Description
"N-Acetyl-L-Cysteine" (NAC) is a supplement derived from the amino acid L-cysteine, recognized for its role in biochemical processes. Glutathione production is directly influenced by NAC, supporting detoxification pathways and cellular protection. Respiratory function, liver enzyme activity, and neurological balance are closely linked to its biochemical role. Many formulations utilize NAC in metabolic and immune-focused applications. Its distinct sulfur-based composition makes it a fundamental element in targeted formulations for oxidative defense and cellular resilience.
