More info please I would like more information about the supplements that I could or should add to correct some of the values that were out of range. I would like more information as to why those supplements are useful and the exact dosage that might be helpful. I also would like more information about why certain foods are on the avoid list instead of just the fact that I need to avoid them.

The reason I chose Function Health is all about the lab work that they do outside of the standard lab work done by primary care doctors. You find out more about what is going on in your body. They explain in detail all of the issues going on in your body and how to correct it. Function Health is the way to go if you want labs done above the ones you get from your doctor.

I’ve been wanting to do this for the longest time with a reputable company like Function. Function goes into so much more detail than modern medicine could ever give. I don’t mind paying what is really pennies to know what’s going on in my body.

I had the basic membership. It tested for over 100 different biomarkers. It pointed out I have a genetic problem with cholesterol that I would have never known without this test. I’m 37 and would recommend anyone in their mid 30s to have these tests down. The results came back in a couple days. I’m very pleased with Function. Hopefully it’s going to add a few years to my life!
