I also prefer to take mono-vitamin groups rather than poly-vitamins, even though this creates quite a supply of packs in my cupboard, he he. However, even though I made this choice, I prefer to do extensive research and read about each natural supplement that I take. For instance, for Fulvic Ionic Minerals I also read an article and paid attention to all the details that were important. Starting from the containers they used and up to all other nutritional and health-related information.
