Copper is a mineral that is involved in many critical functions, including the formation of red blood cells, the absorption and utilization of iron, and in respiration, brain function, and hormone and antioxidant activities. Although the body has only a tiny amount of copper, it is important if you are taking zinc supplements, as zinc inhibits absorption of copper. People who take zinc supplements may be deficient in this critical mineral, which is found in high levels in the prostate, or they may have BPH or prostatitis, both of which are characterized by low zinc levels. Therefore, a copper supplement should be takento ensure the body gets enough because it competes with zinc for absorption and utilization in the body. A healthy balance of zinc and copper is about a 10:1 ratio.
In addition to failing to balance copper intake with zinc intake, a copper deficiency can be caused by high consumption of vitamin C or iron, both of which decrease copper absorption. If you are older than 60, you may have an inadequate amount of stomach acid, which hinders the body’s ability to absorb minerals like copper and zinc. A copper deficiency is characterized by fatigue, skin sores, slow wound healing, hair loss, diarrhea, and edema.
The RDA for copper in men is 900 micrograms daily. Copper is found in significant amounts in crimini mushrooms, sesame seeds, and a wide variety of leafy greens (e.g., Swiss chard, turnip greens, kale, spinach, mustard greens).
