Product Overview


  • Neurotransmitter Support
  • Pharmaceutical Grade
  • Healthy Glandular Function

  • GMP Quality Assured
  • A Dietary Supplement

The L-Tyrosine used in this product is Pharmaceutical Grade.

L-Tyrosine is a non-essential amino acid that plays an important role in the production of the neurotransmitters dopamine and norepinephrine. In addition, because L-Tyrosine is necessary for the synthesis of thyroid hormone and epinephrine (adrenaline), L-Tyrosine supports healthy glandular function and stress response.

Suggested Use

As a dietary supplement, take 1 capsule 1 to 3 times daily, preferably between meals. Consider taking these other NOW products: L-Phenylalanine and Acetyl-L-Carnitnine

Other Ingredients

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

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) that our regular strength product (500 mg per capsule).


Store in a cool, dry place after opening.

Person with thyroid disease (hyperthyroidism), melanoma, or those taking MAO inhibitors or other mood altering medications should seek the advice of a physician before consuming this product. Keep out of reach of children.

Mood enhancer

Posted by iHerb Customer on Jun 06, 2017 | Verified Purchase

I have tested l-tyrosine before. It has mood stabilizing effects on me. Maybe thanks to the better dopamine release I do also have better motivation.

Thanks for your feedback!

Wsparcie dla tarczycy

Posted by 5439779701896279184 on Mar 30, 2017 | Verified Purchase

Po wizycie u endokrynologa okazało się, że tak naprawdę w przypadku moich problemów z tarczycą lekarz nie widzi problemu (pomimo podwyższonego TSH) . Uważał też, że moje subiektywne samopoczucie nie ma znaczenia. Co pomyślałam o lekarzu to moje, ale wzięłam sprawę w swoje ręce. Zaczęłam stosować L-tyrozynę oraz atomidynę (jod). Takie połączenie pozwala organizmowi na wytwarzanie tyroksyny (hormon tarczycy) i u mnie to się sprawdza. Moje samopoczucie obecnie jest świetne. Po dawnych kłopotach nie ma śladu. U mnie L-tyrozyna sprawdza się bardzo dobrze.

Thanks for your feedback!
