“Before discussing its benefits, it’s important to understand how glutathione is actually produced inside your cells.”
Glutathione (GSH) is not simply absorbed like a typical nutrient. It is synthesized inside cells through a tightly regulated two-step enzymatic process requiring three amino acids: glutamate, cysteine, and glycine.
The first and rate-limiting step involves the binding of glutamate and cysteine, catalyzed by the enzyme glutamate-cysteine ligase. The second step adds glycine to complete the formation of glutathione.
Because this process occurs intracellularly, precursor availability—particularly cysteine—plays an important role in supporting natural glutathione production.
