Supplemental zinc can inhibit the absorption and availability of iron and copper. If more than 50 mg of supplemental zinc is taken daily, 2 mg of supplemental copper should also be taken to prevent deficiency. Calcium in combination with phytic acid reduces zinc absorption. Chronic ingestion of more than 300 mg of zinc daily may be toxic. Zinc should not be used in mega-amounts. A study showed that if 300 mg per day were ingested, white cell function of the immune system could be impaired.132 Also, copper should be supplemented while using doses of zinc over the recommended intakes.333

Zinc: Promoting immune function and more

Zinc is a mineral that stimulates the activity of approximately 100 enzymes, which are substances that promote biochemical reactions in your body. 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,112-115 taste sensitivity,116-119 protein and DNA synthesis,120-122 insulin production,123,124 reproductive organ development and sperm motility.125-127 Zinc also supports normal growth and development during pregnancy, childhood, and adolescence.128-130

Zinc deficiency and the need for zinc supplements

Age-related declines in immune function are associated with zinc deficiency, and the elderly represent a group that is vulnerable to mild zinc deficiency. Certain aspects of immune function in the elderly have been found to improve with zinc supplementation.112-114,116,131

OptiZinc® is a superior bioavailable form of zinc.135
