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.

Other Ingredients

Cellulose (capsule), rice flour, stearic acid (vegetable source) and silica.

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.

This extra strength product has more L-Tyrosine (750 mg per capsule) than our regular strength product (500 mg per capsule).

Good, I think?

I’m not sure about this product. In the beginning I really felt like it helped but after a week or two I feel like I’m back to scratch. I take 2-3 pills a day but not certain it works.

Thanks for your feedback!

Missleading product. Highly unethical

Posted by iHerb Customer on March 7 2018 | Verified Purchase

I have contacted NOW about this product and was very surprised when I was told this is not a vegan or even vegetarian product. In fact 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 an animal and on top of this it is also not okay to mislead customers by advertising this as a Veg Capsule.

Thanks for your feedback!
