Does vitamin C help prevent the common cold?

While you can get all the vitamin C you need from foods to help you prevent the common cold, you might need to supplement with this vitamin once you feel a cold coming on. A few studies have verified that while vitamin C might not prevent the cold from happening, it will help curb its severity and duration. Begin supplementing with 250 milligrams or more at the first signs of a cold. That’s only for adults; young children are much more susceptible to toxicity effects from vitamins and minerals, so keep their intake to within recommended levels or discuss higher doses with your physician.

Should I take vitamin C to prevent a cold?

Maybe. A large number of studies have shown that vitamin C does not prevent the common cold from happening, but it does help curb its severity and duration. If you don’t eat the optimal 9+ fruits and vegetables daily, then take a vitamin C supplement. The effective dose is about 500 milligrams to 2,000 milligrams daily starting at the first signs of a cold and taken in divided doses throughout the day. Discontinue after cold symptoms are gone. That’s only for adults; young children are much more susceptible to toxicity effects from vitamins and minerals, so keep their intake to within Daily Value levels or discuss higher doses with your physician.
