Deficient synthesis of glutathione underlies oxidative stress in aging and can be corrected by dietary cysteine and glycine supplementation.
After treatment with cysteine and glycine for 14 d, compared with presupplementation values, the elderly subjects in the postsupplemented state had a 94.6% higher RBC glutathione concentration

Deficient synthesis of glutathione underlies oxidative stress in aging and can be corrected by dietary cysteine and glycine supplementation - PMC
Background: Aging is associated with oxidative stress, but underlying mechanisms remain poorly understood.Objective: We tested whether glutathione deficiency occurs because of diminished synthesis and contributes to oxidative stress in aging and whether ...
