Zinc facts include:

• essential for manufacturing proteins and nucleic acids (DNA - genetic material of cells)

• involved in action of insulin in utilization of carbohydrates

Basically non-toxic, however prolonged high doses (2+ g/day) have produced zinc side effects; some prolonged doses over 100 mg/day reduced HDL cholesterol and increased LDL cholesterol – normally you want to do the reverse of this – increase the good cholesterol (HDL) and reduce the bad cholesterol (LDL).
