Product Description:

This capsule combines glutathione with collagen peptides, vitamins A, C and E, and selenium, and is marketed for skin health. Glutathione is the body's main intracellular antioxidant, made from cysteine, glutamate and glycine. Vitamins C and E are antioxidants that work together, vitamin A supports skin cell turnover, selenium is a cofactor for glutathione peroxidase, and collagen peptides provide amino acids for connective tissue.

Oral glutathione is largely broken down in the gut, and whether it raises tissue levels meaningfully is debated; small studies show inconsistent results. Its popularity rests largely on claims of skin lightening, which are not well supported by evidence. Regulators in several countries have warned against unapproved glutathione products marketed for whitening, particularly injectable forms. Vitamin A should not exceed safe limits, especially in pregnancy, and selenium has a narrow margin between adequate and toxic intake.

Sourcing notes. Buyers should specify the dose of each ingredient, with vitamin A and selenium checked against the destination's supplement limits. Skin-lightening claims are prohibited or restricted in many markets. Glutathione's regulatory status as a food ingredient varies by market, and the collagen source matters for halal, kosher and vegetarian buyers.
