Moderate zinc deficiency may be relatively common in individuals with diabetes mellitus. Increased urinary zinc excretion appears to contribute to the marginal zinc nutritional status that has been observed in diabetics. More recently, supplementation of type 2 diabetics with 30 mg/
day of zinc for 6 months reduced a non-specific measure of oxidative stress (plasma TBARS). Studies indicate that Zinc supports a healthy immune system as well as improves glucose homeostasis. Zinc also exerts anti-oxidant effect especially on patients with diabetes who are subject to deleterious oxidative stress.
