Sulphur is a mineral needed for the manufacture of many proteins, including those forming hair, muscles, and skin. Sulphur contributes to fat digestion and absorption, because it is needed to make bile acids. Sulphur is also a constituent of bones, teeth, and collagen (the protein in connective tissue). As a component of insulin, sulphur is needed to regulate blood sugar. Sulphur is present in methylsulfonylmethane (MSM), a naturally-occurring substance available as a supplement. Where is it found?Most dietary sulphur is consumed as part of certain amino acids in protein-rich foods. Meat and poultry, organ meats, fish, eggs, beans, and dairy products are all good sources of sulphur-containing amino acids. Sulphur also occurs in garlic and onions and may be partially responsible for the health benefits associated with these items.1 Most of the body’s sulphur is found in the sulphur-containing amino acids methionine, cysteine, and cysteine. Vitamin B1, biotin, and pantothenic acid contain small amounts of sulphur. Who is likely to be deficient?Deficiencies of sulphur have not been documented, although a protein-deficient diet could theoretically lead to a deficiency of sulphur. Low levels of cystine, and therefore possibly sulphur, were reported many years ago in people with arthritis, but this association is far from proven.2 How much is usually taken?No recommended intake levels have been established for sulphur. Since most Western diets are high in protein, the majority of diets probably supply enough sulphur. Are there any side effects or interactions?No side effects have been reported with the use of sulphur. References1. Augusti KT.
