Tati and Ray B.
We enjoy Function Health! This is the second year both my husband and I purchased our memberships. The labs are insightful and helpful in assisting us to optimize and tune up our health! Price per person is amazing for 160 biomarkers compare to what we would pay for all this labs on our own. Prevention is the key! Thank you dr. Mark Hyman and Function Health! We highly recommend Function Health to everybody!

Chelsie
I love Function Health! I really appreciate all of the details I receive back. I love that you can compare across time periods how your results have changed. I do wish I got more tangible next steps in the consult/results. I ended up using AI for that after. I put all of my vitamins and supplements into AI and it told me where I could implement changes after consulting my physicians.
Response from Function HealthAug 9, 2026
