What is Grape Seed Extract?

Grape Seed Extract is a powerful antioxidant derived from the seeds of grapes (Vitis vinifera). It is one of the richest sources of oligomeric proanthocyanidins (OPC), which are potent flavonoid compounds known for their exceptional free radical scavenging ability.

Key Benefits

  • Cardiovascular Health: Supports healthy blood vessels, circulation, and heart function
  • Skin Health: Protects collagen and elastin, promotes youthful-looking skin
  • Cognitive Support: Crosses blood-brain barrier to protect neural tissues
  • Eye Health: Supports retinal health and visual function

Available Specifications
