What Is Glutathione?
Glutathione is a tripeptide made inside the body from cysteine, glutamate, and glycine.
A cellular antioxidant
Glutathione can donate reducing power to help neutralize reactive oxygen species. Enzymes then help recycle oxidized glutathione back into its active form.
- Supports antioxidant defenses
- Participates in normal detoxification reactions
- Helps maintain proteins in their functional state
Why levels vary
Glutathione status can be influenced by age, nutrition, illness, environmental exposures, physical stress, and the body’s demand for repair. A laboratory result should always be interpreted in context by a health professional.
What glutathione is not
Glutathione is not a cure-all. Claims that it prevents or treats specific diseases require strong clinical evidence and should not replace medical care.
