Best Melatonin Supplements of 2024

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.

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.

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.

Thorne is a well-known personalized supplement subscription brand. Thorne is popular with athletes because some of their supplements are NSF-certified for sport. You know what you are putting in your body from looking at the label -- no surprises. Thorne Melatonin contains 3 mg of melatonin and other ingredients including microcrystalline cellulose, hypromellose (derived from cellulose) capsule, calcium laurate and silicon dioxide. The capsules are free of artificial flavors, gluten, dairy and soy.

This vegan supplement is to be taken at bedtime. One bottle will last about 60 nights. 

Liquid supplements are great for anyone who dislikes swallowing pills or artificial flavors of gummy vitamins. Now Liquid Melatonin comes in a pack of two 2.0 fluid ounce bottles and requires about 20 drops a serving. Each bottle contains about 60 servings. The lower dose of 3 mg may require a second serving before bed. In addition to melatonin, the supplement also contains water, vegetable glycerin, fructose, xylitol (which is very harmful to pets -- keep out of reach), organic cane alcohol (6%), natural orange extract (citrus sinensis), natural flavors, potassium sorbate (as preservative), citric acid, malic acid and natural lemon oil. This liquid supplement is free of gluten, soy, milk, egg, fish or shellfish ingredients.  

At bedtime, take the drops directly, or you can add them to your favorite beverage. The flavor is citrusy, but the taste as unpleasant. Drinking something afterward is recommended.
