Piracetam is most known for its ability to enhance cognitive function.
Piracetam won't make you more intelligent per se, but especially when combined with a choline supplement, it has the ability to improve your memory quite substantially. What piracetam does, in layman's terms, is increase the communication between the left and right part of your brain by increasing the blood flow between these two parts. Essentially, your logical thinking part of your mind will share more with the more imaginative part of your brain. This is why it increases memory in the brain. You can feel the fluidity of your thoughts increase, ideas seem to flow, if nootropics don't increase memory, I can certainly say they put your thoughts on a higher level.
Piracetam's effects are considered less strong compared to its more recent descendants but still remains a very popular choice for a well-rounded nootropic supplement. Many individuals use piracetam as a supplement to boost mental performance.
