Product Overview

L-Tyrosine is a free-form amino acid which rapidly crosses the blood-brain barrier. It is a precursor for the neurotransmitters dopamine, norepinephrine, and epinephrine, for thyroid hormones, and for enkephalins, special peptides which subdue messages of physical discomfort. L-Tyrosine is also a precursor for the protective skin pigment melanin.

Good stuff, but...

Posted by iHerb Customer on February 26 2017 | Verified Purchase

...you really have to understand yourself (to know that this stuff might help). First few days were really weird, my body had a tingly feeling all over. I'm taking 1 pill a day, sometimes 2 and it keeps my emotions quite stable. I'm happier and I don't worry about stupid stuff anymore. Oh and it might keep you really awake the first week or two.

Thanks for your feedback!

More energy

Give me motivation to do stuff, but if taken to many, drive my nerves on, and i get angry very quickly.

Thanks for your feedback!
