What is Grape Seed Extract?

Common Names: grape seed extract, grape seed

Latin Name: Vitis vinifera

Grape seed extract is an industrial derivative of whole grape seeds.

The extract contains proanthocyanidins.[1] In alternative medicine, grape seed extract is sold in dietary supplement form and claimed to have numerous health benefits.[1]

Since ancient Greece, people have used grapes, grape leaves, and sap for multiple health purposes, leading to the development of Grape seed extract in the 1970s.

Today, grape seed extract is used as a dietary supplement for various conditions, including for venous insufficiency (when veins have problems sending blood from the legs back to the heart), to promote wound healing, and to reduce inflammation.



What are the benefits of Grape Seed Extract?

Grape seed extract is composed of a complex mixture of flavonoids, Vitamin E, linoleic acid, and phenolic procyanidins.[3] These compounds can also be found in the skins and juices of the fruit. The active agents of extract are mostly polyphenols or OPCs (oligomeric procyanidins), which is usually the commercial reason why grape seeds are being extracted. Proanthocyanidins and catechins are the potent antioxidants in grape seeds that are believed to be 20 times greater than vitamin E and 50 times greater than vitamin C.[4]


Why take Grape Seed Extract?

Grape seed extract is used for conditions related to the heart and blood vessels, such as atherosclerosis (hardening of the arteries), high blood pressure, high cholesterol, and poor circulation.

Other reasons for the use of grape seed extract include complications related to diabetes, such as nerve and eye damage; vision problems, such as macular degeneration (which can cause blindness); and swelling after an injury or surgery.

Grape seed extract is also used for cancer prevention and wound healing.[5, 6]
