Zinc is an essential trace element that is found predominantly in the musculoskeletal system, providing structural integrity and supporting catalytic functions for metalloenzymes such as superoxide dismutase and lactate dehydrogenase. Exercise, particularly endurance training, has been shown to reduce serum zinc levels in both male and female athletes relative to controls. Low dietary zinc reduces sports performance by reducing peak oxygen uptake, cardiorespiratory function and other variables, leading to reduced metabolic responses. Clinical studies show that zinc supplementation may support muscle function and physical performance. This mineral also plays critical roles in tissue repair and nutrient metabolism. By promoting healthy neutrophil and lymphocyte function, zinc promotes healthy immune function. Zinc citrate is a highly bioavailable form of zinc that supports a wide range of physiological functions.
