L-Glutathione 500mg | 99% Pure Reduced Form | Fermentation Derived | Antioxidant | 60 Vegan Capsules

Each vegan capsule delivers 500mg of reduced L-Glutathione (GSH) 99% pure, produced by pharmaceutical-grade microbial fermentation. Reduced glutathione is the biologically active antioxidant form: the free thiol group on cysteine is available to donate electrons and neutralize free radicals. The most abundant intracellular antioxidant in the human body, now in a clean, high purity capsule format.

Who This Is For

• Adults seeking a direct, high-purity glutathione supplement in the active reduced GSH form
• Those who want fermentation derived glutathione that is vegan, non-GMO, and Health Canada licensed
• Those who prefer supplementing with the finished tripeptide directly rather than a precursor such as NAC
• Those seeking liver antioxidant support from the body’s primary intracellular antioxidant

What Is Glutathione and Why Does It Matter?

Glutathione (GSH) is a tripeptide composed of three amino acids: glutamate, cysteine, and glycine. It is synthesized in every cell of the body and is the most abundant intracellular antioxidant in the human body. The liver the body’s primary detoxification organ has the highest glutathione concentration of any tissue, reflecting its central role in neutralizing reactive metabolites and toxins.

Glutathione works by donating electrons from the thiol group on its cysteine residue to neutralize free radicals and reactive oxygen species. When oxidized it becomes GSSG, which is then converted back to active GSH by glutathione reductase a continuous recycling system that makes glutathione one of the most efficient antioxidant mechanisms in the body.

Reduced GSH vs. Oxidized GSSG: Why the Form Matters

Reduced glutathione (GSH) has a free thiol group (SH) on its cysteine residue the active site that donates electrons to neutralize free radicals. This is the biologically active antioxidant form. Oxidized glutathione (GSSG) has already donated its electrons and must be converted back to GSH by glutathione reductase before it can function as an antioxidant again. This formula provides glutathione exclusively in the reduced GSH form active and ready to work from the moment it is absorbed.

Fermentation-Derived: Pharmaceutical-Grade Purity

L-Glutathione in this formula is produced by microbial fermentation the same biosynthetic process used to produce pharmaceutical-grade amino acids and vitamins. The resulting glutathione is purified to 99% purity and is chemically identical to the glutathione produced endogenously in every human cell. It is not derived from animal sources and is suitable for vegans and vegetarians.

Glutathione as the Master Intracellular Antioxidant

Glutathione operates in the aqueous intracellular environment where many oxidative reactions occur. It directly neutralizes reactive oxygen and nitrogen species, regenerates the oxidized forms of vitamin C and vitamin E (restoring their antioxidant activity), and serves as a cofactor for glutathione peroxidase enzymes that reduce hydrogen peroxide and lipid peroxides. In the liver, glutathione S-transferase enzymes conjugate GSH to reactive metabolites and toxins, making them water-soluble for excretion a process central to Phase II detoxification.

Glutathione vs. NAC: Direct vs. Precursor

NAC (N-Acetyl-L-Cysteine) supports glutathione levels indirectly by providing cysteine the rate limiting amino acid for glutathione synthesis and the body uses that cysteine to synthesize its own glutathione. This formula provides the finished tripeptide directly as reduced GSH at 500mg per capsule, bypassing the synthesis step entirely.

Storage

Store in a cool, dry place away from direct sunlight and moisture. Keep the bottle tightly sealed after each use. Glutathione is sensitive to heat, light, and moisture proper storage preserves potency. Do not use if the seal is broken or missing. Keep out of reach of children.

Cautions

If you are undergoing cancer treatment, consult your oncologist before use  glutathione may interact with certain chemotherapy drugs. Individuals with asthma should consult a healthcare practitioner before use. Consult a healthcare practitioner before use if you are pregnant or breastfeeding, or taking medications. Keep out of reach of children.
