What Is Grape Skin Powder Extract Resveratrol / Polyphenol?
Grape Skin Powder Extract is a natural plant-derived ingredient obtained from the outer skin of grapes (Vitis vinifera L.). The grape skin is one of the richest natural sources of antioxidant compounds, making it highly valuable in nutritional and health-related applications.
The key bioactive components include:
Resveratrol
Grape Polyphenols
Anthocyanins
Flavonoids
Natural antioxidants
These compounds work synergistically to help protect cells from oxidative stress and environmental damage, making grape skin extract a widely used ingredient in modern wellness formulations.
Botanical Source and Composition
Grape skin extract is derived from carefully selected grape varieties known for their high antioxidant content. Within the grape structure:
The pulp mainly provides sugars and moisture
The seeds are rich in proanthocyanidins
The skin contains the highest concentration of resveratrol and polyphenols
Because of this unique distribution, grape skin has become a preferred raw material for antioxidant extraction.
