Buy Reduced Glutathione: the body’s master antioxidant
Jarrow Formulas’ Reduced Glutathione 500mg provides glutathione in its reduced form (GSH), the only biologically active form directly usable by the body. Available at our Paris shop, with Click & Collect and delivery across France and Europe. Best-before: March 2027.
Why the reduced (GSH) form matters
Glutathione is a tripeptide of cysteine, glutamic acid and glycine, present in every cell and often called the body’s “master antioxidant” for its central role in neutralising free radicals and regenerating other antioxidants like vitamins C and E. It exists as reduced (GSH, active) and oxidised (GSSG, inactive) forms; supplementing with reduced glutathione supplies the active form directly. Natural production declines with age, stress, pollutant exposure and lifestyle — recent research suggests oral supplementation at 250–1,000mg/day can help raise plasma and intracellular GSH levels.
Glutathione’s roles in the body
As the main intracellular antioxidant, glutathione protects cells from free radical damage, particularly in high-metabolic-activity organs like the liver, kidneys and lungs. It plays a key role in phase II liver detoxification, conjugating with toxins and drug metabolites to aid elimination. It regenerates oxidised vitamin C and supports vitamin E recycling, contributes to immune cell function, and helps protect cellular DNA from oxidative damage.
How to use & precautions
Take 1 capsule a day, preferably on an empty stomach or between meals (at least 30 minutes before eating or 2 hours after) for optimal absorption. Pairs well with vitamin C, alpha-lipoic acid or NAC. A 2-month course (60 capsules at 1/day) is generally recommended to see significant results.
Does not replace a varied, balanced diet or healthy lifestyle. Do not exceed the recommended daily dose. Keep out of reach of young children. Consult a healthcare professional before use if pregnant, breastfeeding, on medication or with a specific health condition. Store in a cool, dry place away from direct light and moisture.
Frequently asked questions
What’s the difference from liposomal glutathione?
Reduced glutathione (GSH) is the standard active form, here in vegetable capsules at a generous 500mg dose; liposomal glutathione is encapsulated in lipid micro-vesicles that may further protect it from stomach degradation. Both have their merits.
Can I take glutathione continuously?
A common approach is courses of 2–3 months followed by a month’s break; some choose longer-term use, particularly with chronic oxidative stress exposure. Consult a healthcare professional to define the best protocol for you.
Does glutathione affect skin?
Glutathione is increasingly studied for its role in supporting healthy, radiant skin, as a major antioxidant protecting skin cells from oxidative stress linked to premature ageing.
