In reply to Larry-do you know of any evidence on L-Theanine..., posted by btnd on October 11, 2003, at 5:48:57
> Hi,
> Do you know of any evidence on L-Theanine increasing GABA brain levels? Or does it interact with GABA(A)/GABA(B) receptors? I couldn't find any studies on pubmed regarding theanine+gaba, although many websites claim that theanine increases both dopamine and gaba levels (the dopamine increase however is well documented, and the glutamate NDMA antagonism effect too). I'd appreciate if you have any sources on this aspect.

What is interesting in that theanine is a caffeine antagonist. I didn't know that. I love questions. Got any more? ;-)
