A cup of American-type grapes such as Concord has about 62 calories, 0.66 mg of manganese (29% DV) and 13 mcg of vitamin K (11% DV). That makes it a good source of vitamin K. (USDA) The NIH Office of Dietary Supplements says the body uses manganese to make energy and protect cells from damage, and needs it for strong bones and a healthy immune system.
