i know several of these posts say somethign about a product called LThymaine or something like that i got some saturday night and i took onw sunday morning and felt like crap all day i think it even bothered my stomach. what is anyone's input on this subject? i might have spelled it wrong.

Pennie,

L-Theanine is merely an amino-acid. It's derived from green tea. It doesn't make you **feel** anything other than normal but less anxiety. If you felt crappy, then you already felt crappy.

I am not sure what type of product you purchased or what is in it, but I suppose that would all depend.

You need to take 10mg of B6 in order to metabolize ANY amino acid.

Here is what the Physician's Desk Reference says about L-Theanine: http://www.pdrhealth.com/drug_info/nmdrugprofiles/nutsupdrugs/lth_0296.shtml .
More studies need to be conducted to determine safety and efficacy.

I hope this answers your question.
