9 Best Sleep Supplements of 2026

Nature Made Melatonin 3 mg Tablets rank first because they combine an outside quality check with the lowest nightly cost on this list. Each tablet gives 3 mg of melatonin, and the page tells adults to take one tablet an hour before bed with water. Nature Made says USP has tested and verified the ingredients, potency and manufacturing process, which none of the other plain melatonin tablets here claim. The 120-count bottle cost $8.49 on the brand store, about $0.07 a night, and a 240-count size is also listed. The label is careful: it is for occasional sleeplessness, not for anyone under 18, and it tells buyers to see a physician for use beyond three months or if they take medication. Each tablet also contains 45 mg of calcium. Buyers who want a vegan label or a sport certification should look at Thorne instead.

Thorne Melaton-3 is the most carefully certified plain melatonin on this list. Each capsule holds 3mg of melatonin, and the only other ingredients are microcrystalline cellulose, silicon dioxide, calcium laurate and a cellulose capsule. Thorne lists it as NSF Certified for Sport, which matters for athletes who face drug testing, and as gluten, dairy and soy free and vegan. The page says to take one capsule at bedtime and pitches it at people whose sleep patterns change with travel or work. A 60-capsule bottle costs $16, about $0.27 a night, which is still cheap in absolute terms but close to four times Nature Made's nightly cost. Thorne also warns that melatonin may add to the effect of blood-thinning drugs and should be used with caution or avoided before surgery. Thorne accepts FSA and HSA funds through Truemed, which helps buyers paying with pre-tax money.

Life Extension Melatonin 300 mcg is on this list for its dose. At 300 mcg, a tenth of the 3 mg most rivals use, it suits people who want to start with the least melatonin. The page describes it as gently promoting sleep at a low dose, and each vegetarian capsule contains only melatonin, microcrystalline cellulose, a cellulose capsule and silica. The bottle holds 100 capsules, which the page lists as a 100 day supply, at a regular price of $7.50, about $0.08 a night. AutoShip takes another 10% off and ships free, though some sale prices only show after signing in. Directions say to take one capsule 30 to 60 minutes before bed and not to exceed the recommended dose. If 300 mcg is not enough, Life Extension sells 500 mcg, 1 mg, 3 mg and 10 mg versions, so you can move up without switching brands. There is no outside certification named on the page.

NOW Melatonin 3 mg Veg Capsules are the cheapest way into melatonin on this list. A 60-capsule bottle costs $6.99, and the 180-capsule bottle costs $14.99, which brings the nightly price down to about $0.08. Each capsule holds 3 mg of melatonin with rice flour and a cellulose capsule, and NOW labels the product halal, kosher, vegan, non-GMO and gluten free. The caution text is clear: adults only, at bedtime, not with alcohol or before driving, and check with a physician if you take sedatives or antidepressants. NOW also sells the same dose as lozenges and makes 1 mg and 5 mg versions for people who want to adjust. What it lacks is an outside certification on the page; NOW lists awards from Vitamin Retailer Magazine, but not a USP or NSF mark. That is why it ranks below Nature Made and Thorne on quality.

Doctor's Best Melatonin 5 mg is the chewable pick. Each natural mint tablet gives 5 mg of melatonin, and the other ingredients are mannitol, mint flavors, vegetable magnesium stearate and silicon dioxide. The page labels it non-GMO, gluten free and vegan, and says to chew one tablet at bedtime. A 120-tablet bottle costs $9.99 one-time, about $0.08 a night, and Autoship takes 5% off. That makes it as cheap per night as the 3 mg tablets above while giving a larger dose, which is not always what a buyer wants: 5 mg is more melatonin than Nature Made, Thorne or NOW use, and people who are new to melatonin may prefer to start lower. The warning text rules out use under 18, during pregnancy or nursing, and before driving. No USP or NSF mark appears on the page, so it ranks below the certified options.

Natrol Sleep & Restore is the blend for people who would otherwise buy melatonin and magnesium separately. A two-capsule serving gives 5mg of melatonin, 100mg of GABA, 100mg of magnesium as magnesium glycinate and 10mg of vitamin B6, plus a 25mg blend of tart cherry, lemon balm and chamomile extracts. Natrol says to take it 20 to 30 minutes before bed and calls itself America's number one drug-free sleep aid brand, citing Nielsen sales data for the year ending January 2025. A 30-serving bottle costs $18.99 one-time, about $0.63 a night, and Subscribe & Save cuts 15%. The trade-offs are cost and dose: it is far pricier per night than a plain melatonin tablet, the 5mg melatonin dose is higher than most rivals here, and the page does not name an outside certification. Natrol also sells a melatonin-free version of the same capsule.

OLLY Sleep is the gummy on this list, and for many buyers the format is the point. The Blackberry Zen gummies blend melatonin with L-theanine and extracts of chamomile, passionflower and lemon balm, and OLLY says they are NSF Certified, meaning independently tested for quality, safety and label claims. The jar of 25 servings costs $13.99, about $0.56 a night; a 35-serving jar costs $17.99 and the 60-serving pouch $30.99, about $0.52 a night. Subscribers save 15%, and shipping is free over $59. The product page has 1,237 reviews with a 4.2 average. We could not read the melatonin amount per serving in the page text we checked, so look at the supplement facts panel before buying if dose matters to you. OLLY also notes the gummies are not intended to treat insomnia and may cause drowsiness. Gummies cost more per night than tablets, which keeps OLLY in the lower half of this ranking.

Momentous Elite Sleep is the best-documented sleep blend on this list. A two-capsule serving combines 3mg of melatonin with 200mg of L-theanine, 300mg of valerian root extract, 200mg of tart cherry powder and 4mg of vitamin B6. Momentous says it is NSF Certified for Sport with every batch independently tested, and the page reports a Light Labs test from December 2025 covering 15 substances. It is HSA and FSA eligible and backed by a money back guarantee. The price is the drawback: $44.99 one-time for 30 servings is about $1.50 a night, though the 25% subscription brings it to $33.74. Momentous is also unusually direct about how to use it, saying it is meant for short-term support during travel, schedule changes or jet lag and is not intended for daily, long-term use because it contains melatonin. Buyers who want a nightly product without melatonin should look at Thorne Deep Sleep Complex.

Thorne Deep Sleep Complex is here for buyers who do not want melatonin. Each two-capsule serving combines 500mg of Maizinol, a young green corn leaf extract standardized to 0.2% 6-MBOA, with 200mg of L-theanine and 100mg of chamomile extract. Thorne describes Maizinol as a patented, non-hormonal botanical and pitches the product at people who struggle to fall asleep because of stress or a racing mind, or who wake during the night. The FAQ says each ingredient is tested for identity, purity and potency, including heavy metals, pesticides and microbes, and the product carries the NSF Contents Certified mark. Thorne also says it is designed to avoid morning grogginess. The cost is steep: $52 for 60 capsules is 30 servings, about $1.73 a night, the highest on this list. Thorne recommends checking with a health-care provider before combining it with melatonin or prescription drugs.
