While nootropics may offer a range of benefits, there are also potential risks and concerns associated with their use. Some synthetic nootropics have not been thoroughly studied, and their long-term effects on the brain and body are largely unknown.
Additionally, there is a risk of addiction with some types of nootropics, particularly those that stimulate the brain. It is also possible for nootropics to interact with other medications or medical conditions, so it is important to consult with a healthcare professional before starting a new regimen.
