It shouldn't do. Multivitamins taken in recommended doses have no commonly reported side effects.
I always get charley horses in my legs and feet when I take multivitamins. I even tried a powder multivitamin that I added to a beverage hoping I could take that without having the muscle cramping but even that caused the charley horses. It hasn't always been this way for me and I wish I knew what the problem was so that I could return to taking a multivitamin.
