Why do people take grape seed extract?

There’s strong evidence that grape seed extract is beneficial for a number of cardiovascular conditions. Grape seed extract may help with a type of poor circulation (chronic venous insufficiency) and high cholesterol. Grape seed extract also reduces swelling caused by injury and helps with eye disease related to diabetes.

Many people are interested in grape seed extract because it contains antioxidants. These are substances that protect cells from damage and may help prevent many diseases. However, it’s still too early to say whether the antioxidant properties of grape seed extract really benefit people. Researchers are studying grape seed extract to see if it might lower the risks of some cancers. For now, the evidence is not clear.

Grape seed extract has been studied for use in many other conditions -- ranging from PMS to skin damage to wound healing -- but the results have been inconclusive.
