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.

My husband and I chose to purchase two add-on tests but it wasn't clear that those tests would require two blood draws in addition to the basic draws. We live an hour away from a Quest lab, so this was an inconvenient surprise. The add-on tests are scheduled separately from the standard test but this feature wasn't visible on the website, kind of tricky. Had to involve support

Six month blood draw time!
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
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.
Response from Function HealthJul 30, 2026
Thank you for your thoughtful review, Shoshanna! We're so glad to hear you're enjoying your second year with Function and that you've found the reports and AI chat helpful. We also appreciate your suggestion about having the add-on tests on a single page—feedback like yours helps us continue improving the member experience. Thanks for being a part of Function Health!

Customer service is extremely slow
Customer service is extremely slow. They didn’t book the first two blood draws were supposed to be booked at once. Never happened and no way to rebook. Also did the draw in AZ to avoid a $248 fee and now I have to try and do the second one in NJ and telling me I have to pay that fee. That’s false advertising. It increases your price by 65%. Seriously thinking about doing a chargeback on credit card for this disaster and the very very slow response plus the fact you can’t talk to anyone. Also would be very vocal on social media negatively if this doesn’t get resolved soon
