L-Tyrosine is a non-essential amino acid that plays an important role in the production of neurotransmitters dopamine and norepinephrine. In addition, because L-Tyrosine is necessary for the synthesis of thyroid hormone and epinephrine (adrenaline), L-Tyrosine supports healthy glandular function and stress response.

Rated 4.8 out of 5 by 9 reviewers.
Rated 5 out of 5 by Stops appetite Stops appetite Take between meals, only works on people who do not eat gluten May 30, 2015
Rated 5 out of 5 by amino acid I was surprised that an MD suggested using the amino acid Tyrosine to build up the level of protein needed for health. So I ordered a supply and it has enhanced my health. My preference for capsules was also a reason why I choose this item as well as the reasonable cost. November 17, 2013
Rated 5 out of 5 by Noticed a Difference Right Away I noticed an improvement in almost everything about me withing a couple days. I had heard that this product affected dopamine and I can honestly say I'm positive it has triggered it or something. I'm also shocked in how quickly I noticed a difference. This is the first time of trying this supplement, but I can say, without question, I will not let it run out. June 7, 2013
Rated 5 out of 5 by Wonderful Product Love it! Not sure the whole scoop on what it's doing, but I sure feel good! March 2, 2013
Rated 5 out of 5 by Definite difference Stress levels are DOWN for sure. I had forgotten that I was taking these yet had been noticing that I was feeling far more calm, even when circumstances were not improving. I went into my cabinet to refill my vitamin caddy and remembered this little number! I hope it works for others as well as it is working for me! April 27, 2012
Rated 5 out of 5 by Good It works very well with Folic Acid. I've lost weight since I've been taking it. I take it before bed because it helps me sleep. April 12, 2012
Rated 4 out of 5 by Will buy again. I take tyrosine to assist my adrenal glands, and I do feel it works for that purpose. It's a great amino acid supplement for natural energy. I take one every morning, so this bottle lasts a long time. July 29, 2009
