Tyrosine is a non-essential / replaceable / amino acid that is part of the proteins in the human body.
Normally, the body can synthesize enough tyrosine by converting another amino acid, phenylalanine. Tyrosine is always present - in supplements, food, even in some drinks.
In certain diseases such as phenylketonuria, the synthesis of tyrosine it is not possible and it passes into the groups of essential (essential) acids and must be taken in the form of supplements or from food sources.
Tyrosine maintains the normal functions of the thyroid, pituitary and adrenal glands, as well as the formation of white and red blood cells.
It plays an extremely important role in stimulating and regulating brain activity. It has the ability to improve mood and stimulate the release of the hormones epinephrine and dopamine.
Benefits of tyrosine
Tyrosine is part of most proteins in the body. In addition, it is the starting material from which the human body produces catecholamines or neurotransmitters - hormones that are involved in the conduction of nerve impulses in the nervous system.
Tyrosine is thought to reduce stress levels in the body. This also applies to the stress that training causes in the body. It reduces depression, anxiety and mental fatigue.
Tyrosine increases alertness; helps reduce coffee consumption; accelerates recovery after training; helps to increase the intensity of training; prevents overtraining.
Tyrosine is an important acid for maintaining a high metabolism. When people reduce their caloric intake during a diet, their production also decreases tyrosinerequired for the synthesis of natural metabolic stimulants.
As a result, there is a slowdown in metabolism and fat burning becomes an increasingly difficult task.
Damage from tyrosine
Tyrosine is contained in a large amount of food and so far no serious side effects have been observed from its use, even in large quantities. This is true for healthy people.
Side effects such as insomnia and nervousness have been reported in only a small proportion of people taking extra tyrosine.
The use of tyrosine supplements is completely contraindicated in people with melanoma, allergies to it and congenital metabolic diseases.
Recommended supplements with tyrosine to be avoided when using antidepressants. Supplemental tyrosine intake can lead to a dangerous increase in blood pressure.
Sources of tyrosine
Tyrosine is found naturally in all proteins of animal or vegetable origin. Particularly rich in this amino acid are turkey, tofu, seafood, yogurt, legumes such as soybeans and beans, tuna.
Intake of tyrosine
The adult should take 2.8 to 6.4 g daily with food. In the case of additional intake through supplements, it is usually taken from 0.5 to 1.5 g per day.
After ingestion, tyrosine is absorbed by the body in the small intestine due to sodium-dependent transport. It is then transported to the liver by the bloodstream.
There, tyrosine is involved in a number of processes. The part of it that is not absorbed by the liver is transported to a number of tissues through the circulatory system.
Tyrosine deficiency
Amino acid deficiency tyrosine can cause low body temperature and low blood pressure, and with prolonged deficiency can cause hypothyroidism.
