NAC is a stable, bioavailable form of the amino acid L-Cysteine — and most critically, the \u003cstrong\u003erate-limiting precursor to glutathione\u003c\/strong\u003e — the body’s master antioxidant and primary intracellular detoxification molecule. Every cell in your body produces glutathione, but its synthesis is limited by cysteine availability. By supplying NAC, this supplement directly fuels glutathione production in the liver, lungs, kidneys, and brain — supporting cellular defense, detoxification, and resilience at their most fundamental level. Enhanced with \u003cstrong\u003eSelenium\u003c\/strong\u003e — an essential cofactor for glutathione peroxidase enzymes — this formula maximizes the functional activity of the glutathione system for comprehensive free radical protection.\u003c\/p\u003e\u003ch2\u003eThe Glutathione Connection\u003c\/h2\u003e\u003cp\u003eGlutathione (GSH) is often called the \u003cstrong\u003e“master antioxidant”\u003c\/strong\u003e because unlike vitamin C or E which are consumed when neutralizing free radicals, glutathione is continuously \u003cem\u003erecycled\u003c\/em\u003e by the body.
