Grape seed extract

Grape seed extract is an industrially-produced derivative of grape seeds, found to be rich in antioxidants.

What are its health benefits?

Grape seed extract has been associated with a range of possible therapeutic properties including wound healing, and assisting in the management of conditions such as macular degeneration, high cholesterol, nerve damage and poor circulation.

While evidence is emerging of its health benefits, many still need to be supported with further study. 

Grape seed extract supplementation may have the following benefits:

  • Aids the wound healing process
  • Supports bone health when taken in conjunction with calcium
  • Assists in the protection of blood vessels from becoming damaged
  • Assists in reducing swelling (edema) that occurs after injury or surgery (for example, breast cancer surgery)
  • May assist with prevention of a decline in memory and thinking abilities associated with ageing
