What is the recommended dosage for Glutathione?

General: 250-1,000 mg/day; Skin Lightening: 500-1,000 mg/day

What are the side effects of Glutathione?

Potential side effects include: Generally well-tolerated, Mild bloating or gastrointestinal discomfort, Rare skin rash.

What is glutathione and how may it support skin health?

Glutathione is the body's master antioxidant, playing roles in detoxification and melanin regulation. It shifts melanin production toward lighter pheomelanin rather than darker eumelanin. Clinical trials, particularly from East Asia, show oral and sublingual glutathione may reduce melanin index and improve skin brightness.

What dosage of glutathione has been studied for skin lightening?

Clinical trials have used 250–500 mg of oral glutathione per day for 4–12 weeks. Both reduced (GSH) and oxidized (GSSG) forms have been studied. A Thai RCT showed significant skin lightening with 500 mg GSH daily for 12 weeks. Liposomal and sublingual forms may improve bioavailability.

What are the potential side effects of glutathione supplements?

Oral glutathione is generally well tolerated. Mild side effects include bloating and abdominal discomfort. Long-term safety at supplemental doses is not well established. IV glutathione (used off-label for skin lightening in some countries) carries additional risks and is not FDA-approved for this purpose. Zinc supplementation may support endogenous glutathione.

About

Glutathione is a tripeptide (glutamate-cysteine-glycine) serving as the body's master antioxidant. It inhibits tyrosinase and shifts melanogenesis from eumelanin (dark) to pheomelanin (light). A 2023 systematic review found oral glutathione (250-1,000 mg/day) may reduce melanin index in multiple RCTs, primarily in Asian populations.

How It Works

Tripeptide (glutamate-cysteine-glycine) serving as the body's master antioxidant; inhibits tyrosinase and shifts melanogenesis from eumelanin (dark) to pheomelanin (light); detoxifies reactive oxygen species and supports vitamin C and E recycling.
