Description
Melatonin is a hormone naturally produced by the pineal gland in response to the body’s light-dark cycle. It helps regulate circadian rhythms and signals the body that nighttime is approaching. Melatonin supplements provide an additional source of this hormone and are commonly used for jet lag and certain circadian rhythm sleep disorders. Effectiveness varies according to timing, dosage, and the underlying sleep concern. Possible adverse effects include daytime drowsiness, dizziness, and headache, and the supplement may interact with certain medications.
