Your Expert Guide To L-Theanine

L-Theanine is a natural non-dietary amino acid found nearly exclusive in tea from the Camellia Sinensis plant alongside Green Tea Catechins and Caffeine. Non-dietary amino acids are neither part of the categories pertaining to essential amino acids or the most common non-essential type. L-Theanine is more closely related to other active ingredients in PuriSure products such as L-Citrulline, GABA, and Glutamate. This ingredient brings about several changes in the brain that result in relaxation and better sleep among many other benefits.

Since L-Theanine is the main amino acid found in green and black tea, it is pinpointed as the source of the drink’s benefits for mood enhancement and calming effects. It works effectively with Caffeine to provide mental alertness, focus, and concentration you need to move across the daily grind. The synergistic effect it has with Caffeine and other stimulants make it a perfect pre-workout supplement.

Why Do We Use It?

L-Theanine is present in some of the supplements offered by PuriSure because of its benefits for improved brain power and fitness. This amino acid increases Alpha-1 brain activity which is responsible for improving focus, cognition, learning, and creativity. Through the process known as neurogenesis, this powerful ingredient improves memory by creating healthy neurons in the brain.

Moreover, it also functions as a relaxing agent without the negative impacts of sedation. This is made possible through promoting good cortisol levels which also helps you get better sleep. The way it works effectively without sedation makes L-Theanine a great component of stimulants without the jittery side effects.

Interesting Information About L-Theanine

  • The tea leaves from where L-Theanine is derived come from the evergreen shrub of a tree native to eastern Asia. It is notable for its dark green, oval-shaped alternative leaves with white, aromatic blossoms that appear in clusters. This tree grows to more than nine meters in height.
  • L-Theanine has also been derived from a mushroom called Boletus badius. This edible mushroom is usually abundant during later summer and fall seasons in the United States. It is characterized with reddish to dark brown color, with flesh in white and yellow color varieties.  
  • It was only in 1949 when this ingredient has been discovered as a component of green tea. In 1964, it was approved in Japan to be used in food products. Some of these food sources include sodas, chocolates, and herbal teas.
  • This amino acid also produces a distinctive umami flavor similar to those found in cooking mixes. It also gives the flavor to green tea drinks.
