Don't get any vitamins from Walmart! They mostly come from China and God knows what's in them.
Really, your daughter needs good, quality vitamins. This is not the place to be thrifty. If you want to save money, eat more rice and beans dinners, eat out less, cancel the cable or the dish. But don't give dangerous supplements to your little one!!
Even aside from the dangers, the forms of vitamins used by cheap manufacturers are in many cases useless, at best. For example, calciumj. Yes, it's technically calcium. But it's not a form that is useful to the human body. You might as well eat sea shells or sidewalk chalk.
Go to your local health food store and ask them what is th best choice.

PS and the best defense against colds is washing hands frequently, and taking mushroom complex and a probiotic (acidophilus, but look for a multi-dophilus complex). Also, very, very important to keep her sugar intake low. That includes juice! Sugar kills the immune system.
