I got informative results that helped me improve my health. For example found out I was deficient in some vitamins, positive for anutomimmunity and eventually found that I have high heavy metals. I was able to course correct before any heath issue got out of hand.

Function is responsive to the needs of its customers and the information is comprehensive and easy to understand.

It’s given me valuable insight into my personal health markers, and by making changes to my diet, supplements, and lifestyle, I’ve already seen great results. My only complaint is that referring friends and family to Function Health to get the $100 off their annual membership can be a bit tricky — I can’t recall all the details, but it had something to do with taxes, which makes the process more complicated than it should be.

I really love you program and how it has helped me. I try to refer people when I can. I think that the report created after all the lab testing is helpful and I want people to know that this try of screening is possible. I would like to see more promotional deals because I think that the price is just a little out of the price range for most people but it is so valuable and has helped me. I would like to continue being a member because I want to see improvements in my health and that happened because of this company.

I love being in charge of my own health --feel like I can actually converse with my primary and cant be pushed around!

Still no ability to get advice without going through an Functional docs extensive onboard process not to mention expensive.
