CategorySupplementsSupplements
Standard Dose
Timing
Cycle Duration
Evidence LevelStrong (venous insufficiency — prescription in EU)Strong

Mechanism

Micronized flavonoid fraction that strengthens venous tone, reduces capillary permeability, and improves lymphatic drainage. Inhibits prostaglandin and thromboxane synthesis. Used as prescription venotonic in Europe for chronic venous insufficiency and hemorrhoids.

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)
