Function Health vs Mito Health

Function Health vs Mito Health: the two are priced almost identically, $365 a year for Function and $349 for Mito, but they're built differently. Function tests you twice a year across a very wide 100+ biomarker panel and leaves the interpretation to its app. Mito runs a tighter panel once, then puts a doctor in front of every result. If you want the broadest raw data, Function wins; if you want a physician actually reading your labs, Mito does.

I've personally tested Function Health and worked through its full results experience, and I reviewed Mito Health's panel, pricing, and care model on their own site. To keep the biomarker counts honest I pulled each provider's current list and normalized the marker names, since the same test is often spelled three different ways.

Below: pricing and cost per biomarker, the exact tests each includes and where they diverge, who founded each company (both have a doctor on the founding team, with one important caveat), and the apps.

Function Health vs Mito Health: pricing

Cost per biomarker is the sticker price divided by the number of markers, a rough apples-to-apples figure. It ignores cadence, the app, and any doctor review, which the sections below cover.

Function Health vs Mito Health: biomarkers compared

Function Health's Annual Membership covers 114 biomarkers and Mito Health's Core Panel covers 53. They share 49. 65 are unique to Function Health and 4 are unique to Mito Health.

Function Health vs Mito Health: apps and technology

• Function Health: Function markets Medical Intelligence as proprietary AI, but has published no model card, paper, or named provider. It reads as an orchestration/RAG layer over existing LLMs plus its biomarker data; a genuine trained foundation model can't be verified from public sources.
• Mito Health: Web dashboard plus an AI chat concierge over iMessage; no native app or proprietary trained model announced.

Function Health vs Mito Health: which is better?

For the widest possible panel and a second draw later in the year, Function at $365 is the better raw-data buy, and its app is the more polished place to track trends. Mito, at $349, is the better pick if you'd rather a physician review your results and build a plan than read the numbers yourself, which is the piece Function leaves to software.

One honest caveat on Mito's doctor: co-founder and CMO Dr. Ryan Ware is a Singapore-credentialed physician, not US-licensed, so the clinician reading your labs may not be a US doctor. Check the biomarker breakdown above too, each panel carries markers the other skips. See our Function Health biomarker list for the full breakdown.
