Frequently Asked Questions About Tyrosine Supplements

What is Tyrosine?

As an amino acid, tyrosine is the building block of proteins. (1) You eat tyrosine in high-protein foods such as chicken, turkey, fish, and milk. The name of this amino acid is derived from the Greek word “tyros” which means “cheese.”

The amino acid was initially discovered in casein, the main protein present in milk and cheese. The discovery was made by German chemist J. von Liebig in 1846. (2)

Though it is present in foods, tyrosine can also be manufactured by the human body. Because of this, it is considered a non-essential amino acid. The body uses tyrosine to produce noradrenaline and dopamine, which are neurotransmitters important to regulating mood and behavior. (3)

Tyrosine’s role in the production of these critical neurotransmitters has made it the subject of research on cognitive and mental health benefits. There have been a few studies on supplemental tyrosine’s effects on cognition, stress, working memory, and even blood pressure. (3)

The supplement also has been used for the treatment of a rare birth defect called Phenylketonuria (PKU), which causes an amino acid called phenylalanine to build up in the body because the person cannot process it. Phenylalanine is used by the body to make tyrosine, so people who can’t process it are at risk for low tyrosine levels.  (1)

Overall, tyrosine supplements may benefit a number of needs and conditions, but more research is necessary.

What Are the Uses & Benefits of Tyrosine?

Tyrosine supplements have been used for mostly mood and cognitive benefits. These uses include:

  • Memory: Tyrosine supplements have been studied for effects on a form of short-term memory called working memory. This form of memory is the brain’s system for storing and managing information temporarily to complete complex cognitive tasks such as learning, reasoning, and comprehension. (4) One study has examined the effects of tyrosine supplements on cold-induced working memory deficits, which is to say humans were subjected to cold temperatures and given matching accuracy tests. The study found that tyrosine supplements helped preserve working memory, but there were only 8 human subjects involved in the study. (5)
  • Cognition: A number of studies have shown tyrosine to have a preserving effect on cognitive functions during times of physical stress. A study conducted on military cadets found tyrosine beneficial for improving mood and cognitive function during combat training. (6) Another study with military personnel showed that tyrosine supplements may reduce the effects of environmental stressors, such as cold and reduced oxygen, on mood and cognitive function. (environment) Finally, a study showed that tyrosine supplements may improve cognition for those under conditions of sleep deprivation. (7) All of these studies show promising tyrosine benefits, but they are also all short-term studied conducted on only young adults for a short period of time. More research is necessary.
  • Phenylketonuria (PKU): Those born with a rare condition known as Phenylketonuria (PKU) are less able to produce tyrosine in their own bodies, so tyrosine supplements have been used to offset potential deficits.  (1) This is because their bodies have trouble processing a tyrosine precursor known as phenylalanine, and found in many tyrosine-rich foods. Those with PKU have to restrict the amount of phenylalanine they consume, which reduces the amount of tyrosine both consumed and produced. (8) Research has shown that good tyrosine supplements can increase the levels of tyrosine in those with PKU without raising phenylalanine levels. (9, 10)

How Do I Take Tyrosine?

Tyrosine supplements are often taken approximately 30-60 minutes before any acute stressor at dosages of 500-2000mg. Studies use tyrosine dosages of 100-150mg 60 minutes before acute stressors, such as exercise. (3)

Are There Any Side Effects and Precautions?

High doses of tyrosine may cause digestive issues, which can be mitigated by splitting the dosage in half-hour increments. Some other side effects may include nausea, headache, fatigue, and heartburn.

How Do I Pick a Good Tyrosine Supplement?

Good tyrosine supplements are made with L-tyrosine rather than N-acetyl L-tyrosine (NALT). L-tyrosine is also known as free-form tyrosine and is better absorbed than NALT. (11) Every product on our top ten tyrosine supplement list uses L-tyrosine.
