65 mg -90 milligrams: For most people, a large orange, 1 cup (about 165 grams) of sliced strawberries, chopped red pepper or broccoli provide enough vitamin c for the day. Any extra vitamin c will simply be flushed out of your body in your urine. For adults, the recommended dietary reference intake for vitamin c is 65 to 90 milligrams (mg) a day, and the upper limit is 2, 000 mg a day.
