Repletion Information: Dietary sources rich in Zinc (per serving) are: Nutritional Supplements, Wheat Germ, Seeds, Nuts, Soybean Products, Legumes, Potatoes, Zinc-Fortified Cereal Products.

The 1989 RDA for zinc is 12-15 mg. In general, daily doses up to 50mg of elemental zinc appear safe.

Acute toxicity (nausea, vomiting, diarrhea, fever, muscle pain) may occur after intake of 1-2 grams of zinc. Chronic intakes of 150 mg of zinc for several months may impair certain immune responses, decrease high-density lipoprotein levels, or impair copper status (possibly leading to normocytic anemia).

Significant differences in tolerability between inorganic zinc salts and organic zinc chelates exist with organic chelates recommended for supplementation.
