Adequate amino acid availability is required to sustain protein synthesis, antioxidant synthesis, and metabolic homeostasis, and reductions in amino acid supply may therefore influence the capacity of redox-buffering systems that maintain oxidative stability because glutathione synthesis depends on cysteine and related amino acid precursors [78, 79]
