Glutathione

The regulatory record is more specific than the clinical one, and it names a real episode. FDA warned compounders on 1 February 2019 not to use a named glutathione L-reduced powder for sterile injectables after reports concerning seven people who received a drug compounded with L-glutathione and experienced adverse events attributed to potentially high endotoxin levels. FDA has separately and repeatedly told compounders not to use dietary-supplement grade glutathione for injectables, because material labelled for supplement use may carry impurities and contaminants including endotoxins. A narrative review of the skin-lightening literature records anaphylaxis and hepatotoxicity associated with the intravenous route, alongside the absence of any standardised dosing protocol.

What is not established

An approved injectable, a standardised dose, and any established basis for the use it is most sold for. FDA has approved no injectable product for skin whitening or lightening. The reported harms by that route include serious allergic reactions and liver injury, and the reviews note there is no dosing standard to depart from in the first place.

What distinguishes Glutathione

Seven people, one named powder, one dated warning. This is the compound where the failure mode a documented supply chain is built against has actually been published, with a date and a count, by a regulator: supplement-grade material used to make an injectable, and endotoxin harming the people who received it. Every claim this business makes about batch certificates, endotoxin panels and grade is abstract until a buyer reads this page.
