Product Overview


  • Neurotransmitter Support

  • 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.

Caution: For adults only. Consult physician if pregnant/nursing, taking medication, or have a medical condition. 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.

Handy for travel

Posted by 4914116887331997861 on Jan 12, 2015

I normally take L-Tyrosine in a powder for quick absorption, but opti for NOW Foods for travel. Good size, easy to swallow and it works. If it's your first time to this amino acid, be patient. Try 2 tablets in the morning and another 1 or 2 depending on how anxious you are feeling. Give it 1.5-2 weeks for a good indication. Now, I only take it if I know my day is going to be stressful, e.g. flight or big meeting. Ergo, not necessary to be on a daily dose if you are feeling OK.
