the body is present as a component of copper proteins. Unbound or inorganic copper produces
oxidative stress in the body, catalyzing highly reactive hydroxyl radicals (Toxicology. 2003 Jul 15;
189(1-2):147-63) A study of men residing in eastern Finland, an area with high levels of copper in
drinking water, established a positive correlation between serum copper levels and risk of acute
myocardial infarction (Salonen et al., 1991).
Cupric oxide is the rock known as malachite. Its major industrial uses include: a pigment for glass,
ceramics and porcelain glazes; in the manufacture of rayon; in sweetening petroleum gases; a
catalyst in ammonia manufacture; a wood-preserving agent; insecticide; fungicide; miticide;
molluscicide.
Centrum contains 2mg of cupric oxide, supposedly 100% of the RDA. And yet, Federal EPA drinking
water standards consider anything above 1.3 mg per Liter to be a health risk. According to the EPA
short term exposure amounts in excess of this standard can result in gastrointestinal distress, and
long term exposure can result in liver and kidney damage.
