biosynthesis of glutathione is synthesized from Synthesis Explained: How Your Body Builds Its Master Antioxidant Amino Acid Derivatives: Neurotransmitters, Nitric – Frontiers | Plant Glutathione Biosynthesis:

Then, in the early 1990s, a Croatian researcher at the University of Zagreb named Petar Sikiri did something that would eventually shake the biohacking world

Arginine is the primary substrate for nitric oxide synthase, the enzyme that produces nitric oxide in the body

Glutathione is often referred to as the bodys master antioxidant because of its important role in supporting normal immune function, cellular metabolism, and overall cellular regulation

However, significant challenges remain, including the synthesis of stable tripeptides with good tissue penetration, insufficient understanding of their mechanisms of action, the scarcity of studies in larger animal models and human trials, and the lack of direct head-to-head comparisons with larger peptides [75, 95]
