L-tyrosine is a non-essential amino acid, which means you do not need to get it from your diet. It is produced by the body utilizing another amino acid, phenylalanine. It is possible to find Tyrosine in supplement form, either with or without the letter “L.” Tyrosine can be found in all tissues and fluids of the human body. It aids in the formation of proteins in your body, as well as the production of enzymes, thyroid hormones, as well as skin pigment melanin. It also aids in the production of neurotransmitters, which help in the communication of nerve cells.
Tyrosine is crucial in the synthesis of adrenaline, norepinephrine, and dopamine. It aids in the formation of essential brain chemicals that influence mood and sleep. The majority of individuals do not need L-tyrosine since their systems contain a method for controlling tyrosine supply. If you don’t get enough Tyrosine from your diet, your body may produce extra. If you overeat, your body may break it down and eliminate it.
Health Benefits of L-Tyrosine
Amino acids, such as Tyrosine, are used by the body to generate chemical messengers that affect brain states like alertness. Natural dietary L-tyrosine enters your metabolism like all other nutrients. To get the advantages of nutritional sources, you must simply let your digestive and metabolic systems do their job. L-tyrosine from supplements enters your system immediately. You’ll see the effects of this pre-workout supplement within minutes of consuming it. L-tyrosine is virtually instantly accessible to your muscles and mind when consumed as a nutrition drink or supplement.
The health benefits of L-Tyrosine are numerous. It can help to improve your mental and physical health in many ways.
Despite the fact that most individuals do not need L-tyrosine, it may be advantageous in a number of situations, including the following:
Phenylketonuria
Phenylketonuria (PKU) is a genetic metabolic condition in which people cannot effectively break down phenylalanine. As a result, the accumulation of phenylalanine causes brain damage, including cognitive impairment. Tyrosine is found in medicinal meals for persons who have phenylketonuria. To reduce phenylalanine consumption, these patients should adopt a low-protein diet. They should also include Tyrosine as a component of medicinal meals or take Tyrosine supplements. Because the body turns phenylalanine into Tyrosine, this lowers the chance of tyrosine deficiency. Tyrosine supplementation has been found to be helpful for people with this condition.
Mood and Cognitive Ability
An analysis of 15 clinical studies looked at the impact of L-tyrosine loading — brief bursts of higher dosages – on cognition and behavior in both healthy and diseased individuals. In stressful and challenging conditions, this dosing strategy avoided catecholamine depletion and improved mental performance. One study even found that cadets who took tyrosine experienced improved cognitive performance and lower blood pressure.
There is currently not enough evidence to support the use of L-tyrosine in the treatment of depression and other mood disorders. However, dietary sources of L-tyrosine may improve mental health. Some scientists believe that abnormalities in brain neurotransmitters have a role in sadness and other mood disorders. Tyrosine may work as a dietary mood booster since it promotes the generation of dopamine and noradrenaline. Initial studies have shown that it may help with moderate depression and ADHD.
Furthermore, L-tyrosine may be useful for people struggling with addiction. Dopamine is essential in the reward system of the brain. Scientists initially hypothesized that it made some things (such as eating and sex) more pleasurable. According to a new study, dopamine does not help us experience pleasure; instead, it makes us crave it. The depletion or over-sensitization of this pathway in those struggling with addiction may lead to an increase in cravings and drug-seeking behavior.
Thyroid Health
The body uses selenium to mix Tyrosine and iodine to create thyroid hormones. During the severe winter, supplementing with high doses of L-tyrosine (12 g daily) marginally enhanced T3, the active thyroid hormone, in 85 participants. It also significantly lowered TSH, which is related to hypothyroidism and stress. In rats subjected to continuous pressure, tyrosine treatment reduced thyroid hormone reductions.
May Help with Weight Loss
Many nutraceutical products are marketed to help people lose weight, but most have not been backed by substantial clinical evidence or authorized by health authorities. The only techniques for losing weight that has been scientifically validated are a calorie-controlled diet and increasing physical activity. Tyrosine provides catecholamines as well as thyroid hormones, both of which boost metabolism and energy generation. As a result, many individuals want to know whether L-tyrosine may help with weight reduction.
Final Thoughts
L-tyrosine is indeed an amino acid that the body uses to make proteins, and neurotransmitters, including thyroid hormones. Protein-rich foods like meat, eggs, cheese, and beans are the most acceptable dietary sources. When people are stressed, they use L-tyrosine supplements to improve cognitive function and alertness, which is backed by minimal research. It is unlikely to aid in the treatment of depression, attention difficulties, or physical performance. Headaches, stress, and nausea may occur as a result of L-tyrosine intake. Pregnant women, children, and those using L-DOPA or thyroid hormones must avoid it unless a doctor has recommended it.
