This is my second year using FunctionHealth and I love it! I have been recommending everyone I know to use it, I have already learned a lot about what I needed to adjust in my life to get healthier, and I noticed a difference in my second year!

I love the amount of blood tests I get for my money. The value is amazing. The clinician’s notes are thorough and quick. A lot of extra notes explaining what it all means and the recommendations for diet and supplements are very helpful.

I signed up for Function because my primary care couldn’t order the labs I needed for working with my integrative medicine provider. It gave me more that I was expecting and for a cheaper price! I really appreciated the AI function to develop protocols. I like that there are actions to take, not just results with nothing to do about it.
