Grape seeds are rich in powerful antioxidants and natural plant compounds called oligomeric proanthocyanidin complexes (opcs). Opcs are most well known for their antioxidant activity, which means, at the very least, grape seed may help to destroy free radicals in your body, which in turn may help you avoid premature aging and certain chronic diseases.

Biochemical and preliminary clinical studies have demonstrated

potential biological properties of grape seed oligomeric procyanidins. For example, laboratory tests indicated a potential anticancer effect from grape seed extract. According to the American Cancer Society, "there is very little reliable scientific evidence available at this time that drinking red wine, eating grapes, or following the grape diet can prevent or treat cancer in people".Grape seed oil from crushed seeds is used in cosmeceuticals and skincare products for perceived health benefits. Grape seed oil contains tocopherols (vitamin E) and high contents of phytosterols and polyunsaturated fatty acids such as linoleic acid, oleic acid, and alpha-linolenic acid.
