So which one should you choose?
To summarise — the reduced form stated, GSH content itself rather than yeast extract, an absorption design, a named raw material, and a price you can sustain for 12 weeks.
If you want both absorption design and a documented source —
퓨SPure Encapsulations Liposomal Glutathione (US)
It names Setria® — the raw material used in blood-GSH studies — in a liposomal 250 mg design, the only combination here covering sourcing, absorption and dose at once. It is expensive, so work out the 12-week cost first.
If sustaining 12+ weeks matters most —
재AJarrow Reduced Glutathione 500 mg (US)
It offers a high 500 mg reduced-form dose at the most accessible price. Absorption design stops at an enteric capsule and there is no named source, so it grades A — but since the skin studies all assume 12+ weeks, sustainability is itself a variable.
