L- Cystine helps strengthen the immune system, reduce damage from free-radicals, repair RNA-DNA in the cells and assimilation of vitamin B6. L-Cystine is closely related to the amino acid, L-Cysteine. L-Cystine aids in preventing the side effects of chemotherapy and radiation. It increases L-Glutathione levels in the lungs, liver, kidney and bone marrow. L-Cystine also has an anti-aging effect on the body which can reduce the accumulation of age spots.
S-carboxymethyl-L-cysteine, the side-chain carboxymethyl derivative of the sulfur-containing amino acid, cysteine, has been known and available for almost 80 years. During this time, it has been put to a variety of uses, but it is within the field of respiratory medicine that, presently, it has found a clinical niche. Early studies indicated that this compound underwent a rather simplistic, predictable pattern of metabolism, whereas later investigations alluded to more subtle interactions with the pathways of intermediary metabolism, as may be expected for an amino acid derivative. In addition, suggestions of polymorphic influences and circadian rhythms within metabolic profiles have emerged. These latter factors may underlie the conflicting reports regarding the therapeutic efficacy of this compound: that it appears to work well in some patients, but has no measurable effects in others. The relevant literature pertaining to the fate of this compound within living systems has been reviewed and a comprehensive précis advanced. Hopefully, this article will serve as a vade mecum for those interested in S-carboxymethyl-L-cysteine and as a catalyst for future research. ..
