L-Theanine: Benefits and Uses

L-Theanine is one of the top amino acids for boosting brain health. In addition to helping you with mood, motivation, focus, and better blood pressure and heart rate, L-theanine has been known to enhance both mind and body. It is a special amino acid that is helpful in reducing nervousness while also increasing alertness. Present in green tea leaves, this amino acid helps in a number of ways that have been substantiated through scientific studies.

L-Theanine Improves Mental Functionactivebrain

L-theanine is one of the best ways to quickly boost your levels of awareness and alertness while also reducing jitteriness commonly associated with caffeine. As the precursor to serotonin, it is known to improve both mood and the ability to focus and retain attention better. Several studies have found that L-theanine is positively associated with better mental accuracy, focus, and cognition during complex brain tasks.


As a special neuroprotectant, or an amino acid that blocks the stimulation of cells beyond what they should be receiving, L-theanine also helps to create new brain cells. It helps in boosting proteins that contribute to the growth of nerves, meaning that l-theanine can actually reduce symptoms of currently existing brain diseases while protecting against new ones. L-theanine is known to help in creating dopamine in the brain, as well, and has been shown to ward off Alzheimer’s and dementia as the aging process occurs.

Relaxation Without Sleepiness

L-theanine has been shown to relax the brain through increased alpha waves while also allowing you to focus and stay alert at the same time. You’ll easily be able to enter a creative, concentrated state while using this supplement as part of your regular supplemental process. Helping to boost protective agents of each nerve cell while also being able to cross the blood brain barrier, L-theanine works as well, if not better, than many anti-anxiety products.

You’ll get about the same amount of stress reduction from a single cup of black tea through L-theanine, or with 50 mg of the component through a capsule or supplement form.

Immune System Support

In order to have a healthy mind, your immune system needs to be functioning at top quality. L-theanine has been shown to boost blood vessel dilation through the increased boosting of nitric oxide in the body. This means that instead of increasing cholesterol, fat cell production, and other harmful agents in the body, it keeps your system working in optimal condition. Several nutritional studies have found that L-theanine reduces blood pressure while also boosting your resistance to heart disease.

Better Physical Stamina and Endurance

In addition to creating brain benefits, L-theanine helps to boost physical endurance and stamina. When you can exercise longer and harder, you can also improve mental and cognitive functioning. This supplement helps boost mood and alertness, leading to better workouts and sense of positive energy. You’ll have better stamina as this amino acid helps to produce nitric oxide in the blood stream, leading to better weightlifting pumps as well as cardio benefits.

Enhanced Memory Retention

L-theanine has been found to boost memory retention and recall through a number of different studies. As a neurogenerative agent, allowing new neurons to grow within the brain, this amino acid lets you more easily create new memories while holding on to old ones. Since it helps to solidify existing neural pathways, it is easier for your mind to quickly remember key facts and information necessary for your job or personal life.

Additional Benefits

In addition to helping boost your ability to think quickly, L-theanine can help you build new relationships, succeed at work, and enjoy an overall better quality of life. When your mind functions in optimal conditions, you’ll find it’s easier to concentrate on what those around you are saying while also listening and retaining information.

This will lead to enhanced benefits in your relationships, personal life, and overall interactions with your co-workers and family.


L-theanine is a powerful brain boosting supplement found in tea, as well as through supplements. If you’re seeking powerful brain boosting properties in one simple, safe, healthy supplement, L-theanine is one of the best to include in your daily regimen. Found in dosages anywhere from 50-200mg, you might wish to consult with a physician to determine which dosage is best for you.

This powerful little supplement can help to improve your work and school activities, your relationships, and your overall sense of positive mood, motivation, and capability.
