Grape seeds are small, hard, and round seeds that are found inside grapes. They are typically brown or dark brown in color and have a slightly bitter taste. Grape seeds are rich in antioxidants, including proanthocyanidins, which have been linked to a variety of health benefits, including reducing inflammation, improving cardiovascular health, and promoting healthy aging.

Grape seeds are often used in dietary supplements, cosmetics, and skincare products due to their high antioxidant content. They are also sometimes used in cooking, particularly in the production of grape seed oil, which is used as a cooking oil and a base for salad dressings.

In addition to their antioxidant properties, grape seeds are also a good source of fiber and contain a variety of essential minerals, including magnesium, potassium, and calcium. They are generally considered safe for consumption in moderate amounts and can be a healthy addition to a balanced diet.
