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.

Read the complete Glutathione guide →Plain reduced glutathione — the form with the most-debated oral absorption (Witschi 1992, Allen 2011 negative; Richie 2015 positive over 6 months) — and, unlike Healthy Origins, NOT a named branded source. Sits a notch below the named-Setria capsule on the form axis and well below the liposomals/S-acetyl that exist to solve absorption.
A full 500 mg per capsule, squarely inside the 250-1000 mg/day range Richie 2015 used to raise body stores. No under-dosing — on dose alone it matches the best plain-form picks. This is where the budget capsule earns most of its score.
Jarrow is a long-trusted brand and the product is non-GMO, vegan, gluten-free and single-ingredient — but it carries NO named branded glutathione source (the brand page doesn't claim Setria) and no NSF/USP seal, so there's less to independently verify than with the Setria picks. Honest, clean, but lower on verifiable provenance.
At ~$0.23 per 500 mg capsule it's the lowest STICKER price on the list and excellent per-day value, undercut on cost-per-serving only by the 240-count bulk Nutricost. The cheapest low-commitment way to run a real plain-form dose.
One vegan capsule a day, single-ingredient, no timing demands — easy to take consistently over the months repletion requires, and vegan/soy-free where the softgel liposomals aren't. The only drag is carrying the plain-form absorption caveat into daily use.
“500 mg of reduced (non-oxidized) L-glutathione per capsule.”
The full 500 mg reduced-GSH dose is as stated and sits squarely in the 250-1000 mg/day range Richie 2015 used. Reduced (non-oxidized) is indeed the active form of glutathione — accurate on both dose and form.
“Vegan, non-GMO, and gluten-free.”
Jarrow states non-GMO, vegan, and gluten-free in a vegetarian capsule — a genuine, verifiable advantage over the gelatin/soy softgel liposomals for buyers with those requirements.
“Oral glutathione raises your glutathione levels.”
Not reliably or quickly. Witschi 1992 saw no plasma rise after a single dose; Allen 2011 saw no biomarker change over 4 weeks; only Richie 2015 showed body stores rising, over six months. 'Raises your levels' is unverified as a fast or guaranteed effect — slow repletion appears possible but isn't a sure thing.
“Supports antioxidant defenses, immune health, and detoxification.”
Glutathione's antioxidant, immune, and phase-II detox roles are established biology, so the support rationale is sound IF the oral dose reaches your cells — which for plain reduced GSH is the debated step. Honest as biology, conditional as a supplement claim.
“Premium-quality glutathione from a trusted brand.”
Jarrow is a long-established, trusted brand and the product is clean and single-ingredient — fair grounds for 'quality.' But 'premium' is qualified by the absence of a named branded source (no Setria claim) and any third-party seal, so it's solid mainstream quality rather than a verifiably premium-source product.
The strongest case for Jarrow is experimental economics. Plain oral glutathione's absorption is debated, so before anyone spends $40-55 on a named-source or liposomal product, it's reasonable to test whether plain-form GSH does anything noticeable for them — and at ~$14 for a full 500 mg, this is the cheapest credible way to run that test. If you respond, you can decide whether to upgrade to a named source or a liposomal; if you don't, you've spent very little finding out.
Jarrow's own product page doesn't state Setria, so neither do we. That single fact is the difference between this and the #1 pick: Healthy Origins carries the named, verifiable Setria material; Jarrow carries clean generic reduced glutathione. You save real money here, and you give up branded provenance. Neither is dishonest — it's a transparent price-versus-source decision, and we'd rather flag it plainly than imply a named source that the brand itself doesn't claim.
Being the budget pick doesn't exempt it from the form debate: this is plain reduced glutathione, the version Witschi 1992 and Allen 2011 found little-to-nothing from short-term, and that Richie 2015 found raised body stores only over six months. So set expectations accordingly — a slow, cumulative repletion play, judged at the multi-month mark. If that uncertainty is unacceptable to you, the liposomal (#2, #3) and S-acetyl (#4) forms are the hedge, at higher cost.
A quiet advantage worth naming: Jarrow is vegan, non-GMO, gluten-free, and single-ingredient, with no soy lecithin or gelatin — unlike the softgel liposomals, which are neither vegan nor soy-free. So for a buyer with those dietary requirements, the plain reduced capsules (this and Healthy Origins #1) are effectively the only tier available, and Jarrow is the cheapest way into it. You accept the plain-form absorption caveat as the price of the cleaner, animal-free formulation.
Jarrow Formulas Glutathione Reduced is the pick for the cost-conscious buyer who wants to run a real plain-form glutathione protocol — or simply test whether it does anything for them — without spending much. A full 500 mg of clean, vegan, single-ingredient reduced GSH from a trusted brand at the lowest sticker price on the list is a genuinely sensible, honest budget choice. We rank it at #5 for two transparent reasons, not because it's poorly made. It carries no named branded source — Jarrow's own page doesn't claim Setria, so neither do we — which means less verifiable provenance than the #1 Setria capsule. And it's the plain reduced form, the one with the most-debated oral absorption: judge it over months (Richie 2015), not days (Allen 2011 found nothing in four weeks). If a named source matters, pay up to Healthy Origins (#1); if the absorption debate worries you, the liposomals (#2, #3) are the hedge; if you mainly want to raise glutathione status as cheaply as possible, weigh NAC. But for the lowest-commitment way to try direct glutathione, buy this, take one capsule daily, and reassess at the multi-month mark.
