Glutathione (GSH) is a tripeptide of glutamic acid, cysteine and glycine present in nearly every cell, often called the “master antioxidant” for its central role in neutralising free radicals, recycling vitamins C and E, and supporting liver detoxification. Cellular reserves naturally decline with age, pollutant exposure and stress. Only the reduced (GSH) form is biologically active, unlike the oxidised form (GSSG), which needs energy-costly enzymatic conversion to become functional again.

Standard oral glutathione, as powder or tablets, is largely degraded by stomach acid and digestive enzymes before reaching the bloodstream. Liposomal technology solves this by encapsulating each glutathione molecule in microvesicles of natural phospholipids from non-GMO sunflower lecithin, mimicking cell membrane structure and protecting glutathione throughout digestion — resulting in markedly improved intestinal absorption and easier passage across cell walls.

Dynveo’s liposomal technology encapsulates reduced glutathione in sunflower phosphatidylcholine microvesicles, structurally similar to human cell membranes, protecting the active molecule from gastric degradation and favouring direct passage across the intestinal barrier. The phospholipids come from non-GMO sunflower, with no chemical solvents or irradiation — a 100% natural formulation.

Take 1 to 2 capsules a day with a large glass of water, preferably away from meals — ideally in the morning on an empty stomach or between meals. One capsule (150mg) suits daily antioxidant support; two capsules (300mg) can be considered during periods of increased stress, pollutant exposure or intensive recovery.

Does not replace a varied, balanced diet or healthy lifestyle. Pregnant or breastfeeding women should consult their doctor before supplementing. Prior medical advice is recommended if on medication. Store in a cool, dry place away from direct light and heat, out of reach of young children.

What’s the difference between reduced and oxidised glutathione?

Reduced glutathione (GSH) is the biologically active form, able to directly neutralise free radicals; oxidised glutathione (GSSG) is the inactive form produced after GSH has done its job. Only reduced glutathione is relevant for supplementation.

Can I combine liposomal glutathione with other supplements?

It pairs well with vitamin C, which helps recycle oxidised glutathione back to its active reduced form, and with NAC, a direct glutathione precursor.

How long does a bottle last?

60 capsules cover two months at one capsule a day (150mg), or one month at two capsules a day (300mg).
