Is Kratom a Nootropic?

I’ve been taking kratom for years for energy and mood, but I realized that it’s also supposed to increase mental clarity, alertness, creativity, motivation, etc. IO definitely get a lot done during the day when I take it.

I didn’t even know what nootropics were before I joined this sub (but knew of the common ones). It seems like Kratom fits the definition? Just curious either way since I’ll continue taking it for energy and sleep.
