Glutathione
Also known as: GSH, L-Glutathione, Reduced Glutathione
Glutathione is the body's master antioxidant — a tripeptide of glutamate, cysteine, and glycine produced naturally in every cell. It is essential for detoxification, immune function, and combating oxidative stress. Injectable glutathione bypasses poor oral absorption to directly raise systemic levels, supporting liver detox, skin brightening, immune defense, and anti-aging.

Half-Life
Short in plasma (~10 min), but cellular effects last much longer
Common Dose
200–600 mg per injection
Route
Subcutaneous
Frequency
1–3 times per week
Mechanism of Action
Glutathione directly neutralizes free radicals and reactive oxygen species. It is a critical cofactor for liver phase II detoxification (conjugation reactions), regenerates other antioxidants like vitamin C and E, supports mitochondrial function, and modulates immune cell activity. It also inhibits tyrosinase (the enzyme that produces melanin), which underlies its skin-lightening effect.
