Low GSH in aging is associated with lower intake of GSH precursors, mainly cysteine, and lower GSH synthesis evidencing diminished function of nuclear factor erythroid 2related factor 2 (Nrf2)-dependent inductive mechanisms that enhance glutamate cysteine ligase expression, rate limiting factor for the synthesis of GSH (McCarty and DiNicolantonio, 2015)
