Tyrosine (Pot of 90 capsules)

Share this product


Tyrosine is a significant amino acid that plays a role in:

  • The synthesis of thyroid hormones T3 and T4. These are important for growth and metabolism.

  • The synthesis of catecholamines, for which it is a crucial starting ingredient. Catecholamines are hormones and neurotransmitters, and include dopamine, adrenaline (also known as epinephrine) and noradrenaline (or norepinephrine ). They are released as a stress response, part of the fight-or-flight reaction, and help transfer signals between cells in the brain.

  • The synthesis of melanin, which colours the skin, hair and eyes.

    Suggested dose: one capsule per day.

    Because of tyrosines role in the creation of thyroid hormones, it should not be taken at the same time as thyroid medication unless under direct advice from a qualified healthcare professional.

    Advice should also be sought before taking tyrosine if you have high blood pressure or are taking monoamine oxidase inhibitors (MAOIs).

    An excess of tyrosine might cause skin, eye or brain problems. Tyrosine might trigger headaches in migraine sufferers.
