What Is L-Theanine?
L-theanine is an amino acid found naturally in tea leaves (especially green tea) that has a variety of potential health benefits. It has been extensively studied for its unique mechanism of action and is often used as a dietary supplement. Its chemical formula is C7H14N2O3. Its CAS Number is 3081-61-6, and the molecular weight is 174.20 g/mol.
Sources from
- Tea leaves, especially green tea
The main natural source of L-theanine is tea leaves, especially green tea and oolong tea. It is found in relatively high concentrations in these teas, especially in Japanese Matcha and Gyokuro teas. It is because theanine is absorbed from the roots and accumulates in the leaves as the leaves grow.
- Fungi
It is also found in some types of mushrooms, although in lower concentrations than in tea leaves. For example, some fungi, such as Boletus Badius, Xerocomus Badius, etc., have been found to contain small amounts of l theanine.
- Synthesis way
Today, L-theanine can also be made into dietary supplements by synthesis or extraction. These supplements are usually sold in capsules, tablets, or powders to provide more consistent and precise dosing. Synthetic L-theanine powder is chemically identical to naturally derived powder and, therefore, has similar effects.
Although the main natural sources of L-theanine powder are tea, especially green tea, and some specific mushrooms, it is also a convenient and effective way to obtain it through dietary supplements.
Natural Foods High In L Theanine
Among the most popular source is green tea. The compound is among the many biochemical constituents of green tea responsible for making the said drink useful in promoting relaxation and stress relief. In fact, theanine was first discovered as a component of green tea before being isolated in many other natural sources like black tea. The long-standing belief that green tea may promote wellness is also probably associated with its L-theanine content and other compounds.
What Does L Theanine Do?
As an enhancer of several brain functions, the compound is believed to increase serotonin and dopamine levels. These neurotransmitters play vital roles in regulating hormone balance and overall mood. Hence, it is believed that the compound may help control depression and bipolar conditions associated with imbalances in both dopamine and serotonin. Although Schizophrenia is associated with dopamine imbalance, the dietary supplement product is not intended to cure the condition.
Maintaining healthy levels of brain neurotransmitters is also believed to control anxiety among patients with stress-related conditions.

L-Theanine And Caffeine: The Perfect Combination Of Focus And Calm
These two ingredients are often used together because they have complementary effects, especially in improving attention, focus, and relaxation. Their combination is often used as a supplement to enhance cognition and mood regulation.
First, L-theanine promotes alpha-wave activity in the brain. These brain waves are associated with relaxation and wakefulness. It can help reduce anxiety and stress without causing drowsiness. In addition, although the ingredient itself is not a stimulant, it can improve focus, especially when combined with caffeine.
Caffeine (CAS number 58-08-2) is a stimulant of the central nervous system. It increases alertness, energy, and focus by blocking the effects of adenosine, a neurotransmitter that makes people feel tired. It also improves short-term memory and attention. However, it may sometimes be accompanied by anxiety, nervous hyperexcitation, or increased heart rate.
The combination of L-theanine and caffeine has been widely studied and has been shown to balance and alleviate some of the side effects of caffeine while enhancing cognitive function. Here are some of the main effects.
- Improves focus and alertness
- Reduces side effects of caffeine
- Enhances overall cognitive performance
GABA And L Theanine: The Ideal Combination Of Double Relaxation And Emotional Balance
Both are common ingredients used to help relax and reduce stress. They have similar neuromodulatory effects but work through slightly different mechanisms. Using them together can enhance the effects of relaxation on the brain, helping to improve mood and overall well-being.
Gamma-aminobutyric acid GABA (CAS no. 56-12-2) is an inhibitory neurotransmitter in the brain. It helps relieve anxiety, stress, and tension by reducing overactive neurons, resulting in a relaxing effect. It also plays an important role in regulating sleep. It can improve sleep quality by relaxing the nervous system and reducing insomnia and sleep disorders.
GABA and L-theanine can be used together to simultaneously promote deep relaxation through different mechanisms. GABA directly relaxes the nervous system, primarily through the action of inhibitory neurotransmitters. On the other hand, L-theanine promotes a gentle, relaxed, but alert state by promoting alpha waves.
This combination is particularly effective in relieving anxiety and reducing stress. The fast-acting nature of GABA can help relieve anxiety immediately, while L-theanine provides a lasting relaxation effect. While L-theanine itself does not induce drowsiness, it can work together with GABA to promote better sleep quality, especially when anxiety or stress are causing sleep problems.
Ashwagandha And L-Theanine: Perfect For Relaxation And Concentration
These two ingredients are often used to improve stress management, relaxation, and overall well-being. They each have unique mechanisms of action, and when used together, they may provide combined benefits. Here is a closer look at the two and their potential combined benefits:
Ashwagandha (Withania somnifera), also known as Indian ginseng or winter cherry, is a widely recognized adaptogen that helps the body cope with stress and reduces symptoms of anxiety and depression. Ashwagandha can improve sleep quality and help reduce insomnia. It also helps increase the body’s energy and endurance, improving overall strength and vitality. It is also believed to have some support for the immune system.
When used together, the two can provide a double relaxation effect. Ashwagandha mainly relieves overall stress and anxiety through adaptogenic mechanisms. On the other hand, L-theanine promotes relaxation by promoting alpha waves while maintaining alertness. L-theanine can improve focus, and the stress-fighting effects of Ashwagandha can help reduce the negative effects of stress on cognitive function. When used together, it may help improve focus while managing stress.
Both have a certain positive impact on sleep quality. Ashwagandha can help alleviate sleep problems caused by stress, while L-theanine promotes deep relaxation for better sleep.
The combination of Ashwagandha and L-theanine can support many aspects, including relaxation, stress reduction, improved sleep, and increased focus. Their complementary effects make this duo a powerful natural supplement to support overall physical and mental health.
L Theanine And ADHD: Potential Aids For Focus And Relaxation
- Improves attention and concentration
L-theanine helps improve attention and concentration by promoting alpha-wave activity in the brain. This is especially important for those with ADHD, who often have difficulty in these areas. Its combination with caffeine has been found to significantly improve cognitive performance and attention. For people with ADHD, this combination may help improve concentration in the short term.
- Reduces anxiety and stress
Theanine has a relaxing effect on the nervous system. This can help reduce anxiety and stress, which are common in people with ADHD. Reducing these symptoms can indirectly improve their concentration and learning efficiency.
- Improves sleep quality
For people with ADHD, adequate and high-quality sleep is essential for daily functioning and emotional stability. By promoting better sleep, L-theanine may help improve symptoms of ADHD.
Overall, some preliminary studies suggest that L-theanine may have a positive effect on attention and behavior in people with ADHD. However, the size and methodology of these studies may not be mature enough and need further verification. Current clinical trials are still ongoing to determine its specific effects in the treatment of ADHD. Although preliminary results look promising, more research is needed to confirm its effectiveness and safety.
L-Theanine: Benefits, Side Effects, And More
For better sleep. Based on recent clinical studies, it improves sleep quality and quantity. In a study conducted in 2011, researchers found that persons suffering from General Anxiety Disorder (GAD) who take the compound have experienced an overall improvement in their sleeping patterns and a sense of satisfaction in their quantity of sleep. It is also found in another study that the compound can be beneficial in improving sleep among ADHD patients.
However, the mechanism of action of l-theanine powder is not similar to related products like Melatonin. While the latter is the overall sleep-wake pattern regulator of the body, theanine promotes overall relaxation through interaction with neurotransmitter actions.
For anxiety. Anxiety and its related symptoms are examples of excitatory responses of the human brain. According to the latest medical research, the inhibitory effect of theanine promotes relaxation and controls the development of anxiety symptoms. Another research also reveals that the compound helps reduce stress by soothing the wave pattern of the brain. Experts say that alpha waves in the brain help minimize the development of thoughts that induce stress. Thus, increasing alpha waves reduce anxiety and its debilitating effects.
For weight loss. Statements in customer reviews on the l theanine supplement also show that it may support weight loss efforts. Experts say that theanine in green tea produces a unique taste known as “umami flavor.” The said umami taste is beneficial in reducing appetite, thereby preventing hunger and promoting the metabolism of fats.
When using the supplement to support weight loss, it must be noted that the compound does not treat, cure or prevent the development of health conditions like hyperlipidemia and hypercholesterolemia.
For blood pressure. Hypertension can either be acute or chronic. The use of l-theanine powder, based on studies, is beneficial primarily in cases of an acute increase in blood pressure. For example, blood pressure generally increases during stressful situations as an excitatory response. An acute increase in blood pressure is among the symptom of stress, which may be lessened with the supplementation of theanine.
Side Effects: Is It safe?
Taken within the recommended dosage, no significant side effects are associated with L theanine supplement. However, some customer reports show that the compound may cause irritability and gastric discomfort.
It is important for patients taking medications, especially antihypertensive drugs, to consult their medical doctor before the supplement as it may interact with the action of some drugs. Also, persons diagnosed with certain health conditions are advised to consult their physicians, as the products are not intended to diagnose, treat, cure, or stop the progression of illnesses.
The supplement must also be kept out of reach of children.
L Theanine Dosage Reference
When taken by adults, the safe dose for the compound usually ranges from 250 to 400 mg daily. This quantity is believed to help induce sleep.
For children, theanine is ideal for up to six weeks of short-term use. Oral supplements may be taken at 200 mg, two times daily, among children ages eight to twelve.
Since the products are not intended to prevent any disease but only to supplement the action of certain body chemicals, people suffering from certain illnesses should consult their physician before using the compound.
Also, the safe doses for the supplement and related products depend on the user’s age, weight, body build, and overall health.

FAQs
While many dietary supplements evaluated by the FDA contain only pure L-theanine, Advanced Technology has developed Suntheanine, a patented pure L-theanine.
Suntheanine is believed to be ten times more potent than pure L-theanine. It is also relatively expensive.
Another important difference between pure L-theanine and Suntheanine is that the former can be obtained from natural sources, such as green tea, L-theanine, and black tea. Suntheanine, on the other hand, can only be obtained from dietary supplements that contain the compound.
