Are there risks associated with using Zinc ?

Taking more than 150 milligrams of zinc per day for a long periods of time could lead to problems absorbing copper, lowered immunity, and lowered HDL (“good”) cholesterol levels. Zinc in amounts greater than 200 mg a day can cause nausea, vomiting, and diarrhea. There may be a link between excessive zinc consumption and Alzheimer's disease, but further study is needed. Zinc may decrease the effectiveness of some oral antibiotics prescribed for acne treatment, including tetracyline, doxycycline, and minocycline, especially when taken within two hours of these medications. Because long-term use of zinc inhibits copper absorption, it’s a very good idea to always take zinc and copper together. Most nutritionists recommend taking one milligram of copper for every 10 milligrams of zinc.
