Does Grape Seed Extract Work?
Grape seed extract products are supposedly beneficial for treating a wide variety of conditions, but does grape seed extract work? Studies suggest that the supplement may work for treating poor circulation in the legs, as well as helping to relieve stress on the eyes due to glare. Not much is known about the effectiveness of grape seed extract for other uses.
Does Grape Seed Extract Really Work?
As with most dietary supplements, grape seed extract is claimed to work for a variety of different uses. However, does it really work? This article will address the effectiveness of grape seed extract for various uses, including:
- Treating the following conditions:
- Atherosclerosis (hardening of the arteries)
- High blood pressure (hypertension)
- High cholesterol
- Poor circulation (chronic venous insufficiency)
- Diabetes complications (such as nerve or eye problems)
- Macular degeneration
- Swelling after an injury or surgery
- Cirrhosis of the liver
- Hay fever or other similar allergies
- Preventing cancer
- Promoting wound healing
- Preventing dental cavities (dental caries)

Scientific Evidence for Grape Seed Extract
A few studies suggest that grape seed extract may really work for treating poor circulation in the legs (a condition called chronic venous insufficiency). It may help relieve symptoms and might even reduce leg swelling. One small study also suggested taking grape seed extract might help relieve stress on the eyes due to glare.
Studies suggest that the supplement probably does not work for hay fever (it does not seem to reduce symptoms at all).
There is not enough scientific evidence to suggest that grape seed extract really works (or does not work) for other uses. More studies (especially large, high-quality studies) are necessary before the supplement can be recommended for such uses.
