I have only been taking the product for a short amount of time, but I can say for certain that it has helped me tremendously in coping with the extreme stress that the last few months have brought me. When I am stressed I have an extreme cortisol response which causes exhaustion and accumulated belly fat. Since I've been taking the product none of those things have happened and the stress I've been under has been worse then times in the past when I have had those responses. I give it a 10 out of 10 for clear thinking, energy, good sleep filled nights, reduced cortisol response in times of stress, healthy food cravings, and balanced mood.
