Best L-Theanine Brand

L-theanine is a classified as an amino acid found in green tea. It is found primarily in distinct fungal and plant species and was discovered in 1949 from the isolation of gyokuro leaves. L-theanine is now used as a beneficial dietary supplement or vitamin for many health reasons. In this article, I will discuss the benefits and uses of L-theanine and provide you with the best L-theanine brand that is well-researched and scientifically studied and the one I take and fully recommend.

What does L-Theanine do?

Have you ever had green tea and noticed a little bit of a calming effect or relaxation? Well, that is the amino acid L-theanine doing that to you. Interesting isn’t it? Unfortunately, there is not enough L-theanine in green tea itself to get the plentiful benefits they are capable of producing. That is why we take green tea extracts and formulate natural compounds such as vitamins that contain a plentiful amount of the amino acid L-theanine. With supplements, you can expect to gain the right amount of L-theanine you need to thrive during the day. L-theanine

L-theanine is most commonly used for people who experience high anxiety levels. These people my find it hard to concentrate as well as feel relaxed or calm when getting through the day or night. In fact, a number of scientific studies have been conducted on the use of L-theanine for anxiety. In conclusion, these studies have found that L-theanine is most productive and effective in people with baseline or high anxiety levels.

In a Japanese study of the Journal of Physiological Anthropology, an abundance of college students took L-theanine for an effective duration and found that they experienced less anxiety and had their blood pressure significantly reduced when under physical stress compared to when they took a placebo.

In an Israeli study (preliminary) in the Journal of Clinical Psychiatry, L-theanine helped aleviate anxiety symptoms and augment antipsychotic treatment in patients who had schizophrenia (ages 19-55).

There are other clinical studies implemented that have strongly suggested L-theanine supports healthy relaxation and calmness by reducing anxiety symptoms among adults. However, more clinical research is needed to conclude if L-theanine is an effective cure for anxiety. Overall, L-theanine has potential psychoactive properties and the FDA (U.S Food and Drug Administration) has marked it as generally safe to use. This could be attributed to the fact that it is commonly sold online or over the counter. Nonetheless, if you are on any type of pharmeceutical medication, it is best to check with your doctor before consuming L-theanine supplements.

L-Theanine Benefits

I have briefly touched upon the benefits of L-theanine above. I have mainly stated that it is a healthy and natural remedy for those who experience anxiety. It does this efficiently without producing sedative side effects. It does this by converting L-theanine into GABA (gamma-Aminobutyric acid). For those who do not know what GABA is, it is the body’s relaxing neurotransmitter that helps to calm the central nervous system. With an efficiency of GABA, you can expect for the mind and body to be relaxed. Here is a more efficient list of L-theanine benefits. L-theanine for anxiety

    • Reduces anxiety levels
    • Reduces stress
    • Promotes feelings of relaxation and calmness
    • Prevents dementia including Alzheimer’s
    • Improves sleep quality
    • Improves focus and concentration
    • Promotes a healthy state of mind
    • Reduces the negative effects of caffeine (If you find caffeine worsens your anxiety, L-theanine implements a healthy balance that will allow you to consume caffeine without increasing your anxiety levels)
    • Increases the effects of cancer related drugs
    • Treats high blood pressure

Overall, L-theanine is most commonly consumed for its relaxation and calming effects, thereby reducing anxiety levels and stress levels. Even though more clinical research is needed on the use of L-theanine, I strongly support and recommend this supplement. I have been taking L-theanine for months as of now and find it works great with very limited side effects. Here is my recommended supplement I take. I truly believe this is the best L-theanine brand.

My Testimony with L-Theanine

Like I said, I have been taking L-theanine for around 6 months now and haven’t looked back. Before consuming this supplement, I had high anxiety levels. I would find that my heart rate would rise, fear would instill, and sometimes panic would build inside of me. This wasn’t even in high stress situations. This would be a normal day even if I was alone. In stressful or interactive situations, these symptoms would be worse. Once I started taking L-theanine consistently, I noticed a great improvement towards my anxiety levels. I actually noticed a brief effect almost 30-45 minutes after taking it. However, it was around a week that I noticed consistent stress and anxiety-free levels which is sufficient since we have to give this natural supplement time to do its work. If you take this supplement or plan on taking it, give it at least a week or two to show its full effect.

On high stress days or high levels of interaction, I noticed an even greater effect of relaxation and calmness. This is because I expected for my anxiety levels to rise. However, they didn’t which made me ecstatic. I completely recommend this product listed above. I attest that it is the best L-theanine brand and best L-theanine supplement.
