What is IGF-1 (Insulin-like Growth Factor 1)? Optimal Ranges & Function

Normal Range:50-350 ng/mL

Optimal Range:100-180 ng/mL

What is IGF-1 (Insulin-like Growth Factor 1)?

A hormone similar in structure to insulin that plays a key role in growth and development. Produced mainly by the liver in response to growth hormone stimulation.

Why IGF-1 (Insulin-like Growth Factor 1) Matters

IGF-1 is a double-edged sword for longevity. While essential for muscle maintenance and tissue repair, chronically elevated levels are associated with accelerated aging and increased cancer risk. Centenarian studies show moderately lower IGF-1 correlates with extended lifespan.
