Grapes are a source of vitamins, with each cup providing 13.4 micrograms of vitamin K, or 17 percent of the daily value; 3.7 milligrams of vitamin C and 0.09 milligrams of thiamine, or six percent of the daily value for each of the latter two nutrients; and 0.1 milligrams of vitamin B-6, or five percent of the DV.hile red seedless grapes aren't a great source of minerals, they do provide 176 milligrams of potassium, or five percent of the DV, per one-cup serving, as well as smaller amounts of magnesium, zinc, iron, calcium and phosphorus.
Minerals. A serving of green seedless grapes is a healthy source of potassium and iron. Potassium aids in organ, tissue, muscle, cell and heart functions, and you need 4,700 milligrams each day to support these bodily systems. One cup of green grapes supplies 288 milligrams toward that goal.
