Vitamins and Nutrients in Grapes

There are several key vitamins and nutrients in grapes that are vital for the health and care of your body, which you can get simply by adding grapes to your diet.

Vitamin K

Grapes are an excellent source of Vitamin K, a fat-soluble vitamin known for its role in helping blood clot properly. Vitamin K is also essential to building strong bones and preventing heart disease.


Whole or chopped grapes contain a small amount of fiber. Dietary fiber, as part of an overall healthy diet, helps reduce blood cholesterol levels and may lower the risk of heart disease. Keep in mind that fruit juices contain little or no fiber.


Polyphenols are micronutrients that play a role in the prevention of degenerative diseases. Resveratrol, a type of polyphenol, is found in the skin of green, red and black grapes. Studies suggest that it may offer even more health-promoting benefits.

Antioxidants in Grapes

Antioxidants maintain health by defending against damaging free radicals that can harm healthy cells. Grapes have been shown to increase the activity of these antioxidant defense pathways including the production of glutathione, the most abundant cellular antioxidant in the heart. This is another of the many health benefits of grapes.
