Insulin is a protein-based hormone rich in sulfur-containing amino acids. The detoxifying compound glutathione is also a sulfur-containing compound, where sulfur, as cysteine, is beneficial for liver disorders. Taurine is a component of bile acid. As part of taurine, sulphur aids in digestion. As a part of methionine and cysteine, it helps in the metabolism of homocysteine. Although there is no official RDA for sulfur, it is a critical nutrient. Daily intake is usually 800 to 900 mg of sulfur per day.
Certain health conditions, such as arthritis and liver disorders, may be improved by increasing the intake of sulfur to 1,500 mg per day in supplemental form (most commonly as methylsulfonylmethane or MSM). Sulfur-rich foods include eggs, legumes, whole grains, garlic, onions, brussel sprouts, and cabbage.
