- Amino Acid Supplement
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, as well as for thyroid hormones and enkephalins, special peptides which subdue messages of physical discomfort. Tyrosine is also a constituent of amino sugars (glycosaminoglycans), special compounds which have important roles throughout the body.
1/4 teaspoon daily between meals.

iHerb Customer Reviews
I use this because it seems to help stabilize my moods. I Used to take Wellbutrin for depression, and it worked well, but when I lost my insurance I had to find a lower cost alternative that would boost some of the same neurotransmitters as Wellbutrin did. This amino acid was recommended to me. It doesn't replace the effects of the Wellbutrin for me, but it does a good job. I use 1/4 teaspoon with breakfast, and sometimes with lunch as well. I like the freeform powder because it allows custom dosages, and is cheaper and absorbs very fast. This amino acid may keep you up at night, so don't take it before bed. Good luck.
The cost of powder (non encapsulated) amino acids is decidedly less than the other forms. L-Tyrosine is tasteless, and, therefore, I find it very palatable and easy to take. A good deal for a high quality product.
Not for everyone, I guess.

This didn't appear to agree with me. Even one small dose made me feel bad; maybe it was just a socalled "discharge of toxicity" or something, but some of us need medicines that don't produce such profound discomfort. But I would invite others to try it.

Tasteless, odourless. Somehow it seems to make me less tired.

Makes me feel great. Concentration at work, cravings are gone and feel happier in general. It's an amazing product and not expensive.
