The information that my husband and I get from Functions is so valuable. We have been with them for 2 years and have seen trends that give us actionable steps to improve our healthspan. I recommend to everyone I talk to.

Just had my six month blood draw, and I am making some progress! The brilliant thing is that the built in AI is helping me hyper focus on the most critical issues, and helped me build a new supplement protocol and dial it down for travel as well! I lov e this program and will continue with it to insure that my future labs continue on the best track possible!

I'm a huge fan of Function Health, in my second year of using it. The cost Is reasonable (it cost more when I joined and we all get the lower cost now). The report is thorough! All the info you need plus an AI chat to further explore. My only suggestion is to have all the extra tests on one page with check boxes so we don't have to view so many pages of extras.
