It was so nice that they checked into so many different things that my normal doctor wouldn't do and I got some good insights that I had never known before.

Denise
I found out that even though I thought I was doing pretty well with my diet, that my hsCRP was high. My hsCRP had never been tested with mainstream medicine. A big cause of high hsCRP is seed oil (it hides in so many products!!) and now I'm working on cutting out seed oils.

The whole process has been very simple and not complicated. The clear and detailed feedback on the lab bio markers has been extremely informative and helpful in me making some diet and supplement changes. Just received the clinician feedback and I really like the way the feedback ties in my whole health status and not individual labs in isolation.

I really love what Function Health is doing to empower people to stay on top of their health, instead of monitor conditions like traditional healthcare. It's an extremely reasonable investment in my future health and I feel in charge of my healthcare. The platform is always growing and it's just so easy to stay on top of. I've been with function for 4 years and see no reason to stop.

Michael D.
Unhappy as I was completely scammed by Function Health. I purchased a full retest of all biomarkers and received only a small number that were actually done. I was told that their description was inaccurate, which amounts to false advertising. I am done with Function Health.
