Mama
I have been a member of Function Health for three years plus. It has helped me in many many ways. About six months ago when I had my labs done my biological age had increased seven years in a seven month span. really really scared me. made me dive deep into what was going on. Function Health helped me to find ways to improve my health and what to ask my doctor for. last month, I had my labs done, and my biological age went right back to where it was, which means I fixed my problem. I could not have done that with normal labs doctors would prescribe to me. I am so thankful I have Function Health.

Mary B.
I would recommend Function Health to everyone. The blood work is extremely thorough. The follow up Clinician notes are very detailed and very helpful in understanding the biomarker numbers. The price is very reasonable. The phlebotomist at Quest Diagnostics said the test requested would cost several thousand dollars. She said most doctors would never request this detailed bloodwork unless the patient had an issue. I want to prevent medical issues by catching things early. This bloodwork is one tool to help.
