Very thorough and complete. Gave me a good list of supplements to take. I love knowing how my body is doing from the inside out....

Excellent and great organization. Have high cholesterol but zero atherosclerosis so my biological age probably isn’t correct. All good. Worth the money for sure.

When I first signed up with function health I wasn’t sure what to expect. I’m glad I did cause it really gave a great insight to what’s going on inside my body. Many things I already knew because of functional medicine practitioner but I learned some things too.I really loved that I had flexibility to when I could get tested. I had to change my testing dates a couple of times but I was able to do it with ease. If you want a deeper look into your health I definitely recommend this. I do wish the additional test were less expensive but other than that it is great!

Function Health helped me to discover that my A1C and LDL were creeping upward and gave me actionable advice on how to lower them with both food choices as well as supplements. Both have been improving! I love being able to easily add on tests that I’d like, or are recommended.

Function Health is a tremendous way to understand your body’s weaknesses and strengths. The blood work is comprehensive and gives their clinicians and you a way to manage your health that is not really normally done with a PCP. I will use Function Health every year.
