There are a few key differences between nootropics and adaptogens, and the main one is in what each of them intends to accomplish. A nootropic seeks to boost brain function like memory, cognition, concentration, alertness, creativity, and attention. On the other hand, adaptogens are designed to help us deal with stressors.
While nootropics may indirectly help us deal with stress and anxiety, they will only do so because we will perform better and wonāt have to deal with external factors related to poor performance. On the other hand, an adaptogen will tackle the stress and anxiety that we feel directly.
Another thing to consider is the way that nootropics and adaptogens work on a biological level. Adaptogens interact with the HPA, but nootropics have a wide range of different mechanisms that they work through. This is due to the sheer variety of nootropics that are available compared to adaptogens.
