Method of increasing the presence of glutathione in cells

摘要

A composition for increasing the presence of glutathione in cells and for treating or preventing impaired liver function. The composition includes a precursor of gluthathione, and enhancer of glutathione biosynthesis, and a third component which is a lignan or the third component is a combination of an enhancer of gluthathione regeneration and an enhancer of glutathione-mediated conjugation. The precursor of gluthathione is cysteine or is a functional equivalent of cysteine which yields cysteine when administered to a mammal undergoing treatment.
