Our take
Why we pick it Lab tests have found melatonin far off the label (Erland 2017; Cohen 2023). In our view, a public testing list is the best outside check a buyer can see. 12 of the 29 melatonin products we read are on one. Two of these are sold through our links: Nature Made Melatonin 3 mg and Nature Made Melatonin 2.5 mg Gummies (USP Verified, an outside testing program; see what that checks). Each tablet has 3 mg, inside the 0.5 to 5 mg range most trials used.
What you give up A little money. At $0.051 a night it costs more than our lowest-cost pick ($0.037). No study we read tested whether listed products are more accurate. To see how much to take, read our dosage guide.

Our take
2.5 mg of melatonin a gummy for $0.18 a night, on USP Verified. Our gummy pick scores higher (10.0) because it’s compared only with other gummies; the 3 mg tablet costs less a night ($0.051). Gummies we score cost $0.18 to $0.20 a night, against $0.037 to $0.18 for tablets and capsules. Keep gummies away from children. Read about melatonin gummies.

What about 0.3 mg melatonin?
Life Extension sells 0.3 mg capsules and 0.3 mg timed-release tablets. Both score 3.5 out of 10. The reason is the dose range we score against, not proof that 0.3 mg fails. Most trials used 0.5 to 5 mg, so a 0.3 mg serving earns half the dose points, and a night counts as two pills.
The studies of 0.3 mg are small. In 12 healthy young adults, 0.3 mg raised blood melatonin to its normal night level (Zhdanova 1996). In 24 healthy older adults, 5 mg clearly raised the share of time in bed they spent asleep; 0.3 mg showed only a trend (Duffy 2022). Neither study tells us what works best for most people.
Why a testing list decides the pick
8 of the 10 melatonin products we score have 0.5 to 5 mg a serving and state it clearly, so the dose rarely separates them. What you can’t see is whether the bottle holds what the label says. Lab tests have found melatonin far off the label (Erland 2017; Cohen 2023).
In our view, a public testing list is the best outside check a buyer can see. Nature Made Melatonin 3 mg is on USP Verified. No study we read tested whether listed products are more accurate, so this is our judgment, not a proven difference. See which melatonin is on a testing list, and what the lab tests found.

We also score 4 more. Each scores lower than the pick. See the price table.
The score. Out of 10, from five checks (scores updated October 12, 2026; how we score):
- Dose, up to 3 points: a serving has 0.5 to 5 mg, the range the Cochrane jet-lag review found similarly effective (Herxheimer 2002). A 0.3 mg serving earns half. We score any dose from 0.5 to 5 mg the same; that does not mean 1 mg works as well as 3 mg. See the dosage guide.
- Testing, up to 3 points: the product is on a public testing list. A brand claim that names an outside lab earns half. “Lab tested” with no lab named earns nothing.
- Cost, up to 2 points: what a night costs (the smallest number of pills or gummies that gives at least 0.5 mg), against the cheapest pill or the cheapest gummy.
- Label, up to 1 point: the label lists the exact amount of melatonin.
- Recalls, up to 1 point: no FDA recall naming the brand in 24 months (2 years).
Not scored, and why.
- Natrol Melatonin 1 mg (180 tablets): Natrol's store no longer sells a plain 1 mg tablet. We could not find a brand list price to compare. 1 mg of melatonin a tablet, with vitamin B6 10 mg.
- Zarbee's Adult Sleep with Melatonin 3 mg Gummies (60 gummies): Zarbee's store shows no price. We could not find a brand list price to compare. 3 mg of melatonin a gummy.
- 2 more melatonin products have no brand list price we could find: their brands list them as unavailable.
What melatonin does, and what to watch for
In studies of people with sleep problems, melatonin cut the time to fall asleep by about 7 minutes (Ferracioli-Oda 2013); studies found it may help more with jet lag. See what the studies found.
Short studies found only mild side effects, such as headache and sleepiness (NIH). Read the cautions, and see how much to take.
