Glutathione 1 g, 2 g, 3 g or 4 g in 100 mL normal saline.

What the research shows

Glutathione occupies a unique position in human biochemistry. It is the most abundant intracellular antioxidant in the body and its central redox regulator — the molecule that sets the oxidative tone of the cell 1. It is also the specific molecule liver enzymes conjugate onto toxins during Phase II detoxification so those compounds become water-soluble and can be excreted 2. Glutathione levels fall sharply with age, and a controlled clinical study using stable-isotope tracing found that restoring glutathione synthesis returned older adults' oxidative stress markers to youthful levels within two weeks 3.

The intravenous clinical evidence is broader than most people expect. In an open-label clinical trial in early Parkinson's disease, intravenous glutathione at 600 mg twice daily produced a 42% improvement in disability, with benefit lasting for months after treatment ended 4; a later randomized, double-blind, placebo-controlled trial confirmed intravenous glutathione was well tolerated at 1,400 mg three times weekly, with no participant discontinuing treatment 5. In peripheral arterial disease, a randomized double-blind placebo-controlled trial found five days of intravenous glutathione increased pain-free walking distance by roughly 37% and measurably improved both large- and small-vessel blood flow 6. A controlled human interventional study found infused glutathione improved the way coronary arteries relax and dilate, with the largest benefit in people who had cardiovascular risk factors 7.

Glutathione has also been studied as a protective agent alongside other treatments and in reproductive and dermatologic contexts. A randomized, double-blind, placebo-controlled trial found intravenous glutathione given before chemotherapy protected patients' nerves, cutting significant neuropathy from 11 cases to 2 8, and a randomized double-blind trial found adding glutathione to cisplatin therapy improved women's quality of life across mood, nausea, nerve symptoms and daily functioning 9. In a randomized double-blind placebo-controlled crossover trial, injected glutathione at 600 mg significantly improved sperm motility and morphology 10. On the dermatologic side, a randomized, double-blind, placebo-controlled trial in healthy women found glutathione lowered melanin index and UV spots, significantly reduced wrinkles and increased skin elasticity 11; a mechanistic review describes several defined pathways for this, including switching pigment production from darker eumelanin toward lighter pheomelanin 12.

    Glutathione is the body's most abundant intracellular antioxidant and its central redox regulator.

    This widely cited review in Molecular Aspects of Medicine describes glutathione as the most abundant low-molecular-weight thiol compound synthesized in human cells. The authors detail its role in protecting cells from oxidative damage and from the toxicity of reactive xenobiotic electrophiles, and in maintaining the cell's overall redox balance. The paper covers where oxidants and electrophiles come from, how glutathione eliminates them (by reduction and by conjugation), and how glutathione synthesis is regulated - including therapeutic strategies for raising cellular glutathione content.

    Glutathione is the molecule liver enzymes attach to toxins during Phase II detoxification so they can be excreted.

    This Annual Review of Pharmacology and Toxicology review covers the three mammalian glutathione transferase (GST) families - cytosolic, mitochondrial, and microsomal. These Phase II enzymes conjugate glutathione onto electrophilic xenobiotics such as carcinogens and environmental pollutants, and also onto endogenous compounds including aldehydes, quinones, and lipid hydroperoxides generated during oxidative stress. The review also describes glutathione transferases' roles in leukotriene, prostaglandin, and steroid hormone biosynthesis, and in modulating gene expression through nuclear receptor pathways. Glutathione is the required cofactor for this entire conjugation system.

    Glutathione levels fall sharply with age, and restoring glutathione synthesis returns older adults' oxidative stress markers to youthful levels within two weeks.

    Using stable-isotope infusion techniques, researchers compared eight older and eight younger adults. Older subjects had markedly lower red blood cell glutathione concentrations, a substantially reduced rate of glutathione synthesis, and elevated markers of oxidative stress and oxidant damage. After just two weeks of supplementation with the glutathione precursors cysteine and glycine, older subjects' glutathione synthesis rates and concentrations were fully restored and their oxidative stress markers fell to levels comparable with the young control group. Route: dietary/oral precursor supplementation; glutathione status measured directly in blood.

    Intravenous glutathione at 600 mg twice daily produced a 42% improvement in disability in early Parkinson's disease, with benefit lasting months after treatment stopped.

    Nine patients with early, previously untreated Parkinson's disease received 600 mg of reduced glutathione intravenously twice daily for 30 days. All patients improved significantly, with an average 42% decline in disability scores. The therapeutic benefit persisted for two to four months after glutathione was discontinued. The authors concluded that in untreated Parkinson's patients, glutathione has symptomatic efficacy and possibly retards disease progression - work motivated by the established finding that glutathione is depleted in the substantia nigra of Parkinson's patients in proportion to disease severity. Route: intravenous, 600 mg per dose.

    In a randomized double-blind trial, intravenous glutathione was well tolerated at 1,400 mg three times a week, with no participant stopping treatment because of side effects.

    Twenty-one Parkinson's disease patients were randomized to receive 1,400 mg of intravenous glutathione or placebo three times weekly for four weeks. Glutathione was well tolerated, there were no withdrawals because of adverse events in either group, and reported adverse events were similar between glutathione and placebo. During the treatment period, motor scores on the Unified Parkinson's Disease Rating Scale improved by an average of 2.8 units more in the glutathione group than in placebo. The investigators concluded the data suggest the possibility of a mild symptomatic effect warranting a larger study. Route: intravenous.

    Five days of intravenous glutathione increased pain-free walking distance by roughly 37% and measurably improved both large- and small-vessel blood flow in patients with peripheral artery disease.

    Forty patients with Fontaine stage II peripheral obstructive arterial disease at Verona University were randomized to intravenous glutathione twice daily or saline twice daily for five days. Pain-free walking distance rose to 196 +/- 15 meters with glutathione versus 143 +/- 11 meters with placebo (P<.04). Macrocirculatory flow after treadmill testing improved to 9.3 +/- 2 versus 2.8 +/- 0.5 mL per 100 mL/min (P<.002), and post-ischemic hyperemia measured by laser Doppler rose to 14.4 +/- 3.2 versus 6.18 +/- 1.5 perfusion units (P<.005). The authors concluded glutathione prolongs pain-free walking distance and improves both macrocirculatory and microcirculatory function. Route: intravenous infusion.

    Infused glutathione improved the way human coronary arteries relax and dilate, with the largest benefit in people who had cardiovascular risk factors.

    In 26 subjects without significant coronary narrowing, researchers measured artery diameter and blood flow responses to acetylcholine before and during direct infusion of reduced glutathione at 50 mg/min, using coronary angiography and a flow wire. Glutathione suppressed the abnormal constrictor response to acetylcholine, enhanced the blood flow increase, and potentiated the vasodilator effect of nitroglycerin. The effects were most pronounced in subjects with coronary risk factors. The authors concluded that glutathione improves endothelial vasomotor function in the human coronary circulation. Route: direct intra-arterial (intracoronary) infusion.

    Intravenous glutathione given before chemotherapy protected patients' nerves, cutting significant neuropathy from 11 cases to 2.

    Fifty-two patients with advanced colorectal cancer on a bimonthly oxaliplatin regimen were randomized to receive 1,500 mg/m2 of glutathione as a 15-minute intravenous infusion before oxaliplatin, or saline placebo. Neurologic and electrophysiologic assessments were done at baseline and after 4, 8, and 12 cycles. After eight cycles, grade 2-4 neurotoxicity occurred in only 2 glutathione patients versus 11 placebo patients (P=.003); after 12 cycles, 3 versus 8 (P=.004). The authors concluded glutathione is a promising agent for preventing oxaliplatin-induced neuropathy and does not reduce the anticancer activity of the chemotherapy. Route: intravenous.

    Adding glutathione to cisplatin therapy improved women's quality of life across mood, nausea, nerve symptoms and daily functioning, and let far more patients complete full-dose treatment.

    One hundred fifty-one women with stage I-IV ovarian cancer were randomized in a double-blind trial to cisplatin with or without glutathione. Significantly more glutathione-treated patients completed all six full-dose cycles (58% versus 39%, P=.04), and kidney function was better preserved (74% versus 62% retained, P=.006). On quality-of-life assessment, glutathione-treated women reported substantial improvements in depression, nausea and vomiting, peripheral neuropathy, hair loss, and breathlessness, along with an enhanced ability to carry out normal daily activities. Route: intravenous, given alongside chemotherapy.

    Injected glutathione at 600 mg significantly improved sperm motility and morphology in a placebo-controlled crossover trial.

    Twenty infertile men with dyspermia associated with varicocele or genital tract inflammation received either 600 mg of glutathione or matched placebo by injection every other day for two months, then crossed over to the alternative treatment for two further months. Standard semen analysis and computer-assisted motility analysis showed a statistically significant positive effect of glutathione therapy on sperm motility - particularly the percentage of forward progressive motility - and on sperm morphology. The authors concluded glutathione could serve as a therapeutic approach in these andrological conditions. Route: parenteral (intramuscular injection), 600 mg per dose.

    In a randomized trial in healthy women, glutathione supplementation lowered melanin index and UV spots, significantly reduced wrinkles, and increased skin elasticity.

    Healthy female subjects were randomized in a double-blind, placebo-controlled, three-arm design to reduced glutathione (GSH, 250 mg/day), oxidized glutathione (GSSG, 250 mg/day), or placebo for 12 weeks. Melanin index and ultraviolet spots at all measured sites - face and arm - trended lower with both GSH and GSSG than with placebo. Subjects receiving GSH showed a significant reduction in wrinkles at several evaluated sites, and both glutathione forms showed a trend toward increased skin elasticity. There were no serious adverse effects throughout the study. Route: oral.

    Glutathione brightens skin through several defined mechanisms, including switching pigment production from dark eumelanin toward lighter pheomelanin.

    This dermatology review synthesizes the in vitro and in vivo evidence on how glutathione lightens skin. The described mechanisms are: direct inactivation of the enzyme tyrosinase by binding to its copper-containing active site; mediating the switch from eumelanin (dark pigment) to phaeomelanin (lighter pigment) production; quenching the free radicals and peroxides that would otherwise activate tyrosinase and drive melanin formation; and modulating the depigmenting activity of melanocyte-targeting agents. The authors position these findings as the foundation for glutathione's therapeutic potential in pigmentation disorders.
