Which nootropics are safe?
There is no easy answer to which nootropics are safe, as it can depend on a number of factors such as the individual's medical history, dosage, and potential interactions with other medications or supplements. Generally speaking, some of the most well-studied and commonly used nootropics that are considered relatively safe include caffeine, L-theanine, Bacopa monnieri, Rhodiola rosea, and creatine. However, it is always important to consult with a healthcare professional before starting any new supplement regimen to determine if it is safe and appropriate for your individual needs.
