I've been through the most stressful time in my life, my husband passed away but I did manage to follow recommendations: avoiding allergies in food sources, taking multiple vitamins, Ferrin, and Omega fatty supplements. I've seen improvement in my results and plan to continue program to achieve optimized health.

What a great experience with Function from ordering the tests, scheduling, the lab draw and results were all seamless and easy. The results with clinical explanation were outstanding and easy to understand. What a great deal. I highly recommend for anyone concerned about their health or just wanting to get more in-depth labs on your body.

Rosa S.
I appreciate the information, especially being able to compare out of range findings at the six-month recheck. After two annual tests, I think I will take a break for a couple of years, but it’s a great resource to go back to.
