![]() It has been found to up-regulate inhibitory neurotransmitters, and blocks the binding of L-glutamic acid to glutamate receptors in the brain. Once past the blood-brain barrier, L-theanine enacts a variety of neurophysiological and pharmacological effects. Essentially, theanine is better able to get to where it needs to be efficiently. ![]() It uses the leucine-preferring transport system to hitch a ride across the blood-brain barrier, allowing it to target the brain directly. Research shows that 98% of small molecule neurotherapies, and 100 percent of large molecule neurotherapies can’t pass through the blood-brain barrier, rendering many types of common treatments for anxiety almost useless. While this barrier is beneficial, it does have its downsides most notably, it prevents many medications from reaching their target area. The blood-brain barrier is similar to a gateway that prevents blood borne substances from crossing over into the brain it is a form of protection for one of the body’s most important organs. L-theanine is processed in the brain through the blood-brain barrier. ADHD and anxiety coexist in many young people in the United States, so this study further proves that L-theanine can be a large help in the management of anxiety, particularly with sleep disturbances. The boys took 400 mg daily of L-theanine, and the supplement showed no negative side effects. The scientists saw a significant increase in sleep percentage and sleep efficiency scores, and saw less activity during sleep in the boys who took the theanine. Young boys with ADHD were studied to find if theanine would help their sleep. Theanine has also been found to aid in sleep, which is a huge proponent of anxiety. It is actually considered to be an effective anxiolytic, which helps to prevent the brain from producing an anxious response to stressful situations. Its effects are somewhat similar to those of a sedative, but L-theanine is far from this prescription drug. Studies show that increasing intake of theanine can significantly reduce symptoms of anxiety, such as a racing heartbeat and increased secretion of immunoglobulin A in saliva. L-Theanine: A Natural Supplement for Anxiety? This may provide evidence of a link between L-theanine and the treatment of anxiety. When combined with caffeine-like green or black tea-theanine is found to effectively cause improved cognition and attention.Ĭountries that typically have a high green tea intake, like China and Japan, have a much lower rate of depression than western countries, where green tea intake is not as high. It has also been found to aid in sleep quality. ![]() Theanine is found to be relaxing, but not sedating agent, and has been found to help process stress and to improve attention. L-theanine is present in various food sources but is found mainly in both green and black teas. L-theanine is often called a “nondietary amino acid.” Because of its structure, theanine is known to reach the brain quickly following oral consumption. Theanine is an amino acid that is not commonly found in the human diet, as it is not one of the essential or nonessential amino acids. Professionals typically agree that theanine could potentially be a strong anxiety treatment. One of these compounds is theanine, or L-theanine. ![]() They have found that the calming effects of L-theanine compensate for the stimulating effects of caffeine found in teas like green tea and black tea.Įxperts believe that diet could play a large role in anxiety treatment, and that foods high in specific compounds could hold the key to improved mental health. Green tea has been used as a restorative medicine in traditional Chinese medicine for a very long time, and now L-theanine has been extracted from green tea to treat anxiety and depression in China, Japan, and other countries in Asia. But what are some of these safe, natural ways to treat anxiety? ![]() It has been estimated that 1 in 5 people people in the world are affected by depression and/or anxiety.Īnxiety and depression are often treated in a similar way - with antidepressants - but as these drugs can often have serious side effects, more and more people are starting to look into natural anxiety and depression treatments. Almost 10% of the world’s population is affected by anxiety or depression, and mental illnesses including these account for a third of the global non-fatal disease burden, especially economically. In fact, between 19, the number of people suffering with anxiety and/or depression rose by 50%. Anxiety is an extremely common mental health illness in the United States and the rest of the world, and it is becoming increasingly prevalent. ![]()
