L tyrosine instructions for use for weight loss. side effects. The principle of action of the food additive

The amino acid tyrosine is present in every cell of our body and is also found in many protein foods. It is one of the essential amino acids. This means that the body healthy people produces the necessary amount of tyrosine to meet its needs.

general characteristics

Tyrosine, also known by the chemical name 4-hydroxyphenylalanine, is one of the 20 amino acids required for protein synthesis.

And since the human body is able to produce this substance on its own, it is considered a non-essential amino acid. This means that a healthy person does not need additional supplements to provide himself with the necessary amount of tyrosine. This amino acid affects many processes in the body, including the production of neurotransmitters.

The word "tyrosine" comes from the Greek and translates as "cheese". The amino acid got its name in 1846, when it was first discovered by the German chemist Liebig in casein, a protein found in cheese. And his chemical name indicates that tyrosine can also be synthesized from another amino acid, phenylalanine.

There are 3 forms of tyrosine: L-tyrosine is an amino acid found in the proteins of all living organisms, D-tyrosine is a neurotransmitter found in enzymes, DL-tyrosine does not have optical energy.

How it works in the body

In the human body, tyrosine is produced from another amino acid, phenylalanine, but the body metabolizes it in the form of catecholamines, in particular dopamine, norepinephrine, and adrenaline. These substances are able to correct neurophysiological processes such as attention, energy, mood, memory, vigilance. Individuals with inadequate amounts of catecholamines experience different kind cognitive dysfunctions. And the only way to increase the synthesis of catecholamines is to eat foods high in tyrosine and phenylalanine (chicken, fish, turkey). To meet these needs, you can resort to supplements and preparations containing tyrosine. True, in addition to a number of advantages, they also have big amount side effects.

In the body, tyrosine is able to cross the blood-brain barrier and fairly quickly invade the central nervous system. By increasing the level of adrenaline, norepinephrine and dopamine, tyrosine is able to influence wide range processes and functions in the body.

Another meaning of tyrosine is the production and synthesis of additional chemical substances and hormones such as melanin (the pigment that determines skin and hair color). Tyrosine also contributes to the functioning of the organs responsible for the production and regulation of hormone levels in the body. And these are the adrenal glands, the pituitary gland, the thyroid gland. Also directly involved in the creation of almost all proteins in the body.

Benefits of tyrosine:

improves mood and creates a sense of subjective well-being;
increases cognitive functions during times of stress;
protects the body from the effects nervous shocks and anxiety;
improves attention and gives cheerfulness;
promotes the production of dopamine (the hormone of pleasure and happiness).

Functions in the body:

Synthesis of proteins.

One of the main roles of tyrosine is participation in protein synthesis. Human body uses combinations of 20 amino acids to build protein molecules, and tyrosine is one of them. Proteins perform a number of functions in the body. Some control the activity of genes, others contribute chemical reactions or provide structural support for cells. The ability of the body to synthesize proteins allows for the growth of new cells, which is especially important for newborns. And this is a considerable merit of tyrosine.

Brain work.

By consuming tyrosine, you can not worry about the problems of the functioning of the brain. Tyrosine is needed to create the neurotransmitters dopamine and norepinephrine, compounds that transmit impulses between neurons. A cup of invigorating coffee in the morning brings you pleasure? Now, without dopamine, you wouldn't feel it. Maybe some other sensations would have visited you, but without the presence of dopamine in the body, created from tyrosine, the sensations of pleasure would have to be forgotten. As for norepinephrine, it is, so to speak, a close chemical relative of adrenaline and is responsible for the development of memory. So, sitting in the morning with the same cup of coffee, perhaps you remember something pleasant. And again, all this is the merit of a neurotransmitter, but this time norepinephrine. So it turns out that without tyrosine, morning coffee drinking (and not only it) would be much sadder.

Stress and the nervous system.

One of the most interesting potential benefits of tyrosine is its ability to relieve stress. This function is also associated with the production of epinephrine and norepinephrine. A number of studies have confirmed that tyrosine mitigates the negative effects of not only stress, but also cold, relieves fatigue, especially after hard work, and even affects the quality of sleep. In addition, there is evidence that this amino acid increases mental performance and intellectual potential. May be effective tool against depression, as dopamine helps improve mood. It is also believed that tyrosine improves the quality of impulse transmission throughout the body. And scientists from New York University believe that tyrosine increases alertness, especially in sleepy people. But this assumption still requires further study.

Melanin.

Tyrosine also performs a number of physiological functions in the body. For example, this substance is involved in the production of melanin, a protein pigment that gives the skin its natural color and protects from the sun.

Hormones.

The thyroid gland (regulates metabolism and cell growth) and the pituitary gland (controls reproductive health) constantly feel the effects of tyrosine. By increasing the levels of the hormones norepinephrine and epinephrine, the amino acid is able to reduce fat accumulation and suppress excessive appetite.

Side effects

Taking tyrosine as a supplement can cause a number of unpleasant side effects. With extreme caution, the substance should be taken by people with excessive activity. thyroid gland.

Anxiety.

Unexplained anxiety can be a side effect of taking tyrosine. This amino acid affects cognitive abilities, moreover, it acts as a stimulant of the central nervous system. And taking a pharmaceutical analogue of tyrosine can increase the frequency of impulses in the brain several times. Increased fear and panic possible result regular intake of the substance.

Digestive disorder.

Tyrosine in the form food additive affects the health of the digestive system. First of all its not the best best influence feel the mucous membrane digestive tract. Irritation under the influence of the amino acid causes discomfort in the stomach. If blood impurities appear in the stool, you should immediately stop taking tyrosine and consult a doctor.

After getting into digestive system"chemical" tyrosine can develop reflux. Due to the action of the amino acid, the sphincter in the alimentary canal relaxes and passes the contents of the stomach back into the esophagus, causing heartburn and other discomfort.

Migraine.

Migraine in severe and prolonged form is one of the side effects long-term use amino acids. In this case, it is worth stopping taking the drug containing tyrosine and replenishing its supplies exclusively from natural products nutrition.

Tachycardia.

Trembling in the chest can be caused by tyrosine, which, by stimulating the central nervous system, speeds up and increases the heartbeat.

Nervousness.

Influencing the nervous system, it can cause the development of nervousness, which occurs, it would seem, for no reason. In fact, there is a reason - the body's unacceptability of a drug containing an amino acid.

Dependencies.

It is believed that tyrosine helps to more easily cope with addictions: caffeine, drugs, and medications.

Daily rate

Clinical studies show that tyrosine in supplement form can be consumed up to 12 g per day.

Meanwhile, doctors do not advise resorting to such high doses without urgent need. Moreover, an adequate generally accepted daily allowance for healthy people ranges between 1 and 5 grams of the substance (about 16 mg per 1 kg of human weight). This is quite enough for tyrosine to perform its functions in the body qualitatively.

But people with overweight, bad memory, abnormalities in the functioning of the thyroid gland, a tendency to depression or hyperactivity need tyrosine more than healthy people. Also boost daily allowance amino acids can be removed unpleasant symptoms PMS, slowing the development of Parkinson's disease and to improve brain function. Persons who work physically or are actively involved in sports should also take care to get some higher dose tyrosine.

The elderly, hypertensive patients, people with low temperature body and digestive disorders, as well as those with Felling's disease or using antidepressants, on the contrary, it is not advised to abuse supplements containing an amino acid.

Overdose symptoms

abnormal heart rate, hyperexcitability, anxiety, loss of appetite, changes in blood pressure (both upward and downward), chest pain, diarrhea, difficulty breathing, dizziness, drowsiness, fatigue, headaches, heartburn, insomnia, nausea, joint pain, allergic rash, stomach pain, thyroid dysfunction, weight loss. All this possible signs the fact that the body needs less consumption of amino acids.

food sources

Tyrosine is found in many high content foods, and there are over 100 items. Among the most popular: chicken, turkey, fish, peanuts, almonds, avocados, milk, yogurt, bananas, soy products and more. IN in large numbers the amino acid is present in seeds, seafood and beans. But, given that the name of the substance comes from the word "cheese", it is logical that it is in it that tyrosine should be looked for in the first place. In addition, it is found in many products that promote weight loss.

In addition to these products, the daily rate of tyrosine and other useful ones can be obtained from different types cheeses such as gruyère, edam, mozzarella, hard goat, cottage cheese. Among meat products lamb and turkey dishes are also useful. Fish list for good health consists of tuna, mackerel, cod, halibut, as well as shrimp and crabs. As a snack, you should choose healthy seeds sesame, sunflower, pistachios, almonds, pine nuts. In the dairy section, give preference to natural yoghurts and milk. Lentils will help improve memory and mood, different varieties beans, chickpeas and products from whole grain, which also have an increased concentration of tyrosine.

digestibility

The body will better absorb the amino acid if:

take on an empty stomach in combination with vitamins B1, B2, B3, B6, C (you can dilute tyrosine with orange juice) and in combination with the enzyme tyrosine hydroxylase;
drink with St. John's wort, valerian, lemon balm, chamomile, mint (in this case, the effect on the nervous system increases).

Interaction with other substances

Tyrosine with monoamine oxidase inhibitors may increase blood pressure, in some cases call heart attack or a stroke. Taking thyroid hormones against the background of an amino acid can cause hyperthyroidism. But with , ascorbic acid, niacin and reacts positively.

Tyrosine is one of the most important amino acids and an integral part of structural proteins. It can be used to enhance memory and strengthen immune system. But improper consumption leads to hyperthyroidism and other problems.

This amino acid can rightfully be considered a remedy for sadness and depression, a substance that adds strength, energy, mental and physical activity. But to achieve these effects, it is not necessary to resort to pharmaceutical preparations. Nature has everything so that a person can fully draw on the reserves of amino acids from natural foods. Moreover, in this case, they almost never cause side effects.

Most good results received at joint admission drug with methionine and vitamins B6, B1, C. This scheme helps to significantly increase the synthesis of norepinephrine in the brain.

The drug is not addictive.

Tyrosine (L-Tyrosine) is a conditionally replaceable aromatic alpha-amino acid, which is part of the proteins of all living organisms. The synthesis of tyrosine in the human body is possible from, however, this process occurs only when the body needs to get rid of excess phenylalanine, and not in order to restore tyrosine reserves. In this case, reverse synthesis is impossible.

Tyrosine enters the human body with food, but if necessary, its intake can be ensured with the help of biologically active additives.

The amino acid L-tyrosine is most often used in the nutrition of athletes and medicine. Additionally, you need to know the daily intake of tyrosine.

The daily requirement of the body for tyrosine

The daily intake of tyrosine is 3-4 grams. But depending on physical and mental stress, body weight, age, health status and other factors, daily requirement organism in L-tyrosine will change. The exact dosage is selected individually, so visiting an experienced specialist the consequences of a deficiency or excess of this amino acid in the body can be avoided.

The consequences of a lack of tyrosine

The lack of tyrosine in the human body can lead to disorders in the work of the adrenal glands, hyperactivity in children, a fall blood pressure and body temperature, decreased physical and mental activity, muscle weakness, depression, mood swings, weight gain with a normal diet, nervousness, syndrome restless legs, hair weakening, hypothyroidism, drowsiness, loss of appetite.

Consequences of excess tyrosine

An excess of tyrosine in the human body is manifested by an increase in acidity. gastric juice, peptic ulcer stomach, nausea, vomiting, insomnia, a sharp decrease in body weight. It is important that all these symptoms can speak not only about an imbalance of tyrosine in the body, but also be a herald of other diseases. But with an adequate attitude to your health, all this can be avoided and you can only benefit from the use of amino acids, including L-tyrosine.

Useful properties of tyrosine

Tyrosine is essential for proper functioning human body and is a source in the production of important hormones, neurotransmitters and neurotransmitters. From this amino acid, the biogenic substance dopa is formed, and from it, in turn, the body synthesizes dopamine and norepinephrine. Tyrosine is recognized as the best natural antidepressant that fights depression, anxiety, syndrome professional burnout. This amino acid is able to relieve stress resulting from some life situations or training, increases endurance during increased physical exertion and reduces the period of recovery, normalizes metabolism, prevents the deposition of fat, improves work vestibular apparatus which is equally important for athletes. Tyrosine has a positive effect on concentration, relieves headaches, suppresses excessive appetite, supports good health, improves the functional state of the thyroid gland, adrenal glands and pituitary gland. It significantly reduces cravings for alcohol and drugs, and also helps to cope with drug addiction. In addition, tyrosine binds free radicals and acts as an antioxidant. Tyrosine also gives health to the hair and protects it from early gray hair. In addition, as a result of the transformation of L-tyrosine, the production of melanin pigment is noted, without which, in particular, it is impossible to protect the skin from the damaging effects of ultraviolet radiation and radiation damage.

In medicine, L-tyrosine is very successfully used to treat Vitiligo, Parkinson's disease, hyperactivity in children, depression, obesity, poliomyelitis, tuberculous meningitis, allergies, nervous disorders, hypothyroidism, chronic fatigue syndrome and slow metabolism. Tyrosine is also prescribed for PMS, hypotension, complex therapy alcohol, drug and drug addiction.

Contrary to their useful properties amino acid L-tyrosine has contraindications and possible harm. As a rule, this applies to pharmacological preparations and dietary supplements based on it.

Contraindications and harm of tyrosine

Tyrosine is contraindicated in schizophrenia, arterial hypertension, malignant melanoma in history, pregnancy, lactation, hereditary tyrosinemia. Also, L-tyrosine should not be taken in conjunction with antidepressants (MAO inhibitors) and given to children without a doctor's permission.

After taking L-tyrosine in rare cases nausea may occur headache, heartburn, total loss appetite, a sharp decrease in body weight, allergies.

In addition to everything, it is worth knowing which foods are rich in the amino acid tyrosine and, if possible, include them in your diet as often as possible.

Foods rich in tyrosine

The main sources of tyrosine are foods such as: beef, lamb, chicken, fish, seafood, chicken eggs, cottage cheese, milk and cheeses. Tyrosine is also found in almonds, peanuts, bananas, avocados, oatmeal, wheat, soybeans, and pumpkin seeds.

L-tyrosine is a non-essential amino acid that is synthesized in our body from phenylalanine. Despite the fact that this amino acid is not given too much great attention in bodybuilding, applying correctly, you can achieve your goals both in bodybuilding and in life.

Why do you need L-tyrosine?

The amino acid has several functions, including:

Getting rid of the state of overtraining.
Increasing performance and endurance in training.
Improves concentration during training.
Allows you to improve your mood and get rid of the feeling of drowsiness during a training session.

What is most interesting, and, perhaps, useful in this amino acid, is the fact that all of the above benefits of tyrosine apply not only to sports, but also to everyday life. The amino acid allows you to improve concentration in all everyday activities, including work and study. In this connection, the use of amino acids as a dietary supplement is recommended for people with severe mental or physical work. Read also about another interesting sports supplement, This .

No. 1. Improves brain activity
It is difficult to say who needs tyrosine more: people who experience heavy physical exertion, or people who need to keep a lively and clear mind throughout the day.

The fact is that quite recently, in 2014, studies were conducted under the leadership of Lorenza Colzato from the University of Leiden. It all started with the fact that scientists came to the conclusion that some products, which, as it turned out later, contain high concentration of this amino acid, improve creative and intellectual abilities.

When scientists got to the bottom of the “culprit”, which turned out to be tyrosine, two groups of volunteers were assembled who agreed to take part in the experiment. As part of this experiment, both groups were given a glass of orange juice, but in the case of the first group, a tyrosine tablet was dissolved in the glass, while the subjects from the second group were given a “pacifier” - a placebo. Both groups were told that the glass contained tyrosine and their creativity should improve.

However, only volunteers from the first group managed to improve intellectual abilities, and therefore it can be concluded that tyrosine does improve brain activity.

No. 2. Against stress
As we have already noted, the supplement can bring you out of a state of overtraining. However, we are talking not only about training, but also about everyday stress.

L-tyrzine is especially valuable because it is a precursor of the neurotransmitter dopamine. And dopamine is one of the hormones belonging to the group of “happiness hormones”. It is the lack of this hormone that leads to stress and depression, which can manifest itself both in life and in the training process.

So, while glutamine can be called an anti-catabolic that lowers stress hormones, which also helps you cope with depression, tyrosine increases the amount of “happiness hormones”, which ultimately leads to a similar effect.

Hence, high doses glutamine combined with high dosages tyrosine, allow you to comprehensively deal with stress and overwork. That is why both amino acids are often used as a supplement to various energy drinks of a different nature.

No. 3. Fight fat and increase muscle mass
This is a consequence of an increase in dopamine, a consequence of the fight against depression and stress. By increasing the amount of "hormones of happiness", we align our hormonal balance, which leads to a decrease in the effect on the body of stress hormones, which:

Provoke an increase in body fat.
Burn muscle mass.

By using l-tyrosine, we shoot at two “hares” at once. Remarkably, we hit both if we know how to use this supplement correctly.

How to use tyrosine?

By driving into the search engine "Tyrosine instructions for use", we will find recommendations that simply contradict common sense. Perhaps in preventive measures, or for people who do not play sports, 1.5 grams is a sufficient dosage, but this is too little for an athlete.

When calculating an amino acid dosage, always analyze your diet, understanding how many grams of this particular amino acid you are getting per day from food. Just calculate your diet, and you will understand that you get about 10 grams of l-tyrosine per day from ordinary food.

Therefore, one and a half grams can only work if your diet is deficient, and you will receive tyrosine only from a supplement.

Athletes are advised to consume at least 3 grams per day. The time of admission does not matter, but there is a recommendation to take it with a sweet drink. Detailed studies on this subject have not been conducted, but this recommendation is still worth heeding.

It is recommended to use the supplement in courses of one and a half months. One and a half months we accept, one and a half - a break. However, remembering that this is an amino acid, not a medicine, the break between courses can be reduced to 10 days.

Side effects

The additive, in addition to its positive effects, also has side effects. Unlike glutamine or arginine, too much tyrosine in your diet can harm you. We won’t even talk about the absolute harm that some sources talk about, since you get tyrosine daily with food.

However, pregnant and lactating women, patients with Felling's disease, and those who have increased blood pressure after use should not use the amino acid as a dietary supplement.

When to apply?

The amino acid is especially effective during cutting, when your body is in a calorie deficit and needs a powerful supply of protein and amino acids.

First, it has been proven that tyrosine is capable of.
Secondly, the amino acid allows you to save muscles with an energy deficit.
Thirdly, since sufficient dosages can increase the concentration of dopamine in the blood, during drying you will not become depressed, you will not feel weakness and apathy.

Therefore, it is one of the most effective amino acids during the spring-summer period. Of course you can take all year round. In particular, when the body is trying to rebuild from summer to autumn, when “vitamin” food disappears from our tables, and for many, autumn depression begins.

As noted above, tyrosine excellent tool to fight depression. Therefore, if you are suffering from "autumn syndrome", you can now resort to another supplement that changes the hormonal balance in better side. Moreover, now you have instructions for the use of tyrosine.

Tyrosine is a proteinogenic amino acid and is part of the proteins of all known living organisms. Tyrosine is a component of enzymes, in many of which tyrosine plays a key role in enzymatic activity and its regulation. L-tyrosine affects cells and tissues not only directly, but also indirectly, through its influence on the functions of the adrenal glands, thyroid gland and pituitary gland. This influence significantly changes the metabolic processes, having a significant effect on the normalization of the physical state.

Tyrosine is a non-essential amino acid. Formed in the human body from phenylalanine. Tyrosine is the parent compound in the production of the catecholamine/neurotransmitter hormones, including dopamine, norepinephrine, and epinephrine, as well as thyroxine and triiodothyronine. Hormones of the first group are formed in the central and peripheral nervous system, and the adrenal medulla, the second group - in thyroid gland. In addition, as a result of the enzymatic conversion of tyrosine, the pigment melanin (found in skin, hair and choroid eye).

Tyrosine can act as a precursor to dopamine, which is responsible for regulating kidney excretion and blood pressure. In the people, this hormone is often called the “hormone of happiness”, because when its level in the brain increases, mood improves. This happens due to the fact that dopamine turns into norepinephrine, which, concentrating in the brain, just provides the effect of raising mood. Therefore, tyrosine can be used to treat a number of depressive conditions.

Tyrosine, together with adrenaline and norepinephrine, not only affect mood, but also provide energy metabolism. But if the amount of tyrosine is sufficient, the maximum effect of these hormones on lipolysis, glucose mobilization and activation of the nervous system can be ensured. sympathetic system. This also suggests that many important processes in the body depend on the presence of sufficient reserves of tyrosine in the body.

Athletes often use a mixture of aspirin, caffeine and ephedrine, also called ECA. If tyrosine is added to its composition, the effectiveness of the effect increases. But at the same time, the side effects of this composition do not decrease, and it is necessary to use such an “explosive mixture” only under careful monitoring of the state of health. For those who are contraindicated in caffeine, tyrosine supplementation should also be avoided. It is better to refuse the use of ECA altogether, especially since there are safe fat burners.

As many athletes say, the use of tyrosine has a positive effect on concentration and increased motivation. Therefore, tyrosine is used not only by athletes in pursuit of high sports results, but also ordinary people such as managers or workers. This amino acid is useful for overcoming bouts of despondency and raising "spiritual tone".

The use of tyrosine supplements by athletes in sports requiring special endurance provides later fatigue. True, the effect of tyrosine is still insufficiently studied. Athletes who have tried using tyrosine for weight loss report that it leads to a decrease in appetite.

How does deficiency affect the human body?

The lack of tyrosine causes disturbances in the functioning of the adrenal glands, thyroid gland, and nervous system. Vascular regulation worsens, intensity slows down metabolic processes. Negative changes are due to a decrease in the synthesis of important hormones and mediators. Tyrosine deficiency is manifested by the following symptoms:

general weakness and physical inactivity, fatigue;
deterioration of mood, lack of interest in vigorous activity;
overweight without increasing the volume and caloric content of food consumed;
deterioration of memory, concentration of attention, slowing down of thinking;
hyperactivity in children;
restless legs syndrome;
increased fragility of hair and nails.

Without normal amount tyrosine is impossible to reach required quality life, productive activity and creative activity. Supplementation with tyrosine is not recommended for increased function thyroid gland, arterial hypertension. Contraindicated joint application with antidepressants from the group of monoamine oxidase inhibitors (MAOIs).

Despite the importance of this compound in life support, it is important not to overdose. The amount of foods rich in this amino acid consumed should be agreed with a nutritionist. Taking tyrosine in the form biological additive is possible only after finding out the parameters of the functioning of the body and consulting a specialist.

Useful properties of tyrosine

Tyrosine is necessary for the full functioning of the human body and is a source in the production of important hormones, neurotransmitters and neurotransmitters. From this amino acid, the biogenic substance dopa is formed, and from it, in turn, the body synthesizes dopamine and norepinephrine. Tyrosine is recognized as the best natural antidepressant that fights depression, anxiety, burnout syndrome. This amino acid is able to relieve stress resulting from some life situations or training, increases endurance during increased physical exertion and shortens the recovery period, normalizes metabolism, prevents fat deposition, improves the functioning of the vestibular apparatus, which is no less important for athletes. Tyrosine has a positive effect on concentration, relieves headaches, suppresses excessive appetite, maintains good health, improves functional state thyroid, adrenal and pituitary glands. It significantly reduces cravings for alcohol and drugs, and also helps to cope with drug addiction. In addition, tyrosine binds free radicals and acts as an antioxidant. Tyrosine also gives health to hair and protects it from early graying. In addition, as a result of the transformation of L-tyrosine, the production of melanin pigment is noted, without which, in particular, it is impossible to protect the skin from the damaging effects of ultraviolet radiation and radiation damage.

In medicine, L-tyrosine is very successfully used to treat Vitiligo, Parkinson's disease, hyperactivity in children, depression, obesity, polio, tuberculous meningitis, allergies, nervous disorders, hypothyroidism, chronic fatigue syndrome and slow metabolism. And also tyrosine is prescribed for PMS, hypotension, in the complex therapy of alcohol, drug and drug addiction.

Despite its beneficial properties, the amino acid L-tyrosine has contraindications and possible harm. As a rule, this applies to pharmacological preparations and dietary supplements based on it.

Side effects and contraindications

As a rule, adults can safely take small amounts of tyrosine without fear of side effects. However, the recommended dosage regimen should still be followed. Although not everyone is faced with negative consequences taking a nutrient, the possibility of developing side effects, including headache, heartburn and nausea, cannot be completely ruled out. Also, taking tyrosine can provoke the appearance of arthralgia.

Biologically active additives are not medicines, and yet have their own characteristics of the impact on the body. Tyrosine is a fairly active amino acid, so there are a number of limitations.

It should not be used by people with individual intolerance to the components.
During pregnancy and lactation, it is also necessary to avoid taking this drug, since the extra load on the child's fragile body is useless.
It is forbidden to take tyrosine with other antidepressants. Most representatives of this group of drugs belong to the group of monoamine oxidase inhibitors. They additionally affect the rate of dopamine metabolism in the brain.
In schizophrenia, taking the drug is also contraindicated, since the main basic therapy necessarily includes medicines that affect dopamine metabolism in the brain.
It is worth limiting admission to the age of 18 years.

Based on the reviews on the use of L-tyrosine, side effects usually occur when the instructions for use or an overdose of the amino acid are not followed. This can be triggered by taking capsules against the background of active intake of the product with food. An overdose has the following side effects:

allergic manifestations: itching, urticaria, hyperemia;
headache;
fatigue;
insomnia;
nausea;
heartburn;
epigastric pain.

It is worth remembering that uncontrolled intake without prior consultation with a doctor, even a harmless biological additive, can provoke a cascade pathological processes that are difficult to treat.

Application and doses

One-time and daily dose tyrosine is largely determined by the purpose of the application. It is necessary to follow the recommendations indicated on the package, and it is also advisable to consult a dosing regimen with your doctor or pharmacist.

People who suffer from insomnia and take tyrosine in the morning after sleepless night, you may need 1500 mg of tyrosine per day. This maximum dose, which is usually prescribed by adults. The duration of the course of admission is approximately 3 months.

In phenylketonuria, the recommended dose of tyrosine can vary widely, up to 6 grams for every 100 grams of protein consumed. It is important to consult with your doctor in order to choose an adequate dose for the treatment of phenylketonuria and at the same time avoid the development of unwanted side effects.

Some manufacturers of tyrosine preparations recommend taking 5 grams of this amino acid twice a day, but the appropriateness is highly questionable.

Tyrosine: for weight loss

The use of tyrosine for weight loss is primarily based on its ability to activate fat burning and significantly suppress hunger, which is especially important for people who adhere to low calorie diet. In addition, this amino acid inhibits negative impact stress, which also often provokes weight gain.

It is important to note that L-tyrosine, like other amino acids such as arginine, tryptophan or carnitine, is not a panacea against extra pounds. Without proper nutrition its effectiveness is negligible, but in combination with physical activity taking tyrosine guarantees excellent results.

Products containing an amino acid

When answering the question of what foods contain l-tyrosine, it is worth noting dairy products. They contain the protein casein, which includes l-tyrosine. It is worth noting legumes, for example, beans contain 664 mg of amino acids, lentils - 689 mg. Among fruits, the highest content of l-tyrosine is observed in bananas (9 mg), avocados (48 mg), pears (2 mg), plums (8 mg), persimmons (16 mg), oranges (16 mg), cherries (14 mg ). Also, l-tyrosine is found in mushrooms and greens, which is undoubtedly worth paying attention to vegetarians. Champignon mushrooms contain 14 mg, and shiitake - 78 mg of tyrosine. Among the greens, it is worth noting dill, parsley, basil, which contain 96.82 and 77 mg of amino acids, respectively.

People adhering to a raw food diet and not only them should include berries and vegetables in their diet, which include l-tyrosine. For example, berries such as tomato (14 mg), watermelon (12 mg), sultana grapes (10 mg) are very rich in tyrosine. Nutrient-rich vegetables: White cabbage(19 mg), potatoes (50 mg), squash (32 mg), carrots (43 mg), broccoli (50 mg). Among nuts, the place of honor in terms of the content of l-tyrosine belongs to peanuts (1049 mg), but there is also a lot of it in other nuts. For example, almonds contain 452 mg, Walnut- 406 mg, pistachios - 412 mg, cashews - 508 mg.

In addition to the listed products, they are rich in amino acids and pumpkin seeds(1093 mg), sesame (743 mg), meat, fish and seafood. Below is a table of the most commonly consumed foods.

Meat

Legumes

cereals

nuts

Dairy
