Grape Seed Extract

Grape seed extract (GSE) is a concentrated form of the beneficial compounds found in the seeds of grapes (Vitis vinifera). It is one of the richest natural sources of antioxidants, particularly oligomeric proanthocyanidins (OPCs), which are much stronger than vitamins C and E in neutralizing free radicals.

Because of this, grape seed extract is widely used as a dietary supplement for heart health, skin anti-aging, circulation, and inflammation support.
