What it is

Cupric oxide is a compound made of copper and oxygen. It is often produced by heating copper metal in the air. It appears as a black powder.

Why it's used

Cupric oxide is used as a source of copper in dietary supplements and fortified foods. It can also be used as a colorant in some applications, though this is less common in food.

Health notes

In the US, cupric oxide is generally recognized as safe (GRAS) for use as a nutrient supplement. The FDA has approved its use in certain food categories. JECFA has evaluated copper compounds and established acceptable daily intakes for copper. While copper is an essential nutrient, excessive intake can lead to adverse health effects, though this is unlikely from typical food consumption.
