NAC (N-Acetylcysteine): Glutathione Restoration and Clinical Evidence
Evidence analysis of N-acetylcysteine (NAC): reliable glutathione precursor with proven antioxidant effects. Early signals in Parkinson's and cognition, but NO strong evidence for protein clump clearance, Alzheimer's treatment, or Long COVID recovery in humans. Ferroptosis inhibition relevant to spike-induced microglial death, disulfide bond disruption for spike aggregates, and MMP-9/BBB protection mechanisms.
