I liked getting the reminder to do the bloodwork, the ease of making the appointment and that Quest is close to where I live.

Gale
The detail is amazing and very comforting. It does validate my GP. However gives me recommendations he did not. It gives better clarity and focus on issues I need to address immediately. And now I do not wait an entire year to visit him to see how I am doing. I can get a Function update instead. The price is highly reasonable. I highly recommend this to anyone who wants more details with food and supplement recommendations tailored for you based on your Biomarkers.

I've been taking various supplements over the years but didn't truly know what was working or what I really needed until I signed up for Function Health. When I received the lab results back in January I discovered a lot of positive news about my health alongside a few markers that needed my attention. Such as low ferritin levels which I wouldn't have guessed in a million years. And that I've been actually over supplementing in Vitamin D. Now I just completed my second mid year test and are very happy to report that all of my negative markers are moving in a positive direction and have a much clearer picture of my overall health and which supplements, diet and lifestyle habits I need to focus on. Thank you to Mark Hyman and rest of the team that created this service for anyyone seeking an indepth analysis of their health at a very affordable price. I am very greatful for this insight into my health and highly recommend Function Health to all of my friends and family.
