Vial Take

Near-identical on the public record; the choice comes down to fit: treatment type, state availability, and pricing.

Biggest Differences

  1. Physician disclosure
    Function Health publishes named clinical leadership you can research before signing up; InsideTracker describes its clinical team in aggregate without identifying specific physicians.
  2. Operating history
    InsideTracker has been operating since 2009 (17+ years of visible track record); Function Health launched in 2021, giving you 12 fewer years of public record to evaluate.
