Melatonin is a neurohormone that helps regulate the sleep-wake cycle. Melatonin supplementation can improve sleep and it is a popular natural treatment for jet lag or for use by shift workers.
L-theanine is a unique amino acid from green tea. Studies show L-theanine reduces stress, improves the quality of sleep, and heightens mental acuity by increasing alpha-brain wave activity (for a state of deep relaxation). It reduces beta-wave activity associated with nervousness, scattered thoughts and hyperactivity. L-theanine does not promote daytime drowsiness, but can help those who have trouble falling asleep and staying asleep.
5-HTP can help manage insomnia, especially by increasing Rapid Eye Movement (REM) sleep. In one study, 8 normal subjects were given a total of 600 mg 5-HTP: 200 mg at 9:15 pm, followed by 400 mg at 11:15 pm. A significant increase in REM sleep was observed with 5-HTP.
