Cell Diagram
Tyrosine is a type of amino acid, which are the building blocks of protein. The body makes tyrosine from another amino acid called phenylalanine.
In the diet, tyrosine can be eaten in dairy products, meats, fish, eggs, nuts, beans, oats, and wheat. 

The body uses tyrosine to make chemical messengers that are involved in conditions affecting the brain, such as mental alertness.


The main benefits of L-tyrosine are related to its ability to replenish catecholamine levels in the brain, which can become depleted under stressful conditions.

Tyrosine also helps the body produce several important substance including dopamine, adrenaline, thyroid hormones and melanin.


Tyrosine is vital for good health, and its absence can mean that the body does not make enough neurotransmitters to support attention, cognition, and mood.

People with the genetic disorder phenylketonuria (PKU) have a high risk of tyrosine deficiency because the body does not convert phenylalanine to tyrosine.

L-Tyrosine: Stress management and clarity

L-tyrosine is a naturally occurring amino acid crucial for producing various neurotransmitters in the brain, including dopamine, adrenaline, and noradrenaline. Found in many high-protein foods like turkey, chicken, dairy, and certain seeds, L-tyrosine plays a pivotal role in supporting cognitive function, mood regulation, and stress management. As a supplement, it may potentially enhance mental performance during stressful situations by supporting the production of neurotransmitters, thereby improving focus, alertness, and cognitive flexibility. 

Some research suggests that L-tyrosine supplementation may aid people who may be particularly at risk of stress-induced cognitive decline, such as military personnel, athletes, or those with demanding cognitive tasks, by potentially mitigating the impact of stress on cognitive performance.
