Although widely believed to significantly affect the course of the common cold, studies of Vitamin C have shown inconsistent results. Some research suggests that Vitamin C does nothing to shorten the duration of the common cold, whereas other studies suggest it may play a small role in prevention. The verdict is still out.
Another uncertain supplement is Vitamin E. At this time, studies show very mixed results. But unlike Vitamin C, too much Vitamin E may actually be harmful, so take it cautiously. Another widely used product believed to help prevent the common cold is Echinacea. Unfortunately, there is little data to suggest that it does much of anything for prevention.
So if you want to build your immune system, stick to the tried and true methods. Maintain a well-balanced diet, exercise regularly, and try to get at least eight hours of sleep each night. Taking a standard daily multivitamin may help also help to support the immune system.
