Melatonin is a natural hormone in the brain that controls the body?s sleep and wake cycles. The body?s internal clock causes normal melatonin levels to rise in the evening, which brings on sleepiness. Melatonin supplements, like NiteThru, may help control irregularities that result in sleep problems.
