Jarrow Formulas Glutathione Reduced is the honest budget pick: a full 500 mg of clean reduced glutathione, vegan and single-ingredient, from a brand people already trust, at the lowest sticker price on the list. For the buyer who wants to run a real plain-form glutathione experiment without spending much, it's the rational starting point.
Two things we will not dress up. First, source: Jarrow's own product page does not claim Setria, so we don't either — you're buying clean generic reduced GSH, not the named branded material Healthy Origins (#1) carries. Second, form: this is plain reduced glutathione, the version with the most-debated oral absorption (Witschi 1992 and Allen 2011 negative short-term; Richie 2015 positive only over six months). Both are real trade-offs, and both are exactly why this is a budget pick rather than the overall winner. Here's the full breakdown.
