Excess amounts of zinc may lead to a deficiency of:

The connection between excess zinc and a deficiency of copper is well-documented in nutritional science. Zinc and copper have a competitive relationship in the body because they utilize similar pathways for absorption. When there is an excessive intake of zinc, it can inhibit the absorption of copper in the intestines, leading to a decrease in the levels of copper in the body. This can result in a copper deficiency, which can have various health implications, including issues related to immune function, iron metabolism, and cardiovascular health.

Copper plays a crucial role in several physiological functions, including the formation of red blood cells and maintaining nerve and immune system health. Therefore, ensuring an appropriate balance of zinc and copper is essential for optimal health.

Magnesium, iron, and cobalt do not have the same direct inhibitory relationship with excessive zinc intake as copper does. While all of these minerals are important for various bodily functions, their absorption does not significantly interfere with zinc in the same manner, making copper the main mineral affected by excessive zinc consumption.
