What is melatonin?
Melatonin is a hormone produced by the pineal gland, primarily in response to darkness. It plays a central role in regulating the body's sleep-wake cycle, often called the circadian rhythm.
Why supplement with melatonin?
Factors like screen exposure, irregular schedules, travel across time zones, and shift work can all disrupt natural melatonin production. Supplemental melatonin is commonly used to help signal to the body that it's time to wind down.
What does the research say?
Clinical guidelines from sleep medicine organizations, including those referenced by the European Sleep Research Society, discuss melatonin's role in circadian rhythm regulation and its use in insomnia management.

Safety considerations
Melatonin is generally well tolerated at typical supplement doses. It may affect blood sugar levels in some individuals with diabetes, and can interact with certain medications — consult a doctor if this applies to you.
