There are various natural remedies that may assist you in achieving better sleep, such as melatonin, magnesium, and valerian root (Valeriana officinalis). However, it is essential to understand that even natural sleep aids should not be seen as substitutes for healthy sleeping habits. Adequate sleep is crucial for your overall health and well-being. Quality sleep enables your body and brain to function optimally, enhancing your learning capabilities, memory retention, decision-making skills, and even creativity.

Moreover, insufficient sleep has been associated with an increased risk of developing serious health conditions, including heart disease, diabetes, and obesity. Despite the known benefits of sleep, a significant number of individuals struggle to achieve enough restful slumber each night, with approximately 20% of adults experiencing occasional symptoms of insomnia. Establishing good quality sleep often begins with adopting proper sleep practices and habits. However, for some individuals, these measures may not be sufficient. If you're seeking additional support for a restful night, you might want to explore the following ten natural sleep-enhancing supplements.

1. Melatonin

Melatonin is a hormone that your body naturally produces to communicate to your brain that it's time to rest. The cycle of production and release of this hormone is influenced by the time of day, as melatonin levels typically increase in the evening and decrease by morning.

This characteristic has led to the widespread use of melatonin supplements as a popular sleep aid, particularly useful in situations where the natural melatonin cycle is disrupted, such as during long-haul flights (jet lag). Numerous studies have indicated that melatonin can enhance the quality and duration of daytime sleep, proving particularly advantageous for individuals, such as shift workers, whose schedules necessitate sleeping during daylight hours.

Moreover, melatonin has shown potential in improving overall sleep quality among individuals suffering from sleep disorders. It notably reduces the time required to fall asleep, known as sleep latency, while also extending the total sleep duration. Although some studies have not found significant positive effects of melatonin on sleep, these instances are relatively rare. The studies that did observe beneficial outcomes typically administered doses ranging from 3 to 10 milligrams (mg) of melatonin before bedtime. Generally, melatonin supplements are considered safe for adults when utilized for short durations; however, further research is necessary to ascertain their long-term effects. Additionally, melatonin is not recommended for pregnant or nursing women due to the limited research available regarding its safety and effectiveness in these populations.

In summary, melatonin supplements can enhance sleep quality when taken in doses between 3 to 10 mg, especially beneficial for those experiencing jet lag or working night shifts.

2. Valerian Root

Valerian (Valeriana officinalis) is an herb indigenous to both Asia and Europe, renowned for its root, which has been widely utilized as a natural remedy for various conditions, including anxiety, depression, and the symptoms associated with menopause.

This herb has gained popularity as a sleep-enhancing herbal supplement, particularly in regions like Australia and Canada, where similar natural treatments are often sought. Despite its widespread use, research findings regarding valerian's effectiveness remain somewhat inconsistent.

A review of studies highlighted that postmenopausal and menopausal women reported improvements in sleep quality and a reduction in sleep disorder symptoms after consuming valerian. In another notable study involving individuals post-heart surgery, participants who took 530 mg of valerian nightly for a month experienced marked enhancements in sleep quality, latency, and duration compared to those receiving a placebo.

In a separate investigation involving 39 individuals undergoing hemodialysis, nightly intake of 530 mg of valerian root over a month resulted in significant improvements in sleep quality, alongside reductions in anxiety and depression when contrasted with a placebo group. Nevertheless, it's important to note that many of the improvements observed in these studies were primarily subjective, relying heavily on participants' self-assessments of sleep quality rather than on objective metrics such as brain wave activity or heart rate variability.

Some research has suggested that the positive effects of valerian may be minimal, indicating only a slight enhancement in sleep latency. Despite the absence of robust objective evidence, short-term usage of valerian root seems to be safe for most adults, with only minor and infrequent side effects reported. Therefore, adults may consider trying valerian root to evaluate its effects on their sleep.

However, the long-term safety of valerian, particularly for specific populations such as pregnant or nursing women, remains uncertain. Generally, valerian root is favored as a supplement that could potentially enhance sleep quality and alleviate sleep disorder symptoms when taken in doses ranging from 300 to 600 mg, at least for some users. More comprehensive studies are warranted to assess the long-term safety of its use.

3. Magnesium

Magnesium is an essential mineral that plays a crucial role in numerous biological processes within the human body, significantly contributing to brain function and heart health. This vital nutrient is also believed to promote relaxation for both the mind and body, facilitating the process of falling asleep. Research indicates that the calming effects of magnesium may be partially attributed to its role in regulating melatonin production. It is well-documented that magnesium can help relax muscles, thereby inducing a state conducive to sleep.

A variety of magnesium supplements are available on the market, including formulations that pair magnesium with other sleep-enhancing ingredients such as glycine or melatonin. For instance, one study demonstrated that a combination of magnesium, melatonin, and vitamin B effectively addressed insomnia, regardless of its underlying causes.

Additionally, magnesium appears to enhance levels of gamma-aminobutyric acid (GABA), a neurotransmitter that promotes calmness. Various studies suggest that inadequate magnesium levels in the body may correlate with sleep disturbances and insomnia. Conversely, increasing magnesium intake through supplementation may positively influence both the quality and duration of sleep.

A comprehensive review of three studies involving older adults revealed that magnesium supplementation could significantly decrease the time it takes to fall asleep when compared to a placebo. It is important to note that this review primarily focused on older individuals, who may have started with lower blood magnesium levels. Therefore, it remains uncertain whether similar effects would be observed in those with a higher dietary intake of magnesium.

In another investigation, participants with polycystic ovary syndrome who supplemented with 250 mg of magnesium and melatonin for eight weeks reported a marked improvement in sleep quality. Nevertheless, further studies are warranted to fully understand the impact of magnesium supplements on sleep when administered independently. Overall, magnesium's relaxing properties may significantly enhance sleep quality. While most research employs daily doses ranging from 225 to 729 mg, it is advisable not to exceed 350 mg per day unless directed by a healthcare professional.

4. Lavender

The lavender plant, known for its striking purple flowers, is prevalent across nearly every continent. When dried, these flowers serve a multitude of purposes in households around the world. Additionally, the calming aroma of lavender is renowned for its potential to enhance sleep quality. In fact, numerous studies indicate that inhaling lavender oil shortly before bedtime can significantly improve sleep quality for both individuals with insomnia and those without it.

One particular study involving older adults diagnosed with dementia suggested that lavender aromatherapy effectively alleviates symptoms of sleep disturbances, leading to an increase in total sleep duration and a decrease in the number of participants waking up too early, struggling to fall back asleep. Another research project highlighted that lavender aromatherapy not only enhanced sleep quality but also lowered anxiety levels over a span of 15 days among 60 individuals suffering from coronary artery disease.

While lavender aromatherapy is generally regarded as safe, it's important to note that ingesting lavender can lead to side effects such as nausea, belching, and diarrhea in some individuals. Essential oils, including lavender, are primarily intended for aromatherapy use rather than oral consumption. Moreover, it is essential to recognize that the body of research regarding the impact of lavender supplements on sleep is still somewhat limited. Therefore, additional studies are necessary before drawing definitive conclusions.

In summary, while lavender aromatherapy shows promise in enhancing sleep quality, further investigation into the safety and efficacy of lavender supplements is required.

5. Passionflower

Passionflower, scientifically recognized as Passiflora incarnata and commonly referred to as maypop, is widely regarded as an effective herbal remedy for combating insomnia. Native primarily to North America, specific species of this enchanting plant are now cultivated across various continents, including Europe, Asia, Africa, and Australia, showcasing its global appeal.

Research has indicated that passionflower exhibits sleep-enhancing properties, as evidenced by various animal studies. However, the efficacy of passionflower in humans seems to be influenced by the form in which it is consumed. A notable older study compared the effects of passionflower tea against a placebo tea made from parsley leaves.

In this study, participants consumed each type of tea approximately one hour before bedtime for a duration of one week, with a one-week washout period in between. Each tea bag was steeped for ten minutes, during which objective measurements of sleep quality were recorded by researchers. At the conclusion of the three-week investigation, findings showed no significant improvements in sleep quality based on objective measurements. Nevertheless, participants reported a subjective increase in sleep quality, rating it about 5% higher after consuming passionflower tea compared to the parsley tea week.

Further supporting its efficacy, a recent study involving individuals suffering from insomnia indicated that those who took passionflower extract over a two-week timeframe experienced noteworthy enhancements in specific sleep metrics when compared to those on a placebo. The parameters that showed improvement included:

• total sleep duration
• sleep efficiency, defined as the ratio of time spent asleep to the time spent awake in bed
• wake time after initially falling asleep

While additional research is warranted, it is important to emphasize that passionflower is generally considered safe for adult consumption. Presently, it appears that the most pronounced benefits of passionflower are derived from its consumption in the form of tea or extract rather than as a dietary supplement. Therefore, while passionflower tea or extract may offer slight improvements in sleep quality for some individuals, the evidence remains inconclusive, and further studies are essential to draw definitive conclusions.

6. Glycine

Glycine is a vital amino acid that significantly influences the functioning of the nervous system and has potential benefits for enhancing sleep quality. The exact mechanisms through which it operates are not entirely clear; however, it is believed that glycine plays a role by lowering body temperature as bedtime approaches, signaling to the body that it is time to sleep.

A study conducted in 2006 involving participants who struggled with sleep revealed that those who consumed 3 grams (g) of glycine or a placebo right before sleep reported feeling less fatigued the following morning. They also noted an increase in their overall liveliness, energy levels, and mental clarity after waking.

Following this, a 2007 investigation examined the impacts of glycine on individuals with sleep difficulties, using objective measurements such as brain wave activity, heart rate, and breathing patterns during sleep. Participants who ingested 3 g of glycine before sleep exhibited notable improvements in their sleep quality compared to those who received a placebo, and they also fell asleep more quickly.

Moreover, glycine has been shown to enhance daytime performance in those experiencing temporary sleep deprivation, as shown in a small study from 2012. In this research, participants had their sleep restricted for three consecutive nights and took either 3 g of glycine or a placebo before sleep. The glycine group reported significant reductions in feelings of fatigue and daytime drowsiness.

Glycine is available for purchase in pill or powdered form, which can be mixed with water. A safe dosage appears to be up to 0.8 g per kilogram of body weight daily, although more research is warranted. Many participants in sleep studies typically took around 3 g each night.

To naturally boost your glycine intake, consider incorporating foods rich in this amino acid into your diet, such as:

• Animal products like bone broth, meat, poultry, fish, and eggs
• Legumes and beans
• Dark leafy greens such as spinach and kale
• Cabbage
• Fruits like bananas and kiwis

Incorporating glycine into your nightly routine may help you fall asleep more swiftly and enhance the overall quality of your sleep. Generally, a dosage of about 3 g taken before bedtime is recommended in most studies.

7. Cannabidiol (CBD)

Cannabidiol, commonly known as CBD, is a compound extracted from hemp, and it is commonly found in a variety of products such as oils and capsules. This compound is particularly noteworthy because it contains minimal amounts of tetrahydrocannabinol (THC) — the psychoactive element typically associated with cannabis — meaning that using CBD products does not induce the same euphoric high as traditional cannabis.

Interestingly, a range of studies suggests that CBD may help alleviate anxiety and serve as a natural sleep aid. For example, a comprehensive review encompassing 34 studies indicated that CBD could significantly reduce insomnia symptoms when used on its own or in combination with THC in equal proportions.

In another research involving 72 individuals suffering from anxiety, findings revealed that the incorporation of CBD into their routine improved sleep quality and diminished anxiety levels for nearly 67% and 79% of participants, respectively, within just the first month. However, it is essential to note that a 2020 research review emphasized the necessity for further high-quality studies before CBD can be routinely suggested for managing sleep disorders.

Additionally, research on the long-term safety of CBD remains limited, and it is advised that pregnant or breastfeeding individuals avoid its use. Moreover, the legal status of CBD varies across different regions, as it is still considered a controlled substance in certain areas, which raises important questions regarding its availability and use. While preliminary research indicates that CBD could potentially enhance sleep quality and alleviate anxiety symptoms, it is crucial to emphasize that more rigorous studies are essential to validate these claims.

8–10. Additional Sleep-Enhancing Supplements

In the realm of sleep aids, numerous supplements are available, yet not all possess robust scientific backing.

The following substances may offer potential benefits for sleep enhancement, but further scientific scrutiny is essential:

• Tryptophan: A review of several studies indicates that a daily intake of at least 1 g of tryptophan could enhance sleep quality and diminish the time individuals remain awake during the night.
• Ginkgo biloba: Historical research suggests that consuming approximately 240 mg of ginkgo biloba 30–60 minutes prior to bedtime may alleviate stress, foster relaxation, and support sleep onset. Promising results have also emerged from animal studies.
• L-theanine: Daily supplementation with up to 200 mg of L-theanine may promote improved sleep and relaxation. Research involving animals indicates that its effectiveness may increase when paired with GABA or magnesium.

Kava is another plant that has garnered attention for its potential sleep-inducing properties in various studies. Native to the South Pacific islands, its root is traditionally brewed into a tea and is also available in supplement format. Nevertheless, the use of kava has been associated with significant liver damage, likely due to poor quality production or contamination. Some nations, including Germany and Australia, have previously imposed temporary bans or issued warnings about kava consumption.

Exercise caution when considering kava; ensure that any supplements purchased are verified by a reputable third-party organization. While tryptophan, ginkgo biloba, and L-theanine show promise in promoting sleep, they lack extensive empirical support, necessitating further research to draw definitive conclusions. Approach kava with careful consideration.

Alternative Over-the-Counter (OTC) Sleep Solutions

Among the various OTC sleep aids available, diphenhydramine and doxylamine succinate stand out as common options. Both of these compounds are classified as antihistamines, which are primarily used for allergy relief.

• Diphenhydramine, the main ingredient in popular allergy medications such as Benadryl, is not specifically designed for sleep enhancement. However, it often induces drowsiness, making it a commonly used sleep aid. You can also find this ingredient in products like ZzzQuil, Unisom SleepGels, and Unisom SleepMelts.
• Doxylamine succinate serves as the active component in Unisom SleepTabs and is also present in Nyquil. Like diphenhydramine, it has sedative effects that may help in achieving sleep.

The scientific backing for using either diphenhydramine or doxylamine succinate as effective sleep aids is rather limited. Numerous health professionals advise against the frequent use of these medications, particularly for vulnerable groups such as the elderly.

Potential side effects may encompass dizziness, an increased risk of falls, and cognitive decline. Furthermore, prolonged use of OTC sleep medications can lead to tolerance. Continuous use of anticholinergic drugs, including antihistamines, may heighten the risk of developing dementia over time. If you are contemplating the use of these sleep aids, it is advisable to limit their use to occasional instances, as comprehensive research on their long-term safety and efficacy is still lacking.

Individuals suffering from respiratory ailments, hypertension, or cardiac issues should avoid both diphenhydramine and doxylamine succinate entirely, as they may trigger adverse nervous system responses that result in tachycardia or an increased heart rate. For older adults, particularly those with liver or kidney problems, the use of diphenhydramine is discouraged due to a higher likelihood of experiencing adverse effects.

While the antihistamines diphenhydramine and doxylamine succinate may assist in promoting sleep, it is important to remember that their primary intent is not sleep induction. Stronger evidence is necessary to fully support their use. Always consider the potential side effects before starting these medications.

Risks and Precautions

Before incorporating any herbs or over-the-counter (OTC) medications for sleep into your routine, it is crucial to consult with a healthcare professional, particularly due to the possibility of interactions with existing medications, including blood thinners. If your sleep difficulties extend beyond two weeks, it is advisable to inform your doctor.

While many OTC sleep aids typically result in only minor side effects, caution is warranted as the long-term implications of several of these aids remain inadequately understood. Below is a list of side effects associated with specific sleep aids, noting that some of these effects are based on anecdotal evidence or limited studies, often observed in individuals taking high doses:

• Melatonin: potential minor side effects include headache, nausea, and dizziness.
• Valerian root (Valeriana officinalis): may cause diarrhea, headache, nausea, and heart palpitations.
• Magnesium: diarrhea, nausea, and vomiting can occur, particularly at high doses.
• Lavender : might lead to nausea, belching, and diarrhea.
• Passionflower: in rare instances, dizziness and confusion have been reported.
• Glycine : occasionally linked to soft stools and abdominal pain.
• Tryptophan: possible mild nausea and vomiting.
• Ginkgo biloba: generally presents mild and rare side effects such as diarrhea, headache, nausea, and rash.
• L-theanine: typically shows no confirmed side effects when consumed alone; however, it may cause diarrhea and abdominal pain when taken with L-cystine.

Pregnant or nursing individuals should always consult their healthcare provider before trying any supplements. Generally, these groups should steer clear of most supplements due to the lack of substantial research confirming their safety during these critical life stages. However, magnesium, glycine, and tryptophan play vital roles in fetal development, and they need not be avoided if you are pregnant or nursing. Still, it is essential that a healthcare professional guides you on the appropriate dosage to mitigate potential side effects.

In summary, while many OTC sleep aids are associated with only minor side effects when used for short durations, it is vital to seek advice from a healthcare professional prior to using any herbs or OTC medications for sleep, especially for pregnant or nursing women who should generally avoid most of these products.
