Are vitamins worth the money?

Do you pop vitamin pills daily to keep yourself healthy? If you do you're likely in the majority, because half of adults take vitamins daily. But are you taking the right ones and in the right amount?

If you don't know, you could be spending too much and possibly even causing your body harm. Vitamin sales have been growing at the pace of 4% annually and as more people lose health insurance, those numbers are expected to increase more rapidly. The Nutrition Business Journal expects sales to grow by 8% to a total of $9.2 billion annually as people turn to vitamins hoping they will stay healthy and avoid the doctor.
