There is a huge range of different things that can affect sleep quality, but all of them have one thing in common, the ability to severely impair both our physical and mental health. When you get insufficient sleep, everything from your focus to your body will begin to suffer.

However, while sleep problems will affect a huge number of people, studies on complementary and integrative health show that the issue can easily be fixed. By taking a sleep medicine like natural sleep aids, you can quickly and efficiently improve your overall sleep quality.

The issue is, certain natural sleep aids improve sleep quality far more than others, so picking the right one can be tough. That is why we have made a list of the best natural sleep remedies, to ensure that everyone can find the perfect supplement to help them get a better night's rest.

All of its ingredients have been carefully chosen and used in their optimal dosages, to ensure that they can improve sleep quality as much as the research suggests they can.

The hormone melatonin is naturally secreted by the pineal gland in the human brain. It is what controls your sleep wake cycle and the speed at which you enter REM sleep, so elevating your melatonin levels with melatonin supplements will improve both of these things (1).

The herb extract ashwagandha and amino acid 5-htp are both known for calming and relaxing abilities, while the latter can cross the blood brain barrier. This will boost mood and reduce stress and anxiety levels, all of which will make it easier for you to fall into a deep sleep (2)(3).

L-theanine is another amino acid that has a calming effect, while also being able to boost cognitive and immune functions, which will prevent low sleep quality (4).

GABA is a neurotransmitter that can offer stress reduction and boost relaxation, as the herbal extract valerian root extract makes it even more potent (5)(6).

The minerals calcium and magnesium both prevent you from having trouble falling asleep and entering REM sleep, boost your mood, and prevent health problems. They also prevent issues known to cause people difficulty sleeping, such as cramps, dry mouth, and jet lag (7)(8).

The vitamin d and b vitamins will then improve sleep quality by accelerating the recovery of your bodily tissues and brain cells. This will help you to wake up feeling fresh and invigorated each day (9)(10)(11).

Containing such a wide range of ingredients from all different sources allows RestAgain to combat mild sleep disturbances and poor sleep quality from virtually every angle, all while having a very fair price tag and a serving size that is easy to swallow.

This comfortably allows it to sit atop our list of the best natural sleep aids currently on the market.


  • The strongest natural sleep aid currently available without a prescription

  • Has not been reported to cause any side effects or adverse reactions

  • Uses ingredients designed to work in perfect synchronicity, like GABA and valerian root

NooCube Sleep Upgrade - Best Natural Sleep Aid Without Melatonin

NooCube Sleep Upgrade
NooCube Sleep Upgrade

Melatonin is put in most natural sleep aids as studies on behavioral sleep medicine show it is among the very best ways to help you sleep. However, some people avoid it as it can cause side effects like nightmares or frequent urination in certain people, making it even harder to sleep.

NooCube Sleep Upgrade is one of the most popular natural sleep aids for people in this group, as it specifically omits melatonin from its formula.

It instead contains:

  • Magnesium

  • Calcium

  • Vitamin d

  • Lemon balm leaf powder

  • Lavender extract

Magnesium reduces the frequency of brain signals to improve relaxation, help you fall asleep, and enjoy a longer, better sleep. Calcium also helps you to fall asleep faster, while a calcium deficiency can lead to chronic insomnia, so boosting your levels with sleep aids prevents this.

Complementary and integrative health studies show that people with a vitamin d deficiency are more likely to develop a sleep disorder. By taking vitamin d you will prevent this while also boosting your natural melatonin production to treat existing circadian rhythm sleep disorders.

Lemon balm leaf powder has been consumed in teas since long before it was available in pill form, as it is known to induce a feeling of calmness.

Studies show that dietary supplements containing it can be used for treating insomnia and anxiety, and can prevent poor sleep and reduce sleep issues by as much as 42% (12).

Lavender extract is a relative of lemon balm that offers similar effects, and it is again proven to help you get to sleep faster and enjoy uninterrupted, high-quality sleep each night, without putting yourself at risk of experiencing any unpleasant side effects (13).

When you combine all of these effects, it is clear that NooCube Sleep Upgrade is far superior to other sleep aids that don't contain melatonin. It can help you treat insomnia and get better sleep each night, without interfering with your body's natural melatonin production.

It is also very reasonably priced and has a serving size of just four capsules, making it one of the most accessible natural sleep aids on the market.


  • Can enhance your circadian rhythm and help to treat or prevent a range of sleep disorders

  • Contains nothing but natural ingredients and absolutely no melatonin

  • Neither it nor its ingredients have been linked to any side effects or adverse reactions

  • Very reasonably priced and offers great value


  • Won't boost your natural melatonin production or levels, so won't work as well as other sleep aids if that is your issue

  • As a relatively new product reviews from past customers are still quite hard to come by

Spruce Rest - The Best Sleep Oil

Spruce Rest is a sleep oil designed to help those who have trouble sleeping reset their sleep wake cycle. It is also among the very best sleep supplements for people who have issues using a supplement form like a tablet or a capsule, as well as those who just don't want to.

Spruce Rest has been formulated from a blend of natural oils that consists of things such as coconut oil, which are rich in medium chain triglycerides (MCTs), a type of healthy fatty acid.

These oils and fats promote sleep by lowering body temperature and suppressing your hunger. The National Sleep Foundation says these two functions will help to improve sleep quality, latency, and duration, all at the same time (14).

MCTs then also offer additional health benefits beyond just being natural sleep aids as well.

They can reduce your risk of developing cardiovascular disease or high blood pressure, boost your energy levels and rate of fat metabolism, fight bacteria, and enhance your brain, gut, and nervous system health.

Manufactured in the United States from nothing but natural, organic, vegan friendly, gluten free, lab grade ingredients, every bottle is third party tested, to guarantee the highest levels of both quality and efficacy.

Throw in a delightful natural vanilla flavour, and Spruce Rest is easily among the best over the counter dietary supplements for people who don't like taking natural sleep aids as pills.


  • Made from only vegan and organic ingredients and has a wonderful vanilla flavour

  • One of the top natural sleep aids for people who don't like taking sleeping pills

  • Offers a range of physical and mental health benefits beyond just helping with sleep problems

  • Every bottle is third party tested, to ensure the highest levels of quality and efficacy


  • Relies a lot on its key active ingredient, while most other medications use a selection of sleep aids

  • There have been some complaints about both the taste and the texture of the oil

Relaxium Natural Sleep Aid - Most Popular Natural Sleep Medicine

Relaxium Natural Sleep Aid is among the most popular natural sleep aids available without a prescription.

It has been designed by a sleep specialist to be non-habit forming and help those who can't get or don't want to use prescription sleep aids fall asleep quicker, stay asleep longer, and then wake up feeling refreshed, alert, and focused, without experiencing side effects.

Its formula contains:

  • Magnesium

  • Ashwagandha

  • GABA

  • Melatonin

  • Valerian root

  • Hops extract

  • Chamomile

  • Passionflower

The majority of these ingredients have been used in many of the natural sleep aids that we have already looked at. However, hops extract, chamomile, and passionflower are quite unique.

Hops extract is an antioxidant with the ability to reduce anxiety and tension, combat stress and depression, make it easier to fall asleep, and treat sleep issues like insomnia, all of which combine to help promote a healthy sleep wake cycle (15).

Chamomile is a popular herbal extract, particularly with older adults, that has long been consumed in teas for the calming effect it produces.

This occurs due to the presence of a chemical called apigenin, which has been shown to reduce stress and anxiety levels, promote relaxation and calmness, and combat issues that impair sleep quality, such as inflammation or an upset stomach, to help you sleep better (16).

Passionflower extract is used in natural sleep aids to treat anxiety, hysteria, insomnia, and seizures. It can achieve this by boosting your natural production of GABA, which makes relaxing and falling asleep considerably easier (17).

There are, however, a few concerns with Relaxium Natural Sleep Aid that need to be addressed.

Firstly, more research is needed on some of the ingredients before both their benefits and side effects can be conclusively proven.

Then there is the fact that a proprietary blend hides the exact dose of valerian root and hops extract that is present, while other ingredients are visibly present in dosages that are a little low.

Don't get me wrong, Relaxium Natural Sleep Aid has become one of the more popular natural sleep aids for a reason. Its useful ingredients can certainly help with some sleep disorders and its reasonable price tag and small serving size of just two capsules are both easy to swallow.

We just want to make sure that you are well aware of issues like the fact that there is an increased risk it won't benefit your sleep as much as some of the other sleeping pills on this list before you purchase it because of its popularity.


  • Comfortably one of the most popular sleep supplements currently on the market

  • Utilises a variety of ingredients that are proven to be beneficial for sleep

  • Very reasonably priced, well reviewed, and easy to get hold of


  • A proprietary blend hides the exact dose of valerian root and hops extract used, making it impossible to accurately determine both the benefits and side effects they could produce

  • More research is needed on some of the ingredients to prove they definitely benefit sleep

Olly Sleep Gummies - The Best Sleep Gummy

Olly Sleep Gummies are a chewable, gluten free sleep aid that is designed to be enjoyable to use while making it easier to relax and drift off to sleep. They even have the ability to help you enjoy a deeper sleep and get back into your regular sleep schedule.

The Olly Sleep Gummies formula consists of the key ingredients:

  • L-theanine

  • Melatonin

  • Chamomile flower extract

  • Lemon balm extract

  • Passionflower extract

L-theanine, melatonin, and chamomile flower extract have all been conclusively proven to help combat sleep issues. However, the dosages used here appear to be a bit low to allow them to produce optimal effects.

There is then evidence to suggest that the other ingredients, lemon balm and passionflower extracts, offer similar benefits as well, although more research is needed before these claims can be considered conclusive.

The active ingredients are then supported by a variety of colours, flavors, sweeteners, and stabilisers, all of which make the Blackberry Zen gummies more enjoyable to eat.


  • Contains multiple ingredients that have been proven to help treat sleep issues

  • Boasts a delicious blackberry flavour that is ideal for those who can't or don't like swallowing capsules or pills

  • They are gluten free and boast a very attractive price tag

  • Highly unlikely to cause any side effects


  • More research is needed on some of the ingredients to conclusively prove they benefit your sleep

  • Some of the ingredient dosages are lower than required for optimal effects

REMfresh - The Best Budget Sleep Aid

REMfresh is a natural sleep aid created to help regulate your sleep schedule and make it easier for you to both drift off and wake up. It also claims to boost the quality and duration of sleep you get, to ensure that you feel totally alert and refreshed when you wake up each morning.

While most sleep supplements use a collection of ingredients to produce results, REMfresh relies on a single ingredient, the sleep hormone melatonin. As one of the very best things to take when it comes to sleep, this is certainly the ingredient to use if you can only pick one.

Admittedly, melatonin supplements have been shown to be more effective when they combine their key ingredient with other sleep aids. This is especially true when you take it in lower doses, like those used in REMfresh.

There is a good reason that we have included it on our list of the best natural sleep aids though, and that is its price. As one of the most affordable sleep supplements on the market, it is a great choice for people who need help sleeping but who are shopping on a tight budget.

So, while it isn't going to be the right choice for everyone, REMfresh certainly fills a gap in the market. With a serving size of just one caplet, it is also a good choice for people who aren't a fan of swallowing pills.


  • Its low price tag is ideal for people shopping for natural sleep aids on a very tight budget

  • Almost 100% melatonin, which is among the top sleep aid ingredients to optimise your sleep cycle

  • The low dosage of melatonin is unlikely to cause any side effects


  • Contains no supporting ingredients to widen its range of potential sleep benefits

  • Uses quite a low dose of melatonin so will be less effective than other sleep supplements

  • Contains several ingredients used solely to create the pill which may cause side effects or allergic reactions

Nuun Rest - The Best Sleep Aid Drink Mix

Nuun Rest is a relaxation tablet designed to promote mental and physical relaxation. Simply dissolve it in 4 to 6 fluid ounces of either hot or cold water and drink to promote a sense of calm, help your body unwind, and reduce restlessness, to help you get a perfect night's sleep.

The Nuun Rest formula includes a number of minor ingredients but relies primarily on magnesium and tart cherry juice powder.

Magnesium is proven to put the body into a restful state, help the brain to slowly ease nerve functions, support muscle relaxation, and prevent cramping.

Meanwhile, the tart cherry juice powder reduces inflammation and muscle soreness (18).

These effects create optimal conditions to help the body rest, repair any damage, and prepare itself for the next day. For best results you also want to take it as close to when you go to bed as possible.

However, if you want a sleep aid that is fairly priced and which you can enjoy as a soothing bedtime drink, Nuun Rest is one of the better sleep aids on the market.


  • Improves quality of sleep and relaxes and calms the body and mind

  • Made entirely from natural ingredients

  • All of the ingredients have been tested and proven to benefit sleep

  • Keto friendly


  • There have been some complaints of a chalky taste

  • Does not dissolve well in cold water and can leave a residue in your cup

  • Drinking so much liquid right before bed can lead to people waking up to urinate

Final Thoughts On The Best Natural Sleep Aids

Taking natural sleep aids is a great way to help you improve your sleep hygiene and get a good night's sleep. However, while most sleep aids will provide some benefits and help you sleep to a certain degree, RestAgain is far more effective than all the other medications on the market.

Research suggests it's ideal for everyone from older adults staying active to travellers dodging jet lag and busy people preventing daytime drowsiness while keeping a hectic schedule. As it induces calmness and helps you to fall asleep, you will get quality sleep and wake up refreshed.

If, for some reason, you feel it is not the best way to improve sleep for you, one of the other natural sleep aids on our list surely will be. For everyone else though, we highly recommend that you give RestAgain a try and see all of the sleep improvements it can offer for yourself.
