I am so grateful to have found function health. It has changed my life. I am now making changes so that I can be around for a long time for my kids. I added the Lyme panel and now have the answers I have been looking for. So grateful!!!

I'm glad to have this thorough baseline information about my overall health and markers to watch from year to year. It's much more comprehensive than the blood panels my doctor does, and the physician notes are super valuable for giving action items or foods to focus on adding in or eliminating specific to my individual needs.

The whole service is amazing. I love the app and was glued to every update from my bloodwork. I am a healthy 55 year old woman, but I found some concerning inflammation and other lipids that are prompting me to get a heart CT scan. The clinical notes were incredibly detailed and helpful.
