Swanson Albion Chelated Magnesium delivers mineral support for healthy muscles, nerves, bones and more. Magnesium also offers cardiovascular support and promotes healthy blood pressure levels. Each capsule contains 133 mg of Albion® amino acid chelated magnesium. What Makes Chelated Mineral Glycinates So Superior? 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 & absorbed across the intestinal wall, and Albion's glycinate chelates are small enough to transport right into the cells!
