What is Theanine?

Green tea is rich in the amino acid, theanine.

Theanine is an amino acid, found in tea leaves, most concentrated in the green tea leaf gyokuro. Theanine is also present in one mushroom species, the Boletus badius. Highly valued for its health benefits, specifically its effect on mental health, theanine makes up 50 percent of the amino acids in green tea. Although theanine is most concentrated in green tea, it also appears in several types of white and oo-long teas. In 1950, theanine was extracted from the gyokuro tea leaf, so there are other ways to get theanine than through tea. Theanine can be purchased in powder, pill and supplement form.

Benefits of Theanine

The major reason theanine is so nutritionally valued is its ability to cross the blood-brain barrier. In other words, theanine can enter your brain, and therefore can have psychoactive benefits. Theanine can reduce stress and increase relaxation, as well as help with cognition, especially when taken in with caffeine. Regularly ingesting theanine can increase levels of serotonin and dopamine, which can ward off depression and anxiety. It has also been shown to boost the immune system and help the body fight against diseases (amazing-green-tea.com).
