Melatonin is a hormone secreted by the pineal gland in the body. It is generally secreted at night, where in most people, levels are the greatest during the normal hours of sleep. The level of melatonin in the body rapidly increases in the late evening, peaks after midnight and decreases toward the morning. It promotes sleep by fixing abnormalities in sleep-wake cycles and by releasing a direct soporific effect, namely when taken during the day. However, melatonin supplements should be taken in the evening. Studies also suggest that Melatonin affects the immune response to cancer, possibly by creating effects on cytokines, which inhibit the growth of tumors by killing infected cells.
