Blog 37 Side Effects Dosage and Health Benefits of Melatonin in Children and AdultsMelatonin

Melatonin, also known as the sleep hormone, is an important component of the body’s sleep-wake cycle. Its production increases with the arrival of evening darkness, promoting healthy sleep and aiding in the synchronization of the body’s circadian rhythm. Melatonin is produced naturally by the body, but it is also available in supplement forms such as in liquids or capsules for addressing sleep problems. Melatonin is one of the most commonly used supplements among both adults and children.

Melatonin Uses

It promotes consistent, quality sleep and facilitates the transition to sleep. Endogenous melatonin is melatonin produced within the body, but the hormone can also be produced externally. Exogenous melatonin is sold as a dietary supplement in the form of a pill, capsule, chewable, liquid, or patch.

Melatonin production and release from the pineal gland have a distinct daily (circadian) rhythm, with peak levels occurring at night. It is secreted into the bloodstream and cerebrospinal fluid after being produced and later it transmits signals to distant organs. Melatonin is carried by the bloodstream from the brain to every part of the body. Tissues that express proteins are called melatonin receptors and can detect the peak in circulating melatonin at night, signaling the body that it is time to sleep. Melatonin levels at night are at least ten times higher than during the day.

Natural sources of melatonin


A glass of warm milk is a well-known and popular sleep remedy. It contains the amino acid tryptophan, which increases melatonin and serotonin levels and makes it easier to fall asleep.

Tart cherries

Not only are tart cherries high in melatonin, but they are also high in anti-inflammatory compounds, which can help you stay healthy. It’s not just the cherries themselves that can put you to sleep. Tart cherry juice is also high in melatonin.

Goji Berry

Goji berries are high in naturally occurring melatonin. They are high in antioxidants, protein, and fibre. Goji berries may also help treat depression or anxious behavior, which can help you sleep by calming your mind and making it easier to fall asleep.


Bananas contain melatonin, tryptophan, vitamin B6, and magnesium, all of which are beneficial for serotonin production and sleep. They can help you sleep better and feel more alert during the day.

Melatonin Uses

1. Can help in boosting immunity

This natural hormone is also a powerful antioxidant, capable of protecting cells from oxidative damage without activating free radicals and assisting your body’s immune system. Melatonin production decreases with age, so taking a supplement or eating foods containing melatonin may help boost your immune system.

2. Improves Eye Health

Melatonin, which is high in antioxidants, may help prevent cell damage and promote eye health. Indeed, studies have revealed that melatonin’s cell-protective properties may aid in the treatment of glaucoma and age-related macular degeneration. The hormone may also help to prevent other age-related eye problems that can lead to vision loss.

3. Helps mitochondria function effectively

The mitochondria are the powerhouse of cells because they provide the energy that allows all of your cells to function optimally. Melatonin, which is also produced in mitochondria, allows them to function properly due to the antioxidant properties of the hormone.

Apart from these, melatonin also helps lower blood pressure, and improve thyroid function and heart health.

Melatonin deficiency

Melatonin production by the body is expected to be adequate for sleep. Unfortunately, modern lifestyle factors can contribute to melatonin deficiency. This can result in difficulty falling asleep and waking up in the morning, as well as fatigue throughout the day. The major factors that contribute to melatonin deficiency are listed below.

  • Jet Lag
  • Alcohol consumption
  • Shift duties
  • Caffeine
  • Blue light (from phone, TV, laptop)

  1. Sleep: Certain blood pressure medications cause sleep disruption (beta blocker-induced insomnia). Melatonin taken orally may help people who take beta-blockers sleep better.
  2. Endometriosis: Melatonin taken orally appears to reduce pain and the use of painkillers in adults with this condition. It also relieves pain during menstruation and intercourse.
  3. Insomnia: Short-term melatonin administration appears to reduce the time it takes for people with insomnia to fall asleep.
  4. Cancer: High doses of melatonin, administered by a healthcare provider along with chemotherapy or other cancer treatments, may reduce tumor size and improve survival rates in some cancer patients.
  1. Jet lag: Melatonin taken orally can improve some symptoms of jet lag, such as alertness, and reduce daytime sleepiness and tiredness. However, it may not help people suffering from jet lag in falling asleep faster.
  2. Migraine: Melatonin taken orally before bedtime can help prevent migraines in both adults and children.
  3. Thrombocytopenia: Melatonin taken orally can improve low blood platelet counts caused by cancer, cancer treatment, and other disorders.


Melatonin can be a safe short-term solution for sleep problems because it is well tolerated and does not cause the side effects that most prescription sleep medications do. According to research, it can help you fall asleep faster, sleep longer, and sleep better overall.

Melatonin dosage for adults

There is no official melatonin dosage recommendation for adults, but a range of 1 to 5 milligrams appears to be effective. Melatonin can be taken by adults a few hours before going to bed. Melatonin should not be used by pregnant or breastfeeding women without first consulting their doctor.

Melatonin dosage for children
The effective dosage for children is determined by the type of sleep disorder they are experiencing. Typical dosages for treating insomnia in children begin at 1 to 2 milligrams and gradually increase with age. When children take melatonin, the side effects are usually mild and may include:

  • Irritation
  • More than usual bedwetting
  • Dizziness
  • Drowsiness
  • Headaches

Melatonin may be prescribed by a doctor for children who have sleep disorders such as insomnia, autism spectrum disorder, or attention deficit hyperactivity disorder. If your child is having difficulty sleeping, consult your doctor before administering melatonin.

Melatonin Side effects in Children and adults

If you take an unusually large dose of melatonin, you may experience severe drowsiness. This supplement is commonly used to induce sleep and may impair your ability to stay alert or focused during your daily activities. Excessive drowsiness may cause you to sleep for several hours.

An overdose of this supplement may cause headaches. This side effect may impair your ability to focus on daily tasks and may aggravate feelings of drowsiness or fatigue. If you experience sudden or severe headache pain after taking melatonin, contact your physician.
