I would like to be given a good discount so I can gift my children this membership. I think they would love it. I think this is what health is all about. A full spectrum of labs and then advice on how to obtain healthy levels. I think it would be great to put in your zip code and get a list of Function Health practitioners in your area.

Simone
Although I have my primary physician getting these results gave me a much more in depth analysis. Also providing me with recommended non prescription/supplement options to treat some of the results is extremely helpful and something I will implement before my next 6 month blood tests to see if they will have a beneficial/positive result. I would recommend function to everyone who might have some concerns and/or is getting up in age. I'm 57, still going through peri menopauae with some weird stuff going on. 😉

Failed to schedule my add-on tests on same day as my mid year tests, now I have to go back again

Thank you for bringing this to our attention. We understand how frustrating an extra lab visit can be. Your feedback is helping us identify opportunities to improve.
Debra C.
I was epecting the second lab round to be the same as the first. I wanted to see my vit D level, hormones, etc. which was not the case. So, when you say the membership includes another lab draw 6 months later I wanted to see a comparison of all that was tested the first time. As a result, I have cancelled my mbrship.

Function Health has been an excellent, seamless experience from start to finish. The platform is intuitive, the process is easy to navigate, and the information is presented in a way that’s both comprehensive and understandable. I especially appreciate how it provides a broad overview of my health and highlights biomarkers that may deserve closer attention. It has helped me become more informed and proactive about my health, making it easier to have meaningful conversations with my healthcare providers and make thoughtful lifestyle choices. Although all customer service is provided remotely, the support has been outstanding. The team has been responsive, professional, knowledgeable, and genuinely helpful whenever I’ve had questions. Overall, Function Health is a well-designed program that empowers people to take a more active role in their health. I highly recommend it to anyone looking for a convenient, informative, and user-friendly approach to understanding their health.

Lori
I love Function Health because I can get bloodwork that my regular doctor does not normally complete. I feel I get a very true picture of my current health due to the bloodwork that is routinely completed as well as optional blood tests that I can request.
