If you want to take control of your health do blood work with Function Health! The panel(s) they offer is far more thorough than any yearly blood work the typical doctor does. It is so insightful and helpful for making changes in your lifestyle to address issues that the results convey. The food and supplement suggestions they make, given your particular results, are easy to follow. Customer service is responsive and helpful. Very communicative and easy to navigate their website and app.

It's very helpful to finally know what areas I may need to improve on, and what area's I'm doing well on. My medical plan does routine blood work, but I wanted to dig deeper so I can enjoy my life to the max!

I received immediate replies to my questions and it appeared that they were written by "real" people. When there were delays in test results I was advised when to anticipate receiving them. It was a smooth and direct transaction for me without having to repeat myself numerous times to a BOT. Results and recommendations were helpful.

Testing and reading results were so easy! My doctor took one look at my results and knew what my diagnosis was. Many people spend years of searching with different specialists but I did Function health and was diagnosed in no time.
