Rated 5 out of 5 by Must be dreaming...It helps! For those who's biological engine is in need of a little fine tuning...I'd say this is definitely worth trying. After marking off many other supplements due to symptomatic sensitivities or lack of benefits when I've tried them, L-Tyrosine seems to be providing me a notable difference. I'm glad I took stock in some of the other reviews in this case as the results have been positive. I've experienced some real increase in alertness & memory. I do find that I metabolize this rather quickly so some individuals might require taking dosage slightly less or more often. Please ALWAYS, safety first...Research & consult with a medical physician for any individual's needs & monitoring. Improved health = happiness! February 22, 2014
