Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Elderly humans have an increased risk of dementia which begins as mild defects in memory called mild cognitive impairment. Glutathione (GSH), a key endogenous antioxidant has been linked to cognition. This exploratory study will investigate mechanisms linked to GSH for cognitive impairment (and improvement) by studying humans with mild cognitive impairment who will be evaluated 12-weeks after receiving either N-acetylcysteine and glycine (GSH precursors), or receiving alanine, and a further 12-weeks after stopping these supplements.
