Best L-Tyrosine

L-tyrosine – or tyrosine – is one of the 20 amino acids that form the building blocks of important proteins in the body – cells, muscle tissue, hormones, enzymes and more. It’s considered “non-essential” because it’s made in the body from the amino acid L-phenylalanine, provided you consume sufficient protein. (See Reference 1)

Extra tyrosine can be obtained in the diet from meat, eggs, dairy products, nuts, seeds, beans and legumes. Plus, tyrosine supplements are also available to boost your levels – either alone or as part of protein powder. (See Reference 2)

Tyrosine’s role in the body includes:

  • Forming neurotransmitters
  • Producing thyroid hormones
  • Regulating the stress response
  • Boosting focus and clarity
  • Improving motivation and mood
  • Supporting metabolism and energy

Let’s explore these health benefits in more detail.

L-Tyrosine Benefits

Cognitive Function

Tyrosine is helpful when you need extra brainpower, especially in the face of mental or physical stressors.

It’s an amino acid precursor to a compound called L-dopa, necessary for producing important brain chemicals or neurotransmitters such as dopamine, epinephrine and norepinephrine. These neurotransmitters play key roles in mood, motivation, memory, cognitive function and the stress response.

Studies conducted in 2013 and 2015 found that supplementing with L-tyrosine supports memory during mentally demanding tasks and improves cognitive flexibility – the ability to switch easily between tasks. (See Reference 4)

Another study looked at the effect of tyrosine during continuous nighttime work and acute sleep deprivation. The results found tyrosine helped subjects remain alert and reduced the decline in mental performance associated with sleep loss. (See Reference 5)

Thyroid Health and Metabolism

Tyrosine, in addition to minerals like selenium and iodine, is essential for the production of the thyroid hormone thyroxine.

Thyroxine is secreted by the thyroid gland – found in the throat – into the bloodstream, where it regulates many aspects of metabolism and energy production. Without sufficient tyrosine, you may experience fatigue, poor concentration, constipation, dry skin, weight gain, low mood and sensitivity to cold.

An interesting study on adults living in Antarctica found that a high-dose of tyrosine improved mood and increased levels of the thyroid hormone T3. It also significantly decreased thyroid-stimulating hormone (THS), suggesting a well-functioning thyroid gland. (See Reference 6)

Energy and Exercise Performance

Tyrosine’s role in supporting thyroid hormone production, healthy metabolism and optimal neurotransmitter levels make it a great supplement to boost energy and performance naturally.

A study on healthy men found that supplementing with a drink containing tyrosine – when taken an hour before cycling in the heat – resulted in greater endurance. (See Reference 3)

Mood

Supplementing with tyrosine is a great option for those struggling with low mood and lack of motivation – especially when triggered by chronic stress. Research has shown tyrosine can prevent the decline in mood associated with stressful situations. (See Reference 7)

It’s needed for the production of dopamine, the “feel-good” neurotransmitter linked to pleasure, reward and motivation. Unfortunately, stress depletes dopamine, causing an imbalance in the brain and contributing to poor mental health. (See Reference 8)

L-Tyrosine Considerations

L-tyrosine is generally safe when taken at the recommended dose. However, due to its impact on thyroid hormone levels, it’s not recommended for those on thyroid medication or anyone with a hyperactive thyroid gland.
