Does L-Tyrosine Increase Dopamine?


The American Psychological Association states that over 58% of adults feel chronically stressed. This has led to a growing interest in supplements to improve wellness and mental health, specifically through boosting dopamine. However, finding reliable information on effective ingredients can be challenging.

L-tyrosine is one supplement gaining attention for its potential benefits in supporting mental health and increasing neurochemical production. This raises an important question: does L-tyrosine increase dopamine levels, thus offering a solution to stress and enhancing mental well-being?

This simple guide will cover everything you need to know about L-tyrosine: what it is, how it works, its potential benefits and side effects, and how to use it effectively. 

Key Takeaways

  • L-tyrosine is an amino acid essential for neurotransmitter production, as it aids in making proteins and other neurochemicals like dopamine, norepinephrine, and epinephrine.
  • A lack of this amino acid can result in problems such as phenylketonuria, affecting neurotransmitter and enzyme production.
  • L-tyrosine can influence mood, motivation, and focus, and help the body manage stress by contributing to neurotransmitter synthesis.
  • Since this amino acid is a precursor to dopamine, it is vital for cognitive functions and emotional well-being. Supplementation can be helpful to people with low dopamine production.
  • Some benefits of this supplementation include improved memory, stress management, mood regulation, and even support for metabolic issues through enhanced key neurotransmitter and hormone production.
  • Supplements that can support balance thanks to L-tyrosine and other adaptogenic ingredients like TUNE IN can support memory, focus, and other cognitive functions while helping with dopamine production.

What is L-Tyrosine?

Before diving into the debate, let’s first look at what L-tyrosine is and how it affects the “feel-good hormone” dopamine. 

L-tyrosine is a non-essential amino acid that helps build proteins and protein-related compounds. It can be found naturally in food and other animal sources, including eggs, meat, fish, nuts, oats, and dairy products.

The main function of this amino acid is to help the body’s production of neurotransmitters like epinephrine, norepinephrine, and dopamine, which all work specifically for the central nervous system and your brain.

While the body can synthesize this amino acid on its own, there are cases where your body might lack L-tyrosine. Since this amino acid helps with the production of proteins, other enzymes like thyroid hormones and skin pigment also rely on this to work.

That said, a deficiency of L-tyrosine can result in long-term problems, specifically chronic diagnoses like phenylketonuria. In this type of case, phenylalanine is not metabolized correctly, which restricts the production of enzymes.

L-Tyrosine Effects

We’ve talked about how L-tyrosine is an amino acid precursor to several neurotransmitters, but the effects of this amino acid are directly involved in the synthesis of dopamine, norepinephrine, and epinephrine, influencing, directly and indirectly, several body functions.

Now, let’s look at what it does exactly in your body.

Neurotransmitter Synthesis

L-tyrosine is directly involved in the synthesis of dopamine and other neurotransmitters, which play crucial roles in brain function, influencing mood, motivation, and focus

By serving as a “building block” for these chemicals, L-tyrosine can affect the brain’s neurochemical levels and, thus, various mental and emotional states.

Cognitive Function

This amino acid is known to influence cognitive processes, particularly under certain chronic stress or certain functions.

Because of that, the deficiency of this amino acid can affect mental performance, including memory, focus, and decision-making abilities, all by ensuring there are enough “building blocks” for the neurochemicals to work in our brain.

Stress Response

L-tyrosine has a special role in the production of two neurochemicals known for stress response: adrenaline and norepinephrine.

These two neurochemicals are vital for the body’s fight or flight response, affecting heart rate, blood pressure, and energy mobilization. 

By contributing to the synthesis of these compounds, this amino acid can influence how the body and mind respond to stressful situations and help our central nervous systems to keep in balance.

Mood Regulation

Due to its role in dopamine synthesis, L-tyrosine can affect mood and emotional well-being. Dopamine is not only important for pleasure and motivation but also happens to play a key role in mood regulation.

Because of this, fluctuations and balance in dopamine levels can potentially lead to better emotional states, thanks to L-tyrosine being available to create this chemical.

Does L-Tyrosine Increase Dopamine?

Think of L-tyrosine as the main ingredient for the proteins in our body. 

While our bodies produce this amino acid naturally, an L-tyrosine deficiency might occur if there’s constant stress in your life, bad absorption due to gastrointestinal problems, or a neurochemical imbalance.

Basically, the mechanism used to create dopamine will transfer tyrosine and then go through a process called hydroxylation. Without getting too scientific about the process, this amino acid is needed for dopamine production as it is key for the first step before creating the neurochemical.

If your body is deficient or low in this amino acid, it can alter the production of neurochemicals, including dopamine. 

This study on how tyrosine works in our body found that increasing the dosage of this amino acid may positively influence cognitive functions due to dopamine and other mechanisms in situation conditions as well.

Due to this, we can say that in people with deficiencies or with low dopamine production, L-tyrosine can support the production and help their brains reach balance.

L-Tyrosine Benefits

Since L-tyrosine is key for dopamine production, its effects and benefits of better intake can provide some potential benefits. 

Some of these, much like its effects, are either direct or indirect due to their role as primary ingredients for protein synthesis.

An increased dopamine production can potentially support memory and overall cognitive performance, as it is often attributed to help with working memory functions and according to this study, it can be critical for you to benefit from working-memory interventions and learning.

For stress management, L-tyrosine can help replenish neurotransmitter reserves that are often depleted with external and oxidative stress, including dopamine, epinephrine, and norephrine. 

Providing “raw materials” to create these chemicals can mitigate the effects of stress, like mood fluctuations, cognitive impairments, or even brain fog, helping your brain into a more balanced state.

Lastly, with a better hormone and neurotransmitter supply, there’s a potential to enhance mood and general emotional well-being. This steady neurotransmitter production can foster an environment that conducts a better mood, especially during stressful times.

Side Effects of L-Tyrosine

Now, while tyrosine supplements are generally considered safe, certain side effects can occur among some users. 

As with all supplements, it is important to always double-check with your healthcare provider if it is safe to consume L-tyrosine as part of your diet or if any medication you are currently taking might be affected by this amino acid.

Some typical side effects from this can include headaches, migraine, lethargy, and physical or mental fatigue. Other people might have problems affecting their digestive system, like acidity, heartburn, indigestion, and stomach malfunctioning.

Because of how it can also affect neurochemical production, some people with specific diagnoses like bipolar disorder might also be affected by this supplement as this condition has very specific conditions for neurochemical balance.

Having too much dopamine can also affect certain neurological conditions, which is why it is key to check with a healthcare professional before starting any supplement.

There is also limited study on long-term consumption of L-tyrosine, but there’s information that the consumption can result in some side effects. It is safe to take in doses of up to 150mg per kilogram daily for up to 3 months.
