What You'll Learn
Melatonin for insomnia
Melatonin is a natural hormone that plays a key role in regulating sleep. Our bodies typically produce enough melatonin for sleep, but certain factors, such as insomnia, jet lag, or irregular work schedules, can disrupt this process. In such cases, melatonin supplements may be beneficial.
Melatonin supplements are widely promoted for sleep disorders, including insomnia. They are available in the form of tablets or capsules and are generally considered safe for short-term use by most adults. The recommended dosage is typically between 1 to 3 milligrams, taken two hours before bedtime. It is important to follow the instructions provided with the medication and not to exceed the recommended dosage. Melatonin supplements should only be taken for a short period, usually one to four weeks, and if sleep problems persist, it is advisable to consult a healthcare professional.
The use of melatonin supplements has been found to help people with insomnia fall asleep slightly faster, although the reduction in sleep onset time may only be by a few minutes. Additionally, melatonin may offer greater benefits for those with delayed sleep phase syndrome, characterized by falling asleep and waking up very late. Melatonin can also be helpful for individuals who need to adjust their sleep schedule, such as night owls who need to adapt to earlier bedtimes and wake-up times for work or school.
It is important to note that melatonin supplements may not be suitable for everyone. Pregnant or breastfeeding women, individuals with autoimmune disorders, seizure disorders, or depression should refrain from taking melatonin. Furthermore, those with diabetes or high blood pressure should consult their healthcare provider before taking melatonin, as it may affect blood sugar and blood pressure levels. Melatonin may also cause side effects such as headaches, sleepiness, dizziness, and nausea. Therefore, it is important to be cautious and informed before taking any supplements.

Melatonin for jet lag
Melatonin is a supplement that can help regulate your sleep cycle. It is often used to treat insomnia and jet lag. Melatonin is generally safe for most adults when taken short-term, and it has been used safely for up to two years. However, it is important to note that melatonin may cause side effects such as headache, sleepiness, dizziness, and nausea. It is recommended to consult a healthcare provider before taking melatonin, especially for those with diabetes or high blood pressure.
When using melatonin for jet lag, it is typically taken by mouth with a glass of water. The usual dose for jet lag is one 3mg standard tablet, taken once a day for up to five days. It is recommended to take the first dose at your normal bedtime when you arrive at your destination, preferably not before 8 pm or after 4 am. If needed, you can increase the dose to up to two 3mg tablets (6mg) per day. It is important not to exceed 16 treatment courses in a year.
To optimize the effects of melatonin for jet lag, it is advised to start taking the supplement a few days before your trip. Additionally, creating optimal conditions for sleep is crucial. This includes keeping the lights low before bed and minimizing exposure to blue and green light from electronic devices, as these can neutralize melatonin's effects. Getting outside for natural light exposure during the day can also help adjust your body to the new time zone.
It is important to follow the instructions provided with your medication and consult a healthcare professional if you have any concerns or questions. Melatonin is not suitable for everyone, and it is recommended to discontinue use if it does not provide any benefit after a week or two. Additionally, melatonin should not be taken if you are pregnant or breastfeeding or have certain medical conditions, such as an autoimmune disorder, seizure disorder, or depression.

Who shouldn't take melatonin
Melatonin is a supplement that helps regulate sleep cycles and is often used to treat insomnia, jet lag, and delayed sleep phase syndrome. While melatonin is likely safe for most adults when used short-term, there are several groups of people who should not take melatonin:
Pregnant or Breastfeeding Women
It is recommended that pregnant or breastfeeding women do not take melatonin as it may have effects similar to birth control, making it more difficult to become pregnant. Additionally, there is insufficient information to determine whether melatonin is safe for use during pregnancy or breastfeeding.
Individuals with Certain Medical Conditions
People with specific medical conditions, such as autoimmune disorders, seizure disorders, or depression, should avoid taking melatonin. It can also negatively interact with certain medications, such as hypertension drugs, and raise blood sugar and blood pressure levels. If you have diabetes or high blood pressure, it is advisable to consult a healthcare provider before taking melatonin.
Individuals with Mood Disorders
Melatonin may not be suitable for individuals experiencing mood disorders, such as anxiety, nervousness, confusion, hallucinations, irritability, or feelings of depression. While melatonin is not used for mood management, taking it daily could indirectly impact an individual's mood by affecting their sleep quality.
Individuals Undergoing Surgery
The effects of melatonin on adults undergoing surgery are unclear, and it may cause confusion and agitation after surgery. Therefore, individuals preparing for surgery should consult their healthcare provider before taking melatonin.
Individuals on Specific Medications
Melatonin may interact with specific medications and cause adverse effects. For example, it does not reduce withdrawal symptoms in individuals with insomnia who have stopped taking benzodiazepines. Additionally, individuals taking beta-blocker drugs should consult a healthcare provider before taking melatonin.

Melatonin and pregnancy
Melatonin is a hormone that is normally produced by the body and is involved in regulating normal sleep-wake cycles. It is also sold over the counter as a dietary supplement to promote sleep. Melatonin levels naturally increase with each trimester during pregnancy.
While melatonin is likely safe for most adults when used short-term, there is insufficient evidence to confirm that taking melatonin supplements is safe during pregnancy. The placenta makes melatonin, so it is always present in the body during pregnancy. Melatonin can cross the placenta and enter the fetus's bloodstream, and even at low doses, it could affect the baby's hormonal signal development. Therefore, it is generally recommended to avoid taking melatonin during pregnancy as a precaution.
However, there is ongoing research on the use of melatonin during pregnancy, and some healthcare professionals may recommend it in certain cases. For example, some professionals suggest melatonin supplements for older women trying to become pregnant, pregnant women with preeclampsia, or women with endometriosis. Promising animal studies indicate that melatonin supplementation during pregnancy may reduce the risk of preeclampsia, preterm birth, and intrauterine growth restriction (IUGR). Melatonin may also have beneficial effects on fertilization rates and embryo quality.
If you are pregnant and experiencing insomnia, it is recommended to consult with your doctor before trying melatonin supplementation. They can help you weigh the potential benefits against the risks and consider your health history, medications, and other supplements. In the meantime, cognitive-behavioral therapy for insomnia (CBT-I) and improved sleep hygiene may help improve your sleep.

Melatonin side effects
Melatonin is likely safe for most adults when used short-term. However, it can cause some side effects, including headache, sleepiness, dizziness, and nausea. It is recommended that you do not drive or operate machinery for 4-5 hours after taking melatonin due to its effects on reaction time and judgment. Alcohol consumption can increase the risk of these side effects.
Some people may experience mood and behavior changes, including anxiety, nervousness, confusion, hallucinations, irritability, hostility, and thoughts of suicide or self-harm. If you experience any of these side effects, it is important to consult your healthcare provider.
Serious side effects are rare, occurring in less than 1 in 1,000 people. However, it is possible to have a serious allergic reaction (anaphylaxis) to melatonin, with symptoms such as swelling of the lips, mouth, throat, or tongue, breathing difficulties, a tight throat, or skin, tongue, or lips turning blue, grey, or pale. If you experience any of these symptoms, seek immediate medical attention.
Additionally, melatonin is not recommended for pregnant or breastfeeding women, and those with certain medical conditions, such as autoimmune disorders, seizure disorders, or depression, should consult their healthcare provider before taking melatonin.
