Vitamin C does more than just ward off the sniffles. It can help heal wounds, improve the absorption of iron, and protect cells from damage by free radicals. Eating foods rich in vitamin C (not supplements) may also help lower your risk of lung, breast, and colon cancers.
Here’s how much vitamin C you should aim for: Women over age 19 need about 75 mg a day, and men need 90 mg. During pregnancy, women should up their intake to 85 mg of vitamin C a day, and then get 120 mg of vitamin C a day while breastfeeding.
