by Nature's Bounty

PROS

• Dissolvable tablet 
• Features 3 mg of melatonin
• 1-tablet serving size

CONS

• Can only be purchased through 3rd party retailers
• Flavored 

BOTTOM LINE

Nature’s Bounty Melatonin is a melatonin supplement that delivers 3 mg of melatonin in each quick-dissolve tablet. This product is simple and comes in a single tablet serving which is convenient to take. It’s good to note that the tablet comes in a cherry flavor as a flavored tablet may not be the most preferred way of taking a supplement for everyone. 

B

GRADE

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. 

C+

GRADE

by Natrol

PROS

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

CONS

• No magnesium 
• Contains wheat and soy 

BOTTOM LINE

Natrol’s dissolvable melatonin tablets deliver 5 mg of melatonin in each serving. While our team felt that these tablets are easy to take and liked that they are sold at an affordable price, 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 its variety of ingredients smaller than some of other products on our list.

C

GRADE

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.

CITATIONS

DISCLAIMER: This scientific research is for informational purposes only. The results reported may not necessarily occur in all individuals. Primal Harvest provides this information as a service but does not endorse it. This information should not be read to recommend or endorse any specific products.

• Unclear or Misleading Labels: A quality sleep supplement should always clearly list exactly what’s included in the formula.
• Lack of Third-Party Testing: Look for 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 sleep 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.

Note: Individual results may vary. 

• Melatonin: Melatonin is an essential sleep hormone that sends signals to your brain when it’s time to sleep, wake, and eat. Shown to help regulate your body’s internal clock (circadian rhythm), melatonin can help regulate your body temperature and other important hormones needed to fall asleep soundly.* 
• Valerian root: Valerian root has been used for centuries for its calming, sleep-promoting benefits. Research suggests that valerian may help promote the length and quality of deep, restorative sleep, as well as reduce the time it takes to fall asleep at night.* [2]
• Important Amino Acids: Amino acids like Gamma-Aminobutyric Acid (GABA) and L-Tryptophan are thought to help your body produce the proteins and molecules needed for good sleep and relaxation.* 
• Calming Herbal Extracts: Look for soothing herbal extracts like chamomile, lavender, lemon balm, and hops. They are thought to help support relaxation and calm which are important for unwinding after a long day, de-stressing, and preparing your body for sleep.*
• Magnesium: One of the most abundant minerals in your body, magnesium supports over 300 bodily processes, including sleep regulation. Magnesium supplementation has recently become a popular way to support sleep quality.*

According to the Sleep Foundation, 35.2% of American adults say they sleep less than the recommended 7 hours per night! [1]
