One Source Vitamins are cheap vitamins that are sold mainly at Wal-Mart but can be found online. There are, however, far better vitamins available within the same price range. Plus, if you’re looking to buy vitamins online, you’ll get a very limited selection from One Source. Here are some ingredients that I copied off of one of their vitamin labels; Corn Syrup, Sugar, Maltodextrin, Gelatin,Turmeric Color, Annatto Color. Those are all ingredients that shouldn’t be in a multivitamin. Depending on what you’re looking for, here is a post that has some of the best multivitamins available.
