Green tea has caffeine also remember....also will stimulate...and to a higher extent when combined with tyrosine.
phenylalynine (PEA) is a precursor to tyrosine...it will make tyrosine in your body...of course you know that tyrosine converts to L-dopa then to dopamine then to norepinephrine (energy/irritability for some).
One way you can "balance out" the over-stimulation caused by tyrosine:
idealy tyrosine or stimulant based compounds should be taken in the morning or early day as they may effect sleep via this stimulation...ok...one reason they stimulate is because they produce norepinephrine. To counter this you could take a bit of 5htp or tryptophan at night....you need to work out a ratio here between tyrosine and 5htp....this is based on your own physiology and will require trial and error. The tryptophan or 5htp will produce seratonin and essentially "balance out" some of that stimulation.
Other than that...a benzo to rid excess stimulation or, if youre an anxiety patient, dont use tyrosine based supplements
> Thanks! It's interesting that I've been taking that supplement for five months now, and it's just this month that this has been happening. Plus, though Adrecor won't list exactly how much tyrosine is in the supplement (there's 450mg of a methionine, tyrosine, histamine, green tea and rhodiola blend) I can't imagine it being more than, say, 200mg at the most. Wild. Today I tried just taking half the capsule to see what's up. So far, it's similar but not as profound. I used to take something called Blast for years which had tons of phenalalynine (sp?) in it and never had that reaction, though it is similar to tyrosine (though I have taken tyrosine supplements before and had the irritability, big time!). One time, after having a 5-htp supplement the night before, a 500mg tab of tyrosine sent me into a mood plunge.
