Multivitamins are a combination of many different vitamins that are normally found in foods and other natural sources. These are used to provide vitamins that are not being sufficiently consumed in one’s diet. Multivitamins are also used to treat vitamin deficiencies caused by illness, pregnancy, poor nutrition, digestive disorders, and many other conditions.
For decades, doctors and health experts alike have suggested taking a daily multivitamin as a dietary supplement. In recent years though, more research calls to question whether or not these supplements, which can be very costly, are truly necessary.
