Glutathione is the most abundant and important antioxidant produced by the human body. It plays a central role in detoxification (neutralizing free radicals, heavy metals, and environmental toxins), immune system regulation, DNA repair, and cellular energy production. Depleted glutathione levels are associated with accelerated aging, chronic fatigue, neurodegenerative diseases, liver disease, and increased susceptibility to infections. This test measures total glutathione in the blood. It is frequently ordered by longevity-focused clinicians, patients with chronic illness, and those monitoring their antioxidant status during detoxification protocols or supplementation with NAC (N-acetylcysteine) or liposomal glutathione.
