Works well for me, as a student with exams coming up. I usually get about 7 hours of solid "sit down with books" with these supplements. Be warned though, they can make you thirsty. I would have at least Two large cups of water. Also the PRofessional ones make you hungry too. You do get more done, but you might need extra food and water.
