Swanson Albion® Copper is a highly absorbable form of this trace mineral that is used by the body in multiple enzymatic body processes, including the production of hemoglobin—a protein that promotes tissue oxygenation and thereby energy throughout the body—as well as heart muscle contraction and blood vessel function. It is needed for healthy cell membranes and connective tissues, nervous system function and bone growth. Like other Swanson Albion chelated minerals, our copper capsules feature Albion's patented glycinate chelate form to provide for maximum assimilation. For more information on Albion products, see www.albionminerals.com. What Makes Chelated Mineral Glycinates So Superior? First we need to understand the chelation process. Chelation is the result of minerals becoming chemically bound to amino acids in a very specific manner. Chelation occurs during the digestive process to facilitate transport of minerals across the intestinal wall so that they may be utilized throughout the body. Amino acids are not the only "chelators" available, but they are ideal for minerals. The body is very efficient at absorbing individual amino acids, and Albion has identified the amino acid glycine as the preferred molecule for creating organic chelated minerals. Glycine is readily identified and absorbed across the intestinal wall, and Albion's glycinate chelates are actually small enough to transport right into the cells themselves!
