The reports are clear, easy to read and the clinician notes where helpful and honestly more comprehensive than I used to get from my family doctor.

Tracking health markers over time has been awesome. I appreciate Function Health’s affordability and the flexibility to test without a physical and doctor involvement. I have specific areas for improvement that I can easily assess from within the app. I’ve referred three friends to Function as well and they’re loving it. Would highly recommend!

I have been a Function client for 3 yrs and it has greatly helped me and my husband improve my health. They are constantly improving their website, testing process and streamlining the amount of vials for annual testing. Also adding additional testing for those with specific needs. During the three years I have had numerous questions and the customer service has been awesome. My husband and I both get the testing and it is the best investment in our health. We are in our 70s.

I am really impressed with the ease and thoroughness of Function. There were so many companies to choose from and I feel like I chose the best one. Having clinical notes to understand with all the results mean and how to make changes is invaluable. I love having control over my own health and to have Function as a partner in this pursuit.

Function health is an overall good service with a poorly structured set of labs and insane prices for add-ons.
