Amino acids are the<\/span><a href=\"https:\/\/www.humnutrition.com\/blog\/why-do-we-need-protein\/\" target=\"_self\" rel=\"\"> <span style=\"font-weight: 400;\">building blocks of protein<\/span><\/a><span style=\"font-weight: 400;\"> and play an important role in building cells and the synthesis of hormones and neurotransmitters.\u00a0<\/span><\/p>\n\n\n<p><span style=\"font-weight: 400;\">But <\/span><span style=\"font-weight: 400;\">what does L-tyrosine do<\/span><span style=\"font-weight: 400;\">, specifically? The amino acid helps make the starting material for a group of neurotransmitters called catecholamines, which help the body respond to stress. These include:<\/span><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><span style=\"font-weight: 400;\">Dopamine<\/span><\/li>\n\n\n\n<li><span style=\"font-weight: 400;\">Epinephrine<\/span><\/li>\n\n\n\n<li><span style=\"font-weight: 400;\">Noradrenaline<\/span><\/li>\n<\/ul>\n\n\n<p><span style=\"font-weight: 400;\">Additionally, it plays an important role in the production of thyroxine, a<\/span><a href=\"https:\/\/www.humnutrition.com\/blog\/hypothyroidism-vs-hyperthyroidism\/\" target=\"_self\" rel=\"\"> <span style=\"font-weight: 400;\">thyroid hormone<\/span><\/a><span style=\"font-weight: 400;\">.

That\u2019s why L-tyrosine supplementation can help your mind stay sharp when you need it most.<\/span><\/p>\n\n\n<p><span style=\"font-weight: 400;\">Another way that L-tyrosine benefits mental performance is through <\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/25598314\/\" target=\"_blank\" rel=\"noreferrer noopener\"><span style=\"font-weight: 400;\">boosting cognitive flexibility<\/span><\/a><span style=\"font-weight: 400;\">.

Stimulants such as Adderall can help affected individuals ease these behavioral symptoms.<\/span><\/p>\n\n\n<p><span style=\"font-weight: 400;\">Social media users are suggesting that since L-tyrosine plays a role in neurotransmitter production, it can simply replace medications like Adderall. However, there&#8217;s currently no evidence to support that L-tyrosine can do so.<\/span><\/p>\n\n\n<p><span style=\"font-weight: 400;\">In fact, the amount of L-tyrosine needed to effectively raise neurotransmitter levels to an amount that influences behavioral change remains unknown. And unlike L-tyrosine, stimulants like Adderall have hundreds of studies that speak to their<\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/12142863\/\" target=\"_blank\" rel=\"noreferrer noopener\"> <span style=\"font-weight: 400;\">efficacy and standardization<\/span><\/a><span style=\"font-weight: 400;\"> to address such behavioral conditions.<\/span><\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"h-it-doesnt-induce-weight-loss\"><b>It Doesn&#8217;t Induce Weight Loss<\/b><\/h3>\n\n\n<p><span style=\"font-weight: 400;\">In addition to claims of sunless tanning and replacing prescription Adderall, there are rumors that <\/span><span style=\"font-weight: 400;\">L-tyrosine helps with <a href=\"https:\/\/www.humnutrition.com\/blog\/how-much-weight-can-you-lose-in-a-month\/\">weight loss<\/a><\/span><span style=\"font-weight: 400;\">. The logic behind this myth is that it can boost metabolism through its thermogenic effect.<\/span><\/p>\n\n\n<p><span style=\"font-weight: 400;\">Catecholamines, like the neurotransmitters produced by tyrosine, are necessary for the<\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/24736043\/\" target=\"_blank\" rel=\"noreferrer noopener\"> <span style=\"font-weight: 400;\">activation of thermogenesis<\/span><\/a><span style=\"font-weight: 400;\"> and are integral for a healthy metabolism. However, there&#8217;s little data that points to a direct link between tyrosine consumption and pounds lost.<\/span><\/p>\n\n\n<p><span style=\"font-weight: 400;\">The good news? There are a number of studies that showcase L-tyrosine as beneficial for people who experience cognitive or mood problems<\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/11267632\/\" target=\"_blank\" rel=\"noreferrer noopener\"> <span style=\"font-weight: 400;\">resulting from calorie-restricted diets<\/span><\/a><span style=\"font-weight: 400;\">.

There are certain L-tyrosine foods you can incorporate into your diet, such as soy products, turkey, fish milk, cheese, avocados, and bananas, according to <\/span><a href=\"https:\/\/www.mountsinai.org\/health-library\/supplement\/tyrosine\" target=\"_blank\" rel=\"noreferrer noopener\"><span style=\"font-weight: 400;\">Mount Sinai<\/span><\/a><span style=\"font-weight: 400;\">. But you can also take a supplement to boost overall levels effectively. When shopping around for the best L-tyrosine supplement, look at the product label to see it listed in its free form.<\/span><\/p>\n\n\n<p><span style=\"font-weight: 400;\">Compared to its counterpart,<\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/14621123\/\" target=\"_blank\" rel=\"noreferrer noopener\"> <span style=\"font-weight: 400;\">n-acetyl l-tyrosine<\/span><\/a><span style=\"font-weight: 400;\"> (NALT), the free form amino acid simply listed as L-tyrosine has a higher conversion rate in the body.
