Mechanism

Combination that restores glutathione synthesis. Age-related glutathione deficiency is driven by glycine and cysteine precursor depletion, not enzyme dysfunction. GlyNAC corrects oxidative stress, mitochondrial dysfunction, inflammation, and insulin resistance in older adults.

Contraindications

  • Active stomach ulcer (NAC)
  • Asthma (NAC may cause bronchospasm in rare cases)
B

Supplements

Mechanism

Redox-active quinone that supports mitochondrial biogenesis signaling and resilience under oxidative load.
