Tyr is a form of amino acid that frequently finds its way into weight management pills as well as certain other forms of diet supplement. It is used for a handful of different medicinal reasons because it can produce certain reactions in the body.
While many supplements will list this ingredient as tyr, it can also be identified under a range of different chemical sounding names such as N-acetyl L-tyrosine, Acetyl-L-Tyrosine, 2-Acetylamino-3-(4-hydroxyphenyl)-propanoic acid, tirosina, tyrosinum, or several others.
Tyr is among the amino acids produced by the body by using another type of amino acid called phenylalanine. These substances are used as building blocks for protein . That said, they can also be topped up by eating foods such as nuts, beans, eggs, dairy products, certain meats, fish, oats and wheat.
Many protein supplements used by bodybuilders and athletes contain tyr, as do those produced for individuals suffering from phenylketonuria, which is a hereditary condition that stops the body from being able to properly process phenylalanine. As they are unable to make tyr on their own, they must supplement it.
That said, many people use this substance in order to support their fitness efforts for athletics, body building and weight loss. It is also used to help overcome chronic fatigue syndrome, premenstrual syndrome, to improve alertness when suffering from sleep deprivation, for depression, for attention deficit disorder and even as an appetite suppressant.
Research has indicated that using tyr may indeed be helpful with improving mental performance, enhancing the memory and boosting alertness. Research is continuing to look into its use for boosting exercise performance and results. That said, the current studies have yet to prove that connection. The ingredient is promising enough to warrant the ongoing study it continues to undergo.
Tyr is considered to be likely safe when consumed in food and is also possibly considered to be safe when taken over the short term for medicinal purposes. Medicinal uses can involve oral consumption or using it topically, applied to the skin. In oral doses, it has been safely used in research at a dose of up to 150 milligrams per day for a span of up to 3 months. Beyond that, further study would be required in order to look into the use would continue to be safe over the long term.
This ingredient may not be appropriate for everyone. It has not yet been adequately tested on children or pregnant/nursing women. Moreover, it is suspected that people with thyroid issues may not be able to safely use supplements containing tyr.
