Copper is an essential trace element that is vital to the health of all living things (humans, plants, animals, and microorganisms). In humans, copper is essential to the proper functioning of organs and metabolic processes. The human body has complex homeostatic mechanisms that attempt to ensure a constant supply of available copper while eliminating excess copper whenever this occurs. However, like all essential elements and nutrients, too much or too little nutritionalingestion of copper can result in a corresponding condition of copper excess or deficiency in the body, each of which has its own unique set of adverse health effects. Copper stimulates the immune system to fight infections, repair injured tissues, and to promote healing. Copper also helps to neutralize “free-radicals“, which can cause severe damage to cells.
