Zinc is an essential trace mineral involved in over 300 enzymatic reactions and critical to immune function, testosterone production, wound healing, DNA synthesis, and cognitive function. It is one of the most common micronutrient deficiencies globally, particularly in men with poor dietary variety, heavy athletes who lose zinc in sweat, and vegetarians. Even mild zinc deficiency significantly reduces testosterone levels — supplementation in deficient men can increase testosterone 40-100%. Forms vary in bioavailability: bisglycinate and picolinate > citrate > gluconate > oxide.
