Why DL-Phenylalanine over L-Tyrosine?

zorblart's Photo zorblart 18 Oct 2005

Hi all,

I am looking to incorporate a dopamine precursor into my stack, and wanted to know why i should choose DLPA over L-Tyrosine.

I am a student, and with L-Tyrosine being much cheaper and more available here in Australia - why shouldnt i choose it over DLPA - as DLPA is supposed to be broken down into it by the body anyway?

I remmeber something vaguely about tolerance to L-Tyrosine - is this true?


Cheers,
zorblart

I notice more from tyrosine than I do from DLPA.

Over fifty percent of DLPA is converted to tyrosine in the liver, however some people cannot convert it effectively. If I remember correctly, DLPA is also a precursor to PEA, while tyrosine is not. However the PEA will likely not be bioavailable unless you are taking a MAO-I aswell.
