Vesilute
Summary
VIP is a 28-amino acid neuropeptide with profound anti-inflammatory, vasodilatory, and immunomodulatory effects. It plays a critical role in gut motility, circadian rhythm, and immune tolerance. Used therapeutically for CIRS (Chronic Inflammatory Response Syndrome), MCAS, and inflammatory conditions.
Vesilute is a tetrapeptide bioregulator (Lys-Glu-Asp-Leu) developed by Professor Vladimir Khavinson, tissue-specific for the retina and visual system. It supports retinal cell function, promotes normalization of photoreceptor protein synthesis, and is studied for age-related macular degeneration (AMD), retinal aging, and vision preservation in the elderly.

4x daily
Daily for 10–30 days
Key Benefits
  • Potent anti-inflammatory for CIRS and mold illness
  • Improves pulmonary hypertension symptoms
  • Regulates gut motility and IBS symptoms
