“We’re not sure how long these symptoms last, but we do know that some patients have symptoms for at least six months or longer,” the doctor said.

COVID-19 post-infection syndrome is an emerging and unique phenomenon that we are still in the process of understanding. But we know its symptoms, especially extreme fatigue, can have a huge negative impact on a person’s quality of life, affecting family life and work productivity.

How should we deal with COVID-19 post-infection syndrome? Another question, do you usually take L-Theanine?

Tea occupies a very high place in Chinese history. Tea is not just a simple beverage, but also a “tea medicine” that is beneficial to health. In the Tang Dynasty, there was a saying that “tea is the medicine for all diseases”.

Theanine (L-Theanine) is a unique free amino acid in tea. Theanine is glutamic acid γ-ethylamide, which has a sweet taste. The content of theanine varies with the variety and part of the tea. Theanine accounts for 1%-2% by weight in dry tea.

Theanine is similar in chemical structure to glutamine and glutamic acid, which are the active substances in the brain, and is the main ingredient in tea that promotes body fluids and moistens sweetness. The content of theanine is about 1% to 2% of new tea, and its content decreases with the fermentation process.

A general calming effect may usually be noticed within 30 to 40 minutes after taking a dose of 50 to 200 mg of L-theanine and usually lasts for 8 to 10 hours. Moderate anxiety neurosis usually takes 200 mg once or twice a day to produce an effect. More severe anxiety may require doses of 600 mg to 800 mg per day, taken in increments of 100 mg to 200 mg at intervals throughout the day. Unlike benzodiazepines and other anti-anxiety medications prescribed by your doctor, L-theanine may not cause drowsiness, sluggishness, or difficulty concentrating, and there may be no risk of developing tolerance or dependence. There are no reports of serious adverse side effects or interactions between L-theanine and psychotropic agents or other natural products.

People who suffer from COVID-19 post-infection syndrome, can try L-Theanine for anxiety relief, decompress and sleep improvement.

L-Theanine is widely used in Asian countries to combat various medical and mental health problems and is rapidly gaining popularity in Western countries. Caffeine, another major ingredient in tea, may increase levels of acetylcholine and dopamine in the brain, which may improve focus, cognition, and mood. In terms of cognitive benefits, caffeine is more effective than L-theanine because it is absorbed more quickly, reaching peak plasma levels after 30 minutes, compared to plasma levels 50 minutes after ingesting L-theanine compared to peak levels. In addition to theanine and caffeine, tea leaves contain other components that may confer various health benefits, including the amino acids glutamine, arginine, serine, and alanine and the phenolic compounds epigallocatechin, epigallocatechin Theanine gallate, epicatechin and epigallocatechin gallate. Matcha is a special green tea product that contains higher levels of beneficial phytochemicals than regular green tea.

In addition, because theanine can alleviate the bitterness and spicy taste of other foods and effectively improve the flavor of foods, it has been used in the field of food addition. Studies in recent years have also shown that theanine has physiological effects such as anti-tumor, lowering blood pressure, improving memory, and calming the nerves. It can also be used as an active ingredient of a brain function enhancer. It is also widely used in the medical field.
