L-theanine supplements
L-theanine is a water-soluble amino acid that is very similar to the amino acid glutamine. This substance does not belong to the essential or non-essential amino acids and is also not incorporated into body proteins. This means that the body does not need this amino acid to build proteins. The substance L-theanine is mainly found in green tea (Camellia Sinensis). But recently it has also been discovered that certain mushrooms (Boletus badius) also contain L-theanine.
History of L-theanine
L-theanine was first identified in 1949 by a Japanese scientist. He concluded that this substance is responsible for the characteristic taste of green tea. This characteristic taste, also called umami (meaty), was later linked to all kinds of health benefits. L-theanine is also said to change taste perception, so that you taste less "bitterness".
How L-theanine Works
L-theanine has been known for years for its supposedly calming properties. This also makes it a very popular food supplement, which is used in all kinds of products: natural sleeping pills, nootropics and supplements that help you relax. Although a lot of people use L-theanine daily as a food supplement, no claims may be made about the effects of this natural amino acid. This has been decided at European level. We use L-theanine in various supplements of ours:
