Introduction
Zinc is an essential trace mineral that plays a vital role in numerous physiological processes throughout the body. It is crucial for immune function, wound healing, DNA synthesis, and cell division. Perhaps most notably, zinc is integral to hormonal health, where it supports the production and regulation of key anabolic and reproductive hormones.
One of zinc’s more specific roles involves its influence on Insulin-like Growth Factor 1 (IGF-1)—a hormone similar in structure to insulin that plays a significant role in growth and anabolic processes such as muscle repair and regeneration. Adequate zinc levels have been associated with increased IGF-1 activity, which may enhance muscle development, recovery, and overall physical performance.
Zinc is also well-documented for its impact on serum testosterone levels, particularly in men. Research indicates that zinc deficiency can lead to a noticeable decline in testosterone, while supplementation may help restore or elevate levels, especially in those with suboptimal zinc status. By supporting both IGF-1 and testosterone, zinc plays a dual role in promoting anabolic activity, reproductive health, and overall vitality.

Zinc Supplementation
The recommended daily intake of zinc is 11mg, but athletes, bodybuilders and those with deficiencies may require slightly higher amounts.
Aim for 10-30mg daily from food & supplements combined and avoid over supplementation.
