the intake occurs in the morning, the duration of therapy lasts about 12 weeks. In people suffering from phenylketonuria, the dosage is 6 g. per 100 gr. absorbed protein. Many doctors recommend taking a supplement of 5 grams 2-3 times a day. It all depends on the purpose of the application. Tyrosine can be diluted in orange or apple juice.

Natural food containing TYROSINE
In fact, it is not necessary to resort to the use of some sports supplements and dietary supplements to obtain the required daily intake of the substance. It is enough to know which foods contain this amino acid, and in what quantity. Now we will find out. Name of food: Quantity Tyrosine α-amino acids in milligrams (mg): Italian Hard Cheese 1995 Gruyère Cheeses 1776 Whitefish 1740 Roasted Soybeans 1497 Roasted Beef 1386 Pork Chops 1228 Cumin Cheese 1216 Cooked Salmon 1157 Cooked Chicken Breast 1155 Egg 8 Pumpkin Seeds 1157 499 White beans (cooked) 274 Wild rice 169 Factors that increase the chances of side effects from L-Tyrosine L-tyrosine. These factors include factors such as: dosage, individual neurophysiology factors, interactions with other supplements and drugs, duration of use of the substance, frequency of administration, and the specific source of the L-tyrosine alpha-amino acid in question. Dosage and Side Effects At the moment there is a lack of scientific evidence base to accurately determine the safe dosage for a particular case. In certain situations, dosing is based on the person's body weight. According to some recommendations, the introduction of 100-150 mg / kg (body weight) per day is required. That is, people with greater body weight end up taking an order of magnitude more L-tyrosine than those who are in a smaller weight category. Based on some sources, the recommended dosage may be from 500 mg to 2000 mg of L-Tyrosine per day. To minimize the likelihood of side effects and adverse reactions in the body from taking this supplement, the minimum value should be used. In other words, it is recommended to start with a very small dose and gradually increase the amount of supplement used until you feel a noticeable improvement in concentration, mental ability, and so on.

If, for some reason, a high dosage of L-Tyrosine must be adhered to, the fact that the likelihood of problematic side effects increases significantly should be taken into account. Individuality Many of the side effects of L-Tyrosine can be individualized. What does it mean? For example, two people take a supplement at the same dosage. If one person can achieve a significant therapeutic effect without no noticeable manifestations of side effects, while another may experience headaches, nausea and diarrhea. For this reason, you must first consult with your doctor and pass the necessary tests. It is important to understand whether any problems will arise due to a genetic predisposition. Также, как говорилось ранее, необходимо учитывать веса тела, так как дозировка зависит от этого фактора и может потенциально влиять на появление побочных эффектов от завышенных дозировок L-tyrosine. For example, individuals with the disorder phenylketonuria (PKU) are unable to metabolize phenylalanine (the basis for tyrosine synthesis) as a result of a genetic polymorphism. To increase tyrosine levels and ultimately catecholamine synthesis, people with these problems need L-tyrosine supplements. It should be assumed that the polymorphism of some genes may influence the side effects.

In addition to genetics, human neurophysiology (brain waves, neurochemistry, hormones) may influence the side effects associated with tyrosine use. Other individual factors such as body weight, stress levels, diet, sleep, and lifestyle may also influence the positive or negative response to this amino acid. Interactions with other supplements and drugs Also, do not forget that some side effects may result from interactions with alcohol, drugs, anabolic steroids, medications or sports supplements. In addition to increasing the likelihood of side effects, as a result of taking several supplements or drugs along with tyrosine, it will be difficult to determine the cause of the side effects. That is, it will be difficult to understand whether the body reacts badly to an additive, a separate drug, or to the result of their interaction. Therefore, this detail must also be taken into account. Actually, this applies to any used substances. For example, the use of monoamine oxidase enzyme inhibitors with L-tyrosine can increase blood pressure and cause a heart attack or stroke. The interaction of thyroid hormones with L-tyrosine can increase the level of thyroid hormones several times, and cause HYPERTHYROISIS. Because of, Since there are very few studies on the interaction of Tyrosine with other substances to date, the number and severity of all side effects have not yet been determined. This also needs to be taken into account. Before using L-tyrosine, it is very important to consult with your doctor in order to find out in advance about contraindications or possible intolerance to certain substances. Frequency and duration of supplementation With long-term use of tyrosine, the possibility of side effects increases. Many sources indicate the average period of time, which is considered safer for humans. The figure varies from 60 to 90 days. However, it must also be taken into account that even after stopping the use of any supplement, side effects may manifest themselves in the following months. Unfortunately, there is no information regarding "late" adverse reactions of the body. In addition to the duration, it is important to adhere to the acceptable frequency of use of the supplement throughout the day and months. Those people who take tyrosine in the long term with a frequency of use 2-3 times a day are more susceptible to the manifestation of negative symptoms. Data from most studies support the fact that the substance is harmless if taken in the short term - no more than 1 month.

Side effects People over 18 years of age can safely take small doses of tyrosine without fear of negative manifestations. A safe dosage when taking this amino acid is approximately 100-150 milligrams per 1 kilogram of body weight per day for 90 days. Do not exceed the recommended dosage, so as not to cause the risk of side effects. Negative effects are manifested in a small percentage of people in the form of heartburn, migraine, joint pain, fatigue and dizziness. Tyrosine should not be consumed by people with thyroid problems without the advice of a doctor. Since an increase in the level of this alpha-amino acid can lead to a worsening of the situation in patients with autoimmune diseases, including hyperthyroidism and Graves' disease. It is worth refraining from taking tyrosine during the course of thyroid drugs, this combination increases the negative effects of the substances taken. This amino acid should not be taken as a supplement by pregnant women. women, as well as during breastfeeding. Since there is not enough research to date to know for sure whether the supplement is safe for children, as well as new and expectant mothers, it should not be used. Conclusion Tyrosine, branded as L-Tyrosine, is available from NOW over the counter. Also, an extensive selection of triazine and tyrosine-containing supplements is widely represented in various lines of sports nutrition. Reviews about this compound are mostly positive, the only drawback of this drug is a rather high price. Tyrosine helps to get rid of fatigue and drowsiness, helps to improve memory attentiveness in children. The almost complete absence of side effects, with the exception of the presence of problems in people with thyroid diseases, can make tyrosine a very good help in achieving athletic performance. Tyrosine is not a panacea in the fight against excess weight, it only acts as a synergist to diet and exercise.
