What is Melatonin?

Melatonin is a natural compound found in plants and animals, first discovered in 1958. It is primarily known as a hormone released by the pineal gland in the brain at night and has long been associated with control of the sleep-wake cycle. Melatonin is involved in synchronizing circadian rhythms, including the sleep-wake cycle and blood pressure regulation. It is also responsible for seasonal rhythmicity including reproduction, fattening, and hibernation.

As a dietary supplement, Melatonin is used in the treatment of sleep and circadian rhythm disorders.

What is the Mechanism of Action of Melatonin?

Intake of Melatonin increases levels of gamma-Aminobutyric acid and serotonin in the midbrain and hypothalamus as melatonin is responsible for regulating the pyridoxal kinase and higher Melatonin levels influence the synthesis of these compounds. The drug inhibits the secretion of gonadotropins and other pituitary gland hormones (corticotropin, thyroid-stimulating hormone, and somatotropin). It normalizes daily changes in body activity and temperature, improves brain activity, and reduces irritability.

What are the Benefits and Effects of Melatonin?

Melatonin has a positive effect on night sleep. It helps fall asleep, reduces nighttime awakenings, and facilitates morning awakening.

The drug has also been proven effective in adapting to the rapid change of time zones while traveling. Melatonin can be used to reduce stress and weather sensitivity and stabilize the neuroendocrine system. Melatonin has immunomodulating and antioxidant properties. The drug is non-addictive. It has been shown that the natural production of melatonin declines with age, so it is better to use melatonin at an older age.

What is Melatonin Used For?

Melatonin is used in the prevention and treatment of:

  • Desynchronosis (alterations to the body’s circadian rhythms caused by rapid long-distance trans-meridian (east-west or west-east) travel or working shifts and jet lag);
  • Weather sensitivity;
  • Fatigue and sleep disorders;
  • Depression.

Melatonin also helps blind people establish a day and night cycle.
