Glutathione

Antioxidant tripeptide

Supplement / compounded

What it is

A naturally occurring antioxidant tripeptide, sold as an oral supplement and marketed in injectable “wellness” and skin-whitening contexts.

What the evidence shows

Limited robust human evidence for the skin-whitening and “detox” claims commonly marketed.

Safety & reported risks

Oral supplement use is generally low-risk; unapproved injectable/IV use carries the usual product-quality and oversight concerns.

Status in Australia

Oral supplements are regulated differently from medicines. Injectable or IV “wellness” and skin-whitening uses are not approved indications.

How it’s lawfully accessed

Oral supplements are lawfully sold; injectable “wellness” use is not an approved pathway.
