    Copper

    With meals

    Copper is an essential trace mineral that the body requires in small amounts for numerous enzymatic reactions. It is naturally abundant in organ meats, shellfish, nuts, seeds, and dark chocolate. Copper plays critical roles in energy production, iron transport, and the formation of connective tissues including collagen and elastin.
