Grape seed extract is an industrial derivative of grape seeds, extremely rich in antioxidants and oligomeric proanthocyanidin complexes (OPCs).
The extract has been linked to a wide range of possible therapeutic properties including healing wounds and treating conditions such as high cholesterol, atherosclerosis, macular degeneration, poor circulation, nerve damage, as well as preventing cancer.
Although many of these health claims are still not completely backed up by "high quality" studies, strong evidence is beginning to emerge on grape seed extract's extensive health benefits.
Grape seed extract is available as a dietary supplement in either a liquid form, tablets or capsules. Supplements generally contain between 50 to 100 mg of the extract.
