The 6 Best Melatonin Supplements of 2023

Dosage: 1 tablet, one hour before bedtime
Melatonin per serving: 5 mg

Nature Made is one of the best vitamin supplement brands on the market, if not the best. All of its supplements are USP-verified, meaning that the products and facilities have been tested for toxins and contaminants and that the label is correct. Nature Made Melatonin tablets contain 5 mg of melatonin and 80 mg of calcium (as dibasic calcium phosphate), about only 6% of the daily recommended value of calcium. If you already take a multivitamin with calcium, this shouldn’t interfere. In addition, one tablet also contains sodium starch glycolate, magnesium stearate and croscarmellose sodium. Nature Made is free of added colors, preservatives, artificial flavors and gluten.

Take one tablet about an hour before you go to bed. One bottle will last about 90 days.

Pros:

• Nature Made supplements are always USP-verified and affordable
• One bottle is enough for 90 nights

Cons:

• May take up to an hour to kick in
• Not intended for anyone under 18 years of age

Dosage: 1 tablet at bedtime
Melatonin per serving: 5 mg

Nature’s Bounty has over 50 years of experience in the supplements industry. The company is known for being affordable and accessible. The tablets in a bottle of Nature’s Bounty’s Melatonin are double-layered, meaning that the first layer of 2.5 mg of melatonin is fast-acting. The second layer of an added 2.5 mg of melatonin is intended for extended-release. In addition to the melatonin, one tablet contains dicalcium phosphate, vegetable cellulose and less than 2% of silica, triacetin, vegetable juice color, vegetable magnesium stearate and vegetable stearic acid. Nature Bounty’s supplements are non-GMO and contain no artificial flavors, sweeteners, preservatives, sugar, starch, milk, soy, sodium, gluten, wheat, yeast or fish.

Take one tablet at bedtime. One bottle will last for about 60 nights.      

Pros:

• A great price for the amount of tablets and melatonin
• Bi-layer tablets for quick release and extended release later

Cons:

Dosage: 2 gummies, 30 minutes before bedtime
Melatonin per serving: 3 mg

Olly consistently produces great-tasting gummy vitamins. If you don’t like swallowing pills with an aftertaste, gummy supplements may be for you. Olly Sleep gummies are unique on this list because they don’t just contain melatonin. Each serving size of two gummies contains 15 calories, 3 grams of carbohydrates, 2 g of added sugar, 1 g of protein, 100 mg of L-Theanine, 3 mg of melatonin, 17 mg of chamomile extract, 17 mg of passionflower extract and 16 mg of lemon balm extract. Other ingredients include glucose syrup, beet sugar, water, gelatin, natural flavors, citric acid, coloring (from blueberry and carrot juices), pectin, vegetable oil and carnauba wax. They’re processed in a facility that makes products that may contain soy, egg, peanuts, tree nuts, milk, fish, shellfish and wheat.

The gummies are blackberry-flavored, gluten-free and contain no artificial flavors. Take two gummies 30 minutes before bed — no water or food required. One bottle contains enough for about 25 nights.   

Pros:

Cons:

• One bottle contains only enough for 25 nights 
• Lower dose of melatonin

Dosage: 1 tablet, 20 minutes before bedtime
Melatonin per serving: 10 mg

Natrol is one of the most popular melatonin brands. One bottle of Natrol contains 100 tablets, enough for 100 nights. The fast-dissolving tablets don’t require any water. One serving contains 10 mg of melatonin and other added ingredients such as dextrose, microcrystalline cellulose, cellulose gum, crospovidone, maltodextrin, glyceryl behenate, sucrose esters, gum acacia, beetroot powder, silicon dioxide, sucralose and artificial flavor. The tablets are free of milk, egg, fish, shellfish, tree nuts, peanuts, soy, yeast and preservatives. 

This is the exact melatonin supplement that I sometimes use before bed. The only reason why these supplements aren’t the best overall is that they may not be for everyone. The flavor is similar to children’s cherry cough syrup, so I make sure to always brush my teeth after taking one tablet. However, Natrol does offer another citrus flavor.

Pros:

• Only takes about 20 minutes to kick in
• No added sugar

Cons:

• Not everyone will like the flavor 
• With this high of a dose of melatonin, you have to be careful

Dosage: One capsule at bedtime
Melatonin per serving: 3 mg

The capsules are free of artificial flavors, gluten, dairy and soy.

The lower dose of 3 mg may require a second serving before bed.
