Daily oral glutathione for 6 months raised glutathione levels in blood and cells of healthy adults.
Double-blind, placebo-controlled RCT in 54 non-smoking adults taking 250 or 1,000 mg a day for 6 months; the high dose raised erythrocyte, plasma and lymphocyte glutathione by 30-35%. Non-liposomal form.
Liposomal glutathione raised blood glutathione within 1-2 weeks and lowered an oxidative stress marker in healthy adults.
Pilot study in 12 healthy adults taking 500 or 1,000 mg liposomal glutathione a day for 4 weeks; whole-blood glutathione rose up to 40% and plasma 8-isoprostane fell 35%. No placebo group; industry-funded.
A single dose of one liposomal glutathione product gave higher blood levels than plain glutathione in a small study.
Open-label study in 12 healthy adults (6 per group) given a single 1 g dose; peak plasma glutathione was about six times higher with the liposomal form than plain glutathione. Run by the product's maker.
