Tyrosine is a protein supplement that treats phenylketonuria, which is an inherited disorder. People suffering from phenylketonuria are unable to produce phenylalanine adequately, leading to a deficiency of tyrosine. Tyrosine Supplements help meet the needs of their bodies.

The supplements are known to treat many diseases like depression, attention deficit disorder, attention deficit hyperactivity disorder, narcolepsy, and insomnia. A lot of people take tyrosine vitamin for its skin benefits too.

How Tyrosine Benefits the Body?

Stress has a very negative impact on the body as it can affect reasoning, attention, knowledge, and memory by decreasing the neurotransmitters.

Mental Health

Tyrosine benefits us by balancing the mind in stressful situations.

A study conducted over 22 women, states that while performing a mentally challenging task tyrosine helped to improve memory when compared to the placebo group.

Cognitive flexibility refers to the ability to switch between performing tasks. The one to switch faster has greater cognitive flexibility. It has been that people with tyrosine deficiency are sleep deprived, and taking tyrosine food or supplements helped in achieving better sleep.

2. Use for Phenylketonuria

It is a rare genetic condition that is caused by a defect in the gene that creates the enzyme phenylalanine hydroxylase. The body uses the enzyme to convert phenylalanine into tyrosine(1) that produces neurotransmitters. However, the body is not capable of breaking phenylalanine without this enzyme and thus causes a buildup in the body.

One way of treating PKU is to limit phenylalanine through a proper diet. Using tyrosine supplements may also benefit, but more research needs to be done on this.

3. L Tyrosine for Depression


Tyrosine benefits human health by treating people with depression(2). Unbalanced neurotransmitters in the brain are the major cause of depression.
