Some Amazing Benefits of Green Tea

What if there was a magic pill that would allow you to do a lot of hard work in one sitting and save your mental energy for studying or other tasks? L-theanine is an ingredient found in green tea, black tea, and some supplements. But how effective is it? What are the benefits? Are there side effects? All this information is provided in this article.

L-Theanine: Supplement to Enhance Attention

  • In this age of modern technology, most people suffer from a lack of attention span.
  • Studies of Americans have shown that the average American's attention span is only 5 minutes. It can be said with certainty that it will not be an exception in our country.
  • The popularity of L-theanine supplements is increasing day by day around the world and the market has started to grow at a very large rate.

Most of the supplements that are marketed with such tempting claims have no scientific basis. To be honest, L-theanine manufacturing companies are no exception. Naturally, they sell these things by using colorful words for advertising. But the good thing is, while some of the claims of L-theanine are exaggerated, it does work and has a scientific basis.

Personally, I use this supplement because of my interest in the brain's ability to focus. So I hope to give a clear idea about it. Now let's move to the main part.

What is L-Theanine?

L-theanine is an amino acid component found naturally in green tea and some mushrooms. D-theanine is another amino acid in the theanine group, although it has not been shown to have any effects on the brain.

Green tea contains very small amounts of L-theanine. To get L-theanine naturally through green tea, you need to drink four to five cups of green tea. Which is not healthy at all. This is why L-theanine supplements are taken. L-theanine is an effective solution for those who suffer from anxiety or anxiety. Moreover, it also helps to improve the brain's ability to focus and perform complex tasks. Let's find out how L-theanine works.

How L-Theanine Works

L-theanine binds to glutamate in the brain. Glutamate is a type of receptor in the brain associated with arousal. As a result, tension and anxiety problems are effectively reduced. It also causes the brain to release a hormone called serotonin, which is responsible for good feelings and attention.

Dopamine is called the happy hormone, but serotonin is an important hormone for attention and complex task performance. Dopamine gives you temporary euphoria, but serotonin gives you long-term motivation to do complex tasks and makes you feel good. All these together, L-theanine can be quite effective in increasing brain power.

Benefits of L-theanine

Benefits of L-theanine

The manufacturers claim several benefits of L-theanine. But according to Healthline, it has 6 main benefits. Let's know the benefits. In the next part, I will detail the benefits I got from using it.

Reduce anxiety and stress

L-theanine is very effective in reducing anxiety and stress. The best results are obtained when taking L-theanine with coffee. But the problem with coffee is that it stimulates the nerves, which can trigger anxiety in many people. L-theanine reduces this enzyme. Together with caffeine and L-theanine, the brain's ability to focus and perform complex tasks is greatly enhanced. But if you're just interested in getting rid of anxiety or anxiety, you can take it without coffee.
A study on schizophrenia patients noted the beneficial role of L-theanine.

Increasing attention

L-theanine helps increase concentration and maintain interest in complex tasks when taken with caffeine. Consuming at least 100 mg of L-theanine and 40 mg of caffeine can improve attention. The next part of the article will discuss how much and how to use it.

To increase immunity

Some studies have shown that L-theanine may play an effective role in boosting the immune system. It helps stimulate and boost the body's immune system. There is evidence that L-theanine may be effective in colds and coughs. It can also be very beneficial for infections in the digestive tract. However, more research is needed on the role of L-theanine in health.

Cancer and tumor prevention

L-theanine's anti-cancer and anti-tumor properties have been proven in research. However, the research is still inconclusive because taking it has not been done in large populations to reduce the risk of cancer. However, a Chinese study found that those who drank green tea had a 32% lower incidence of pancreatic cancer. Another study found that among ovarian cancer patients, those who drank green tea regularly after treatment lived significantly longer.

Reduces high blood pressure

Sometimes stressful situations lead to high blood pressure. In those cases, L-theanine plays a very effective role. Caffeine is also effective in this regard, but L-theanine has been shown to be more beneficial.

Good sleep

Several studies have shown that L-theanine is beneficial for better sleep. Taking 250-400 mg of L-theanine promotes better sleep.

Personal experience of using L-theanine

Personal experience of using L-theanine

I got interested in L-Theanine after watching some amazing documentaries on YouTube. After much reading, I decided it was worth a try at least once. Then my honors third-year exam is ahead, which means I have to do a lot of mental hard work continuously. This was a good opportunity to test the efficacy of L-theanine. It works in my experience, but won't make you superhuman like a magic pill. Benefited in maintaining deep concentration. Hard to read and has become a little easier to understand. But the problem is, if you lose focus and move on to other activities, like scrolling through Facebook, you will continue to focus too much. So keep this in mind.

This has something to do with the placebo effect of green tea. Simply put, the placebo effect is when you take a drug that you know will work, but it actually works, and the effectiveness of the drug increases. You'll notice increased performance early on with L-theanine due to a fairly placebo effect. But after a few weeks, you will notice that the work is not the same as before. All in all, in my opinion, if your mental capacity and ability to pay attention for long periods of time is 100%, taking L-theanine with coffee can increase it by 120% or more. However, efficacy is dose-dependent. It also helps to reduce anxiety, but personally, I like to overcome human issues like anxiety without any help. L-theanine can be found at major online supplement stores.

Rules for L-Theanine intake

You can take 200-400 mg of L-theanine with a cup of coffee. You can take one to two times daily to maintain a good mood. You can also take it before doing any complicated work. Since there are no side effects, you can use it at your convenience. But keep in mind, that daily caffeine intake should not exceed 300 mg.

Side Effects of L-Theanine

In general, L-theanine has no side effects or harmful effects. It is also non-toxic, so can definitely be tried. But the problem is, that the possibility of caffeine addiction is very high with regular consumption of coffee. Although caffeine is not harmful, you can avoid coffee if you want to avoid extra caffeine addiction.


L-theanine is an effective supplement in many ways and can provide several additional benefits. But considering the price and performance, I don't think it matters much even if you don't use it. It can be a good medium if you want to increase the motivation to try something new in an important and complex task.
