What is Circadin?


Melatonin is a hormone produced by the pineal gland. Melatonin is used by the body to regulate sleep and wakefulness. The body will normally produce more melatonin at night, with the level inside of the body being changed as the sun sets and when the sun rises. Circadin is a melatonin supplement in a synthetic form that is used as a short term treatment of insomnia in people aged 55 and over.

How does Circadin (Melatonin) work?

Melatonin’s main function is to regulate night and day cycles. The onset of darkness makes the body produce more melatonin, a signal for the body to get ready to sleep. Natural light decreases the production of melatonin which is a signal for the body to get ready to wake up. If someone has low levels of melatonin then they will find it very difficult to fall asleep. Giving them a Circadin supplement will help them to get a good, natural night's sleep.

What are the benefits of taking Circadin (Melatonin)?

People use Circadin when they have trouble falling and staying asleep. Circadin can also be taken for other sleep problems, especially insomnia for those ages 55 and over. Melatonin provides great benefits to people whose jobs disrupt their normal sleep schedules, a condition known as sleep work disorder.

How do I use Circadin (Melatonin)?

Circadin Tablets / Melatonin Tablets

It is important to know that melatonin has a very short half-life. In most cases, melatonin will only stay in your system for around 20 minutes. This is why it is very important that you find a supplement, such as Circadin, which is high quality.

What is the proper dosage of Circadin (Melatonin)?

Circadin 2mg

When you are using a melatonin supplement for the first time, it may be beneficial to find the lowest dose available. You should also make sure not to cut the pill as it is coated for slow release. If you cut the pill you will find that the results you experience will be lessened.

You should aim to take a time-released Circadin pill one to three hours before your usual sleep time. Time-released melatonin lasts for three to four hours, so if you cannot go to sleep within that time frame, you may need to take another pill.
