How to read this list
The score is our rubric, not a user average: evidence completeness (a readable page, a one-liner, a published price, platforms, a launch date) plus adoption where a registry number exists. A high score means “we could verify a lot”, not “this will work for you”. The check date next to each row is the honest cut-off.
What would change the ranking
A price change, a product shutting down, or a page that stops being readable. The crawler re-reads every URL daily and stores a text hash, so a silent rewrite is detected and flagged rather than discovered by a reader.

- Our current pick is Function Health (score 71/100). The ranking weighs verified evidence first and adoption second; 3 products met the criteria for this guide. Prices and pages were last checked on 30 Oct 2026. No vendor paid for a position.
- How were these products chosen?
- A real lab panel or clinical programme, not a supplement with a quiz; The operator publishes what is measured; Price is stated, or the page says it is not; Clinician involvement is documented where claimed.
- Why is a product I expect missing?
- Either its official page could not be read when our crawler ran, or it failed one of the published criteria. We do not add products on request without reading their own page first.
