Because vitamin C is water-soluble, it washes out of your body when you urinate. Therefore, it is important to get several doses of vitamin C a day. To get enough vitamin C, I recommend taking at least two, usually three, doses of vitamin C daily. I do this by combining food and supplements. In the morning, I take a multivitamin containing 500 milligrams (mg) of vitamin C, have an orange or grapefruit at lunch, and take a multivitamin containing 500 mg of vitamin C with dinner (that multivitamin also has 200 international unit (IU) of vitamin E for breakfast and dinner), just to make sure I'm getting enough.
