Real testimonials from actual members
“Love love love having this service available! It is exactly what I’ve been looking for for many years as traditional western medicine is loathe to do any preventative testing besides the basic annual Chem/CBC. I love being able to take charge and be proactive in my health. Keep up the good work! You have my membership for life!.”
“This is a GREAT resource, I am a professor at UCSF in the medical school and do research on chronic disease prevention... yet I can’t get all of the blood biomarkers I want measured on my own body through my primary care doctor.”
“Function Health has allowed me to set a baseline from which I can monitor & take control of my health. My Function dashboard provides guidance on how to improve my results. All of my health information is one convenient & easy to comprehend location. I can even download my records, should I need to see a doctor for any reason.”
