• Cysteine is the most cost effective sulfur supplement when comparing the ratios of sulfur obtained.
  • Cysteine and methionine are the only two amino acids with sulfur. However, methionine has homocysteine as a potentially negative byproduct.
  • Cysteine is the rate limiting step in the formation of glutathione. Therefore, it is the most direct and effective source for supporting glutathione naturally.
  • Oral glutathione supplementation may interfere with your body’s natural ability to process glutathione from food sources which makes cysteine often more desirable than direct glutathione supplementation
  • Cysteine is preferred to N-acetylcysteine (NAC) because NAC is not naturally found in the body. It can indiscriminately and undesirably acetylate other compounds in the body.
