Are you a vitamin taker? If so, do you know why? Seriously, the isolated minerals and vitamins some people are used to taking don't perform at their best unless working with other vitamins and minerals in synergistic fashion.

Enter the multivitamin. These supervitamins generally have a decent dose of many vitamins and minerals that are given to the body at the same time. Result: enhanced effectiveness.

Ask your doctor at your next visit which multivitamin he or she would suggest for you, and why. Kids and women are more in need (in general) of multivitamins. That is, unless you live an incredibly healthy lifestyle with nothing but natural foods and water as your only beverage.
