NameCystine
Groups
  • nutraceutical
  • approved
DescriptionA covalently linked dimeric nonessential amino acid formed by the oxidation of cysteine. Two molecules of cysteine are joined together by a disulfide bridge to form cystine.
Synonyms
  • L-Cystine
  • β,β'-dithiodialanine
  • Cistina
  • (R,R)-3,3'-dithiobis(2-aminopropanoic acid)
  • L-alpha-Diamino-beta-dithiolactic acid
Brand Names
  • Distilpure Msm
  • Medi Msm (methyl Sulfonyl Methane)
  • Amino-cerv
IndicationIt has been claimed that L-cysteine has anti-inflammatory properties, that it can protect against various toxins, and that it might be helpful in osteoarthritis and rheumatoid arthritis. More research will have to be done before L-cysteine can be indicated for any of these conditions. Research to date has mostly been in animal models.
