state’s ND scope of practice.
Is naturopathic medicine covered by insurance?
Rarely, and inconsistently. A handful of states with strong ND licensure (Washington, Oregon, Vermont) have better insurance coverage. Most plans don’t cover ND visits at all. Check with your insurer before booking.
Is holistic medicine legit?
The philosophy is legit and increasingly recognized. The title itself isn’t regulated, which means the range of quality is huge. Verify the practitioner’s base training and license before signing on.
Can I see all three types at the same time?
Yes, and many patients do. The best outcomes usually come from a licensed physician handling the medical layer and a naturopathic or functional practitioner handling the lifestyle, nutrition, and lab-driven layer. Make sure they coordinate.
Which one is closest to what a conventional MD does?
Functional medicine, when practiced by a licensed MD or DO. It uses the same base training plus additional certification, orders labs, and can prescribe. Holistic is broader in philosophy; naturopathic is a separate medical system with its own training path.
Bottom Line
Don’t pick a label. Pick a practitioner. The training, license, and how they investigate what’s wrong matter more than the words on the sign.
At Advanced Integrated Health, we combine functional medicine testing with holistic principles under a licensed medical model. Our functional lab testing catches what standard panels miss, and every plan is built on labs first, not supplement guesses.
