Melatonin is a popular sleep aid that is available over the counter and is also prescribed by doctors for short-term sleep problems. While it can be effective in helping people fall asleep, it is important to take the correct dose, as taking too much melatonin can lead to unwanted side effects. The typical dose ranges from 1 to 5 milligrams, but smaller doses are often more effective and have fewer side effects. Experts recommend starting with a low dose of 0.5 to 1 milligram, taken 30 to 60 minutes before bedtime, and gradually increasing the dose if needed. Taking more than the recommended amount of melatonin can be dangerous and may cause side effects such as headaches, dizziness, daytime sleepiness, stomach aches, and dry mouth. It is important to consult a doctor before taking melatonin, especially for children, as the dose may depend on factors such as age and weight.

Melatonin is a hormone that your body naturally produces to help regulate your sleep-wake cycle
The pineal gland produces melatonin, which is also available as a synthetic supplement. Synthetic melatonin is widely used as a sleep aid, with sales in the US more than doubling between 2017 and 2020, rising to $821 million. However, it's important to note that melatonin is not a cure-all for sleep difficulties, and you should consult your doctor before taking it.
The typical dose of melatonin for sleep ranges from 1 mg to 5 mg, with most people rarely needing more than 5 mg. Experts recommend starting with a lower dose of around 0.5 to 1 mg, taken 30 to 60 minutes before bedtime. This allows you to gauge how your body responds and helps reduce the risk of potential side effects such as grogginess or vivid dreams. If needed, the dose can be gradually increased, but it's important not to exceed the maximum recommended dose of 10 mg.
While melatonin is generally safe, taking too much can lead to unwanted side effects. Hypermelatoninemia is a condition where there is too much melatonin in your blood. This can increase the risk of health conditions such as hypogonadotropic hypogonadism and polycystic ovary syndrome. Additionally, taking more melatonin than you need can lead to unwanted side effects. It's important to remember that the goal is to match what your body naturally produces, and you may be able to boost your melatonin levels naturally through good sleep habits, such as dimming the lights and turning off screens a few hours before bed.

Melatonin supplements are popular, but you may be taking more than you need
Melatonin supplements are widely used to aid sleep, with sales in the US more than doubling between 2017 and 2020, reaching $821 million. However, it is important to be aware that you may be taking more melatonin than you need, which can lead to unwanted side effects.
Melatonin is a hormone produced naturally by the brain's pineal gland. It is sometimes known as the "hormone of darkness" because the body increases its production of melatonin after the sun goes down, causing sleepiness and signalling that it is time for bed. Melatonin's main function is to help regulate the sleep-wake cycle.
While melatonin supplements can be effective in aiding sleep, it is recommended that you first try to boost your body's natural melatonin levels through good sleep habits. Artificial light at night can suppress your body's production of melatonin, so it is advisable to dim the lights and turn off electronic devices 2 to 3 hours before bed. Exposure to daylight during the morning and afternoon can also help to programme your body to produce melatonin at the right time of day.
If you are considering taking melatonin supplements, it is important to start with a low dose to gauge how your body responds and reduce the risk of potential side effects. Experts recommend starting with a dose of between 0.5 and 1 milligram, taken 30 to 60 minutes before bedtime. It is not necessary to take a large dose of melatonin, and smaller doses may actually deliver better results and have fewer side effects. The maximum recommended dose is 10 milligrams.
If you are experiencing difficulty falling asleep, you should consider speaking to your doctor or a healthcare professional before taking melatonin supplements.

Small doses of melatonin may be more effective and have fewer side effects
Melatonin is a hormone that helps regulate the body's sleep-wake cycle, also known as the circadian rhythm. It is typically produced by the brain's pineal gland when it gets dark, causing sleepiness and signalling that it is time for bed.
While melatonin is available as a supplement and is one of the most widely used over-the-counter sleep aids, it is recommended that you first try to boost your melatonin levels naturally through good sleep habits. For example, you could limit your exposure to artificial light at night, as this can suppress your body's production of melatonin. Sleep experts recommend dimming the lights and turning off screens 2 to 3 hours before bed.
If you do decide to take melatonin supplements, it is important to start with a low dose and gradually increase if necessary. Most adults are advised to start with 0.5 to 1 milligram of melatonin, taken 30 to 60 minutes before bedtime. This allows you to gauge how your body responds and helps to reduce the risk of potential side effects, such as grogginess or vivid dreams. It is worth noting that doses of 3 mg and higher are more than your body's natural production of the hormone.
Research has shown that smaller doses of melatonin may be more effective and have fewer side effects than larger dosages. This is because the goal is to match what your body naturally produces, and taking too much can interfere with your body's natural production of melatonin. In fact, melatonin is most effective when taken at slightly different times each night, depending on the purpose. For example, if your teen usually goes to bed at 2 a.m. due to delayed sleep phase syndrome, you should give them a low dose of melatonin at 11 p.m. and gradually adjust as their sleep cycle moves earlier.
It is important to consult a healthcare provider before starting melatonin, especially if you have a medical condition or take medications that affect hormone levels or sleep. While melatonin is typically safe and well-tolerated at low doses, there is a lack of safety data on long-term use of high doses.

Melatonin should not be taken with alcohol or caffeine
Melatonin supplements are generally considered safe for adults for short-term use. However, it is important to avoid mixing them with alcohol and caffeine. Alcohol is known to reduce the amount of melatonin your body can create, which can interrupt your sleep cycle. Consuming alcohol with melatonin can also lead to increased drowsiness, dizziness, and anxiety, and negatively impact your liver and breathing.
Alcohol is a sedative that can make you feel sleepy, but when combined with melatonin supplements, it may cause excessive tiredness and make it harder to wake up. In rare cases, individuals may experience more severe side effects, such as rapid heartbeat, feelings of weakness, mild shaking, flushed skin, sweating, dizziness, headache, disorientation, and hallucinations.
The combination of melatonin and alcohol can also affect your liver's ability to produce certain enzymes. Therefore, it is recommended to take melatonin supplements with no alcohol in your system or wait for a long time after consuming alcohol before taking melatonin.
Caffeine consumption can also alter blood melatonin levels. While tobacco smoking reduces melatonin levels, caffeine increases them. This can affect the dosing of melatonin supplements. Therefore, it is important to inform your doctor about your caffeine consumption if you are taking melatonin supplements.
Additionally, it is recommended to limit exposure to blue light from electronic devices and bright lights before bedtime when taking melatonin. Blue light can reduce the production of melatonin and make the supplement less effective.

Melatonin is not recommended for pregnant or breastfeeding people
Melatonin is a hormone that helps regulate the sleep-wake cycle, also known as the circadian rhythm. It is typically taken to aid sleep and is available as a supplement sold over the counter. However, it is important to note that melatonin is not recommended for pregnant or breastfeeding individuals due to insufficient clinical research and potential risks.
Firstly, there is a scarcity of clinical trials investigating the safety and efficacy of melatonin for sleep disorders during pregnancy and breastfeeding. The existing research primarily consists of animal studies, which have raised concerns about potential adverse effects, including decreased birth weight, altered circadian rhythm development, and mortality. While these specific concerns have not been identified in the limited human clinical studies, the lack of comprehensive research means that no definitive conclusions can be drawn about the safety of melatonin for pregnant and breastfeeding individuals.
Secondly, while melatonin is naturally present in breast milk, the impact of taking manufactured melatonin supplements during breastfeeding is not well understood. Melatonin levels in breast milk follow a circadian rhythm, with higher levels at night to promote sleepiness in infants. However, when taking supplements, it is unclear how much melatonin passes into the breast milk, and prolonged use may lead to increased sleepiness in the infant. One reported case described an infant experiencing a bleeding problem while being breastfed by a woman taking a melatonin and valerian supplement, although this has not been replicated in other studies.
Additionally, it is important to note that melatonin supplements are not well-regulated for use during pregnancy, and their impact on fertility, miscarriage risk, and fetal development is not comprehensively studied. Therefore, it is generally recommended to consult a healthcare provider before taking any supplements during pregnancy or breastfeeding to assess the benefits and risks based on individual circumstances.
In summary, melatonin is not recommended for pregnant or breastfeeding people due to the limited clinical research and the potential risks suggested by existing studies. While no major safety concerns have been reported in human clinical studies, the lack of comprehensive research leaves uncertainties about the safety and efficacy of melatonin for this specific population. Therefore, individuals who are pregnant or breastfeeding should exercise caution and consult their healthcare provider before taking melatonin supplements.
