IGF-1 Signaling Restoration

Meaning

IGF-1 signaling restoration refers to the clinical effort to re-establish optimal function of the Insulin-like Growth Factor 1 (IGF-1) signaling cascade, a critical pathway downstream of growth hormone (GH) action that mediates many of GH’s anabolic and tissue-repair effects. IGF-1 is predominantly produced in the liver and acts as a major regulator of cellular proliferation, differentiation, and metabolism. Age-related decline and certain chronic conditions can impair this signaling; therefore, restoration is key to promoting lean body mass, bone density, and metabolic health. This process is essential for maintaining a youthful endocrine environment.
