Melatonin is a naturally occurring hormone that your body produces when you sleep at night, most often in a dark room between 10 p.m. and 2 a.m. Melatonin production drops off as you age, so older adults and those with irregular sleep schedules may find it beneficial to supplement their melatonin intake.
In addition to being a highly effective, natural sleeping aid, melatonin is involved in multiple systems throughout the body. As an antioxidant, melatonin helps to give your immune system a boost. It also fights inflammation and decreases aging markers. One recent study also showed that melatonin protects against the hearing damaged caused by some antibiotics.
Further, melatonin has protective effects from indigestion, gastrointestinal reflux (GERD), and other digestive issues.
