In today’s fast-paced society, a large portion of the adult population experiences some form of stress during their daily life. Since ancient times, it has been said that drinking green tea induces relaxation. It has been found that this relaxation effect can be attributed to the presence of the amino acid L-Theanine.

Suntheanine® is the trade name for our patented high purity L-isomer-specific L-Theanine (chemical name: L-glutamic acid-y-monoethylamine), a unique amino acid found in tea (Camellia sinensis). Suntheanine® is produced via a patented enzymatic method, resulting in an isomerically pure L-Theanine.

Suntheanine® is the original, patented, and consumer recognized high purity L-isomer-specific L-Theanine; an award-winning and patented dietary ingredient for stress, relaxation, focus and improved sleep efficiency, which is currently used around the world by food, beverage, dietary, animal health and sports nutrition brands.
