    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.

    Question mark on this one for autoimmune thyroiditis

    Posted by iHerb Customer on Jan 11, 2018 | Verified Purchase

    January 2018: I thought I would give n-acetyl-tyrosine a go to address grey hair. There must be some contraindication as after taking it 4 days out of 7 for the last 2 weeks it's only given me bad fatigue - I get winded walking short distances or climbing up a pedestrian bridge. I've read that it may take the body time to adjust - I'm not willing to stay on this dose of 350mg as it's too strong. Will try halving the dose and report back.

    Thanks for your feedback!
