Amino acids Endogenous nutrients play a crucial role in the proper functioning of the body, and as long as we're getting the right nutrients, there's no need to worry about their levels. However, there are situations where supplementation is worth considering. If we're suffering from chronic stress, engage in physical labor, or engage in a lot of exercise, and don't maintain a proper diet, Tyrosine supplementation may prove necessary. It is a precursor to neurotransmitters and thyroid hormones, so its levels influence various functions.
What is tyrosine?
It belongs to the group of 20 essential protein amino acids. It is also a non-essential amino acid, meaning the human body can produce it on its own if it receives adequate amounts of another amino acid, phenylalanine. Studies have shown that 70 percent of consumed phenylalanine is converted into tyrosine. People whose diet is rich in protein should not be concerned about their levels of these amino acids. The highest amounts of tyrosine are found in meat, eggs, milk and dairy products, legumes and nuts..
Tyrosine is a precursor of dopamine, which in turn can be converted into adrenaline and noradrenaline. It is also the starting compound for production of triodothyronine and thyroxine, which determine the proper functioning of the thyroid gland. It is also responsible for melanin production, pigment that determines skin and hair color. This amino acid is also needed for collagen formation, takes part in the synthesis of ingredients forming coenzyme Q10.
What is l tyrosine needed for?
The two most popular theories about tyrosine supplementation suggest its effect on mood and exercise performance. However, numerous studies have failed to confirm either of these effects. Although tyrosine is indeed needed for dopamine production, supplementation is not a "recipe for a good mood," contrary to what some claim. Physical performance also appears to be independent of tyrosine, unless we're talking about people who exercise intensely or follow a weight-loss diet. Every human body has different needs, so it should be approached individually.
They are also confirmed effects of tyrosine supplementation: improves concentration, ability to associate and remember – especially during stressful situations. Some studies also indicate the usefulness of supplementation in cases of phenylketonuria or narcolepsy.
Regardless of the potential effects of dietary supplementation with tyrosine, it is an amino acid necessary for the proper functioning of the body, and its deficiency may be associated with with serious consequences. Low levels of tyrosine can cause mood disorders, excessive sleepiness, problems with memory and concentration.. Chronic tyrosine deficiency can lead to thyroid dysfunction and, consequently, even hypothyroidism.
Excess tyrosine It's extremely rare, and is most often the result of innate tendencies or an extremely rare condition called tyrosemia. Overdosing on tyrosine from supplementation or excessive amounts in the diet is difficult, but it's still important to follow the recommended dosage when taking dietary supplements.
How to use tyrosine dietary supplements?
There are many preparations containing tyrosine – they are available in capsule form or powder form for dissolving in liquids. When choosing one, it's worth paying attention to the manufacturer's reputation and, consequently, quality. product. As with other dietary supplements, it's best to choose those with the purest ingredients. It's also worth paying attention to the dosage per capsule and the presence of additional ingredients. It's recommended Use 100-150 mg per kilogram of body weight. Keep in mind that using doses higher than recommended will not produce any effect. Tyrosine can also be found in protein supplements and multi-amino acid supplements.
Before adding tyrosine to your supplementation regimen, it's a good idea to consult a doctor and assess your levels and needs for l-tyrosine (the levorotatory isomer of tyrosine). People with hyperthyroidism and Graves' disease should exercise particular caution when supplementing – excessive doses of tyrosine can worsen both conditions. Tyrosine also interacts with levodopa and MAO inhibitors, so they should not be used concurrently. Tyrosine supplementation is not recommended for people suffering from migraines, and it should also be avoided by pregnant or breastfeeding women.
L-tyrosine is considered a safe agent, but it may cause minor side effects such as insomnia, nausea or headaches.
Who should use tyrosine and when?
Given that tyrosine is an endogenous amino acid, which we obtain through diet, supplementation should only be considered in situations that indicate an increased need. These include times when we are exposed to greater stress or increased intellectual effort. Supplementing with tyrosine will help maintain good physical and mental health, as well as improve concentration and emotional balance. Tyrosine may also help curb appetite, but it is not a weight-loss aid.
