The reason I chose Function Health is all about the lab work that they do outside of the standard lab work done by primary care doctors. You find out more about what is going on in your body. They explain in detail all of the issues going on in your body and how to correct it. Function Health is the way to go if you want labs done above the ones you get from your doctor.

I’ve been wanting to do this for the longest time with a reputable company like Function. Function goes into so much more detail than modern medicine could ever give. I don’t mind paying what is really pennies to know what’s going on in my body.

I had the basic membership. It tested for over 100 different biomarkers. It pointed out I have a genetic problem with cholesterol that I would have never known without this test. I’m 37 and would recommend anyone in their mid 30s to have these tests down. The results came back in a couple days. I’m very pleased with Function. Hopefully it’s going to add a few years to my life!

Function Health made it easy to get started, tied in nicely with Quest Diagnostics' availability and everything was in order showing up to my appointment for the blood draw. Results came in a reasonable amount of time and were nicely laid out in an easy-to-read format. I am so happy my wife recommended this service to me.

FAR exceeded my expectations! I would highly recommend, and have, to all my friends and family members who are conscious of their health. Far more labs than I expected and at a great price! Excellent explanation of results and list of top supplements and foods really helped me know what I was getting right and where I need to step it up. I now know exactly what I need to focus on and the AI chat is great for basic info. and takes my personal history, current diet and supplement into account when answering questions. LOVE IT!
