Cheapest Melatonin Per Night (2026), Ranked, With the Math Shown

Per night, from a household brand, Nature's Bounty Melatonin 1 mg, 180 tablets for $4.09, about 2.3 cents (verified via the Amazon Creators API on September 5, 2026). For 3 mg, Amazon Basics Melatonin 3 mg vegan, 260 tablets for $7.55, about 2.9 cents, is our pick. For 10 mg, Horbäach 10 mg Quick Release Capsules, 140 for $3.99, about 2.9 cents. We compute cost per night only where the title states the count.

The molecule is the same at every price; what differs is format (a plain tablet is cheap to make, a gummy is not) and transparency (house labels and value brands publish less about manufacturing than Nature Made or NOW). A 2017 published analysis found melatonin content varying widely from the label across the products it sampled, which is the one reason to pay a pharmacy brand's premium. We do not make efficacy comparisons; every product here is from a seller with a name to protect.

On this page, 2 to 5 cents for a plain tablet or capsule from an accountable seller. Fast-dissolves from major brands run about 8 to 13 cents, gummies about 9 to 24 cents per gummy before serving size, and practitioner brands 20 to 65 cents. The math on every card is price divided by the count in the title; redo it with today's price, since prices move and this ranking is a snapshot of September 5, 2026.

In the catalog, Piping Rock Melatonin Gummies 10 mg, 70 for $4.44, about 6.3 cents per gummy, from a value brand. From a house label, Amazon Basics 5 mg gummies, 120 for $10.35, about 8.6 cents. From a pharmacy brand, Nature Made 2.5 mg gummies, 130 for $13.96, about 11 cents. Gummies commonly deliver their labeled amount per two-gummy serving, so read the serving size before comparing per night. Our best melatonin gummies guide ranks the field.

It is Amazon's house label, formerly sold as Solimo and Amazon Elements, which gives it seller accountability an anonymous private label does not have, and less manufacturing transparency than Nature Made or NOW. The 3 mg vegan tablet (260 for $7.55, about 2.9 cents a night) is our cheap pick because it states the amount, the count and vegan in the title and comes from a seller with a name to protect. Our Amazon Basics melatonin review covers the whole house line.

Because a plain melatonin tablet is a tiny amount of one inexpensive ingredient with no flavor, coating or gummy matrix, and because value brands compete on count. The cheapest listings of all come from sellers with no name to protect, and those are not on this page; in a supplement, the seller's word is the only thing you are buying. We also exclude any listing whose title does not state a count, since a cheap sticker with no count is not a known price per night.

Every bottle carries a best-by date regardless of price, and a 240 or 300-count bottle at one tablet a night is an eight to ten month commitment, so check the date before buying bulk. Owners consistently report that heat and a steamy bathroom are what degrade tablets and gummies, not the price. Our explainer on whether melatonin expires covers what the dates mean.
