Insulin-Like Growth Factor 1

Meaning

Insulin-Like Growth Factor 1 (IGF-1) is a peptide hormone that plays a major role in mediating the anabolic effects of Growth Hormone (GH), particularly regarding tissue growth and repair. This factor circulates systemically, primarily synthesized by the liver in response to GH stimulation, and acts as a potent mitogen. Maintaining optimal IGF-1 levels is essential for cellular proliferation, differentiation, and overall musculoskeletal health in both pediatric and adult populations. It is a key biomarker of the anabolic state.
