It is also thought to have some anti-depressant effects. Some people find that taking L-theanine before bed helps them get a good night’s sleep.
Dosage for L-theanine
L-theanine is a natural amino acid that can be acquired through green tea consumption. Dosages for L-theanine vary depending on the product, but generally ranges from 200mg to 800mg. Studies have shown that L-theanine can improve mood and cognition, but should be taken with caution as it can cause drowsiness.
L-theanine benefits
This natural constituent in green tea has been shown to have many benefits for mental health. In particular, it has been shown to be effective at improving mood, focusing attention, and reducing anxiety. L-theanine is also known to help improve sleep quality and reduce cognitive decline in older adults. Other benefits of this natural amino acid is discussed below.
Increased focus
L-theanine, an amino acid found in green tea, has been shown to increase focus and attention. In a study published in the journal Nutritional Neuroscience, participants who took L-theanine for six weeks showed improvements in their ability to focus and pay attention. The researchers suggest that L-theanine might help improve cognitive function by helping to reduce anxiety and stress.
Anxiety and stress relief
L-theanine is an amino acid that has been shown to promote relaxation and help reduce generalized anxiety disorder anxiety and stress. It also works by acting as a mood-altering neurotransmitter, helping to improve brain function and lowering arousal levels. Additionally, Theanine reduces psychological and physiological stress responses.
Blood pressure management
Increasing intake of L-theanine has been shown to decrease blood pressure in pre-hypertensive and hypertensive populations. In a study with 24 patients, daily ingestion of 250 mg L-theanine for eight weeks lowered systolic BP by 6.6 mm Hg and diastolic BP by 2.1 mm Hg compared to the control group. Benefits were seen despite no changes in other cardiovascular risk factors. It is thought that L-theanine works via relaxation of vascular smooth muscle cells, which reduces blood pressure by reducing extrusion of blood from the ventricles.
Tumor and cancer treatment
L-theanine is a natural compound found in green tea that has been shown to have anti-cancer properties. It has been shown to help reduce tumor size and promote cancer cell death. L-theanine is also known to improve cognitive function and mood, making it an ideal supplement for people with cancer.
Better immunity
L-theanine has been shown to improve cognitive function, reduce anxiety and stress levels, and boost immunity. In a study published in Nutrition & Metabolism, researchers found that L-theanine improved the function of white blood cells and helped prevent infections. The researchers also found that taking L-theanine in supplement form improved the function of white blood cells and reduced infections. In another study, it was found out that L-theanine could help decrease upper respiratory tract infections. Specifically, green tea catechins such as oxidants and theanine are said to be effective at preventing the flu.
L-theanine risks and side effects
L-theanine, a constituent of green tea, has been reported to have anxiolytic effects and protect against neuronal damage. However, L-theanine also appears to possess some risks, including adverse reaction profiles, hepatotoxicity, neuropsychiatric side effects and even addiction potential in certain individuals. As such, it is important to be aware of the potential risks and benefits of using L-theanine before making any decisions about its use.
What is caffeine?
Caffeine, also known as the “energy drink of the world,” is a psychoactive stimulant found in various plants and products. It can be found in coffee, tea, cola, cocoa, guarana and other foods. Caffeine is a central nervous system stimulant that increases energy and alertness.

L-theanine and caffeine: What are the secrets of their relationship?
Recent studies have shown that caffeine and L-theanine working together in combination affect human cognition as evidenced by oscillatory alpha-band activity and attention task performance. Scientists aren’t sure why this is, but they think that the two substances may work together to improve attention and subjective alertness. L-theanine is a natural compound found in green tea and other plants. It is often used as a relaxant and has been linked to improved moods and sleep quality. Coffee also contains caffeine, which is why some people believe that the two substances work well together.
