Nootropics, also known as smart drugs, memory enhancers, and cognition enhancers can increase memory, motivation, attention, and focus. You must note that although nootropics may increase performance, they will not give you superhuman mental capabilities such as those in the movie Limitless when given NZT-48. L-Theanine and caffeine are two of the most commonly used nootropics for beginners, with creatine, B-complex and bacopa monnieri coming in next. You must understand that this video is informative and you should contact your professional physician before trying any of these. With that said, many of these smart drugs can be found on Amazon. Beware that there are many side effects that come when trying a new drug or medicine, so make sure to do your research and read lots of personal stories. Also understand that great exercise and sleep can do way more than any of these pills or supplements. Adderal, amphetamines, and racetrams fall under the nootropic category, but should be used under professional supervision with the opinion of a licensed doctor.
