I haven't tried L-Theanine yet although I remember that mrsD recommended it to me years ago. There's only so much money to go around on supplements. They're very expensive here where I live and so I usually buy them from the US.

There have been many other posts about L-Theanine on the forum/s.

PhamaGABA is another anti anxiety supplement.

Everyone is different. What works for one might not help someone else.
I see that even in my own family.
