The functional properties of L-theanine powder

Hypotensive effect

Blood pressure regulation is mainly achieved through the increase or decrease of catecholamines and serotonin in the central and peripheral nervous systems.

Assisting in tumor suppression

Recent studies have shown that although theanine itself has no anti-tumor activity, it can enhance the efficacy of various anti-tumor drugs. Theanine is very beneficial to clinical chemistry treatment of cancer patients. It not only promotes the effect of some anti-tumor drugs, but also improves the quality of life of cancer patients.

Relaxing nervous tension, relaxation, and other effects

Terashima et al. found that the main receptor for theanine is the brain. After theanine enters the brain through the brain barrier, it significantly increases the neurotransmitter dopamine in the midline of brain cells. Dopamine, a precursor of adrenaline and norepinephrine, is an important substance that conveys the excitability of brain nerve cells, and its release can greatly affect human emotions.. Theanine may reduce serotonin synthesis and increase its breakdown, or inhibit serotonin release.

Caffeine has a refreshing and stimulating effect, and tea also contains a lot of caffeine. Consuming caffeine alone can be harmful to the human body, but drinking tea does not produce the same amount of caffeine's stimulating effect. Kimura and other researchers have proved that theanine has a antagonism on the excitation of caffeine. He measured the amount of spontaneous movement of the central nervous system induced by caffeine, and the results showed that caffeine and theanine have a significant inhibitory effect on the excitation when administered simultaneously. Recently, some scholars have used electroencephalogram evaluation methods to further determine that theanine and caffeine have antagonistic effects on caffeine stimulation at almost the same molar concentration. These fully demonstrate that theanine is a caffeine antagonist with significant calming, reducing tension, and relaxing effects.



Protective effect on cytoprotection of brain nerve

Glutamate is an excitatory neurotransmitter that maintains a concentration of 1mmol-10mmol/L in nerve cells. When cerebral ischemia occurs, the intracellular supply of O2 is interrupted, resulting in a decrease in the production of intracellular energy substance adenosine triphosphate (ATP) and gradual depletion. The nerve cell membrane separates, and excessive glutamate is released into the extracellular space, acting on receptors, causing a continuous increase in intracellular calcium ion concentration, triggering various enzyme activities, and ultimately acting on cells to cause damage and death. And theanine has a competitive protective effect on glutamate receptors, so theanine has a protective effect on brain tissue and can avoid brain nerve cell death caused by cerebral ischemia.

Improving menstrual syndrome

Menstrual Syndrome (PMS) is a condition in which women experience mental and physical discomfort 3 to 10 days before their menstrual cycle. Juneja et al. investigated the improvement effect of theanine on PMS and asked 24 women to take 200mg of theanine daily. After two months, PMS symptoms improved significantly, such as headache, back pain, chest pain, weakness, fatigue, inability to concentrate, and irritability. Further research is needed on its mechanism, which may be related to the sedative effect of theanine.

Weight loss effect

The weight loss effect of theanine powder is the result of the combined action of various components in tea, including theanine, which is particularly effective in reducing cholesterol in the body.

Anti fatigue effect

Theanine can significantly reduce liver glycogen consumption and lower serum urea nitrogen levels during exercise; It has a significant inhibitory effect on the increase of blood lactate after exercise and can promote the elimination of blood lactate after exercise. Therefore, theanine has an anti fatigue effect. The mechanism may be related to the inhibitory effect of theanine on s-hydroxytryptamine secretion and the promotion of catecholamine secretion (5-hydroxytryptamine has an inhibitory effect on the central nervous system, while catecholamine has an excitatory effect)
