Tyrosine is a non-essential amino acid produced naturally by the body. It plays a crucial role as a precursor in the synthesis of several essential hormones such as norepinephrine and dopamine. Although our body is capable of synthesizing tyrosine, we may produce it insufficiently. This is why it is important to ensure that we meet our tyrosine needs through our diet and, where appropriate, adequate supplementation.

Tyrosine is found in many foods such as meat, poultry, fish, dairy products, eggs, leafy green vegetables, nuts and seeds. Adding these foods to our daily diet can help maintain adequate levels of tyrosine in our body.

Effects of Tyrosine

Tyrosine offers many beneficial effects for our physical and mental well-being:

• Helps combat stress: Tyrosine is the precursor of norepinephrine, a neurotransmitter involved in the stress response. By increasing norepinephrine levels, tyrosine can help reduce the negative effects of stress on our bodies and minds. It thus promotes a state of general well-being.
• Improves mood: Chronic stress can lead to a decrease in norepinephrine production, which can affect our mood and motivation. By providing an adequate amount of tyrosine, we can stimulate the production of norepinephrine and thus improve our emotional state.
• Reduces depressive symptoms: Tyrosine is also the precursor of dopamine, a neurotransmitter involved in mood regulation. Insufficient levels of dopamine can contribute to depression. By increasing the availability of tyrosine, we can promote the synthesis of dopamine and thus alleviate mild symptoms of depression.
• Improved working memory: Several studies have demonstrated that tyrosine supplementation can improve working memory, which is responsible for the active processing and manipulation of information in our minds. Particularly in stressful or mentally demanding situations, tyrosine can counteract mental decline and improve our cognitive abilities.
• Improves attention deficit symptoms: In some cases of attention deficit hyperactivity disorder (ADHD), there is an imbalance of neurotransmitters such as dopamine and norepinephrine. Tyrosine, as a precursor to these neurotransmitters, can help restore this balance and improve symptoms such as attention, distractibility and impulsivity.

Recommended dosages of tyrosine may vary based on individual needs and the advice of a healthcare professional. Generally, doses are between 500 mg and 2000 mg per day. It is important to note that tyrosine supplementation should be done with caution, following recommendations and monitoring the effects on our body.

In conclusion, tyrosine plays a vital role in our physical and mental health as a precursor to key hormones. By ensuring adequate intake of tyrosine through a balanced diet and, if necessary, controlled supplementation, we can support our overall well-being and improve certain disorders related to stress, mood, memory and attention.
