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-

Dosage and Use
Take one capsule, one to three times daily with or without food, or as recommended by a healthcare practitioner.
The number of capsules you take will depend on the amount of zinc in other products you are taking.
Most people's intake of zinc should not exceed 90 mg a day.
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.133
