I've tried Mannatech, Advocare, you name it, but when I went on intraMAX, wow! What a difference in such a short amount of time. My allergies cleared up, I didn't get that summer time cold, even my complexion is getting better. I have energy that wasn't there before. I love the peach-mango flavor. I give it to my kids, too. I've noticed they seem to be "focused" and more attentive. I'm telling everyone about intraMAX.
