By all means, keep taking vitamin C! I've been taking 4,000 mg a day for 13 years now, and have not had a cold during that time. Vitamin C aids in the healing process of cuts, scratches and even surgery. More and more good things are being found out about it. Beware though, because the drug companies want to take C, as well as all supplements out of our reach. Why? Because healthy people don't need to buy their drugs.
