I feel empowered to take control of my health for the first time in my life.
Worth every penny because you actually get valuable and actionable information on your health.
I'm a Dietitian and love this as an option for my clients wanting a more preventive approach to health. It's also helped me learn more about my own health and areas that need more attention.
I've found Function to be the most valuable tool in my health toolbox. For the first time, I finally feel in control over my own health with access to labs and results on my own terms, not the doctors'. I can't recommend Function enough.
