Its good to take multivitamin everday ?

Depends on which one: Yes, it's good to take a multivitamin every day provided that you choose a good quality multivitamin. Some recent studies purported to find that multivitamins are not beneficial but these studies used poor-quality vitamins like centrum. Many studies that use better quality vitamins find significant benefits. See http://bit.Ly/18xyule for independent ratings of 101 multis see http://bit.Ly/1b36cq0.

Not really: If you have a specific proven vitamin deficiency, then take that vitamin. But multivitamins are not helpful, and can be dangerous despite the vitamin industry propaganda. The discussion about "good" or "bad" multivitamins is foolish. Save your money and buy a gym membership. Between multivitamins and exercise, only exercise has a proven medical benefit.
