Key Clinical Takeaways (Answer-First)
- Grape seed extract contains 95% oligomeric proanthocyanidins (OPCs), antioxidants 20x stronger than vitamin C.
- The stria vascularis of the inner ear is uniquely susceptible to lipid peroxidation from acoustic trauma.
- OPCs enhance endothelial nitric oxide release, increasing capillary blood flow velocity to the cochlea.
- Neurozen supplies 75 mg of standardized grape seed extract per daily dropper.

The High Metabolic Fragility of the Cochlea
The sensory structures of the inner ear consume vast quantities of oxygen and glucose relative to their tiny physical volume. When exposed to acoustic noise or vascular insufficiency, mitochondrial free radicals overwhelm cellular defenses, causing irreversible hair cell death.
Why Oligomeric Proanthocyanidins (OPCs) Excel
Grape seed extract is standardized to deliver 95% oligomeric proanthocyanidins (OPCs). These polyphenols possess extraordinary free-radical scavenging capacity, protecting delicate cell membrane lipids from lipid peroxidation and stabilizing capillary basement membranes.
Endothelial Nitric Oxide & Acoustic Perfusion
Beyond antioxidant defense, OPCs promote endothelial nitric oxide synthase (eNOS) activation. This stimulates localized microvascular vasodilation in the spiral modiolar artery, preventing acoustic hypoxia in hard-working auditory hair cells.
Dosing in Neurozen
Neurozen includes 75 mg of standardized grape seed extract, delivering robust antioxidant protection to defend delicate auditory hair cells against environmental wear.
