Overall, an easy and comprehensive way to gather health information that actually makes sense (or makes it easier to find answers to the things I didn't understand!). My questions were answered quickly and were very helpful. All in all, a great experience.

Chris
I am a huge supporter of Dr. Hyman's holistic approach to wellness and longevity and his Function Health platform. The ability to measure and track over 102 biomarkers is effortless, cost effective and sometimes life-saving! I have recommended Function Health to many family and friends. I am impressed with the entire process and look forward to continuing my health and wellness journey! With my biological age over 10 years younger than my birth age I can confidently say my daily habits, lifestyle choices and high quality supplements are definitely working!

It is very helpful to know what your body is doing. You have questions like why am I tired a lot of the time. I also could tell my brain wasn't working as well as it should.

Victoria T.
Function Health allows me to track my health over time through nearby labs and detailed tests( some of which my healthcare company does not provide nor recognize as necessary like lipid participle size or MTHFR.)The summary reports detail what needs improvement and what has improved. Some helpful nutritional support such as foods to consume is provided. I am very pleased with this service.
