What is L-Theanine?

L-theanine or Theanine is an amino acid, present only in green tea. A larger percentage of the amino acid needed by the body to function effectively are either produced in the body system or readily available in our diet. This isn’t the case for L-theanine. It’s a very rare amino acid found only in tea leaves and some fungal species. What this implies is that; if you want to enjoy the benefits that the amino acid offers; then you have to source for it through supplements. The aim of this article is to discuss in details what L-theanine supplement does and also offer a good recommendation on the best L-theanine supplements in the market. L-theanine has an enantiomer, the D-theanine. Very few research work has been done to examine the effectiveness of the D-theanine since the most prevalent type is the L-theanine. Even though D-theanine is less discussed, it’s been shown that they are usually present in most theanine supplements; albeit in minute proportion. One of the unique characteristics of L-theanine is its ability to cross the blood-brain barrier; which is like a filter that prevents the absorption of materials into the brain cells.  The structure of L-theanine is very similar to a neurotransmitter called glutamate. Glutamate is an excitatory neurotransmitter. The ability of L-theanine to cross the blood-brain barrier makes it an antagonist on glutamate receptor. It also increases the level of serotonin; an inhibitory neurotransmitter. This results in various psychoactive effects, which will be discussed in details in later part of this guide.

Benefits Of L-Theanine Supplements

Fix For Stress and Anxiety: The major reasons why people take L-theanine is to calm their nerve against anxiety. If you’re prone to anxiety, then you would want to take less of caffeinated drink and opt for theanine. The supplement is capable of interacting directly with the brain cells to reduce the presence of glutamate which is an excitatory neurotransmitter. Improve Cognition and boost mood: L-theanine has been associated with the increase in alpha brain wave during the scan. Research has also shown that alpha brainwave is associated with increased creativity and reduces depression. Inhibit Glutamate Excitocity: Accumulation of glutamate in the cell usually result in excitotoxicity due to the excessive stimulatory action of the neurotransmitter. Since L-theanine is similar in structure with glutamate, then it shares it’s receptor by binding with them as an antagonist, thereby reducing the overall impact of the neurotransmitter on the cell. Improve sleep quality in people with ADHD: Although not a sedative, the supplement has been reported to improve quality of sleep by getting rid of anxiety and making user calm; especially in those with ADHD. Improve learning and memory: It’s been reported to have a direct impact on the learning and memory of users. This is explainable based on its ability to cross the blood-brain barrier and act as a psychoactive. There are other benefits such as treatment of stomach cancer, asthma etc, but the effect is not well documented in these cases and the further test must be conducted before it becomes an ascertained fact.

What is the Right Dosage OF L-Theanine

Drug or supplement dosage depends on a wide range of several factors, from body weight to tolerance, as well as age. However, based on general consensus, from frequent users; it’s been reported that 200mg is the average dose required to elicit the desired effect. This explains why taking green tea does not give the desired result. Because a typical cup of green tea contains just about 25mg of L-theanine, to get the desired result that supplement will give, about 8 to 10 cups of green tea must be consumed to attain the average dosage. It’s important to take note that tea does not just contain L-theanine, it has other ingredients as well, such as caffeine Conclusion: There have been reports that taking this supplement alongside caffeine gives a whole new level of experience. It’s important to understand your body system before you load up on dietary supplements generally. Ask questions when you’re not clean about the ingredient of a particular product and go the extra mile getting the answer before taking the supplement.
