What it does: Melatonin helps regulate the body’s circadian rhythm and signals the onset of sleep, making it a key regulator of the daily sleep-wake cycle.
How it is used: Melatonin supplements are commonly used to support falling asleep, adjust to changes in time zones (jet lag), or promote sleep in shift workers or those with irregular schedules.
Natural sources and supplement forms: Small amounts of melatonin are found in foods like tart cherries, grapes, and walnuts, but supplement forms typically contain synthetic melatonin in tablets, capsules, or gummies.
Why it appears in supplement formulas: Melatonin is valued for its ability to help encourage a regular sleep schedule, making it a popular choice for those experiencing temporary or occasional sleep disruptions.
What to know before use: Melatonin may cause drowsiness and can interact with sedatives or certain medications; consult a healthcare professional before use, especially if you have a medical condition or take prescription drugs.

Melatonin is released by your brain in response to darkness and helps tell your body when it's time to get ready for sleep—not by sedating you, but by nudging your natural sleep-wake cycle. While your body makes it every night, small amounts are also found in foods like tart cherries and walnuts, although supplement amounts are typically higher.
