Grape seed extract

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 which are not supported by sufficient medical evidence.[1]

Research and potential health effects

GSE is being investigated for its potential antibacterial properties.[2]

A meta-analysis of randomized controlled trials concluded that "grape seed extract appears to significantly lower systolic blood pressure and heart rate, with no effect on lipid or C-reactive protein levels."[3]

The US National Center for Complementary and Integrative Health reported that oral administration of grape seed extract was well tolerated in people over 8 weeks, although there are no studies yet indicating its effectiveness in treating diseases.[1]

Side effects may include itchy scalp; dizziness, headache, high blood pressure or nausea.[1]
