The comprehensive scope of testing and clarity of explanation of the results is excellent, including the clinician's notes after all results are in. Lots of good information for the money.

Anastasia
I am absolutely in love with functional health and their services. It’s my second year, and I will definitely stay with them. Lab visits easy to schedule /reschedule, everything is digital and easy; no need to communicate with anyone. Price is just great, number of bio markers is very good, better then pay insurance !

Brittney
This experience has empowered me! So much about how medicine operates feels like my health and information about my body are being gate kept from me. This service was not this way; it provided me with an affordable option to review my health. Scheduling was quick and convenient. Customer service was prompt and helpful. The results came in faster than expected and provided me with valuable insights, realistic goals, and a feeling of being seen. I feel comforted in knowing where I am at in my healthy journey and have gained answers to the cause of troubling symptoms. Best yet, I didn’t have to battle my insurance, be over charged, or convince a dr to run tests that are important to me. I definitely recommend!

I paid $300+ for an extended vitamins test that I never received. I tried to get a human but all I got was an AI bot that told me to keep waiting. It is impossible to get help. I'd be 100% happy to retract this if I receive the help I request, but I'm not holding my breath. Function Health "has" not contacted me as they state. Probably another AI chatbot.
