Review: Happy mistake - I purchased on accident, intending to buy the 2mg magtein version. After reading the label I thought I'd keep it and try it out. Well I'm glad I did because it's now something I keep on hand. enXtra is the real deal. The best I can describe it is like a more delicate version of caffeine. It will help you keep your focus to help you accomplish your tasks without a buzz or crash at the end. Recently I used it on a 14 hour drive and I kept alert the whole time. I had coffee in the morning and MagMind in the afternoon. It lasted me until I got to my destination. So any time I find myself lacking in focus or attention, I take this and it works wonders for me.
