I have a health condition that causes me to be continually fatigued and often have difficulty concentrating, for this reason Sharp Mind is not the first product like this I have tried. While the ingredients are similar to other formulations there is something about this product that just doesn't sit right. Most of the time it just gives me a headache. I've also found it to be more expensive than other products which have worked better for me. But, everyone is different, it might work for you.
