((HealthDayNews) -- Ever wonder whether you need vitamin supplements to stay healthy?
The Duke University Medical Center says you can get almost all the vitamins you need from a diet rich in fruits, vegetables and grains. However, if you don't eat well, vitamins are important -- especially if you also smoke or drink alcohol.
Women who are pregnant or thinking about getting pregnant should get at least 600 micrograms of folic acid every day. The medical center notes that taking smaller doses throughout the day can improve how much your body absorbs.
