What it is

Copper gluconate is a mineral supplement that provides copper, an essential nutrient. It is formed by combining copper with gluconic acid, which is derived from glucose. This process results in a stable, water-soluble salt.

Why it's used

Manufacturers add copper gluconate to foods as a nutrient supplement, fortifying them with essential copper. It is often found in energy bars, nutritional supplements, and some processed foods where added vitamins and minerals are desired.

Health notes

In the US, copper gluconate is generally recognized as safe (GRAS) by the FDA when used as a nutrient supplement. Copper is essential for many bodily functions, including energy production and iron metabolism. JECFA has evaluated copper compounds and established acceptable daily intakes. While copper is vital, excessive intake can lead to adverse effects. Evidence on the long-term effects of supplemental copper at typical intake levels is generally reassuring, but high doses should be avoided.

Allergen info

Copper gluconate is not derived from any of the nine FDA major allergens. It does not contain gluten.
