I tried this a few years back. I actually bought the closely related amino acid DL-phenylalanine (sp?) (a dopamine/norepinephrine precursor), as I had heard that tyrosine can cause high blood pressure in susceptible people. (I'm hypertensive.) Your mileage may vary, but I had a strong 24-hour mood boost with just quarter of a GNC capsule--along with a "wired" feeling that wasn't entirely pleasant. (Rightly or wrongly, I now associate that feeling with elevated blood pressure, so it's been crossed off my list along with tyrosine...)
Bottom line--I'd be cautious with dosage until you know how your system's reacting to it. I'd be especially prudent if you're taking any other meds that act on norepinephrine. (And of course, don't even think of it if you're taking an MAOI!)
best,
jd> Well tonight I went to my local GNC and bought a couple of bottles of the amino acid L-Tyrosine. The bottle contains 1000mg. tablets. I was wondering if anyone here had any experience with this. I am a little curious about dosing and amount. I am taking it to improve my concentration and to relieve some minor fatigue I experience in the mornings upon awakening. Any and all anecdotes are appreciated thanks.
