The main purpose that multivitamins serve is to act as a dietary supplement for human beings. It is an easy and effective replacement for dietary minerals, vitamins and nutritional elements. Most of the multivitamins are available in the form of powders, liquids that can be injected, capsules, tablets, pastilles etc. Most of the time a multivitamin capsule is recommended along with minerals. However a multivitamin is something which includes vitamins that can be three or more. The multivitamins technically do not include drugs, hormones or herbs in their composition.
There are various benefits of taking multivitamins. One needs to however take the medicine only under the prescription of a physician. One can replace his or her diet with vitamins or multivitamins depending on the nutritional needs of the person taking the medicine. Mostly people who suffer from dietary imbalances need to take multivitamins as dietary supplement as prescribed by the physician.
In general, children's multivitamins needs are far different when compared with that of adults and children may not have to depend on multivitamins as dietary supplements like adults do. According to the American Academy of Pediatrics, 'a diet based on the Food Guide Pyramid provides adequate amounts of all the vitamins' a child needs.
However there are certain precautions that one needs to take while taking multivitamins. Especially if some one has certain medical condition, one needs to be extra cautious. If a women is pregnant she should consult a doctor prior taking the multivitamin tablets or capsules. However one should not take multivitamins in an excess. Because it might be risky for an individual with any sort of medical condition in particular. Again a pregnant woman should be cautious about taking vitamins because an excess of vitamin A might result in birth defects of the unborn child. Again an excess intake of vitamin A or vitamin E might result in shortening life span instead of increasing it.
