Sulfur is a mineral needed for the manufacture of many proteins, including
those forming hair, muscles, and skin. Sulfur contributes to fat digestion and
absorption, because it is needed to make bile acids. Sulfur is also a
constituent of bones, teeth, and collagen (the protein in connective tissue). As
a component of insulin, sulfur is needed to regulate blood sugar. Sulfur is
present in methylsulfonylmethane (MSM), a naturally-occurring substance
available as a supplement.
Who is likely to be deficient?
Deficiencies of sulfur have not been documented, although a protein-deficient diet could theoretically lead to a deficiency of sulfur. Low levels of cystine, and therefore possibly sulfur, 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 sulfur. Since most Western diets are high in protein, the majority of diets probably supply enough sulfur.
Are there any side effects or interactions?
No side effects have been reported with the use of sulfur.
At the time of writing, there were no well-known drug interactions with sulfur.
