Product Overview


  • Supports Brain Function
  • Dietary Supplement

N-Acetyl Tyrosine is an acetylated derivative of the amino acid L-tyrosine. Ordinary L-tyrosine is less stable and also less soluble in water, which may result in reduced bioavailability. Acetylation enhances the solubility and stability of certain amino acids.

N-Acetyl Tyrosine supports brain function by supporting the synthesis of the catecholamines norepinephrine and dopamine (neurotransmitters).

Suggested Use

Usage: Take 1 capsule 1 or 2 times per day, preferably with juice on an empty stomach or as directed by your qualified healthcare professional.

Other Ingredients

Cellulose, magnesium stearate (vegetable source) and silicon dioxide. Capsule consists of gelatin.

No wheat, no gluten, no soybeans, no dairy, no egg, no fish/shellfish, no peanuts/tree nuts.


Note: If you have a medical condition (especially bipolar, high blood pressure, or a history of malignant melanoma), are pregnant, lactating, trying to conceive, under the age of 18, or taking medications (especially MAO inhibitors), consult your qualified healthcare professional before using this product.

I bought this to take for my low adrenal and thyroid, and to help me sleep at night. It also helps several neurotransmitters work better, aiding dopamine and norepinephrine. One should always take amino acids with coenzyme B Complex or p-5-p B6, or it doesn't work nearly as well
