Experts agree that the best way to get
the vitamins you need is through a
diet. Eating a variety of foods also
will give you the other nutrients you need to stay healthy.
Research does suggest that some people
may benefit from taking a multivitamin. These include:
- pregnant women and nursing mothers
- older adults
- frequent aspirin takers
- heavy drinkers
If you think you may need a supplement,
talk to your doctor. How much of a particular vitamin you need
depends on many factors. These include your age,
weight, activity level, family history,
general health, and stress level.
But beware of taking too much of any
vitamin. Megadoses of some, such as vitamins A, D, E, and K,
can be toxic.

some or all of the foods listed for each vitamin on a regular
basis. If you are, you're probably getting enough of that vitamin.
If not, you might consider adding some of those foods to your
