Glutathione Synthesis and Redox Cycle

Glutathione (GSH) is the cell's master antioxidant; reduced by GR using NADPH and oxidized by GPx while quenching ROS.

A free, animated glutathione synthesis and redox cycle you can read here or embed on any website, from Scrollchart.

Your body builds glutathione from three amino acids, but cysteine is always the bottleneck. NAC supplements provide cysteine directly, letting your cells ramp up production of this critical protector.

Source & accuracy

This glutathione synthesis and redox cycle is an editorial illustration built to represent the concept accurately. Where it shows figures, they are typical or representative values chosen to make the relationship clear, not a single underlying dataset. The diagram and its explainer are reviewed and maintained centrally, and updated over time as understanding improves.

The cell's recyclable antioxidant

Glutathione is a tripeptide of glutamate, cysteine, and glycine, with cysteine providing the reactive thiol group. In its reduced form (GSH) it neutralizes reactive oxygen species. Glutathione peroxidase (GPx) uses GSH to reduce hydrogen peroxide and lipid peroxides to water and alcohols, and in doing so GSH is oxidized to its disulfide form, GSSG.

Regeneration powered by NADPH

To keep working, the cell must regenerate GSH from GSSG. Glutathione reductase (GR) performs this step using NADPH as the electron source, much of which comes from the pentose phosphate pathway. The ratio of GSH to GSSG is a common indicator of a cell's redox state. While glutathione is central to antioxidant defense, oral glutathione supplements are poorly absorbed and the evidence that they raise tissue levels or treat disease is limited.
