Copper ... Anemia or Low Iron Levels

Copper and iron work together in the synthesis of hemoglobin and red blood cells. According to studies, copper plays a part in the absorption of iron from the intestinal tract and it helps iron to be released into the liver which is where it is primarily stored. (9)
Iron from food sources, and supplements too, is used to create red blood cells. When copper deficiency occurs, iron levels fall too short and anemia can develop, which is a disorder is caused by iron deficiency. 
Anemia causes symptoms like fatigue, muscle aches, digestive problems, and impaired brain function. (10)

Healthy HairSkin, and Eyes

Adequate levels of copper are needed for the body to create the natural pigment and texture of the skin, hair, and eyes. Copper plays a part in the development of melanin, which is responsible for giving our skin its brown color as well as our hair and eyes their unique pigment.
In order for melanin to be created in the body, copper must be present to help create the enzyme called tyrosinase which allows melanin to develop.
Studies have also shown that copper helps build collagen, which is the substance responsible for maintaining skin’s youthful appearance and elasticity. Additionally copper is involved in the production of elastin, a substance found in the connective tissue of skin that keeps skin’s flexibility intact.
Copper keeps you looking younger as you age by acting as an antioxidant that protects your skin, hair, and eyes from free radical damage. Copper is needed for the utilization of the powerful antioxidant called Superoxide dismutase, which protects the body from oxidative stress and aging.
It’s also important for keeping hair from turning gray and thinning. As you can see, in many ways copper maintains the integrity of cells and tissues that are needed to keep elasticity, texture, resilience, and coloration of your outer organs
