Sleep is essential for our health and well-being, but many people struggle to get enough shut-eye. While behavioural changes and lifestyle adjustments are often recommended as the first line of treatment for sleep issues, some individuals may also opt for supplements to promote better sleep. Melatonin is a popular choice as it is a hormone that our body produces naturally to signal that it's time to sleep. Other supplements that have been linked to improved sleep include valerian, CBD, lavender, passionflower, chamomile, glycine, and tryptophan. However, it's important to note that the effectiveness of these supplements varies, and some may have side effects or interact with certain medications. Always consult a healthcare professional before taking any supplement to ensure it is safe and suitable for your individual needs.

What You'll Learn
Melatonin supplements
Melatonin is a hormone that is naturally produced by the body to regulate the sleep cycle. The body's melatonin levels rise about two hours before bedtime and fall in the morning. However, some people may not produce enough melatonin, leading to sleep difficulties. In such cases, melatonin supplements can help induce sleep.
While melatonin supplements are generally safe for short-term use, they may cause side effects such as drowsiness, headaches, and vivid dreams or nightmares. They should not be used by individuals who are pregnant or breastfeeding or have specific medical conditions such as autoimmune disorders, seizure disorders, or depression. Additionally, those with diabetes or high blood pressure should consult a healthcare provider before taking melatonin.

Valerian root
The effectiveness of valerian root as a sleep aid has been the subject of numerous studies, with mixed results. Some studies suggest that valerian root helps individuals fall asleep faster, improves sleep quality, and reduces anxiety and depression. For example, a 2018 research review found that menopausal and postmenopausal women experienced improved sleep quality and a reduction in sleep disorder symptoms after taking valerian. Additionally, a 2021 study showed that taking 530 mg of valerian root before bed for one month improved sleep quality, anxiety, and depression compared to a placebo.
However, other studies have found conflicting results, with some indicating that valerian root may not be significantly more effective than a placebo in improving sleep. The discrepancies in the findings may be due to variations in study design, valerian preparation, and dosing, as well as individual differences. While valerian root is generally considered safe, it is important to consult a healthcare provider before taking any herbal supplement, especially if you are pregnant, breastfeeding, or taking other medications.
Overall, while valerian root may offer some benefits for sleep, it is important to manage expectations and understand that individual results may vary. It may be worth trying valerian root as a natural sleep aid, but it should not be solely relied upon to address sleep disorders or chronic insomnia. Combining valerian root with other behavioural and lifestyle changes recommended by sleep experts may be a more comprehensive approach to improving sleep quality.

CBD
Cannabidiol, or CBD, is a popular supplement that is often used to improve sleep. CBD is a derivative of the cannabis plant and is non-psychoactive, meaning it does not produce the "high" associated with THC (tetrahydrocannabinol). While CBD is commonly used to reduce pain, anxiety, and inflammation, its impact on sleep is less understood.
Research on the effectiveness of CBD for sleep is mixed. Some studies suggest that CBD may help improve sleep quality, especially for those with anxiety or insomnia. For example, a 2021 review found that CBD, alone or in combination with THC, improved sleep symptoms for some participants. Additionally, a 2023 study reported that CBD users experienced improved sleep and a 2014 case series suggested that CBD may improve REM sleep behaviours in people with Parkinson's disease. However, other studies, including a 2024 randomized controlled trial, found that CBD did not significantly improve sleep compared to a placebo.
The mechanism by which CBD may improve sleep is not fully understood. One theory suggests that CBD's ability to relieve anxiety, stress, and pain may indirectly improve sleep quality. CBD may also help inhibit the release of cortisol, a hormone that can keep people awake, thereby promoting relaxation. Additionally, CBD may help the body transition from rapid eye movement (REM) sleep to non-rapid eye movement (NREM) sleep more quickly.
When considering CBD for sleep, it is important to consult a healthcare professional to ensure safety and effectiveness. Factors such as dose, product type, and individual characteristics can impact the effectiveness of CBD for sleep. While CBD is generally considered safe, it may cause mild side effects such as drowsiness, gastrointestinal issues, or interactions with other medications. It is also important to choose high-quality CBD products from reputable brands to minimize potential risks.

Passionflower
A typical dosage of passionflower is 500 mg, which has been shown to decrease anxiety and increase sedation compared to a placebo. In one study, participants who received passionflower before a dental procedure experienced reduced anxiety and limited memory loss associated with the procedure. Passionflower has also been found to be effective in treating opioid use disorder, with fewer withdrawal symptoms compared to a placebo.

Warm milk, chamomile tea, or tart cherry juice
Warm milk, chamomile tea, and tart cherry juice are popular home remedies for sleep troubles. While there is limited scientific evidence for their effectiveness, these natural sleep aids have been used for years and may be worth trying.
Warm milk is a well-known bedtime ritual, and for good reason. Studies suggest that drinking warm milk before bed may help you sleep better. In one study, participants who drank warm milk and honey for three days reported improvements in their sleep. Another study found that adults over 60 who drank fermented milk for three weeks experienced reduced nighttime wakings. Warm milk is also believed to be especially helpful for those who have difficulty falling asleep.
Chamomile tea is another popular natural sleep aid. It has been used to promote relaxation and sleep since ancient times. Chamomile is considered a mild sedative, which means it may help to relax the nervous system and promote sleep. It is naturally caffeine-free, but it's important to check the label if you're buying a blend to ensure it doesn't contain other teas with caffeine.
Tart cherry juice is also gaining recognition as a potential sleep aid. Studies suggest that consuming tart cherry juice leads to better and longer sleep. This may be due to its tryptophan and melatonin content, which can help regulate sleep. Drinking a glass of sugar-free tart cherry juice about an hour before bed could improve your sleep quality. In addition to its sleep benefits, tart cherry juice is also packed with antioxidants, which can improve overall health and muscle recovery.
While these natural remedies may be helpful, it's important to remember that consistent sleep schedules and other healthy sleep habits are more crucial for achieving good sleep. Additionally, always consult your doctor before taking any new supplements or making significant changes to your routine.
