Zinc supports your body's natural immune defenses. Research demonstrates that zinc deficiency is widespread, especially in the elderly.1-4 This deficiency may contribute to aging-related impairment of immune function-or immunosenescence.1,3 Scientists found that zinc supplementation offers an effective way to support aging immune systems, as well as healthy inflammatory and antioxidant responses.1,4-6

A longstanding problem is that zinc absorption can be limited1 and certain molecules in plant sources and grains can further inhibit absorption.7 Beyond immune support, zinc plays other crucial roles. It is an essential component of superoxide dismutase, one of your body's most powerful natural antioxidants.8 Zinc stimulates the activity of about 300 enzymes that promote biochemical reactions in your body.9 This key mineral is also an integral component of vital hormones and supports protein and DNA synthesis, insulin production, as well as thyroid and bone metabolism.7,8-11

Zinc supports cardiovascular and neurological health, and helps maintain vision in the elderly.8,9,12 Age-related immune decline is partly due to the decreasing size and function of the thymus gland. Evidence suggests that zinc may help maintain healthy function of the thymus gland in elderly people.1 OptiZinc® is a superior bioavailable form of zinc.13 It is assimilated more easily than ordinary zinc because it is comprised of one of the most absorbable forms of zinc - zinc methionate (methionine).14 Published studies show that it results in higher blood levels compared to other forms of zinc.14
