L-Tyrosine is a conditionally indispensable amino acid required for the production of the neurotransmitters dopamine, adrenaline, and noradrenaline, as well as for the skin pigment, melanin. Noradrenaline (norepinephrine) and adrenaline (epinephrine) are the main actors in the body's response to acute stress and, along with dopamine, help to support a positive mood and mental alertness. In addition, L-Tyrosine is especially critical for the normal function of the thyroid gland.

Suggested Use

Take 1/4 teaspoon in juice or water, preferably between meals, 1 to 3 times daily.

iHerb Customer Reviews

5 Stars to counter all moronic ratings

Posted by iHerb Customer on Oct 01, 2017 | Verified Purchase

Giving this product a 5/5 to counter the moronic individuals giving it a poor rating due to the powder not dissolving in water or tasting odd. This is a raw amino-acid powder, you rate it on the effects, not on how well it solidifies or tastes - it's not advertised as a gourmet dinner in a bottle.

Thanks for your feedback!

Great for chronic fatigue

Posted by iHerb Customer on Jan 26, 2017 | Verified Purchase

For some years I was low in energy and really struggling. Saw a new doctor who recommended 100% Tyrosine Powder. I started taking it and never looked back. My energy and stamina have returned. Everyone should be on this.
