Nootropics, also known as cognitive enhancers or smart drugs, are substances that are believed to improve cognitive functions such as memory, focus, creativity, and motivation. The exact mechanism by which they work is not fully understood, and it likely varies depending on the specific nootropic.
Some nootropics are thought to work by increasing blood flow and oxygen to the brain, while others may enhance the functioning of neurotransmitters such as acetylcholine, dopamine, or serotonin. Some may also increase the production of certain proteins and enzymes in the brain that are involved in learning and memory.
It's important to note that the effectiveness of nootropics can vary depending on the individual and the specific nootropic being used. It's also important to follow dosage instructions carefully and speak with a healthcare professional before starting any new supplement regimen.
