KEY TAKEAWAYS
- Made naturally by the body from three amino acids
- Central to antioxidant defense and liver detoxification pathways
- Human research on supplementation is limited but growing
02 / MECHANISM
How it works
Glutathione neutralizes reactive molecules that can damage cells, helps recycle other antioxidants such as vitamins C and E, and supports the liver's detoxification processes. Levels can fall with age, illness, and stress.
03 / EVIDENCE
What the research shows
Small clinical studies show supplementation can raise glutathione levels in the body and may affect markers of immune function and oxidative stress. Evidence for broader benefits — including skin brightening, which is often marketed — is limited and inconsistent.
