Copper is essential for both iron and zinc utilization, as well as for maintaining a strong cardiovascular system. Copper, along with iron, is necessary to produce hemoglobin (the part of the red blood cell that carries oxygen from the lungs to all the cells in the body). Copper is necessary for normal development and maintenance of blood, bone, nerves, connective and other tissues. Copper contributes to the structural integrity of connective tissue throughout the body. Collagen, the protein responsible for bone, skin, cartilage, and tendon elasticity, integrity, and strength, requires copper for proper reproduction. It is an important component of elastin (the connective tissue that gives elasticity to the blood vessels, lungs, and skin, allowing them to move and stretch with changes in pressure or movement). Easy on the stomach. Safe for all ages. No color or scent.
