What is L-Theanine from HSNessentials?

L-Theanine by HSNessentials is a dietary supplement that provides 250mg of L-theanine per capsule.

L-theanine (L-gamma-glutamylethylamide) is an amino acid found mainly in the tea plant (Camellia sinensis). Taking into account that tea is the second most consumed drink worldwide, a considerable dose of theanine is consumed daily worldwide.

The amino acid L-theanine constitutes about 1-2% of the dry weight of the tea leaves and represents 50% of its total amino acids contents.

Theanine, can only be found naturally as a free amino acid (not as part of a protein). This amino acid forms in the root area of the plant and then concentrates in the leaves, where the sunlight transforms the theanine into polyphenols.

It is for this reason that many farmers dedicated to the cultivation of tea, try to plant their plants in areas where the sun does not hit them directly with the intention of maintaining the concentration of theanine, and, thus, also keeping its flavour.
