Also known simply as copper, this mineral is an important trace element for human nutrition. The body needs copper to absorb and utilize iron, and copper is also a component of the powerful antioxidant enzyme superoxide dismutase. Copper supplements have been shown to increase superoxide dismutase levels in humans (Source: Healthnotes Review of Complementary and Integrative Medicine, www.healthnotes.com). The synthesis of collagen and elastin is in part related to the presence of copper in the body. Copper is also important for many other processes; for example, there is research showing that copper is effective for wound healing and for antiaging due to its inhibitory effect on matrix metalloproteinases and stimulation of fibroblasts that build healthy collagen (Sources: Cellular and Molecular Life Sciences, March 2010, Epublication; Connective Tissue Research, January 2010, Epublication; Archives of Dermatologic Research, April 2009, pages 301–306; and Biomedical Research on Trace Elements, 2005, volume 16, number 4, pages 302–305).
