The doctor's favorite for insomnia.
Jacob Teitelbaun, MD, author of From Fatigued to Fantastic!, Pain-Free 1-2-3 and other books has been using L-theanine for years to help his patients improve their sleep quality. "L-theanine is a wonderful herbal remedy that helps insomnia and keeps anxious people calm--while keeping them energized and clear minded," he says.
According to Teitelbaum, who specializes in helping people with chronic fatigue and fibromyalgia, L-theanine stimulates alpha brain waves. There are four types of brain waves, each one responsible for creating a different mental outlook. As Teitelbaum explains it, "Alpha brain waves are associated with an awake yet relaxed, almost meditative, state of mind." Research in Trends in Food Science Technology and other journals backs this up.
