The benefits
L-Glutathione
L-Glutathione, a powerful antioxidant at the heart of our cellular defense. It is the bioactive form of glutathione, naturally present and used by our body to fight against free radicals and oxidative stress.
High availability
Our L-Glutathione is designed for maximum bioavailability. It is essential for cellular detoxification, helping to protect the integrity of our cells.
Naturally produced by the body
L-Glutathione plays a key role in nutrient metabolism, the regeneration of vitamins C and E, and the modulation of the immune response.
optimal dosage
Each serving of our dietary supplement provides an optimized amount of L-Glutathione, ensuring you daily antioxidant support for cellular well-being.
Glutathione, in its reduced form.
Glutathione is a molecule the body naturally makes, involved in cellular antioxidant defence. The Hexagon® formula provides 300 mg in its reduced form, GSH.

The full composition
Your body makes glutathione from three amino acids: cysteine, glycine and glutamate. Its reduced form, called GSH, participates in the balance of oxidation–reduction reactions. Hexagon® Glutathione contains this precisely identified form.

The scientific context
Oral glutathione, studied over time.
A six-month controlled trial in 54 adults observed an increase in blood glutathione with daily intakes of 250 or 1,000 mg. Such measurements help researchers study glutathione levels in different compartments of the body.
The trial used another formulation and other doses. A four-week trial found no significant effect. The findings do not predict an individual benefit from the finished Hexagon® 300 mg product.
NAC and glutathione: two different approaches.
Both products relate to glutathione, but they provide different substances. Understanding that difference is more useful than comparing milligram amounts alone.
NAC · 600 mg per capsule
A derivative of cysteine. The body uses cysteine, together with glycine and glutamate, to synthesise glutathione.
Reduced glutathione · 300 mg per capsule
The GSH form of glutathione is present in the formula. It is different from NAC, which is a precursor.
600 mg NAC does not correspond to 600 mg of glutathione produced. These amounts do not establish equivalent effectiveness or the superiority of either product.
One capsule a day.
Pair your intake with a familiar meal. At one daily capsule, the 60-capsule bottle provides 60 days, following the product directions.
