Copper (gluconate) is an essential mineral that is found in a range of foods and supplements. It is very important that humans have a regular intake of this mineral, as it is essential to help the body use iron, which in turn is crucial for growth and development. Copper also plays a part in aspects such as nerve function, bone density and how your body processes sugar.
Foods that contain copper include “organ” meats (liver, kidneys), certain shellfish such as oysters, nuts, seeds, leafy greens and dark chocolate.
