Our verdict

Swanson Amino Acid L-Glutathione 100 mg for Antioxidants works out to $0.18 per serving of glutathione, at 100mg per serving in capsule form. That puts it the cheapest quarter of the 43 glutathione products we can price per dose, where the typical serving costs $0.33, a Value Index of 1.8 where the median product is 1.0. One container lasts 100 days at the label dose of 1 serving a day, about $5.46 a month. We could not verify a third-party certification for Swanson Premium Brand in a public registry.
