Ascorbic Acid, better known as Vitamin C, is found in many vegetables and fruits, such as potatoes, broccoli, kiwi, tomatoes, green peppers, cantaloupe, strawberries, and the most famous oranges.  When these vegetables and fruits are cooked the Vitamin C dissolves in cooking water, so try to serve the food with the cooking water if possible.  Orange juice is usually bought frozen, but the best way to get orange juice is by freshly squeezed oranges.  It preserves most of the Vitamin C.
              Vitamin C helps people stay healthy and also helps reduce bruising, by making the small blood vessels less fragile.  The Daily Recommended  Dietary Allowance for Vitamin C is 60 milligrams.  If you think your lacking from Vitamin C and you eat right, then you might think about taking Vitamin C supplements.
