Function Health gives me excellent and comprehensive health information. Based on this detailed analysis Function offers lifestyle, healthcare, diet, and supplement recommendations. I have followed these recommendations and have improved notice significant improvement in the quality of my health indicators (at the 6 months retest) and my overall sense of well being. I fully recommend Function Health.

I will definitely do this again next year, it picked up many things that a normal visit to a Doctor does not. Insurance pays for blood tests and always sides on the minimal amount. I picked things up that I have worked hard to address. I am a veterinarian and own a large veterinary hospital and the service is incredible. They made me feel like I am their client.

great communication, great web experience
By Jonathan R.
Very thorough markers being tested that are not routinely tested for in traditional medical practices. Also, the price is very reasonable compared to other bloodwork pricing.

This is a great way to advocate for your own health. The tests they run give an inclusive overview, as well as your biological age. This testing should be the norm in medical care!

Easy and so informative! If you’re not a doctor person, this the way to go. Also if you like to research and learn. I highly recommend this service!
