Nootropics, also known as “smart drugs” or cognitive enhancers, are a class of drugs, supplements, or other substances that aim to improve cognitive function, such as memory, creativity, motivation, and attention. They are believed to work by altering the levels of certain neurotransmitters, such as dopamine, in the brain. Some popular nootropics include caffeine, piracetam, and modafinil. Nootropics can be of natural origin or synthetic. Some of the natural nootropics are herbs, vitamins, amino acids, minerals. However, it’s important to note that not all nootropics have been extensively studied, and the long-term effects of many of these substances are not yet known. Many nootropics are not regulated by the FDA and not all are legal. It’s important to consult with a healthcare professional before taking any nootropics, and keep in mind that they should not be considered a replacement for healthy lifestyle and diet practices.
