This is literally the all time best whole food vitamin that I have ever taken. It gives me more energy, mental clarity and brighter skin. Iridesca delivers a broad spectrum of vitamins and minerals and other nutrients that are bioavailable and processed in a way that all the enzymes are intact. This is far superior to taking synthetic vitamins, that have no co-factors, no enzymes and essentially no life in them. I have been taking Iridesca for almost two years and will continue to take this for the rest of my life.
