Question

Too much vitamin C: Harmful?

Is it possible to take too much vitamin C?

Answer

from Katherine Zeratsky, R.D., L.D.

Vitamin C (ascorbic acid) is an essential nutrient. Still, it's possible to have too much vitamin C.

Vitamin C is a water-soluble vitamin that supports normal growth and development. Vitamin C also helps your body absorb iron. Because your body doesn't produce or store vitamin C, it's important to include vitamin C in your diet. 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. Although too much dietary vitamin C is unlikely to be harmful, megadoses of vitamin C supplements may cause:

• Diarrhea
• Nausea
• Vomiting
• Heartburn
• Abdominal bloating and cramps
• Headache
• Insomnia
• Kidney stones

Remember, for most people, a healthy diet provides an adequate amount of vitamin C.
