10 Best Melatonin Supplements Fully Reviewed

last updated Jul 10, 2019
Melatonin is a hormone which is released from the pituitary gland that aids in a person’s sleep patterns. While millions of people take melatonin supplements to assist in getting better rest, it can make one tired just looking through the plethora of brands on the market today.

Sleep is also a huge factor in how our bodies better prepare for the next day’s activities. A well-rested body means a better workout or more pleasant day on the job. Furthermore, using melatonin is a more natural option for getting the rest you need versus sleeping pills and other PM supplements.

We took all this into consideration when putting together our 10 Best Melatonin Supplements list and took some of that tiresome research out of the equation so you can get on with your rest and look forward to a more productive day without feeling groggy.

Pros:

Potent

Perfect for Travel

Better option for people who do not like pills

More controlled dosage

Cons:

Flavor

More Expensive

Source Naturals Sleep Science NutraSpray is a completely different option than we have found anywhere. It gained a spot on out 10 Best Melatonin Supplements list for this as well as the fact consumers are raving about the rapidness of absorption, effectiveness, and ease of use.

In each squirt, you get 1.5 mg of melatonin, which you can obviously use more if desired. The fact you can control your intake and have another option versus not having to swallow a pill were other plus sides to why consumers are loving this melatonin supplement.

Read more

Ingredients

Besides the 1.5 mg of Melatonin per squirt we mentioned, it has B6. B6 is known for its aid in promoting more melatonin production naturally. So not only are you getting extra melatonin to boost your sleep, you are getting a healthy vitamin that allows your body to do what it naturally does. B vitamin deficiencies can create all sorts of issues in sleep rhythms and energy levels, so there really isn't any downside to the add-in.

Other ingredients include vegetable glycerin, deionized water, lecithin (soy), natural orange flavor, potassium, and benzoatelauric arginate. As you can see, there is a Soy allergy warning on the label due to t the lecithin; just a side note to be aware of.

Delivery Method

Source Naturals Sleep Science NutraSpray’s unique spray delivery gives those that don’t like pills or drops an option for a better natural sleep aid as well. You spray between one to 3 sprays of the melatonin magic in your mouth a half hour or so before you plan on going to bed and your all set. It even has a nice orange flavor, so you aren't gagging down icky medicine flavors some brands have.

Dosing Options

As we mentioned, the dose depends on you. However, Source naturals suggest no more than 3 squirts unless otherwise directed by a doctor.

Each dose or spray only gives you a 1.5 mg dosage, however, consumers are actually raving about its potency and fast absorption. Furthermore, the fact there isn't a lot more added and the B6 helps your body create even more melatonin adds to why this is a 10 best option.

Pros:

In store or online purchasing options

Low dosage

Better taste

Cons:

Less than 1 milligram per lozenge 

GNC is a trusted name in supplements and operates thousands of stores worldwide. This supplement is available not only in their store but in other retail establishments as well as online.

Read more

Additives
The only additives you will find in this melatonin lozenge are artificial sweeteners. The two that are found in this product are sorbitol and mannitol which are both sugar substitutes. While some would prefer a supplement without any artificial ingredients at all, this additive comes as a welcomed addition to some. It improves the taste of the product and makes the ingestion much more enjoyable.

Delivery Method
The GNC melatonin supplement comes in a very low dose of the lozenge. Although one of the more common ingestion methods, what sets it apart from the rest is the taste. Users commented that while some other lozenges have a difficult to bare taste, this product was rather pleasant.

Dosing Options
This product is one of the smallest dosing options on our list. It comes in a 1-milligram lozenge, but after testing, it was revealed that the purity of the product is actually slightly lower than this, at .89 milligrams per lozenge. This is a good choice for those looking for a very small amount of melatonin rather than a higher, more potent dosage.

Pros:

• Small round tablets

• Cheap for the dosage you get

Cons:

Dosage may be too potent for some people

Just Potent Melatonin is high-quality melatonin designed to help you not only sleep well but wake up without feeling groggy. The motto for the product is “No Grogginess”. Just Potent is a company that’s all about honesty and quality, two traits that show in their melatonin supplement.

Read more

Additives
This is pure melatonin. There are some minor additives on the tablets to help them act faster, but they are in such relatively small amounts that they are notes on the nutritional label.

Delivery Method
Just Potent Melatonin comes in tablets. It works pretty quickly, usually in about 45 to 60 minutes. The tablets are small, round, and easy to swallow.

Dosing Options
This is a bigger dosage them many other kinds of melatonin, with every tablet containing 10mh of melatonin and just about nothing else. This is still a safe dosage. A full tablet can be very potent for many people, so don’t hesitate to cut one in half. If you’ve found that smaller doses of melatonin haven’t been helping you, this might be the right one.

Leading name in Melatonin

 Affordable

Cons:

Higher dosage then advertised

Natrol is a leading name in vitamin and supplement productions. They have been going strong for 35 years, and one of their leading products is their melatonin supplement. They are actually one of the leading names in melatonin supplements across the country and set the standard. This product can be found online and also in most popular retailers.

Read more

Additives
One of the key additives in this product is vitamin B6. Vitamin B6 is used to support the metabolic process and promote a healthy nervous system. This product also comes with a few naturally stabilizing compounds like stearic acid and cellulose. Other than these two elements, the product is made from pure melatonin.

Delivery Method
One of the only tablets to make our list, the Natrol Melatonin slowly dissolves in the system to provide a time-release burst of melatonin. This slowly released the product into your bloodstream and stays in your system longer than other supplements.

Dosage Options
This product comes in a standard 5-milligram dose. This is at the higher end of the safe amount of melatonin suggested by professional. In addition to this, after multiple quality tests, it was determined that this product actually contains almost 7 and a half milligrams of melatonin instead of the 5 milligrams that are advertised on the bottle. This is not dangerous but it should be mentioned so that individuals don’t take more than the appropriate amount.

Cons:

Flavor

Nature’s Bounty has been supplying no-nonsense vitamins for over 40 years and they offer their Sleep Support Melatonin to the same standard. They are a trusted brand with a lot of No’s on the list to include NO GMOs and that is a plus to us.

Staying healthy starts with a good sleep and Nature’s Bounty has a couple of options to get you better rested outside of the popular quick-dissolve option. These just happen to be a fan favorite but all are highly rated.

Read more

Ingredients

As we mentioned, it isn't what is in the supplement more so than what is not. Yes, Nature’s Bounty Melatonin offers, well, Melatonin but they don't add a bunch of other ingredients that you don't need.

Vegetarian-friendly, No sugar, No Gluten, No Milk, No soy, and there are tons of other No’s on the list too. The other added ingredients are naturally sourced and are used to be more for fillers, colors, and preservatives. Like beat juice, for instance, is used for color.

The Quick-Dissolve release tablets have Crospovidone, Mannitol, Vegetable Stearic Acid, and Natural Cherry Flavors. The pill choices include Silica, Vegetable Cellulose, Vegetable Magnesium Stearate, Gelatin and are not vegetarian due to gelatin.

Delivery Method

Although Natures bounty Melatonin comes in pills and chews, consumers have enjoyed the -dissolve cherry flavored option more. It is easier to get down option and comes in a higher dose at 10 mg per tablet. It is also a great vegetarian option on the 10 Best Melatonin Supplements lineup.

Dosing Options

Natures Bounty offers their Melatonin in multiple dosages depending on consumers needs. The quick-dissolve comes in a 10 mg dose and is suggested to be taken an hour or so before you go to bed for best results.

As we mentioned, they do not contain any harmful or added ingredients that would affect the dosage and based ff pureness, you'll get a better and longer night’s sleep without all the other rubbish going into your body.

Pros:

Easy to swallow

Higher dosage 

Trusted brand

Cons:

Higher price per pill

Too high a dosage for everyone

At the very bottom of our list is a Melatonin supplement that comes in a 10-milligram dosage. This high dosage is still considered to be safe but is not for the consumer who has just started on a melatonin regiment. Puritan’s Pride is a superior brand, and their 10-milligram dosage is one that the consumer trusts and comes in a pure formula.

Read more

Additives
One of the main issues that consumers had with this product is that it contains additives that keep this product from being vegan and vegetarian. One of the additives in the product is gelatin. While this product is totally safe to be consumed, it is not the best option for those looking to steer clear from animal products.

Dosing Options
Ten milligrams is a high dosage. This shouldn’t be taken by someone just beginning a melatonin supplement regiment, but some researchers suggest that the ingestion of melatonin at this dose is not only safe but highly effective. If you have consulted a doctor and she has suggested this dosage, Puritan’s Pride is a great brand to use.

Delivery Method
This product comes in a capsule formula. This is good for individuals to have a hard time swallowing pills, but can’t stomach the taste of the lozenge. This pill is coated and goes down easily. Consumers reported that these capsules are very easy to get down, even for those with sensitive gag-reflects.

Criteria Used for Evaluation

Product Purity

Often when we hear additives, we assume that they are unnatural and bad. This is often the case, however, not all additives found in melatonin supplements are bad.  Since melatonin is best known as a sleep aid, some products will include a sleeping aid additive in their product, which may upset your natural sleep cycle and can actually be habit forming.  Another additive to stay away from is any filler ingredient.

Application

We looked at products that only offer a safe amount of melatonin. The highest dose we went up to is 10 milligrams. Even this is high, according to studies, and should only be taken for a short period of time. We wanted to provide a variety of dosing options, within the realm of safety to ensure that everyone has access to an option that works best for them. Most professionals agree that a safe dose is anywhere from 1 to 5 milligrams.

Use

There are three main ingestion methods for a melatonin supplement and each has its own pros and cons depending on the needs of the individual. 

One of the common ingestion methods for melatonin supplements is a lozenge. This is similar to a cough drop. The user places it against their cheek or under the tongue and it slowly dissolves. This helps the supplement enter the bloodstream quicker.

Another method is a gel capsule. This is the slowest ingestion method. In general, the cap is made from a veggie combination. Consumers should look carefully at the ingredient list to be sure the capsule material is natural.

The liquid option is less popular but is the fastest way to get the melatonin into your system. It can be taken straight or add it to a drink of your choice.

Value

There is no reason to purchase a product outside of your budget when there are so many to choose from. To determine the best value we looked at the cost per serving. We also looked at the overall quality of the product.

Type of sleep

Melatonin will help you fall asleep but isn't necessarily going to ensure you maintain that sleep.

Don't rely completely

You really want to be using these supplements sparingly, like for jetlag or a bout of sleeplessness, but moderation is best.

Other Factors to Consider

Portability

It is important to note that a melatonin supplement is not a quick fix for sleeping problems. Taking a low dosage melatonin supplement is one treatment, but other treatments should also be explored, especially if the issue persists. It is always best to consult a doctor before starting any supplement or vitamin regiment.

Brand

Two things that you should think about in terms of purchasing options is the volume and where you can buy this product. In terms of volume, not all brands offer a bulk option. Some brands offer different sizing options, but some do not. Likewise, it is important to think about where this product can be purchased. Some of the brands on our list can be found at local stores, while others can only be purchased through the internet.

Frequently Asked Questions

q: What is melatonin?

a:

Melatonin is a hormone that is naturally produced in the body. It is made in the pineal gland which is found at the base of the brain. It is released by the brain to help the body control its natural circadian rhythm. Basically what that means is that melatonin helps the body go to bed when it gets dark and wake up when it gets light outside again. Once the brain produces the melatonin, it is carried by the circulation system from the brain to other parts of the body.

When the body produces more melatonin at night, it is sending the message to the rest of the body that it is time for sleep. Although melatonin has not been proven to be necessary for sleep, it is clear that we sleep better when more melatonin is secreted from the brain and circulated throughout our systems.

q: Can I take Melatonin while pregnant?

a:

If you are using the essential oils unless it is recommended by your doctor or a physician absolutely not.    If you are planning on taking the supplement pills, make sure to ask your doctor before. It is not recommended for ppregnant or breastfeeding women to take these supplements.

In a recent study performed by the Cochrane review, it found that taking small amounts of melatonin can help get your circadian rhythm back to normal.  Other reasons why certain people may take melatonin include an individual with a disruptive work cycle which interferes with the natural sleep cycle, individuals who are blind or seeing impaired and those who suffer from ADHD.

q: I’ve never taken a melatonin supplement. How much should I start off with?

a:

Medical research suggests starting with a very low dosage initially.  A dose of .5 milligrams is a good starting point. If you are struggling to find a dose in that small of an amount it is safe to cut a pill in half.

q: Are there any side effects I should expect?

a:

Since melatonin supplements are designed to impact your sleep cycle, the most common side effects are dizziness, daytime sleepiness, and headaches. In small instances, more severe side effects were noted. It is very important to do your own research and talk to your doctor before starting any new supplement routines.

q: I noticed that some of the melatonin supplements come with added vitamins. Is this safe?

a:

Yes. It is 100 percent safe, but it is something to consider. Are you looking for the added benefits that these particular vitamins provide, or are you looking to consume a product that is just a melatonin supplement? Just because it is safe, does not mean that it is the product for you.
