Why L-theanine from Life Extension?

Life Extension offers a 100 mg L-theanine (Suntheanine®) supplement. Suntheanine is the only pure form of L-theanine protected by internationally recognised patents and proven in clinical studies to be safe to use. Independent laboratory analyses have identified products on the market that claim to contain L-theanine. In fact, they are only half L-theanine, the other half being a different form of theanine known as “D-theanine” which has not been scientifically evaluated.
