A pleasant practitioner-brand liquid liposomal — for buyers who specifically want the liquid format.
Designs for Health Liposomal Glutathione rounds out the list as the practitioner-brand liquid liposomal for people who simply prefer a flavored dropper to a softgel or capsule. The liposomal delivery is the same bioavailability strategy as the other liposomals here, the lemon-peppermint format is pleasant, and 50 servings per bottle is a decent runway — a sensible alternative to Quicksilver if you want a liquid liposomal at a friendlier price.
It lands at #9 for two honest reasons. Its listing doesn't name a branded glutathione source the way the Setria and OPITAC picks do, so you can verify less about the raw material; and at 100 mg per serving with a liquid-liposomal price premium, it's neither the cheapest nor the best-documented option. That makes it a format-driven 'consider' rather than a broad recommendation. Here's the full breakdown.

Read the complete Glutathione guide →Liquid liposomal delivery — glutathione bonded to phospholipids, the same bioavailability strategy with category-level human support (Sinha 2018) that addresses plain GSH's debated absorption (Witschi 1992). Scores well on form, but a notch below the named-source liposomals because its listing doesn't specify a branded glutathione raw material.
100 mg per serving — a low elemental dose, scored in the context of liposomal delivery (smaller protected dose) but with no established liposomal dose-response to validate it, and well under the 500 mg plain capsules. The dropper allows more, at the cost of bottle longevity. Honest mid-low score on the dose axis.
Reputable practitioner-channel brand, non-GMO, gluten- and dairy-free, naturally flavored — but the listing does NOT name a branded glutathione source (no Setria/OPITAC), so there's less verifiable provenance than the named-source picks, and no third-party NSF/USP seal. Solid brand reputation; weaker raw-material traceability.
At ~$0.80 per 100 mg serving it carries a liquid-liposomal price premium over capsules, but it's meaningfully cheaper per serving than Quicksilver (#7) and the 50-serving bottle gives a reasonable runway. Fair value within the liquid-liposomal niche; not competing with plain-capsule economics.
Pleasant lemon-peppermint flavor and flexible dropper/pump dosing are genuine pluses for people who prefer liquids, and 50 servings is a decent supply. Loses ground to capsules on the hold-then-swallow routine and the shorter shelf life of an opened liquid. A good fit specifically for liquid-preferring buyers.
“Liquid liposomal delivery bonded to phospholipids for enhanced absorption.”
Supported at the form level — liposomal delivery has human category evidence (Sinha 2018, PMID 28853742) and addresses plain GSH's debated absorption (Witschi 1992). 'Partial' because that evidence isn't for this specific product, and liposomal quality varies by manufacturer; the mechanism is sound, product-specific proof isn't claimed.
“100 mg of glutathione per 1 mL serving.”
The 100 mg per 1 mL (dropper) serving is as stated. A low elemental dose, scored in the context of the liposomal format and the dropper's dosing flexibility.
“Made with a premium branded glutathione source.”
The listing does not specify a named branded glutathione source (no Setria or OPITAC stated), so any 'premium branded source' implication can't be verified. It's glutathione in a liposomal matrix from a reputable brand — but the specific raw material isn't documented, unlike the named-source picks.
“Practitioner-grade quality.”
Designs for Health is a genuine practitioner-channel brand with a non-GMO, gluten- and dairy-free, naturally-flavored formulation — fair grounds for 'practitioner-grade' on brand and formulation. 'Partial' because the unnamed glutathione source and absence of a third-party seal limit how far the quality claim can be independently substantiated.
“Non-GMO, gluten- and dairy-free, naturally flavored.”
The product is non-GMO, gluten- and dairy-free, and naturally flavored (lemon peppermint) as stated — verifiable formulation attributes and a real plus for the liquid format's palatability.
If you specifically want a liquid liposomal, this is the friendlier-priced option next to Quicksilver (#7). Same broad strategy — glutathione bonded to phospholipids in a liquid you hold in the mouth — with a pleasant lemon-peppermint flavor, dropper dosing flexibility, and 50 servings per bottle, at meaningfully less per serving than Quicksilver. For the liquid-preferring buyer who doesn't need the most aggressive sublingual nanoliposomal pitch, it covers the format well.
What separates this from the higher-ranked liposomals is provenance: its listing doesn't name a branded glutathione source, where Pure Encapsulations and Core Med Science specify Setria and Quicksilver specifies OPITAC. There's nothing to suggest the glutathione is poor — but you can't point to a specific clinically-referenced raw material, and for an honest evaluation that matters. If verifiable source is part of your decision, the named-source picks earn their edge here; if you trust the practitioner brand, it's a smaller concern.
As with the other liquid liposomal, the 100 mg serving is low next to the 500 mg plain capsules, and the liposomal-dose-response that would justify a smaller number isn't established. The dropper lets you take more, but that empties the 50-serving bottle faster and raises the effective cost. Treat 100 mg as a reasonable-by-convention liposomal serving rather than a validated target, and factor the low elemental dose into the value math against a 500 mg capsule.
The fair summary: this is a format-driven pick. Choose it because you genuinely prefer a flavored liquid dropper and want a practitioner-brand liposomal at a reasonable price — that's a legitimate reason, and it does that job well. Don't choose it as a general 'best glutathione,' because the unnamed source, low dose, and price premium make a named-source capsule (#1), a higher-dose liposomal (#3), or even NAC more rational for value- or provenance-led buyers. It's a good answer to a specific preference, not a broad recommendation.
Designs for Health Liposomal Glutathione is the pick for one specific preference: you want a flavored liquid liposomal and would rather not swallow softgels or capsules. For that buyer it's a sensible, friendlier-priced alternative to Quicksilver — same liposomal strategy, pleasant lemon-peppermint flavor, dropper dosing flexibility, and a 50-serving bottle from a reputable practitioner-channel brand. It sits at #9 as a 'consider' for two transparent reasons. Its listing doesn't name a branded glutathione source the way the Setria and OPITAC picks do, so you can verify less about the raw material; and at 100 mg per serving with a liquid-liposomal price premium, it's neither the cheapest nor the best-documented option. So buy it specifically for the liquid format and flavor; if a verifiable named source matters, choose Healthy Origins (#1, Setria) or Quicksilver (#7, OPITAC); if you want more dose-per-dollar in liposomal form, Core Med Science (#3); and if value or the cheapest route to glutathione status is the goal, a plain capsule (#8) or NAC. A good answer to a specific preference — not a broad recommendation.
The named-source liquid alternative — OPITAC (Kyowa) in a sublingual nanoliposomal pitched at the most aggressive absorption. Pay more for named provenance and delivery ambition.
See it on the list →A full 500 mg of named Setria per serving in liposomal form — five times the elemental dose, with verifiable provenance and the best liposomal value, if you'll take a softgel instead of a liquid.
See it on the list →The value-and-provenance alternative — named Setria at a full 500 mg per capsule, lowest cost-per-day among named-source picks. Buy this if format isn't the deciding factor.
See it on the list →Oral liposomal glutathione raised body stores and immune markers in humans — the category evidence behind this product's liposomal delivery (not a trial of this specific product).
A single 3 g oral dose of plain glutathione produced no plasma rise — 'negligible' availability. The plain-form objection that liposomal delivery, including this liquid format, is built to address.
250-1000 mg/day plain oral glutathione raised body stores over 6 months — context for how much more elemental glutathione a 500 mg capsule supplies than this 100 mg liquid serving.
