What is the cheapest melatonin?
Carlyle Melatonin 1 mg, at $0.037 a night, is the cheapest of the 10 we score. It has 1 mg a tablet. Our pick, Nature Made Melatonin 3 mg, costs $0.051 a night, about $0.42 more a month, and is USP Verified. Lab tests have found melatonin far off the label, so we pick the one on a testing list. See what the tests found.
Tablets or gummies?
Gummies cost more. 5 of the 6 tablets and capsules we score cost less a night than any gummy. The gummies we score cost $0.18 to $0.20 a night, about 5 times the cheapest tablet. Keep gummies away from children. Read about melatonin gummies.
Why a night, not per mg?
Price per mg makes high-dose pills look cheapest. But for jet lag, doses above 5 mg were no more effective (Herxheimer 2002). So we price a night instead. A night is the smallest number of pills or gummies that gives at least 0.5 mg, the low end of the range most trials used. A 0.3 mg pill counts as two, so its night costs twice one pill. None of the 10 we score has more than 5 mg a serving. See how much melatonin to take.
Amazon’s price can differ from the list prices here.
Not scored: 4 more melatonin products have no brand list price we could find. The brand’s store shows no price or lists them as unavailable, so we can’t say what a night costs. See the reasons.
12 of the 29 melatonin products we read are on a public testing list. Two of these are sold through our links: Nature Made Melatonin 3 mg and Nature Made Melatonin 2.5 mg Gummies.
