Thread: About some substances

Hey

I need to make sure that I've got correct knowledge of this stuff, so if someone could tell me whether the following information is correct or not and if I'm missing something essential, that would be excellent. I'm interested in the effects on brain functions, not other body. So here we go:

Tea (especially green)
Contains antioxidants (catechins) that act as MAO-B and COMT inhibitors; contains L-Theanine

L-Theanine
Increases GABA and dopamine; influences serotonin levels in unknown ways

Rhodiola Rosea
Contains antioxidants that act as COMT and non-selective MAO inhibitors

Piperine
Enhances the bioavailibility of numerous substances (especially curcumin); has anti-depressive and cognition enhancing effects not well understood

Curcumin
Has anti-depressive and cognition enhancing effects not well understood; also acts as a non-selective MAO inhibitor

Olive leaf
Contains hydroxytyrosol that acts as a MAO-B inhibitor (+ other effects on dopamine?)

No need for in-depth analyses - just correcting of mistakes and so on. Thanks!

Frankly, Vieno
I am not sure what you are posting here for. This is what google is for. I did a quick look under hydroxytyrosol and all the answers popped up. This is a discussion forum, and is not really designed as a second google.
