Best Liposomal Glutathione Supplements
Quick summary: Quicksilver Scientific Liposomal Glutathione is my delivery-format pick because it discloses actual reduced-glutathione milligrams in a pump serving. Its 100 mg serving is far below the liposomal pilot doses, and the two capsule alternatives here aren’t liposomal.
A phospholipid carrier doesn’t itself establish better health outcomes. I compared one liposomal liquid with two conventional capsules so you’re able to judge the format tradeoff.
Some studies found higher glutathione stores; others didn’t. Honestly, biomarker changes don’t establish longevity, disease benefit, or dependable skin lightening.
How we compared these options
I compared label transparency, study doses, brand track record, testing documentation, and cost per realistic daily amount. Check current price; value badges are editorial roles, not verified cheapest-price claims.
We did not test these products. What follows is a comparison based on labels, published research, and public third-party testing records.
The evidence references for this comparison are the single-dose oral study (PMID: 1362956); the short oral supplementation trial (PMID: 21875351); the longer oral trial (PMID: 24791752); the small liposomal pilot (PMID: 28853742); the short skin-pigmentation trial (PMID: 20524875). Ingredient trials do not verify these retail products;
The honest science bit, briefly
An early single-dose study and a four-week trial found no improvement in measured GSH. A six-month trial at 250 or 1,000 mg daily found increases in several compartments. These findings don’t establish clinical benefit. PMID: 21875351 PMID: 24791752
A 12-person liposomal pilot at 500 or 1,000 mg daily found increased stores after one month. The small sample and supplier funding limit confidence; superiority over capsules remains unproven. PMID: 28853742 A skin study found changes at two of six sites; durability and long-term safety remain unclear. PMID: 20524875
Top 3 glutathione picks
Quicksilver Scientific Liposomal Glutathione — EDITOR’S PICK
This liposomal liquid pump provides 100 mg glutathione per 1 mL (2 pumps) serving. The package contains 50 servings (50 mL).
What we like: A pump and disclosed phospholipid delivery fit the liposomal format request. Exact milligrams make its dose limitation visible.
What we don’t like: Only 100 mg per serving versus 500–1,000 mg in the liposomal pilot; premium price per gram; refrigeration after receipt and pump handling matter.
Best for: people specifically comparing liposomal liquid formats. Not for: buyers assuming the label serving matches the pilot. check price on Amazon.
If you prefer shopping HerbsPro, Quicksilver Scientific Liposomal Glutathione is usually stocked there too, sometimes at a better shelf price.
NOW Glutathione 500 mg — BEST VALUE
This vegetarian capsule provides 500 mg reduced glutathione per capsule. The package contains 60 capsules / 60 servings.
What we like: One capsule supplies 500 mg reduced GSH. It is a cost-conscious conventional-oral comparator; check current price and stock.
What we don’t like: Not liposomal; includes milk thistle and alpha-lipoic acid; indexed HerbsPro stock indicators varied, so confirm inventory at publication.
Best for: people considering a conventional 500 mg capsule. Not for: people requiring liposomes or avoiding its added ingredients. check current price on HerbsPro.
It’s also on Amazon if that’s where your Prime account lives.
Jarrow Glutathione Reduced 500 mg — CAPSULE ALTERNATIVE
This capsule provides 500 mg reduced glutathione per capsule. The package contains 60 capsules / 60 servings.
What we like: A clear 500 mg reduced-GSH amount makes price-per-gram comparison easy without implying better clinical outcomes.
What we don’t like: Not liposomal; oral bioavailability evidence is mixed; no proven disease-treatment or dependable skin-lightening outcome.
Best for: people who prefer a straightforward reduced-GSH capsule. Not for: people expecting proven skin-lightening or disease outcomes. check price on Amazon.
HerbsPro also carries Jarrow Glutathione Reduced 500 mg, and it’s the first place I check when Amazon’s price feels high.

How to choose a glutathione supplement
Reduced glutathione names the ingredient, not liposomal delivery. ‘Glutathione support’ may mean precursors. Look for actual GSH milligrams, serving volume, and carrier details. A trademark doesn’t establish finished-product efficacy, and conventional capsules are a separate format.
Compare the 100 mg liquid serving with the pilot’s 500–1,000 mg without treating it as a dose recommendation. Capsule milligrams don’t make the delivery forms interchangeable. Quicksilver contains 5 g GSH per bottle; each 60-capsule comparator contains 30 g. Those totals describe quantity, not equal benefit.
Refrigerate after receipt. Check the full phospholipid ingredient list, expiry, pump handling, and storage instructions. Confirm the carrier source and temperature on the label. Look for protective packaging and lot testing for identity, microbes, heavy metals, and freshness.
Oral GSH can cause bloating, cramps, nausea, or loose stools. Pregnancy, breastfeeding, and long-term high-dose safety data are insufficient. Discuss asthma with a clinician; inhaled-form concerns are more prominent. Cosmetic IV glutathione has different risks. Check current price per gram before paying a liquid premium.
FAQ
Is liposomal glutathione proven better than capsules?
No decisive head-to-head evidence here establishes better clinical outcomes. The small pilot measured GSH stores. Price doesn’t prove better results.
Why are two non-liposomal products on this list?
They show what conventional oral options offer for comparison. NOW and Jarrow each supply 500 mg reduced GSH, without liposomes. Only Quicksilver fits a strict liposomal-format requirement.
Does glutathione reliably lighten skin?
Not dependably. The small trial found changes at only two of six sites; durability and long-term safety remained unresolved. It doesn’t support recommending cosmetic injections.
Is NAC interchangeable with glutathione?
No. NAC is a precursor, not GSH itself. Its supplement amounts aren’t a conversion formula for glutathione. A lower-cost precursor deserves a separate discussion of evidence and risks.
Our take
Quicksilver fits the specific liposomal format request, with a substantial dose-versus-study caveat. NOW and Jarrow are clear capsule comparators, and I wouldn’t promise meaningful health changes from any of them. For context beyond this shortlist, see the NAC glutathione precursor guide and liposomal delivery explained.
