Expanding the labs would be helpful so I do not have to drive 1000 miles, but the information is verry helpful and insightful. I think that last years insights were more helpful than this year.

I have never received such a comprehensive and insightful set of lab results before. Function Health provided an exceptional level of detail that allowed me to truly understand my overall health. In contrast, my past experiences with traditional medical care have often felt incomplete—tests are limited, and feedback is usually summarized with “you’re within normal parameters,” without any guidance on how to improve or optimize my results. Function Health not only revealed areas that needed attention but also empowered me with actionable information to take charge of my well-being. I’m sincerely grateful for the clarity and care they provide.

I have done my first 6 month lab testing but I was very impressed with the tests run. The detailed intake on supplements and scripts I take right now I felt was integral to providing me with a thorough diagnosis/suggestions on where I could improve. Just loved I was 7 years younger than my actual age. It encouraged me that I am on the right path with my wellness approach!

As a woman and a nurse, I feel Function Health services are exactly what I needed especially since I am over 60 and want to have control over my health and wellness as I age. This platform fits perfectly with my active lifestyle.

I appreciate and value Function Health. I am seeing results from the guidance on food and supplements, and gaining insight into my biomarkers and other labs. I share these with my primary care provider to further optimize my health and well-being.

I love the in depth explanations on how to improve any of the markers that are out of range

I was excited to do the Function Health after following Dr Hyman for years and having started taking control of my own health. It was fast and easy and the date has helped me tweak a few changes to my diet but also advised me I am 10 years younger than my chronological age. How awesome is that.
