Sleep plays a crucial role in our health and well-being. Studies have shown that people who regularly get fewer than seven hours of sleep per night have a higher prevalence of diabetes, obesity, and high blood pressure. Many people struggle to get a good night's sleep, and some turn to sleep vitamins or supplements to help them. But do these sleep vitamins work? While melatonin, a hormone that helps regulate our sleep-wake cycle, has been shown to be effective in improving sleep in some cases, it is important to consider potential side effects and underlying causes of sleep issues. Other non-pharmaceutical measures, such as increased physical activity, yoga, and acupuncture, can also promote better sleep.

What You'll Learn
Melatonin supplements may help with jet lag and insomnia
Sleep is essential for health and well-being, and numerous studies have documented the relationship between health and the quantity and quality of sleep. While there are many non-pharmaceutical measures to improve sleep, such as physical activity, yoga, and acupuncture, some people turn to sleep supplements. Melatonin is a naturally occurring hormone that helps regulate our sleep-wake cycles, also known as circadian rhythms. It is produced by the brain's pineal gland in the absence of light, such as during the night.
Melatonin supplements are lab-made versions of this hormone and are commonly used to treat jet lag and insomnia. Jet lag is a temporary condition that occurs when you travel across multiple time zones, disrupting your circadian rhythms and causing symptoms like insomnia, daytime sleepiness, and irritability. Melatonin supplements have been found to decrease jet lag symptoms in people crossing five or more time zones when taken close to the local bedtime at the destination. It can also help reduce recovery time after a long flight. However, it is important to note that the safety of melatonin supplementation during breastfeeding is not yet fully understood.
Additionally, melatonin can be prescribed as a long-term treatment for insomnia. It is recommended to take melatonin at your normal bedtime, not earlier than 8 pm and not later than 4 am, and it can be used for up to five consecutive nights. Melatonin supplements may have side effects, including rare cases of mood changes, depression, anxiety, or very low blood pressure. It is important to consult a doctor before taking melatonin, especially if you are considering using recreational drugs or drinking alcohol, as this can affect its efficacy and safety.
While melatonin supplements may provide some benefits for jet lag and insomnia, it is always advisable to consult a healthcare professional before starting any new medication or supplement to ensure it is safe and appropriate for your individual needs.

Sleep vitamins are not regulated by the US Food and Drug Administration
Sleep is crucial for health and well-being. Studies have shown that people who regularly get fewer than seven hours of sleep per night are at a higher risk of developing diabetes, obesity, and high blood pressure, which are major precursors to heart attacks and strokes. Sleep deficiency may also impair learning, problem-solving, decision-making, and emotional control.
To improve sleep quality, experts recommend sticking to a consistent sleep schedule, limiting caffeine and alcohol, and creating a cool, dark, and quiet sleep environment. However, despite these recommendations, about 18% of American adults turn to medication to aid their sleep, including over-the-counter pills and prescription medications.
One popular option is melatonin, a hormone that helps regulate the body's circadian rhythm or sleep-wake cycle. Melatonin supplements, including gummies, are generally considered safe for short-term use and can be effective for those with jet lag, shift workers, or those with delayed sleep-wake disorders. However, it's important to note that sleep vitamins and supplements are not regulated by the US Food and Drug Administration, which means they are not tested for safety or effectiveness and could contain hidden ingredients or inaccurate doses.
For example, one study found major discrepancies between the listed melatonin dose on a supplement label and the actual amount in each dose. Additionally, some supplements may add serotonin, which can pose health risks due to potential drug interactions. Therefore, it is recommended to consult a healthcare professional before taking any sleep supplements and to prioritize treating the underlying causes of sleep problems, such as improving sleep habits and addressing lifestyle factors.

Sleep supplements may not be safe for everyone
Additionally, sleep supplements may not be effective for everyone. While melatonin can help reduce the time it takes to fall asleep, increase total sleep time, and improve sleep quality, it may not be effective for those with insomnia or sleep troubles related to underlying issues such as sleep apnea, restless leg syndrome, or anxiety. In these cases, melatonin may only mask the underlying problem, and treating the underlying issue may be more effective in resolving sleep difficulties.
It is also important to be cautious when taking over-the-counter sleep aids that contain antihistamines, such as Benadryl, Tylenol PM, and Advil PM. While these medications can help with allergies, they should not be taken solely to aid sleep. Antihistamines can cause dangerous overdoses if taken in large amounts or mixed with other drugs or alcohol. They can also cause sedation and impair functioning the next day.
Instead of relying solely on sleep supplements, it is recommended to practice good sleep hygiene habits, such as sticking to a consistent sleep schedule, limiting caffeine and alcohol intake, creating a cool, dark, and quiet sleep environment, and engaging in calming activities before bedtime. If sleep difficulties persist, it is best to consult a healthcare professional or a specialist in sleep medicine to diagnose any underlying issues and determine the most appropriate treatment.

Sleep supplements may not be a long-term solution
Dr Lee-Iannotti states that "Your insomnia or sleep troubles could actually be related to sleep apnea, restless leg syndrome, a periodic limb movement disorder, anxiety or depression...In these cases, melatonin won't help – it will only mask it." It is important to address the root cause of sleep issues, and melatonin should be coupled with lifestyle choices that promote good health, such as good nutrition, exercise, and good sleep practices.
Additionally, melatonin supplements are not regulated by the U.S. Food and Drug Administration and are not tested for safety or effectiveness. They can also vary in the amount of melatonin in each dose and may contain hidden ingredients. It is always best to consult a healthcare professional before taking any supplement to ensure it is right for you and does not interact with any medications you are taking.
Furthermore, obsessing over how much sleep one gets can create an "insomniac response" and lead to associating the bed with stress and anxiety. This can create a vicious cycle where the individual becomes anxious about not getting enough sleep, which then interferes with their ability to fall asleep. Instead, it is recommended to focus on creating a relaxing bedtime routine and environment, such as keeping the bedroom cool, dark, and quiet, and engaging in calming activities before bed.

Sleep supplements may not be necessary
Additionally, sleep supplements are not regulated in the same way as prescription medications. Dr. Moses points out that companies selling complementary medicines, including sleep vitamins and herbal remedies, are not required to prove the efficacy of their products. As a result, the claims made by these companies may not be supported by scientific evidence. Sleep supplements could, therefore, be marketed as sleep aids without actually delivering significant improvements in sleep quality.
Furthermore, sleep supplements may come with potential side effects and health risks. While melatonin is generally considered safe in the short term, some people may experience daytime sleepiness, tiredness, morning drowsiness, headaches, and dizziness. Melatonin can also interact with certain drugs, including those used for seizures, high blood pressure, diabetes, and immunosuppression. It is important to consult a healthcare professional before taking melatonin to ensure it is safe and to determine the appropriate dosage.
Finally, there are alternative approaches to improving sleep quality that do not involve sleep supplements. These include lifestyle changes such as sticking to a consistent sleep schedule, limiting caffeine and alcohol intake, creating a cool and comfortable sleep environment, and engaging in calming activities before bedtime. By addressing sleep hygiene and making behavioural changes, it may be possible to enhance sleep quality without resorting to sleep supplements.
