> 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...)

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.

I really do not believe it will help with your concentration. A safer alternative may be Gingko biloba for concentration. These products only work if your concentration is already compromised (eg. as in Alzheimer's). If you are trying to boost brain power, the only way to do it is to exercise your brain more. Good luck - Cam W.
