Glutathione for Alzheimer's Disease

Start: February 1, 2021
End: May 31, 2025
Enrollment: 52

What Is This Study About?

Research suggests that low levels of glutathione, a protective substance made in the body, may be linked to Alzheimer's disease. Glutathione levels can be increased by taking supplements of glycine and cysteine, which combine in the body to make glutathione. This clinical trial will evaluate the effects of glycine-cysteine supplements in people with Alzheimer's disease. Participants will be randomly assigned to receive supplements of either glycine-cysteine or a placebo for 24 weeks. Participants will undergo MRI and PET brain imaging scans, assessments, and tests so researchers can measure changes in cognition, glutathione levels, brain cell energy use, and brain inflammation.
