Americans meet about 90 percent of their vitamin C needs by consuming fruits and vegetables, with orange and/or grapefruit juice being the most popular source in the diet. One serving of either juice will just about meet an adult’s daily needs. Tomatoes, peppers, potatoes, broccoli, oranges, and cantaloupe are also excellent sources.

When it comes to vitamin C, some is good, but too much could cause problems. The Tolerable Upper Level for vitamin C has been set at 2,000 milligrams to avoid the intestinal discomfort that excessive amount of the vitamin can cause. 
Too much vitamin C can also lead to the formation of kidney stones in individuals with a history of kidney disease.
