Assuming the data is good and there wasnt bias, the question becomes-Does this frequency between 8-13hz matter for performance?

Is having a 0.3mV2 difference in alpha waves significant?

Ive tried taking lTheanine and it doesnt seem to do much, even if I take many pills.

I've heard and read about the 10hz frequency inducing altered states of mind [0]. I've also heard anecdotally that both water and fire resonate/flicker at 10hz, which is why people focus and get lost in flame and water.

cursory research led me to believe that l-theanine on its own doesn't do much of anything. adding caffeine seems to be the ticket to the proposed improvements.

wonder if there's a way to package l-theanine and caffeine together into one supplement. maybe that's what those gas station "super focus!!1" pills use? i might give it a try this upcoming semester, i generally don't mind being a supplements guinea pig.

Not marketed crazily, but widely available, e.g. http://nootropicsdepot.com/caffeine-100mg-l-theanine-200mg-c...

It's called "tea".

There are plenty of caffeine+theanine supplements available. I take them in capsule form, available from Amazon from all sorts of brands. Beware though, some really overcharge for them.
