The scheduling and testing are very smooth and easy to do. Results start rolling in within a week and are generally all back to you within 4 weeks. Once the results are all in the clinician notes/summary follows within a day or two.

I love the data I'm seeing from function health, as I've made adjustments to my diet and to supplement areas where my diet isn't supplying enough of the vitamins and minerals I need. For example, because I don't eat meat, the blood test revealed that I needed to boost my iron intake (not getting enough from my food sources). Easy fix! And I love that it tells me that my body is 9 years younger than my actual age! (a gain of 3 years in lifespan after I made some suggested improvements).

I had a great experience with function health! I had some issues scheduling thru the AI chat, but once I reached a human, it was easy to schedule for the day and time I wanted. Blood draw went great! over all it was a good experience.
