Randy
Over all very good. But the summary of test results do not give a clear supplement plan to address any and all concerns. I used the chat box but it did not have access to my results either. I’m putting together on my own the proper supplements without input from function. Health which is why I chose function in the beginning.

I've been a Function member for a few months now, and it's completely changed how I think about my own health. Getting a full picture of my biomarkers — rather than waiting for something to go wrong — has been eye-opening. The lab work is comprehensive, the results are easy to understand even without a medical background, and the insights actually feel actionable instead of just a stack of numbers. What I appreciate most is that it doesn't feel like a one-size-fits-all approach. The recommendations are based on my data, and I've been able to track real changes over time. It's given me a level of awareness about my own body that I never had from a standard annual physical. If you've ever felt like you're guessing when it comes to your health, this is worth trying. Highly recommend.
