Sulfur is a somewhat “forgotten” nutrient you don’t hear mentioned very often, but it’s very important for optimal body function and health. You get most of your sulfur from certain proteins in your diet, specifically the amino acids methionine, cysteine, cystine, homocysteine, homocystine and taurine.(1)
Of these, the two most important sources are methionine and cysteine. Methionine is an essential amino acid, which means it cannot be synthesized by your body and must be supplied through your diet. Cysteine is conditionally essential, because it can be synthesized from methionine but not from inorganic forms of sulfur.(2)
