21st century natural sedative - Theanine
What is theanine?
Theanine is a unique amino acid that exists almost exclusively in tea trees. It can affect the release of neurotransmitters (including GABA) in the brain, making people feel happy. It is a popular natural dietary supplement that relieves stress and promotes calmness, while also increasing mental energy and creating a euphoric mood.
Theanine has been available as a dietary supplement for nearly 30 years. Theanine’s popularity as a dietary supplement began in Japan in 1994, when it was approved as an aid to overcome stress and promote relaxation. This popularity has spread to North America, and theanine can now be found as a key ingredient in functional foods and beverages and dietary supplements designed to produce mental and physical relaxation without causing drowsiness.
What does theanine do in the body?
o Increases brain serotonin, dopamine, and GABA levels
o Counteracts some of the stimulating effects of caffeine
o Produces mental and physical relaxation without causing drowsiness, reduces feelings of stress, and improves sleep quality
o Reduces symptoms of premenstrual syndrome
o Optimizes learning and memory in human and animal studies
o Increases the production of alpha brain waves and decreases the production of beta brain waves

According to many safety studies and medical trials, L-Theanine is safe and has no side effects.
In addition, L-theanine has been used in beverages, foods and dietary supplements since 1994 with no signs of adverse reactions or contraindications. L-theanine, known as Suntheanine, was recognized as a Generally Recognized As Safe (GRAS) ingredient by the U.S. Food and Drug Administration in 2007 and can be used in foods and beverages and as a dietary supplement.

Application of L-theanine in food

L-theanine has the effect of improving food flavor: cocoa drinks and barley tea have unique bitterness or spicy taste, and adding sweeteners will have an unpalatable taste.

Studies have shown that if 0.01% of L-theanine is used to replace sweeteners, the flavor of beverages will be greatly improved. It also has a good effect on improving the flavor of other foods such as coffee, cocoa, ginseng drinks, and beer.

L-theanine has good stability: when a beverage containing L-theanine is heated to 121°C for up to 5 minutes, the L-theanine in the beverage will not degrade. At the same time, L-theanine is also stable when the pH is between 3.0 and 6.6. When the beverage is stored at 25°C for one year, L-theanine shows good stability regardless of whether the solution is neutral (PH6.5) or acidic (PH3.0).
