Melatonin is the hormone produced by the pineal gland that signals darkness to the body and initiates the sleep cycle. While commercial supplements often contain 3-10 mg, research consistently shows that low physiological doses of 0.3-0.5 mg are equally or more effective for sleep onset, with fewer next-day side effects like grogginess and vivid dreams. Melatonin is particularly useful for jet lag, shift work, and delayed sleep phase. It is best taken 30-60 minutes before bedtime. Long-term, low-dose use also shows promise for antioxidant and longevity-related benefits, though chronic high-dose use is not recommended.
