When Most People Think of Copper Supplements, They Think of Their Graying Hair, But… Copper also helps support formation of bone, hemoglobin, and red blood cells. Red blood cells carry oxygen and nutrients throughout your body. Copper also works in balance with zinc and Vitamin C to form elastin. Elastin is a protein in your skin, which helps keep your skin flexible but tight. In addition, it can make protein more available to your body by freeing up iron, which is better utilized by the blood for other vital functions in the body. Copper is one of those underrated minerals that is definitely needed as we grow older, especially in the form of liquid concentrated.
