Pros:

• Inexpensive

• Designed to work with other supplements

• Easy to split in half

Cons:

• Not vegan-friendly

• Contains additives for athletes; not pure melatonin

Optimum Nutrition is a company that produces a wide range of fitness and health supplements. This is a great option or athletes especially since the dosage is designed to help them establish consistent sleep schedules in order to better facilitate recovery and health. Optimum Nutrition Melatonin is pretty expensive, especially for a supplement that has been optimized for athletes.

Read more

Additives
Besides melatonin, every tablet includes calcium and phosphorus. This is a melatonin supplement designed to facilitate athletic recovery and be taken with other supplements from Optimum Nutrition, so it doesn't have anything like sweeteners added in. It does have some milk products, meaning that this is not a vegan-friendly melatonin. The company is known for their high-quality products and this meets their high standards.

Delivery Method
This melatonin supplement comes in the form of small tablets. It acts within 30 minutes for most people.

Dosing Options
Every tablet is 3mg. This is a very safe dosing recommendation. Many people, however, may want to start out with half a tablet per dose in order to get a feel for how much you need.

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 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:

• Large dosage

• 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.

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.

Pros:

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 keeps 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 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 their 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 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 pregnant 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 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.
