This product is fantastic in terms of keeping my head clear. I know it is primarily touted for weight loss, and it works in that I am not eating all the time! It has a clarifying and focusing effect on my mind. If you've ever had the foggy feeling from a head cold, then you know what I mean when I say that this supplement clears that feeling up. Too much coffee gives me the jitters and makes my heart race. One of these capsules clears my head and "wakes" me up without the side effects of too much coffee. Better still, it doesn't interact with the multitude of medications I am taking! I love it and the price at Well.ca is the best I have found anywhere.
