Evidence LevelStrongStrong

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)

Mechanism

Endocannabinoid-like lipid that activates PPAR-alpha and indirectly enhances endocannabinoid tone. Potent anti-inflammatory and analgesic without acting directly on CB1/CB2. Reduces mast cell activation, neuroinflammation, and chronic pain.

Contraindications

  • None established at standard doses
