What You'll Learn
Melatonin dosage for adults and children
Melatonin is a sleep hormone that helps prepare the body for sleep. It is not a sedative and is not habit-forming. It is available over the counter in a range of doses, from 1 milligram (mg) to 10 mg and higher. However, there is no universally agreed-upon maximum dose. Melatonin is not recommended for long-term sleep issues and should be used as a short-term solution.
Melatonin dosage for adults
The most common melatonin dosage for adults is 3 mg to 5 mg. Some sources suggest that adults usually take up to 8 mg daily. However, it is important to start with a low dose and increase gradually if needed to reduce the risk of side effects. Adults can start with 1 mg and increase by 1 mg each week until they achieve the desired outcome. It is recommended to take melatonin one to two hours before bedtime.
Melatonin dosage for children
Melatonin may be safe for children, but it has not been widely studied. It is recommended to consult a doctor or pediatrician before giving melatonin to children, especially if they have underlying medical conditions. Children typically take 1 mg to 2 mg of melatonin, but may need up to 3 mg daily. Children weighing less than 88 pounds should not exceed 3 mg per dose, while those weighing more than 88 pounds can take up to 5 mg. Similar to adults, children should start with a low dose of 0.2 mg to 0.5 mg and increase gradually if needed. Melatonin should not be given to children under the age of 2 or 3 years unless recommended by a doctor.

Side effects of melatonin
Melatonin is a neurohormone produced by the pineal gland in the brain, mainly at night. It is sometimes called the "hormone of sleep" or "hormone of darkness" as it prepares your body for sleep. Melatonin supplements are widely used as a sleep aid. They help you fall asleep, improve sleep quality, and increase sleep duration. However, they do not appear to be as effective as many other sleep medications.
While melatonin supplements are generally considered safe in the short term, even at very high doses, there are some reported side effects. Firstly, melatonin supplements should be taken in the evening. When taken at other times of the day, they may cause undesirable sleepiness. Sleepiness is technically not a side effect but rather its intended function. However, sleepiness can carry on into the following day. This is the most common side effect of melatonin. To prevent daytime sleepiness, make sure you only take melatonin in the evening or in the hours before bed.
Dizziness is another common side effect of melatonin. The exact reason is not fully known, but it may be related to blood pressure changes. Some studies suggest that melatonin may lower blood pressure at night. People who take melatonin, especially those already on high blood pressure medication, may feel light-headed if their blood pressure gets too low. Headaches are also a common side effect of melatonin. They can be triggered by a high dose or sensitivity to melatonin.
Other side effects include nausea and agitation. However, these were equally common in the treatment and placebo groups and couldn't be attributed to melatonin. Melatonin supplements can also increase the time spent in rapid eye movement (REM) sleep, which is associated with more vivid dreams or nightmares. The risk of side effects increases when supplementation is above the recommended dose; however, they can also happen even at standard doses.
Serious side effects are rare and happen to less than 1 in 1,000 people. In rare cases, it is possible to have a serious allergic reaction (anaphylaxis) to melatonin. Symptoms include swollen lips, mouth, throat, or tongue, struggling to breathe, and a tight throat. Melatonin is not recommended for children as it is not known to be completely safe for them.

Safety precautions and warnings
Melatonin is a naturally occurring hormone that helps regulate sleep-wake cycles. While it can be an effective short-term sleep aid for some people, it's important to be aware of certain safety precautions and warnings before taking it.
Firstly, it is recommended to try improving your sleep hygiene practices before turning to melatonin supplements. This includes maintaining a consistent bedtime and wake-up time, limiting screen time before bed, avoiding caffeine and alcohol later in the day, and creating a comfortable sleep environment by keeping the room cool, dark, and quiet.
Secondly, melatonin supplements should be used with caution and only after consulting a healthcare professional, especially if you are taking other medications or have an underlying health condition. Pregnant or breastfeeding individuals, as well as those with a history of seizures, autoimmune disorders, or depression, should not take melatonin without medical advice.
Additionally, melatonin supplements are not regulated by the Food and Drug Administration (FDA), and the dose can vary between products. It is crucial to follow the recommended dosage instructions and be aware of potential side effects, which may include drowsiness during the day, headaches, vivid dreams, nightmares, dizziness, stomach aches, dry mouth, skin irritation, and changes in appetite.
Furthermore, while melatonin can be beneficial for jet lag, it is generally recommended for short-term use only. If you are considering long-term melatonin use, it is advised to consult a specialist. For jet lag specifically, melatonin should not be taken for more than 5 days, and it is important to follow the recommended timing and dosage instructions.
Lastly, it is important to note that melatonin may not be effective for everyone, and there is limited research on its long-term effects. It is always advisable to speak to your healthcare provider before starting any new supplement, including melatonin, to ensure it is safe and appropriate for your individual needs and circumstances.

Natural ways to increase melatonin
Melatonin supplements are increasing in popularity, but there are also natural ways to increase your melatonin levels. Melatonin is a hormone that plays a major role in your sleep-wake cycle, or what’s scientifically referred to as your circadian rhythm. While there’s always some level of melatonin in your body, the amount changes throughout the day. Typically, your melatonin levels go up when the sun goes down, signalling to your body that it’s time to go to bed. Your levels peak between 2 a.m. and 4 a.m. and start to decrease again throughout the early morning hours. Melatonin levels are lowest when you wake up.
- Get sunlight in the morning: Getting exposure to sunlight early in the morning can make you more alert during the day and trigger your body to produce nighttime melatonin sooner, so you feel sleepy earlier at night.
- Avoid screens before bed: The blue and green light from smartphones, computers, and tablets can neutralize melatonin’s effects. If you watch television, be sure to be at least six feet away from the screen. Turn off bright overhead lights too.
- Eat melatonin-rich foods: Foods such as eggs, mushrooms, cherries, apples, bananas, peaches, chicken, turkey, oatmeal, and warm milk may increase the amount of the hormone in your body.
- Avoid caffeine and alcohol close to bedtime: Both of these substances can cause low melatonin levels.
- Try essential oils: Certain oils such as lavender or chamomile can help your child relax, causing their body to raise its melatonin levels in response.

Melatonin supplements are growing in popularity, with 3 million Americans using them in 2012, according to a nationwide survey by the CDC.
While melatonin can be beneficial for occasional sleeplessness, it should be used with caution. It may interact with certain medications, including antidepressants, antianxiety medications, diabetes medications, narcotics, blood pressure medication, and asthma medication. Additionally, pregnant or nursing individuals, those trying to conceive, or those with chronic medical conditions, should consult a physician before taking melatonin. Melatonin can cause grogginess, so it is important not to drive or operate machinery within eight hours of taking it.
For children and teens, melatonin supplements should be approached with caution and under the guidance of a healthcare provider. While melatonin can be beneficial for some children with sleep issues, it is important to first establish a consistent sleep routine. The recommended starting dosage for children is 0.25-0.5 mg, with a maximum dose of 3 mg for those weighing less than 88 pounds and 5 mg for those weighing more. Children under 2 years old should not take melatonin, and parents should always be in charge of administering the supplement.
