Sleep disturbances during pregnancy are common, and many women seek ways to manage them. Melatonin is a naturally occurring hormone that regulates sleep-wake cycles and is sold over the counter as a dietary supplement to aid sleep. While melatonin is considered natural, the amount delivered by over-the-counter preparations often exceeds the body's natural production, and little is known about its impact on the developing fetus. Some studies suggest that melatonin may play a role in reducing the risk of certain pregnancy complications and improving fertilization rates, while others indicate that it may affect neurological development and the baby's circadian rhythm. As such, it is recommended that pregnant women experiencing sleep problems use medications with a better-characterized reproductive safety profile. However, some healthcare providers may suggest melatonin for sleep during pregnancy when used under medical supervision and with correct dosage.

Melatonin is a hormone that regulates sleep-wake cycles and is available as a supplement
Melatonin is a hormone that regulates sleep-wake cycles. It is produced by the brain and is available as a supplement to treat sleep problems. Melatonin is also sold over the counter as a dietary supplement. The dose used in most melatonin supplements (1 to 3 mg) can elevate blood melatonin levels up to 20 times the normal amount.
Pregnant women often experience sleep disorders, with up to 80% experiencing insomnia by the third trimester. Many women seek ways to manage their sleep problems and may consider melatonin supplements as a potential remedy. However, it is important to note that the amount of melatonin delivered by over-the-counter preparations typically exceeds the amount naturally produced by the body. As with most supplements, there is limited research on the impact of high levels of melatonin on the developing fetus.
Some studies suggest that melatonin plays a role in a healthy pregnancy. Research in animals has shown that melatonin can reduce oxidative stress and may decrease the risk of pre-eclampsia, preterm birth, and intrauterine growth retardation (IUGR). Additionally, melatonin may increase fertilization rates and embryo quality. In humans, melatonin levels are lower in pregnant women with severe preeclampsia, a condition characterized by high blood pressure and protein in the urine that can lead to seizures, organ damage, and birth complications.
While melatonin may have potential benefits during pregnancy, there is ongoing research into its safety. Melatonin levels naturally rise during pregnancy, and supplemental melatonin could negatively impact the baby and their sleep patterns after birth. Currently, there is a lack of randomized controlled trials examining the efficacy and safety of melatonin for sleep disorders during pregnancy. Although clinical trials using melatonin during pregnancy for other conditions have not shown major safety concerns, more research is needed to fully understand the impact of supplemental melatonin on the developing fetus and pregnancy outcomes.
Pregnant women experiencing sleep problems should consult their healthcare providers before taking melatonin or any other sleep aids. While some doctors may advise against it, others may recommend it under medical supervision, emphasizing the importance of correct dosage. Breastfeeding women can take melatonin if their baby is healthy, although it is unknown how much passes into breast milk.

Sleep disturbances are common during pregnancy, affecting 46-78% of women
The dose used in most melatonin preparations is higher than what the body normally produces. A typical dose of melatonin (1 to 3 mg) elevates blood melatonin levels up to 20 times the normal levels. Melatonin levels tend to naturally increase with each trimester during pregnancy. Research suggests that supplemental melatonin is safe during pregnancy when used under medical supervision. Using the correct dosage is crucial for the safety and development of the pregnancy. If you are pregnant, you might notice you have more trouble sleeping than usual.
There is a lack of randomised, controlled trials examining the efficacy and safety of melatonin as a treatment for sleep disorders during pregnancy. However, clinical trials that have used exogenous melatonin during pregnancy for other clinical conditions have not suggested major safety concerns or adverse events. Evidence from clinical studies to date suggests that melatonin use during pregnancy is probably safe in humans. Melatonin likely helps train a circadian rhythm in a fetus, which could potentially impact sleeping patterns after birth. Melatonin may also affect neurological development in a fetus, reducing the likelihood of problems such as brain lesions.
In animal studies, it has been shown that melatonin supplementation decreases the risk of pre-eclampsia, preterm birth, and intrauterine growth retardation (IUGR). Studies of melatonin in humans with IUGR and pre-eclampsia are now in their earliest phases. Preliminary studies also suggest that melatonin supplementation may have a beneficial effect on fertilization rates and embryo quality, likely due to a reduction in oxidative damage.

Melatonin levels increase during pregnancy, peaking in the third trimester
Sleep disruption is a common issue during pregnancy, with as many as 46% to 78% of pregnant women experiencing some form of sleep disorder. By the third trimester, nearly 80% of women experience insomnia. As a result, many women seek ways to manage their sleep problems and improve their sleep quality.
Melatonin is a hormone produced by the brain that regulates normal sleep-wake cycles. It is also sold over the counter as a dietary supplement to promote sleep. Melatonin levels tend to increase naturally with each trimester during pregnancy, peaking in the third trimester, and decreasing abruptly after delivery.
Research suggests that melatonin may play an important role in a healthy pregnancy. For example, it is produced in the placenta and may help reduce the risk of pre-eclampsia, preterm birth, and intrauterine growth retardation (IUGR). Melatonin may also affect neurological development and help train the circadian rhythm in a fetus, reducing the likelihood of problems such as brain lesions.
While melatonin is considered safe for use during pregnancy when used under medical supervision, it is important to note that the amount delivered by over-the-counter preparations typically exceeds the quantities normally produced by the body. As a result, there may be potential risks to the developing fetus that are not yet fully understood. Therefore, it is generally advised that pregnant women with sleep problems use medications with a better-characterized reproductive safety profile.

Research on melatonin's safety during pregnancy is limited, with conflicting findings
Sleep disturbances during pregnancy are common, with up to 78% of pregnant women experiencing some form of sleep disorder. Many women seek out natural remedies to manage these sleep problems and improve their sleep quality. Melatonin is a naturally occurring hormone produced by the brain that regulates normal sleep-wake cycles. It is also sold over the counter as a dietary supplement and is popular as a natural sleep aid.
However, research on melatonin's safety during pregnancy is limited and inconclusive. While melatonin is indeed "natural", the amount delivered by over-the-counter preparations typically exceeds the quantities normally produced by the body. As with most supplements, little is known about the impact of these high hormone levels on the developing fetus. Melatonin levels naturally rise during pregnancy, and it is believed that melatonin crosses the placenta and binds to receptors in the fetus, influencing neurological development and the baby's circadian rhythm.
Some studies suggest that melatonin may play a beneficial role in pregnancy. Animal studies have shown that melatonin supplementation can reduce oxidative stress, decrease the risk of pre-eclampsia, preterm birth, and intrauterine growth retardation (IUGR), and improve fertilization rates and embryo quality. Melatonin may also be produced locally in the placenta, with melatonin levels at their highest during the first trimester.
On the other hand, concerns about melatonin use during pregnancy stem primarily from animal research, which has suggested potential negative impacts. Additionally, as melatonin is not classified as a drug or hormone, its production is not monitored by regulatory bodies like the Food and Drug Administration. This means that there may be variability in the dosage and quality of over-the-counter melatonin supplements.
While clinical trials using melatonin during pregnancy for other clinical conditions have not shown major safety concerns, there is a lack of randomized controlled trials specifically examining the safety and efficacy of melatonin for treating sleep disorders during pregnancy.
Therefore, it is recommended that pregnant women experiencing sleep problems consult with their healthcare providers and consider using medications with a better-characterized reproductive safety profile.
