A well-balanced diet should provide all the vitamins a body needs, but some people
opt to take supplements. There are times, such as if you're pregnant or nursing, when
no matter how well you're eating, it may be beneficial to take vitamins. Habits like smoking,
doing drugs, and drinking alcohol or a lot of caffeinated beverages (coffee, tea, or colas)
deplete the body's store of certain vitamins.
