Questions to Ask a Functional Medicine Provider

A functional medicine provider should be able to explain their professional license, scope of practice, testing rationale, evidence standards, costs, and how they coordinate with primary care or specialists.

Ask what license the provider holds, whether they are a physician, nurse practitioner, physician assistant, dietitian, chiropractor, naturopathic doctor, health coach, or another professional, and what services they can legally provide in your state.

Ask what functional medicine coursework, certification, or continuing education they completed. Training can be useful context, but it does not replace state licensure or clinical scope.

Ask what conditions the provider evaluates, what they do not treat, whether they prescribe medications, and when they refer to primary care, urgent care, or specialists.

Ask whether they communicate with your existing clinicians, share lab results, and coordinate when symptoms require conventional diagnosis, imaging, medication changes, or specialist care.

Ask: Why are you recommending this test? Is it validated for the way you intend to use it? How will the result change my treatment? Is there a less expensive or more established alternative? Will my insurance cover it?

Do not assume all testing is inappropriate. Instead, ask whether the evidence supports using the test for your specific situation, and whether guidelines or conventional alternatives exist.

A useful test should have a plausible decision attached to it. Ask what the provider would do differently if the result is normal, borderline, or abnormal.

Ask who manages prescription medications, who monitors side effects, and whether the provider will ever suggest changing a medication prescribed by another clinician. Medication changes should have appropriate medical oversight.

Ask whether supplements are optional, whether the clinic sells them, what evidence supports them, what side effects or interactions are possible, and how long you are expected to take them.

Ask how recommendations will be personalized, measured, and adjusted, especially if they involve restrictive diets, fasting, intense exercise, or major changes for chronic conditions.

Ask how progress is measured, how often you meet, what symptoms or labs are tracked, and what happens if the plan does not help.

Ask for written pricing for visits, labs, supplements, memberships, coaching, and follow-up. Ask what insurance may cover and when outside referral is recommended.

A credible provider should be clear about emergencies, cancer care, psychiatric crises, pregnancy concerns, medication management, complex autoimmune disease, or other issues that require specific conventional care or referral.
