SULFUR (S)
Sulfur is generally considered to be the 8th or 9th most abundant mineral in the human body. It is stored in every cell in the body, with the highest concentrations being in the joints, hair, skin, and nails. Sulfur is also the least researched major mineral.
As part of four amino acids, sulfur performs a number of functions in enzyme reactions and protein synthesis. It is necessary for formation of collagen, the protein found in connective tissue in our bodies. Sulfur is also present in keratin, which is necessary for the maintenance of the skin, hair, and nails, helping to give strength, shape, and hardness to these protein tissues. Sulfur, as cystine and methionine, is part of other important body chemicals: insulin, which helps regulate carbohydrate metabolism, and heparin, an anticoagulant. Taurine is found in bile acids, used in digestion. The sulfur-containing amino acids help form other substances as well, such as biotin, coenzyme A, lipoic acid, and glutathione. The mucopoly-saccharides may contain chondroitin sulfate, which is important to joint tissues.
Sulfur is important to cellular respiration, as it is needed in the oxidation-reduction reactions that help the cells utilize oxygen, which aids brain function and all cell activity. These reactions are dependent on cysteine, which also helps the liver produce bile secretions and eliminate other toxins. L-cysteine is thought to generally help body detoxification mechanisms through the tripeptide compound, glutathione.
