Copper is an important trace mineral for enzymes involved in the formation of red blood cells and connective tissue proteins. Copper increases with inflammatory conditions and estrogen supplementation. It may be low with low serum protein and malnutrition without necessarily reflecting inadequate liver copper stores. Some signs of copper deficiency include certain types of anemia, low white blood cell count, osteoporosis, and impaired immune system response.
