Glutathione, brain metabolism and inflammation in Alzheimer's disease
NCT ID NCT04740580
First seen Sep 09, 2026 ยท Last updated Sep 09, 2026
Summary
Alzheimer's disease (AD) is associated with significant, progressive cognitive decline. Key defects in mitochondrial fuel metabolism insulin resistance, inflammation and decreased brain glucose uptake are linked to AD. This trial will investigate the effects of supplementing glycine and N-acetylcysteine vs. alanine as placebo on these defects in AD, and examine the effects on cognition.
