Grapefruit Vitamin C Content. One serving of grapefruit is half of a medium grapefruit, which is 4 inches in diameter. Each serving contains 44 milligrams of vitamin C, which is 73 percent of the daily value of 60 milligrams for people following a 2,000-calorie diet. If you eat an entire grapefruit, you will have consumed the recommended amount of vitamin C for the day. This makes grapefruit an excellent source of vitamin C.
