Is too much vitamin C harmful?
Your body needs vitamin C, but megadoses can cause many digestive problems. Find out how much of the nutrient you really require.
While vitamin C (ascorbic acid) is an essential nutrient, it’s possible to have too much of it.
Vitamin C is a water-soluble vitamin that supports normal growth and development and 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, an orange or a cup of strawberries, chopped red pepper, or broccoli provides enough vitamin C for the day.
For adults, the recommended daily amount 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 might cause:
- Diarrhea
- Nausea
- Vomiting
- Heartburn
- Abdominal cramps
- Headache
- Insomnia
