Glutathione: what it is, what it costs, and who sells it
Glutathione is the body's most abundant endogenous antioxidant, sold by wellness providers as an IV or injectable form, an oral capsule or lozenge, or conflated in marketing with NAC — a different molecule the body uses to make its own glutathione. No FDA-approved glutathione drug product exists for the antioxidant or skin-lightening use most sellers market, a fact this page states up front.
This page is the start-here synthesis: what glutathione actually is, why its marketing blurs three genuinely different products together, its cost, and a live look at how the providers selling it compare. The deeper evidence question — what each of those three products' own trial data actually shows — links out from here to this site's own dedicated, independently sourced review.

What glutathione is
Glutathione is a tripeptide (glutamate-cysteine-glycine), produced inside cells rather than obtained from diet, that regulates oxidative stress and immune function. A live DailyMed search for “glutathione” (57 results) turns up zero FDA-approved therapeutic glutathione drug products — the closest hit is BSS PLUS, an FDA-approved ophthalmic surgical irrigation solution that includes glutathione as a stabilizing ingredient during eye surgery, not the antioxidant or skin-lightening product marketed here.
What's actually sold splits into three products with genuinely different evidence: IV/injectable glutathione (what most of this board's 19 rows sell, marketed for antioxidant support and skin lightening), oral glutathione (a lower-cost capsule or lozenge alternative), and N-acetylcysteine (NAC) — a precursor the body converts into glutathione, not glutathione itself, with its own separate literature.
What the evidence actually shows
The three products' trial records genuinely differ. IV/injectable glutathione's one real, well-designed randomized trial (21 Parkinson's disease patients) was well tolerated with no significant difference on the primary outcome — a null-leaning result, not a positive one. Its flagship consumer claim, skin lightening, rests on a single study a dedicated 2018 review calls, in its own words, “a dubious study design and apparently flawed analysis.” Oral glutathione has a real, positive 6-month RCT behind it — slower and more modest than an injection promises, but a genuine finding. Read the full breakdown, product by product, in our glutathione evidence review.
Regulatory status, briefly
Glutathione is a long-recognized endogenous tripeptide, not a novel synthetic peptide under FDA Pharmacy Compounding Advisory Committee (PCAC) review — like NAD+, its absence from FDA's 2026 PCAC meeting agendas reflects a different regulatory category, not an earlier, unresolved stage of the same process this site's peptide reviews (BPC-157, TB-500, GHK-Cu) document. See our evidence review for the full regulatory picture.
Safety, the condensed version
The one real, well-designed randomized trial of IV glutathione (in Parkinson's disease patients, 1,400 mg three times weekly for 4 weeks) found it well tolerated, with no serious adverse-event signal reported. That is a genuine positive on safety — it does not extend to an efficacy claim, since the same trial found no significant difference on its primary outcome measure. For the full safety and tolerability discussion across all three product forms, see our glutathione evidence review. None of this is a recommendation for or against glutathione — talk to a licensed clinician about your own situation.
Compare providers
Every provider below sells glutathione and is ranked the same way our full board ranks it: pharmacy-sourcing disclosure first, advertised price second — never a paid placement. The preview shows the top 4 rows; the full board carries all 19, plus a detailed write-up for each, including product form and the 8 providers this board shares with the NAD+ board.
/ The board
Any paid placement on this board is marked Partner and listed first, as a disclosed commercial position — within that group, and separately within every other row, every provider is still ranked on the criteria printed on this page, never anything else (see disclosure). Full write-ups below.
“Flat price” means one all-in monthly figure with no separate membership or lab fee; any other pricing chip names the mechanic that gets in the way, or that the provider has not stated one. “Labs” is whether bloodwork is required, optional, not used, or not stated on the provider's own site. The pharmacy chip states a facility type (503A pharmacy, 503B facility) only where the provider publishes one we could cite; “Not disclosed” means we read their site and they do not say, and “Unverified” means nobody has checked this company's pharmacy sourcing yet — of the 19 providers on this board, 7 publish a facility type at all. Every provider here includes the clinician consult. Each row above shows the exact date its price was checked on that provider's own site — prices can change without notice.
