Benfotiamine

Supplements

Mechanism

Lipid-soluble thiamine derivative that improves cellular thiamine availability and helps reduce advanced glycation stress in high-glucose environments.

Contraindications

  • None established at standard doses

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)
