Natrol Melatonin 5 mg Melatonin is most effective in treating circadian sleep disorders. This type of sleep disturbance is associated with the time you are asleep or awake. The supplement needs to be used to make your brain believe in the night time and change your sleep time. Taking melatonin in the evening increases the tendency to fall asleep earlier. Melatonin is helpful in treating the following circadian sleep disorders: Jet lag. Research strongly suggests that melatonin is effective in reducing jet lag symptoms and improving sleep shortly after crossing multiple jet zones. Doctors recommend taking melatonin a few hours before your expected bedtime, starting at the start of your trip and continuing for several days after arrival. Doses of 0.5 to 5 mg can be effective in minimizing jet lag. Shift work. Melatonin helps improve the quality and duration of sleep for night shift workers. The supplement should be taken after the end of the shift, prior to the expected bedtime. Approximately 2-3 mg can be effective for shift workers. Delayed sleep phase. Delayed Sleep Disorder occurs when the timing of your circadian rhythms is delayed by two or more hours and you regularly go to bed late at night and wake up late in the morning. Taking melatonin can help you fall asleep earlier. Melatonin may also be helpful for other circadian sleep disorders, including late sleep phase disruption, free or irregular sleep and wakefulness.
