I see a lot of people say "I take theanine" but what do you mean exactly? You just drink tea or does it come in other forms?

[singhrac]

L-theanine is readily available in supplement form in the US (e.g. $6 for a bottle of 100 pills). I don't take it regularly but that's mostly because I haven't examined the evidence carefully.

Probably supplements. Be careful about what you buy though, internet is full of random "made in china" supplements containing god knows what

[meowkit]

It comes in natural things like mushrooms / green tea, but its also synthesized in capsules / powder / products like neurogum.
