IGF-1 - Insulin Like Growth Factor Binding Protein (IGFBP-3)

Your IGF 1 level is a pretty strong driver of cancer, so if you are at risk for cancer (family history) or a survivor of cancer.

Insulin-like growth factor binding protein 3 (IGFBP-3) functions as a binding protein for IGF-1. IGF-1 is primarily produced by the liver as an endocrine hormone and plays an influential role in virtually every system from muscle, bone, and connective tissue growth and repair, to the selective regulation of various aspects of metabolism, as well as helping maintain normal brain function and cardiac health.

Managing IGF-1 is done through diet.

It comes down to balance — too high, and you can ignite various disease states; too low and you can become frail from reduced bone mass, muscle mass, as well as diminished brain function.

"…for most adults, keeping IGF-1 below 175 ng/ml is likely important, and below 150 ng/ml should be even more protective. Serum IGF-1 levels below 80 ng/ml may be detrimental, especially after the age of 75."
