What is l-theanine?
L-theanine is found in tea leaves and is partly why tea feels calmer than coffee. It promotes relaxed alertness and, with caffeine, smoother focus. Studies also suggest it may help people fall asleep and sleep better when stress is the problem.
Forms. Capsules and tablets, usually 100–200 mg.
