"What are deficiency symptoms for copper?
Because copper is involved in many functions of the body, copper deficiency produces an extensive range of symptoms. These symptoms include iron deficiency anemia, ruptured blood vessels, osteoporosis, joint problems, brain disturbances, elevated LDL cholesterol and reduced HDL cholesterol levels, increased susceptibility to infections due to poor immune function, loss of pigment in the hair and skin, weakness, fatigue, breathing difficulties, skin sores, poor thyroid function, and irregular heart beat.
Despite the fact that most Americans consume less than recommended amounts of copper in their diet, these symptoms of copper deficiency are relatively rare. However, certain medical conditions including chronic diarrhea, celiac sprue, and Crohn's disease result in decreased absorption of copper and may increase the risk of developing a copper deficiency. In addition, copper requires sufficient stomach acid for absorption, so if you consume antacids regularly you may increase your risk of developing a copper deficiency. Inadequate copper status is also observed in children with low protein intake and in infants fed only cowï¿½s milk without supplemental copper."
does your zinc supplement contain any copper, for balancing purposes?
