Grape Seed Extract is a nutritional supplement derived from the seeds of the grape plant (Vitis vinifera).
Grape Seeds are rich in chemicals called proanthocyanidins that exhibit antioxidant properties.
Antioxidants have the ability to neutralise harmful chemicals called free radicals, which can contribute to premature ageing and are involved in the development of many diseases, including arthritis, atherosclerosis, Alzheimer's disease, Parkinson's disease and cancer.
One clinical trial demonstrated that the antioxidant action of Grape Seed Extract is more powerful than the effect of vitamins C, E and beta-carotene.
- The main action of Grape Seed Extract is its ability to prevent harmful cell changes in the body that could otherwise progress to cancer.
- Grape Seed Extract has been found to protect the body against damage caused by ultraviolet (UV) light which can harm the membranes surrounding cells in the body resulting in DNA damage.
- Proanthocyanidins derived from Grape Seeds possess cardio-protective properties.
The antioxidant compounds found in red wine are known as polyphenols and are different from those found in Grape Seed Extract. The antioxidant potential of both red wine and Grape Seeds have been scientifically established.
As Grape Seed Extract and wine antioxidant compounds are chemically distinct, the antioxidant activities cannot be the same.
