　　When the human body is deficient in copper, the pigment oxidase in brain cells decreases and the vitality decreases, causing memory loss, confusion, slow reaction, unstable gait, and movement disorders.

　　In addition, the production of elastin and collagen in the cardiovascular system depends on the catalysis and activation of copper ions. Long-term copper deficiency in the human body will cause arteriosclerosis, leading to coronary heart disease occurrence. Copper is also a coenzyme of lysine oxidase, which promotes the connection of collagen fibers. When there is a lack of copper in the body, the catalytic effect of lysine oxidase is greatly weakened, and the collagen fibers are incompletely cross-linked, resulting in tooth loss, weak legs and feet, and weak muscles and bones.
