L-Tyrosine is a supplement that promotes improved motivation, stress relief, reduced symptoms of depression and enhanced concentration and energy.
What is Tyrosine?
Tyrosine is one of many standard amino acids that are used by the cells in our body to build proteins and the production of brain chemicals that effect cognition.
In the case of Tyrosine, it is associated with producing dopamine, norepinephrine and epinephrine. These brain chemicals or neurotransmitters are associated with moods and reactions to stress.
Our body already produces it through food consumption but it may be a consideration to supplement it for its potential benefits in certain situations.
Tyrosine is thought to be made from phenylalanine, an amino acid that the body does not produce and is found in food sources.
We have to get it from foods that are high proteins, including, eggs, chicken, turkey, cheese, milk, fish, beef, soy products and yogurt. Oddly enough, a high concentration is found in aspartame.
Its name comes from the greek word “tyros” which means cheese because it was originally discovered from a protein found in cheese.
Tyrosine is created from phenylalanine, another amino acid that is associated with pain relief and anti-depressant agents.
This supplement is thought to cross over the blood-brain barrier and reach the brain quickly. It is than thought to increase the release of certain neurotransmitters or chemicals in the brain that help the cells to communicate better by sending signals between the neurons.
Important neurotransmitters including epinephrine, dopamine and norepinephrine. These are all brain chemicals associated with our alertness, focus, attention and mood.
It is thought that when we are under stress, catecholamines (hormones) are released at a faster speed as a fight or flight response and may result in the depletion L-Tyrosine in the brain. High stress may effect our cognitive functions. However, more research needs to be done.
Tyrosine also produces Melanin. This is a pigment that is responsible for our eyes, hair and skin color and is thought to protect the skin from UVB radiation that may lead to cancer.
Also, it helps to regulate the functioning of organs and hormones including thyroid, adrenal and pituitary glands. Tyrosine is part of the structure of almost every protein in the body.
When taking a Tyrosine supplement in any form, it is able to enter the central nervous system quickly.
Benefits of Tyrosine
The key benefit of this supplement is that it may help to reduce stress levels. More specifically, it may prevent cognitive decline that is due to stress.
This is directly related to the potential increase of these stress hormones including norepinephrine and epinephrine which prepare the body to handle stress.
This supplement is not only used to potentially reduce stress but research suggests that it does improve mental performance and memory function while under stress. This includes cold induced stress, noise and multitasking although more research is needed.
Also, Tyrosine is also thought to be a preventative of depression, enhancing libido and raising motivation. This may be due to production of Dopamine which is responsible for our mood and is the pleasure center of our brain.
When neurotransmitters including Norepinephrine and Epinephrine are elevated, it may also act as an appetite suppressant and reduce stored fat.
Tyrosine Side Effects
This supplement is considered generally safe and is well tolerated. However there are a few potential side effects and interactions that need to be addressed. Some side effects may include;
