Vitamin E is a powerful lipid soluble antioxidant, required for maintaining the integrity of cell membrane of mucus membranes and skin by protecting it from harmful oxygen-free radicals.
In addition, the fruits contain good amounts of minerals like calcium, copper, iron, manganese, and zinc. Further, they are small sources of B-complex vitamins such as niacin, choline, and pantothenic acid.
