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

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.

На намалена функция на щитовидна жлеза

Posted by rionabg on Jan 15, 2018 | Verified Purchase

От 22 години имам намалена функция на щитовидна жлеза. Бяха ми изписали L-tiroksin и съм го пила дълги години. Сега съм го заменила с L-Tyrosin -по една капсула сутрин на гладно ,като взимам допълнително и селен и по една чаена лъжичка домашно приготвен сироп от мед и зелени орехчета. Чувствам се добре - много по добре от времето когато пиех Л-тироксин.

Thanks for your feedback!

I suffer from low dopamine levels and this has given me back a lot more energy and alleviated me from the dark clouds hovering over my head.
