Theanine is an amino acid that is most commonly found in tea leaves and some fungi.
It is used to improve mood and reduce stress levels and to protect the brain and heart.
Theanine usually refers to L-Theanine, which has more health benefits than D-Theanine.
Patients taking L-theanine performed mental tasks. Compared to patients who took placebo, they had lower symptoms of stress with reduced blood pressure and blood pressure.
Daily supplementation in patients with schizophrenia leads to a reduction in the level of anxiety.
Theanine also supports relaxation in healthy patients. Additional doses of theanine, which promotes relaxation, do not cause sedation or dementia. In addition, L-theanine can also stimulate when given in lower doses than those that promote relaxation.
L-theanine supplementation helps to increase attention and improve memory.
In men and women who have had minor brain damage, the combination of L-theanine and green tea extract has increased the ability to remember during mental exercise. This was done by reducing the delayed recognition during the memory test.
During the memory test, the attention and vigilance of the subjects were increased.
Improvement in attention was also noted in healthy people who are susceptible to anxiety.
L-Theanine improves the function of blood vessels by increasing the production of nitric oxide.
It also prevents the oxidation of LDL fat (low-density lipoprotein), which reduces the risk of arterial cure.
Teina also reduced blood pressure in hypertensive rats.
L-theanine in tea exerts antioxidant effects.
It also restores the antioxidant capacity of liver cells that prevents its injury.
In rats, it reduced oxidative damage and stopped inflammation.
Taking 400 mg daily for eight weeks resulted in a reduced number of symptoms of schizophrenia. Patients reported lower levels of anxiety, less severe symptoms and reduction of muscle problems.
Theanine, along with other components of green tea, reduce the concentration of triglycerides and fatty acids in the blood. In the mice treated with theanine, the intake of food and body weight decreased.
It also reduces the toxicity of these drugs to healthy tissues.
In a recent open study, taking L-theanine for eight weeks helped to reduce depressive symptoms, anxiety, sleep disorders and cognitive impairment in patients with major depressive disorder.
