However, while many people will seek out a prescription medication, which can be dangerous, for most healthy adults the route of their issues will usually be something quite simple and easy to fix. The most common issue will be that their natural melatonin levels are too low.

RestAgain - The Best Melatonin Supplement Overall


RestAgain is a sleep aid from FA Nutra Ltd has been popular for some time in the United Kingdom which has seen its popularity continue to grow after launching in the United States recently. It’s the highest dosed sleep supplement on the market by quite a long way and probably represents not only the most effective, but best value for money option on our list.


It is created to regulate sleep cycles by helping you fall asleep quicker, stay asleep longer, and enjoy a better sleep each night. Unlike a lot of other supplements RestAgain sticks to the optimal and clinically proven dosages of each of its ingredients. This does mean that it’s a 3-capsule supplement, whereas most of it’s competition only provide one, this does have some extra positives aside from just meaning you get more ingredients, which we’ll come to shortly.

Its formula of natural ingredients consists of melatonin, ashwagandha, GABA, l-theanine, 5-htp, magnesium, valerian root, calcium, vitamin b6, vitamin b12, and vitamin d.

Melatonin is a naturally secreted hormone that controls your sleep wake cycle. It is produced in the human brain by the pineal gland to help you enter REM sleep faster, so, the higher your melatonin levels go, the easier this will be to achieve (1). RestAgain splits it’s 10mg dosage across 3 tablets, meaning that you can optimise your own dose, or just dive straight in to the high end of melatonin dosages to make sure that it works to get you off to sleep as quickly as possible. And it’s recommended that you start with just 2 pills of RestAgain a day so your body get’s used to taking melatonin.


Ashwagandha is a herb extract and 5-htp is an amino acid, but both serve virtually the same purpose in sleep aids. They have calming and relaxing abilities that boost your mood and ease stress and anxiety levels, to prevent sleep difficulties and help you drift off faster (2)(3). Both of these are also in their correct dosages with Ashwagandha being shown to be most effective for aiding sleep at around 300mg as well as reducing stress and anxiety.

Like 5-htp, l-theanine is another amino acid known for its calming effect. However in this case it also boosts your brain and immune functions too, to further prevent low sleep quality (4).


The neurotransmitter GABA reduces stress and boosts relaxation, and helps your body produce it’s own melatonin making RestAgain even more potent and probably the strongest melatonin supplement. While the herbal extract valerian root makes its effects even more potent (5)(6).

Calcium and magnesium are both minerals that stop you either having trouble falling asleep or entering REM sleep. They also boost your mood and prevent health issues, many of which cause sleep issues, such as cramps, dry mouth, and jet lag (7)(8).

The vitamins then prevent you from developing deficiencies which could cause sleep disorders while accelerating the recovery of your body and brain cells. This will enhance your sleep wake cycle and ensure that you enjoy a rejuvenating sleep each night (9)(10)(11).


The variety of ingredients that RestAgain contains, in addition to its melatonin content, all of which are present in their optimal dosages, allows it to tackle sleep disorders from more angles than most melatonin supplements.

This virtually guarantees you will have no trouble staying asleep or enjoying deep sleep, while the reasonable price tag and serving size both make it a dietary supplement that is easy to use for the vast majority of people.


  • A natural sleep aid that can rival any prescription sleep medicine

  • Contains an optimal dose of melatonin per serving

  • No side effects or adverse reactions have been reported

  • Its varied, high-quality ingredients are optimally dosed, proven to benefit sleep, and work in perfect harmony with the melatonin

  • Very reasonably priced


  • Can improve sleep quality from a variety of angles


  • As a fairly new sleep aid, reviews from past customers are still limited

NooCube Sleep Upgrade - The Best Sleep Aid To Boost Your Natural Melatonin Production

NooCube Sleep Upgrade

Despite the benefits that they can have, there are some people who choose to avoid melatonin supplements, for one reason or another.

If these people are suffering from low melatonin levels, they will therefore need to find a dietary supplement to boost their nature made melatonin instead. In this category of supplements, you simply won't find any better options than NooCube Sleep Upgrade.


A supplement specifically designed for people who avoid melatonin, the NooCube Sleep Upgrade formula instead consists of magnesium, calcium, vitamin d, lemonbalm leaf powder, and lavender extract.

Magnesium slows the speed at which the brain sends signals. This will increase your level of relaxation, make it easier for you to fall asleep quickly, and ensure that you enjoy a longer, better quality sleep.

Calcium supplementation will also help you get to sleep faster, while a calcium deficiency can actually lead to chronic insomnia, so preventing this from occurring will stop the issues before they develop.

Much like with calcium, people who are deficient in vitamin d are also more likely to have trouble sleeping.


Taking a vitamin d supplement will therefore not just stop this from happening but will also boost your natural production of melatonin and directly combat any existing circadian rhythm sleep problems.

Lemon balm leaf powder is an extremely popular ingredient used in herbal teas, as it is proven to help induce a feeling of calmness.

Recent studies on complementary and integrative health have even found that it can reduce anxiety, directly combat insomnia, and prevent poor sleep and sleep problems by as much as 42%.

The only ingredient that we haven't looked at before, lavender extract, is also often consumed in teas for its calming effects. It has been proven to help you fall asleep much faster and enjoy rejuvenating sleep of a good quality, without any risk of you experiencing any side effects (17).


When you combine the effects of all the ingredients that NooCube Sleep Upgrade contains, it is an ideal sleep supplement to help people who do not want to take melatonin supplements to treat insomnia and improve the quality of sleep that they get each night.


  • Has the ability to aid your circadian rhythm and treat a range of other sleep problems

  • Contains nothing but natural ingredients and does not include any melatonin

  • Neither the formula or its ingredients have been linked to any side effects or adverse reactions

  • Very fairly priced and offers great value


  • Will not boost your melatonin level directly so may not be as effective as extended release melatonin supplements for some people


  • As quite a new product, reviews from past customers are still quite limited and it can be hard to get hold of in certain areas

Elm & Rye Melatonin - The Best Pure Melatonin Supplement

Elm & Rye Melatonin is a melatonin supplement that contains nothing but the sleep hormone itself. This makes it a perfect choice for people who feel that their natural melatonin levels are dropping but who don't want to use lots of strange ingredients.

Available in a choice of either gummies or capsules, the product ensures that everyone can use Elm & Rye Melatonin, regardless of how they like to take dietary supplements.


Each serving also packs an optimal daily dosage into just a single capsule or gummy, so you don't have to worry about consuming huge servings. These then contain a small amount of stabilisers and flavourings, to make them as enjoyable to take as possible.

While it is fairly reasonably priced, it becomes even more so when you buy the product in bulk. The more packs of Elm & Rye Melatonin you purchase, the greater the savings will be.

This makes it an ideal option that is attainable for virtually anyone who is keen on taking melatonin supplements to promote restful sleep.



  • Its only active ingredient is pure melatonin

  • Available as both capsules and gummies

  • Reasonably priced and sold in a range of purchase options


  • Relying solely on melatonin makes it less well rounded than other sleep medicine

  • The actual dosage of melatonin present per serving is not disclosed

Penguin Melatonin Gummies - The Best Melatonin Gummies With Oils

Penguin Melatonin Gummies are one of a growing range of sleep products that use oils and melatonin to help people sleep.

An extract obtained from the plants, but which does not produce any of the mind altering or psychoactive effects that the other extracts of the plant are known for.


By doing this, it can reduce anxiety and depression and make it easier to fall asleep.

It can then even offer additional health benefits, such as treating the symptoms of epilepsy, ALS, PTSD, diabetes, and autism spectrum disorder, combatting chronic pain, preventing brain disorders, and even helping people to overcome opioid addictions (12).

The 10 mg of oils present per serving is then supported by 3 mg of melatonin, which allows it to offer further sleep benefits, while not being strong enough that the two compounds could become too much when combined.


  • Contains 3 mg of melatonin and 10 mg of oils per serving

  • Available in a choice of two great tasting varieties

  • Will benefit your sleep without causing any side effects


  • Has a small, enjoyable to take serving size


  • Contains sugar and a number of artificial flavors and colours

Natrol Liquid Melatonin - The Best Melatonin Liquid

Natrol Liquid Melatonin Sleep Support is a gluten free, vegan supplement that supplies people with around 3 mg of melatonin per serving. Natrol claim it will treat occasional sleeplessness and help you fall asleep faster, stay asleep longer, and wake up feeling totally rested.

Designed as an oil, it is a perfect option for people who either can't or don't like swallowing pills or capsules. Its natural berry flavour can make it enjoyable to consume, while still being subtle enough for people to mix it into a drink of their choice if they would prefer.


Made without the use of any artificial sweeteners or flavours, GMOs, preservatives, synthetic dyes, or known allergens, it is also suitable for use by the vast majority of people.

The only issue some people may have with it is the price. While the price per bottle looks fairly reasonable, each bottle containing just 15 servings can make it quite pricey if you use it on a regular basis.

However, if you are averse to taking pills or capsules or simply like the idea of using a liquid melatonin supplement, Natrol Liquid Melatonin is perhaps the best way to go.



  • Boasts a pleasant yet subtle berry flavour

  • An ideal melatonin supplement for people who can't or don't like swallowing capsules or pills

  • Suitable for use by people following a vegan diet


  • Can get quite pricey if used regularly, due to the minimal number of servings in each bottle

  • Does not contain any additional ingredients to support the melatonin

Relaxium Natural Sleep Aid - The Most Popular Melatonin Tablets

Relaxium Natural Sleep Aid is an immensely popular sleep aid that is designed to be non-habit forming. It claims to be able to help you fall asleep faster, stay asleep longer, and wake up feeling fresh, alert, and focused, without causing any side effects.


In addition to melatonin, the Relaxum Natural Sleep Aid formula consists of magnesium, ashwagandha, GABA, valerian root, hops extract, chamomile, and passionflower.

With the exception of chamomile, hops extract, and passionflower, all of these ingredients were present in RestAgain and do a similar job here, albeit to a lesser degree, due to the lower dosages.

Chamomile is a herbal extract known for its calming effects that is often consumed in teas. Fuelled by a chemical called apigenin, it can reduce stress and anxiety levels, help you relax, and treat issues that impair sleep quality, such as inflammation or an upset stomach (13).


Hops extract is rich in antioxidants that can reduce anxiety, depression, stress, and tension, all of which will help you to fall asleep faster, treat sleep issues like chronic insomnia, and help you achieve a healthy sleep wake cycle (14).

Passionflower extract reduces anxiety, hysteria, insomnia, and seizures. It does this by increasing your body's natural production of GABA, which will make it far easier to relax and drift off into a restful sleep (15).

There are a couple of issues I do need to mention about Relaxium Natural Sleep Aid though.

First, some of the ingredients present need to be researched more thoroughly before all of their benefits and side effects can be proven conclusively, so we don't know precisely how they will operate in the product.


It is just important that you are aware that there are more potent melatonin supplements on the market if that is your primary concern.


  • One of the most popular and widely used melatonin supplements currently on the market

  • Contains a range of ingredients beyond just melatonin that are used to offer sleep benefits

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


  • A proprietary blend masks the dosages of some of its ingredients, making it impossible to determine precisely how they will function

  • Some of the ingredients require further research before we can conclusively say that they benefit sleep


Olly Sleep Gummies - The Most Popular Melatonin Gummies

Olly Sleep Gummies are a chewable, gluten free melatonin supplement that is ideal for people who can't or don't like swallowing pills. It was created to help you relax and fall asleep, enjoy rejuvenating sleep, and wake up feeling fresh, while being very pleasant to take.

Frequently Asked Questions (FAQs) About Melatonin Supplements

What Is Melatonin?

Melatonin is a naturally occurring hormone that is produced by the pineal gland in the human brain.

Best known for improving your circadian rhythm and sleep patterns, how much melatonin you have in your system will also effect your immune system, blood pressure, and stress and inflammation levels as well.

How Do Melatonin Supplements Work?


Melatonin supplements work by either increasing the production of naturally occurring melatonin in your body or by boosting your melatonin levels with an external source of the hormone.

This will help make it easier for you to fall asleep, stay asleep, and enjoy a good quality of sleep, while also enjoying a range of additional health benefits.

Are Melatonin Supplements Safe?

Taking melatonin is usually considered safe, provided you don't take very high doses of more than 12 mg of melatonin per day.

It must be noted that, as melatonin is a hormone, it does have the potential to cause side effects when you boost your levels with an external source. These include daytime sleepiness, head and stomach aches, dizziness, nausea, dry mouth, and itchy skin.


However, all of these issues are extremely rare, provided you stick to doses of around 10 mg of melatonin per day.
