Alloy vs Function Health

Vial Take

Both Alloy and Function Health sit in the top quartile of their respective categories with clean federal records and similar transparency gaps, mainly undisclosed pharmacy partners and missing NPI registration, so neither gives you a fully open supply chain. The bigger difference is what you're actually buying: Alloy delivers menopause-focused clinical care through board-certified OB/GYNs, while Function Health is a diagnostic platform built around deep lab panels for metabolic and longevity tracking, not treatment. If you're looking to manage symptoms, Alloy is the relevant tool; if you want comprehensive baseline data to bring to any provider, Function fills that lane instead.
