This is my second year with Function Health and I most enjoy the ability to text communication and receive a responses back aspect. They are willing to help. I love that this service is available online and gives me the ability to take some control over and monitor my own health through tests. I have suggested a benefit would be to provide a list of functional medicine doctors in each state.

Had enthusiastic expectations that function health would provide personalized insight. Unfortunatley the review was generic, did not provide personalized direction.
