6 Best Melatonin Supplements – CNET

Melatonin, a natural hormone in our brains, can be taken at night to help you sleep. This way, your brain will tell your body it’s time to sleep. The artificial melatonin in an added supplement mimics the natural melatonin in our brains when it gets dark. It is a natural sleep aid without a prescription.

How Much Melatonin Can Adults Take?

Typical doses of melatonin are between 1 and 5 milligrams, although some products go as high as 20 mg. Cleveland Clinic experts recommend trying 1 mg of melatonin for a full week, then increasing the dose by 1 mg every subsequent week. Discontinue once you reach 10 mg (do not exceed 10 mg) or until the time to fall asleep has decreased. Talk to your doctor about any dosing problems.

Here are the best melatonin supplements on the market.


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, which means 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), approximately only 6% of the recommended daily 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 from added dyes, preservatives, artificial flavors and gluten.

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

In addition to melatonin, one tablet contains dicalcium phosphate, vegetable cellulose and less than 2% silica, triacetin, vegetable juice dye, 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.

Dosage: 2 gummy candies, 30 minutes before bedtime

Olly consistently produces great tasting gummy vitamins. If you don’t like swallowing pills with an aftertaste, gummy supplements might be for you. Olly Sleep gummy candies are unique on this list because they don’t just contain melatonin. Each serving of two gummy candies 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 extract of passionflower 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 are processed in a facility that produces products that may contain soy, egg, peanut, tree nuts, milk, fish, shellfish and wheat.

Natrol is one of the most popular melatonin brands. One bottle of Natrol contains 100 tablets, enough for 100 nights. Fast dissolving tablets do not require 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, acacia gum, beet powder, silicon dioxide, sucralose and artificial flavor. The tablets are free from milk, egg, fish, shellfish, tree nuts, peanuts, soy, yeast and preservatives.

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


  • It only takes about 20 minutes to get into action
  • With no added sugar


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