Tyrosine is an amino acid that supports brain function and mood. It helps produce neurotransmitters such as dopamine, which affect mood, focus, and mental alertness. Found in foods like cheese, soy products, fish, and poultry, tyrosine is important for emotional well-being, stress response, and thyroid function.

Testing for tyrosine levels could be beneficial for individuals experiencing symptoms of low dopamine, such as depression, lack of motivation, or cognitive difficulties. It’s also useful for people with phenylketonuria (PKU), a metabolic disorder affecting tyrosine levels. Individuals under chronic stress or those with thyroid disorders, as tyrosine is a precursor to thyroid hormones, might also find testing helpful.
Tyrosine is found in protein-rich foods like chicken, turkey, fish, and beef. Dairy products and eggs also contain good amounts of tyrosine. For plant-based diets, soy products, nuts, seeds, and whole grains are rich in tyrosine. Legumes, especially beans and lentils, also provide this amino acid.
Tyrosine supplementation can support cognitive function, enhance focus, and improve mood, particularly under stress or in those with dopamine-related mood disorders. It can also aid in thyroid function and may help manage symptoms of phenylketonuria (PKU) when used under supervision.
