Amino acid L-theanine (γ-N-ethylglutamine), which is naturally present in tea leaves and edible Boletus serrata (scientific name: xerocomus badius). Green tea and black tea come from the same plant. Black tea is made by fermentation while green tea is not. Green tea has been a mainstay of traditional Chinese medicine for over three thousand years, and it is used as a potion with other herbs and on its own as a concentrate designed to enhance stamina and concentration. The amount of L-theanine depends on where the tea tree was grown, how it was made, and when it was harvested. Different types of tea such as Pu-erh have higher levels of l-theanine than the better-known camellia. there is also a synthetic form of L-theanine (suntheanine).
Theanine (sometimes referred to as "L-theanine") is an amino acid found naturally in green tea. Also available in supplement form, theanine is said to offer a number of health benefits.
Proponents claim that theanine can help with the following health problems:
1. l-theanine powder for anxiety;
2. l-theanine powder for depression;
3. l-theanine powder for high blood pressure;
4. l-theanine powder for high cholesterol;
5. l-theanine powder for Insomnia;
6. l-theanine powder for stress.
People use L-theanine to improve mental function. It is also used for anxiety, mental impairment, stress, and other conditions.
Depending on the relative amounts of L-theanine and caffeine in a particular kind of tea and how it's prepared, individuals who drink green tea to reduce stress or anxiety may experience greater calming effects than stimulation. A general calming effect may usually be noticed within 30 to 40 minutes after taking a 50 to 200 mg dose of L-theanine and usually lasts 8 to 10 hours. Moderate anxiety neurosis usually occurs after taking 200 mg once or twice a day. More severe anxiety may require a daily dose of 600 mg to 800 mg, taken in 100 mg to 200 mg increments throughout the day.
Theanine can be used together with GABA or inositol: theanine 200 mg, GABA (200-500 mg) or inositol (500-1500 mg).
