  • Zinc is an important micronutrient which is essential for survival. Supplementation of zinc is essential for those who perform a strenuous physical activity because it gets excreted out through sweating.
  • Zinc has the antioxidant property that can strengthen body immune functioning, which prevents frequent illness and support optimal health.
  • Zinc plays an important role in the lumen and seminiferous tubules and also take part in different stages of spermatogenesis. Zinc maintains the balance between testosterone and prolactin hormone level in serum. Deficiency of Zinc leads to disruption of the testicles, impairment of the spermatogenesis which further causes poor semen parameters. However, increasing the dose of zinc is not very beneficial as excessive zinc intake provides a negative effect on sperm quality by reducing its motility and count.
  • Preclinical study data show that zinc supplementation increases serum testosterone level and that improves sexual ability by rising penile thrusting and delaying ejaculatory latency. This result indicates that zinc supplementation can be therapeutically used for sexual dysfunction.
  • Another clinical study report shows that zinc supplementation can improve sexual dysfunction in patients with chronic renal failure and undergo hemodialysis by enhancing serum testosterone and luteinizing hormone level.
  • From the clinical trial report, it has been estimated that marginally zinc-deficient normal elderly men can have an increased level of serum testosterone from 8.3 +/- 6.3 to 16.0 +/- 4.4 nmol/L (p = 0.02) by zinc supplementation within six months time period. This trial report concludes that zinc may play a significant role in shifting of serum testosterone levels in normal men.

Zinc supplementation supports serum IGF-I restoration, improve protein absorption and reduce age-related weakness and fatigue symptoms. 
  • Physical activities enhance the free radicals formation and accumulation of free radicals in the physiological compartments enhance the risk of illness. Zinc acts as a free radicals scavenger due to its antioxidant property and reduce the load of the free radicals and boost immunity for optimal health and improves performance.
