Vitamin C or Ascorbic Acid is one of the most well known supplements. Most mothers and pediatricians used this vitamin as way to prevent common colds in their newborns and children.

However, new studies have shown that Vitamin C does little to prevent or shorten the length of colds.

The new study, appearing in Wednesday's Journal of the American Medical Association, said it's still too early to rule out health benefits of vitamin pills adding that antioxidants are more effective when they are consumed in food rather than pills
