15. Melatonin for Sleep Disorders
Melatonin is a natural hormone that helps regulate the body’s sleep-wake cycle. Supplements are especially useful for people struggling with jet lag, shift work, or general sleep difficulties. Research consistently shows that melatonin can shorten the time it takes to fall asleep and improve overall sleep quality for many. For those seeking a gentle, non-habit-forming aid, melatonin is a well-studied and effective option. [Source: Mayo Clinic]
