What it is: Glutathione is a small peptide, specifically a tripeptide, made up of the amino acids glutamate, cysteine, and glycine. It functions as one of the body’s most important intracellular antioxidants.
What it does: Glutathione helps protect cells from oxidative damage by neutralizing free radicals and is involved in detoxifying harmful substances, especially in the liver. It also helps regenerate other antioxidants like vitamins C and E.
How it is used: It is frequently used in supplements aimed at antioxidant support, detoxification, healthy aging, immune system maintenance, and overall cellular protection.
Natural sources and supplement forms: Glutathione is produced by the body, particularly in the liver, and is present in foods such as avocados, spinach, and asparagus. Supplement forms include reduced (L-glutathione), liposomal, and S-acetyl glutathione, which may have different absorption profiles.
Why it appears in supplement formulas: Brands use glutathione for its role in promoting antioxidant defenses, supporting detoxification, and maintaining healthy immune and cellular function.
What to know before use: Oral glutathione may have inconsistent absorption in the body; discuss with a healthcare professional before use if you have liver issues, are pregnant, or are taking medication for chronic conditions.

Interesting Fact
Glutathione: Your Body’s Intracellular Antioxidant
Glutathione is naturally produced in every cell of the body, especially in the liver, and acts as a primary line of defense against oxidative stress. Unlike many antioxidants that work outside cells, glutathione works inside the cells, helping to neutralize free radicals and recycle other antioxidants, such as vitamins C and E, making it a cornerstone of cellular health support.
