  • Glutathione, an antioxidant
  • Heparin, an anticoagulant
  • Heparan sulfate, a viscous substance between the cells in the cartilage, skin and hair

The amount of sulfur you need per day is not known. No sulfur deficiency symptoms are known. The Recommended Dietary Allowance (RDA) for sulfur has not been set.

Foods High in Sulfur

Foods High in Sulfur

Picture 1. Examples of foods high in sulfur

You can get all the required sulfur from the sulfur-containing amino acids cysteine and methionine [1], cystine, homocystine, homocysteine and taurine. Other sources of dietary sulfur include vitamins B1 (thiamin) and B7 (biotin), methylsulfonylmethane (MSM), dimethyl sulfoxide (DMSO), inorganic sulfate in foods, drinking water and other beverages.

Sulfate Side Effects and Toxicity

Sulfur Burps

Some people may–after eating foods or supplements high in sulfur–experience ‘rotten eggs’ burps or/and gas due to hydrogen sulfide (H2S) produced by normal intestinal bacteria, when they break down sulfur compounds.

Diarrhea in Infants

Infants fed with formula containing water high in sulfur or people drinking water containing more than 250 mg sulfates per liter may get diarrhea [1].

Sulfite Sensitivity

Sulfites may cause an allergic-like reaction with facial flushing and swelling, difficulty breathing, skin rash and headache in sensitive people, especially in asthmatic patients [3].

Toxicity

There are no known symptoms of sulfur toxicity from dietary reasons. No Tolerable Upper Intake Level (UL) for sulfur has been set [1].
