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 capsule 1 to 3 times daily, preferably between meals.

Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients. Produced in a GMP facility that processes other ingredients containing these allergens.

Feels clear in My head

Feels clear in My head and light, Best Regards from Denmark

Thanks for your feedback!

Highly unethical product

Posted by iHerb Customer on March 7 2018 | Verified Purchase

I have contacted NOW about this product and was surprised it comes from feathers. I have seen plenty of undercover footage about the feather industry, and would like to encourage everyone to do some research and find a plant based Tyrosine. There is absolutely no reason to abuse animals. Plenty of alternatives available.

Thanks for your feedback!
