PCOS & IBS answers

Function is a blessing to my life. If I had Function earlier in my life, I would not have struggled with PCOS, IBS, and food sensitivities for as long as I did. I am SO excited to have this moving forward. I feel relieved, empowered, and inspired. Thank you Function team! ...

71 and going full force

Function has given me more insight into what's going on in my body. I'll be 71 on Monday and I'm going full force into taking control of my own health! I love knowing where I need to pay attention and where I'm doing pretty good. With the test results from Function, I believe my doctor will start to listen to me a little more closely. This can only be a good thing!

Gut Health

75 years old — but biologically 57

It's the next best thing to having Dr. Hyman as my personal physician. I have read his books and listened to his podcasts. I follow his recommendations for the most part, especially to heal my gut microbiome. That may be the reason my biological age is 18 years younger than my 75 years biological age. Yay! I just know that when I get retested in six months, anything now out of range will be perfect by following the recommendations given to me. Thank you. I am grateful.

A clear plan for heart health

I have felt unwell and didn't know where to turn but I needed some answers! Function Health is exactly what I needed! It has given me a look into what is going on in my body and empowered me to take the results to a doctor who would have probably not even ordered these tests and would have started being more invasive than necessary! This has made things so clear to me! I have a plan of action from Function Health’s suggestions and also have knowledge before walking into an appointment with a doctor. This may have saved me from a heart attack or stroke. I look forward to getting my numbers in the healthy range again and working on getting my metabolic age to keep going down!!! Now that’s just a fun challenge!! Worth every penny!

A deep dive into my health

It allows me to get labwork and do the deep dive myself as there are so few medical professionals that will run such a large amount of tests or even understand or believe in them. Function health allows me insight into my own health and what is improving it via labs.

A new positive attitude

I tell everyone about this program I mean it I do. It allows me to take control of my health and to have a good understanding of how and why. Never have I received information like this from my doctor never have I had anything explained to me in this form in this detail. I have already emailed my results to my primary. You are not only educating the patient. You are educating the doctors. I can’t say enough about this program. It has already changed my attitude toward my health. It has giving me a positive attitude and motivation to be better, I am 13.3 years younger than my chronological age And I’m going for 20 years younger!! Love all of you wonderful people!!
