L-Tyrosine is an important amino acid that plays a key role in the synthesis of several key hormones and modulators of nerve function. The body makes L-tyrosine under normal physiological conditions. It can also be found in plant and animal proteins such as dairy products, eggs, fish, beans, and oats.
Some of the key benefits and actions of L-tyrosine include:
Thyroid Support: In the thyroid gland, L-Tyrosine is taken up and used with iodine to synthesize the thyroid hormones T3 and T4 (thyroxine). This is especially important because the biologically active thyroid hormone, T3, is the body’s primary hormonal regulator of metabolism and is important for normal growth and development.
Catecholamine precursor: Tyrosine acts a building block for several brain-stimulating catecholamines (dopamine, noradrenaline, and adrenaline) which support stress response mechanisms and the ability to concentrate.
