IGF-1 (Insulin-like Growth Factor 1) is produced by the liver in response to growth hormone and mediates many of its effects on muscle, bone, and tissue repair. It is a key biomarker in longevity research — both deficiency and excess are associated with health risks. Low levels may indicate growth hormone deficiency, malnutrition, or liver disease. Elevated levels have been associated with certain cancer risks. Optimal levels support lean body mass, bone density, and cognitive function.
