All About Melatonin

All About Melatonin - Source Biology


The pineal gland inside the brain produces melatonin, a hormone that regulates sleep and wakefulness. It is in charge of maintaining a healthy sleep cycle in the body.

The production and release of melatonin in the brain is connected to time of day, increasing when it’s dark and decreasing when it’s light. Melatonin production declines with age.

Generally not as abundant in foods, melatonin is also available as a supplement, typically as an oral tablet or capsule. Most melatonin supplements are made in a lab.

People commonly use melatonin for sleep disorders, such as insomnia and jet lag.

Health benefits of Melatonin

1. Enhances the quality of one’s sleep

This hormone is commonly referred to as the sleep hormone and for good reason. It helps achieve sleep goals in various situations. Some of these include re-regulating delayed sleep patterns – where one’s sleep cycle is delayed. Research shows that melatonin reduces the length of time needed to fall asleep and advances the start of sleep in adults and children with this condition. Further research suggests that melatonin helps fight insomnia, reducing the time it takes to fall asleep. Evidence also shows that melatonin can improve jet lag symptoms, such as alertness and daytime sleepiness.

2. Seasonal depression symptoms reduced.

An estimated 10% of people worldwide suffer from the seasonal affective disorder, better known as seasonal depression. These seasonal variations and their effect on your circadian are linked to this kind of depression, which is most common in the late fall and early spring. Seasonal depression has been linked to circadian rhythm variations, and low melatonin doses have been found to help alleviate symptoms.

3. Human Growth Hormone Levels May Be Boosted

Hormones like human growth hormones (HGH) are critical for the growth and regeneration of cells in the body. They have also been connected to increased strength and muscle mass in those with higher levels. While good sleep alone may benefit HGH levels, further research has shown that a melatonin supplement can directly enhance HGH production.

4. It can be good for the eyes.

Antioxidants found in high concentrations of melatonin can help protect cells from harm and maintain the health of your eyes. Melatonin has been shown to help treat illnesses such as glaucoma and age-related vision problems. The retina was protected, delayed age-related degeneration, and preserved visual acuity by taking 3 milligrams of melatonin over 6–24 months. Retinopathy, an eye illness that damages the retinal and can lead to blindness, was less common and less severe when taken with melatonin.


Melatonin has been explored for its possible significance in other illnesses, such as stress, depression, migraines, and cancer. These conditions may benefit from melatonin, but more research is required to identify the possible benefits and hazards.


Taking melatonin can be very advantageous. It can help you get to sleep quicker and remain asleep longer. It can help alleviate jet lag and induce sleep. Melatonin is also a potent antioxidant. When using melatonin, there are several to keep in mind: The most effective time frame is to take it 30 to 60 minutes before sleeping. Starting with a modest dose and gradually increasing it is also critical. Side symptoms like headaches, nausea, or dizziness have been reported. If you see any adverse effects, quit taking melatonin and see your doctor.
