Process was so easy and was so worth it. I learned so much more about my health than I do with the normal labs. The follow up clinician notes are very helpful and provide action items. Definitely would recommend.

Function Health is a great addition to our health routine that helps us quantify the results of changes we make to what we consume and our activity level. Very helpful to see the changes twice a year. I appreciate the summary of recommendations so much. Testing with guidance is invaluable. Highly recommend.
