DIETARY GLYCINE REGULATION OF GLUTATHIONE SYNTHESIS Availability of the amino acid cysteine is known to be rate-limiting for the synthesis of glutathione, and it is well documented, both clinically and in animal studies, that cysteine supplementationmost practically achieved by administration of N-acetylcysteine (NAC)can boost glutathione synthesis and levels.5,6 Dietary glycine levels may likewise modulate glutathione synthesis
