What is Grape Seed Extract?

Grape Seed Extract is a substance that is rich in flavonoids, Vitamin E, linoleic acid, and polyphenols. Unsurprisingly, the substance is extracted from the seeds of grapes.

There is some data which suggests that grape seed extract may contain disease-preventing effects. In particular, the anti-oxidents that the substance is rich in may help with this. This data is of a case study nature, however, and has yet to be widely accepted within the scientific community. In essence, the health effects have yet to be proven conclusively in the lab.

Grape Seed Extract is often administered in (oral) pill form, typically in 50mg and 100mg doses per pill. The substance can cause side effects such as nausea and headache, among effects.
