Circadin (Melatonin)



Melatonin is a natural hormone produced by the body. Synthetic melatonin is used as a medicine to help the body adjust the internal clock. It is used by people who suffer from jet lag, to adjust the sleep pattern as a result of work schedule changes, and to help blind people establish a day and night cycle.

Melatonin Details

Melatonin is a natural hormone produced by the pineal gland in the brain. It primarily regulates sleepiness and wakefulness. Normally, the body produces more melatonin at night, when it's dark. Melatonin levels go down as the sun rises. For some people, it does not always happen. That’s why melatonin supplements are formulated in chewable, pills, and liquid forms.


How Melatonin Works

The main purpose of melatonin, both natural and synthetic, is to regulate the cycles of night and day. During the night, when it is dark, the body produces more melatonin to create a signal that the body needs to sleep. Conversely, the presence of light minimizes melatonin production, a signal for us to wake up. Hence, individuals with low levels of melatonin have difficulty in falling and sustaining sleep. So melatonin supplements help a person to fall asleep easier.  

What are Melatonin’s Benefits?

Basically, people can make use of melatonin when they find it hard to fall and stay asleep. Aside from that, it is also used to treat other sleeping problems. One of them is the condition called delayed sleep phase disorder. Furthermore, those who encounter work-related disruption of normal sleep schedules, or more commonly known as sleep work disorder, can also benefit from this medicine.  

How to Use Melatonin

Before taking melatonin, take note that it has a short half-life. This refers to the fact that Melatonin stays in the body for about 20 minutes only. Also, there have been a lot of melatonin supplements released on the pharmaceutical market up to date so it is recommended to choose the one made with high quality.

When it is your first time using a melatonin supplement, start with the lowest dose available. Do not cut the pill since it is specially coated to be released slowly. Hence, cutting the pill would destroy the coating and long-term potency.   Take a melatonin pill at least one hour before going to sleep. Time-released pills of melatonin can last up to 4 hours so in case you are unable to sleep within this time frame, a second dose can be taken.   If you wake up at night that takes less than an hour, take a sublingual melatonin pill, a variant that is formulated to be dissolved under the tongue.

The melatonin is thereby released into your blood bypassing digestive metabolism.
  If you wake up at night that lasts longer than an hour, take instead a sublingual and time-released melatonin tablet. Take the sublingual pill after the time-released tablet.
