Frequently Asked Questions

How are functional medicine scored on BestDosage?

Each functional medicine is scored across five weighted criteria drawn from public data: reviewed reputation, listed credentials, professional presence, profile depth, and location detail. Scores run to 10, and we publish one only at 7.0 or above — below that a provider is listed without a score, usually because our data on them is limited.

How do I choose the right functional medicine?

Start by reviewing BestDosage Scores and reading patient reviews. Consider factors like location, telehealth availability, insurance acceptance, and specialization areas. You can also use our comparison tool to evaluate providers side by side, or take the Wellness Match quiz.

What credentials should I look for in functional medicine?

Look for board certifications, state licensing, and continuing education. Our scoring weights listed credentials and verification at 25% of the total. Those credentials are recorded as published by the practitioner or their public business listing — we do not independently verify licensure against state boards, so confirm it directly with the issuing board before booking.

Is the BestDosage directory free to use?

Yes, browsing the directory, viewing profiles, and comparing providers is completely free. Our scoring methodology is published openly on our About page for full transparency.
