The Vitamin C Foundation recommends that all Americans get the Vitamin C available in five oranges every day to maintain a functional immune system.
Owen Fonorow at the Vitamin C Foundation states that the cure for all viruses is to build up our own immune systems. Vaccines assist the immune system, but it's the immune system that's essential. People only die from a virus when the immune system is compromised.
Vitamin C is essential for the immune system. You must keep a certain level of Vitamin C in your body to have a working immune system. If you can't eat five oranges a day, or five other fruits high in Vitamin C, 250mg of Vitamin C supplements will give your body what it needs to keep an average person's immune system going strong. In cases of impaired immunity, caused by chronic diseases or poor nutrition, the foundation recommends higher doses of at least 3000mg daily.
