Drinking carrot juice provides you with several beneficial nutrients, including antioxidants. A 2011 study published in the “Nutrition Journal” reports that carrot juice increases the antioxidant status in your body, which may help protect you against cell damage and heart disease.

Carrot juice is not a high-calorie drink, but it does contain more calories than raw carrots. According to the USDA’s National Nutrient Database, while one portion -- or 1 cup -- of carrot juice provides 94 calories, 1 cup of grated carrots contains just 45 calories. The Dietary Guidelines for Americans 2010 suggest eating 2.5 cups per day from the vegetables group, which includes vegetable juices, when consuming a 2,000-calorie meal plan.
Although 1 cup of carrot juice does provide about 2 grams of dietary protein, the majority of the calories in carrot juice are from carbohydrates. The USDA reports that 1 cup of carrot juice contains about 22 grams of total carbohydrates -- including 2 grams of dietary fiber. The Dietary Guidelines for Americans 2010 suggest men consume 38 grams of fiber and women eat at least 25 grams of fiber each day to help reduce chronic-disease risk factors.
One cup of carrot juice contains 2,256 micrograms of vitamin A, which exceeds the vitamin A recommended dietary allowance -- or RDA -- for adults. The Office of Dietary Supplements reports that the tolerable upper intake level, or maximum safe amount, of vitamin A is 3,000 micrograms per day. Therefore, if you drink 2 cups of carrot juice, you’re actually exceeding the vitamin A tolerable upper intake.
While carrot juice is known for its vitamin A content, it provides other essential nutrients as well. Carrot juice is an excellent source of potassium and vitamins C, E and K. One cup of carrot juice contains 689 milligrams of potassium and almost 3 milligrams of vitamin E -- the adequate intake level for potassium is 4,700 milligrams per day, while the RDA for vitamin E is 15 milligrams daily for adults, notes the Institute of Medicine.
