How did Codex pick the best functional medicine in London?

We started from the full set of claimed and verified functional medicine practitioners listed on Codex in London, then ranked by client rating (weighted by review count) and trust tier. Only profiles that have been claimed or verified by their owner qualify.

Are these functional medicine listings in London sponsored?

No. Ranking is editorial. Codex does not accept payment for placement on best-of pages — verified practitioners are ranked by client reviews and credentials only.

How often is the best functional medicine list for London updated?

The list rebuilds automatically from our directory whenever new reviews are posted or new practitioners are verified. The page is recrawled and republished within 24 hours.

What does "verified" mean on Codex?

Verified means we've reviewed the practitioner's credentials, identity, and (where applicable) insurance. Claimed means the practitioner has taken ownership of the profile but verification is still in progress.
