Top Melatonin Supplements of 2025

• People who work in shifts: This usually refers to people who work outside of traditional morning-to-evening schedules.* 

Who might benefit from melatonin?*

• People with occasional sleeplessness: Although melatonin is not guaranteed to make everyone fall asleep faster, some may find it beneficial for occasional sleeplessness.* 
• People who struggle to fall asleep at a conventional bedtime.*

What’s the best way to take melatonin? 

It’s a good idea to speak with your doctor or personal physician before beginning a new supplement routine. The best way to take melatonin supplements is by carefully reading the label and following the suggested instructions unless told otherwise by a healthcare professional. 

You can also support the efficacy of melatonin supplements by adopting good sleep hygiene habits, eating well, exercising regularly, and trying to reduce stress levels. Some people have also found it beneficial to combine melatonin with other ingredients that may help support better quality sleep and relaxation.* 

What are other ingredients in sleep supplements?

It’s common to find melatonin supplements that are a blend of different ingredients believed to support sleep. This includes adaptogens, amino acids, and herbal extracts. Adaptogens like valerian root or amino acids like GABA are a popular addition to many melatonin sleep supplements because they may impact the body in a different way to melatonin. This may help to promote feelings of relaxation and calm that support melatonin in helping to prepare the body and mind for better-quality slumber.

Melatonin for sleep: Does it really work?

Melatonin is a hormone that is naturally produced by the brain in response to darkness. It plays a role in sleep by helping to regulate our circadian rhythm, also known as our sleep-wake cycle or night and day cycle. The amount of melatonin increases when it gets darker and decreases the lighter it is. Melatonin doesn’t make you fall asleep but  works to promote better sleep by preparing the body for sleep.

Given its potential to support more restful sleep, it’s no wonder people have been reaching for melatonin sleep supplements increasingly more in recent years. This is especially true for those who periodically struggle to get proper shuteye.

2. Melatonin Gummies

by ZzzQuil

PROS

• Flavored gummies
• 2 mg melatonin
• Gluten-free

CONS

• Contains added sugars
• No magnesium or GABA

BOTTOM LINE

ZzzQuil's Melatonin Gummies offer a tasty, gluten-free option with 2 mg of melatonin per serving. While they're easy to take and flavored for better palatability, they contain added sugars and lack additional sleep-supporting ingredients like magnesium or GABA that some users may be looking for.

4. Relaxium Sleep

by Relaxium

PROS

• Includes melatonin, GABA, L-tryptophan 
• Contains magnesium

CONS

• 30 day money-back guarantee

BOTTOM LINE

Relaxium Sleep by Relaxium is formulated with ingredients like valerian root, GABA (Gamma-Aminobutyric Acid), and ashwagandha root. This sleep formula comes in two capsules which should be taken 30-40 minutes before bedtime. All-in-all this product is fairly similar to the number one product on this list, although you may want to note that Relaxium only offers a 30-day money-back guarantee.

GRADE

3. Natrol Melatonin

by Natrol Store

PROS

• 1-tablet serving size
• 5 mg of melatonin 
• Price

CONS

• No magnesium 
• Contains wheat and soy 

BOTTOM LINE

Natrol's Melatonin tablets deliver 5 mg of melatonin in each serving. Although these tablets are small, easy to take, and sold at a reasonable price point, they are not gluten-free as the product contains wheat. It also contains soy and therefore may not be suitable for everyone. They also only contain melatonin, making the variety of ingredients smaller than some of the other products on this list.

GRADE

5. Sleep Gummies

by OLLY

PROS

• Contains melatonin, L-theanine, and herbal extracts
• Convenient gummy form

CONS

• Contains added sugar, which may not be ideal for those watching their sugar intake
• Not suitable for vegans due to gelatin content
• Potential for overconsumption due to candy-like taste and appearance

BOTTOM LINE

OLLY Sleep Gummies offer a unique spin on traditional sleep supplements, featuring melatonin, L-theanine, and herbal extracts like chamomile and lemon balm. The recommended serving is 2 gummies 30 minutes before bed, with each bottle containing 50 gummies. 

While the gummy format and blackberry zen flavor may appeal to those who dislike pills, it's worth noting that these contain added sugar and gelatin, making them unsuitable for some dietary needs. The candy-like appearance and taste may also lead to overconsumption if not used as directed, especially if kept within arm’s length of children, which might raise safety concerns due to their candy-like appearance. 

Despite these considerations, OLLY Sleep Gummies provide a convenient option for those seeking a more palatable sleep aid.

Do you find yourself tossing and turning all night? You’re not alone. According to the Sleep Foundation, 35.2% of all adults in the U.S. say they sleep less than the recommended 7 hours per night.*[1]

Supplements affect each individual in a different way, but there are certain groups of people who may choose to take melatonin for sleep. They include:

• Unclear or Misleading Labels: The best melatonin supplement should always clearly list exactly what’s included in the formula.
• Lack of Third-Party Testing: Look for melatonin sleep supplements that have been independently third party lab tested. These unbiased test results will guarantee that the product is top quality and free from unwanted extras, such as contaminants, traces of heavy metals, or pesticides.
• Diphenhydramine:  Some generic melatonin supplements may contain an antihistamine known as diphenhydramine that’s used in allergy medications. This ingredient may leave some with a sleepy, groggy feeling the next day.
