Zinc is a mineral that stimulates the activity of approximately 300 enzymes, which are substances that promote biochemical reactions in your body.1,2 These reactions are essential for the formation of superoxide dismutase, one of the body’s most important free radical scavengers. Zinc also promotes immune function,3-6 taste sensitivity,7-9 protein and DNA synthesis,1,10,11 insulin production,12,13 reproductive organ development and sperm motility.14-16 Zinc also supports normal growth and development during pregnancy, childhood, and adolescence.17-19 Maintaining adequate levels of zinc is equally important to aging adults.20-22 As people grow older, their immune function declines, partly due to the decreasing size and function of the thymus gland. Evidence suggests that zinc may help to maintain healthy function of the thymus gland in elderly people. 23 Scientists have also found evidence that a zinc deficiency in elderly adults may contribute to a decline in immune function with aging, or immunosenescence.24-26 These findings suggest that zinc plays a critical role in supporting healthy immune function with age. Zinc Lozenges provide premium-grade zinc as gluconate and oxide in a pleasant citrus-orange naturally flavored lozenge.
