Copper is an essential trace mineral that is central to building strong tissue, maintaining blood volume, and producing energy in your cells. It helps form your baby’s heart, blood vessels, and skeletal and nervous systems. It also helps prevent anemia by regulating iron levels. Dietary insufficiency of copper during pregnancy can possibly leave the baby with problems, including cardiovascular disease, abnormal brain development, and impaired growth and development of the baby as a whole. Lack of adequate levels of copper is suspected to be a contributing factor in failed conception, miscarriage, and serious defects in the baby that affect the metabolism of connective tissue and the ability to produce energy.
