2. What is L-Theanine Powder?

 

L-Theanine (γ-glutamylethylamide) is a non-protein amino acid structurally similar to glutamic acid. It is known for its ability to cross the blood-brain barrier and influence neurotransmitter activity related to relaxation and focus.

 

From a formulation perspective, L-Theanine powder is commonly used as a functional active ingredient in:

 

•Cognitive performance supplements

 

•Stress support formulations

 

•Sleep quality blends (non-sedative)

 

•Energy + focus combinations (especially with caffeine)

 

•Functional beverages and RTD drinks

 

Unlike sedatives, L-Theanine supplement ingredient supports a calm mental state without impairing alertness, making it suitable for daytime use products.
