For a healthy adult female, the recommended daily amount of Vitamin C is 75 milligrams (mg). If you are pregnant or breastfeeding, this recommendation increases to 85 mg and 120 mg daily, respectively. You can easily meet this goal by eating a diet rich in citrus fruits, berries, tomatoes, and bell peppers. If you choose to take a supplement, keep your total intake below the safe upper limit of 2,000 mg per day to avoid mild digestive upset. For most people, a balanced diet provides all the Vitamin C they need.
