Nutricost Melatonin Review (2026): 240-Count Bottles, Sorted

Nutricost sells melatonin the way it sells everything: plainly, in bulk, at a low price per unit. The Nutricost Melatonin 5 mg is a swallowed tablet at a labeled 5 mg, 240 to a bottle at $9.99. The title states GMO-free and gluten-free, which is more than most value-brand titles publish. $9.99 divided by 240 is about 4.2 cents a night, and the bottle lasts eight months at one tablet nightly.

Five milligrams is above the 0.5 to 3 mg range many sleep clinicians cite as a starting point, which is why the 3 mg tablet gets the next card and why this bottle is for someone who already knows their amount. A plain tablet needs water and the lead time the label directs; if you want the no-water format, the mixed-berry fast-dissolve is two cards down. The 5 mg field across every format is ranked in our best 5 mg melatonin guide.

If you are new to melatonin, this is the Nutricost to start with. The Nutricost Melatonin 3 mg is the same 240-count bottle as our pick at 3 mg, $10.00, about 4.2 cents a night. Three milligrams sits inside the 0.5 to 3 mg range many sleep clinicians cite as a reasonable starting point, on the general principle that more is not better and higher amounts are associated with next-day grogginess.

What Nutricost does not sell is anything lower for adults in tablet form; the line bottoms out at 3 mg apart from the 1 mg Gummies (180 count, strawberry, $15.95, about 8.9 cents per gummy before serving size). A buyer who wants 300 mcg to 1 mg in a tablet should look at Carlyle, Life Extension or Pure Encapsulations in our low-dose guide.

The fast-dissolve is where Nutricost's bulk pricing shows up most clearly. The Nutricost Melatonin 5 mg Fast Dissolve states 5 mg, mixed berry, 240 tablets and GMO-free in its title. The label directs the tablet to dissolve in the mouth before bed, no water. $14.95 divided by 240 is about 6.2 cents a night.

A fast-dissolve is a sweetened, flavored tablet by nature; the title does not state the sweetener, so we do not either. It is also the only flavored adult tablet in the Nutricost line, which otherwise consists of plain tablets and capsules, and the only one directed to be taken without water. If the convenience is not worth the extra two cents a night to you, the plain 5 mg tablet above is the same amount for less.

Ten milligrams is the top of the mainstream range, and this card treats it that way. The Nutricost Melatonin 10 mg Capsules state 10 mg, 240 count, non-GMO and gluten-free. $12.95 divided by 240 is about 5.4 cents a night. The same amount comes as a plain 10 mg tablet at $10.00 for 240, about 4.2 cents, so the capsule costs about a cent a night more for the format.

One step further up the line is a 12 mg tablet (240 for $11.95), which is above the top of the mainstream range and not something we point new buyers toward. The general guidance applies to all of it; melatonin side effects covers what owners report at these amounts.

The most important thing about this product is what it is not: a starting point, or a step up to try. The Nutricost Melatonin 20 mg Capsules state 20 mg, 240 count, non-GMO and gluten-free. $13.95 divided by 240 is about 5.8 cents a night. Buyers at this amount are typically there because a clinician directed them, and that is the only circumstance in which we would point anyone here.

Everything owners report at 10 mg, grogginess and vivid dreams above all, is reported more at 20 mg. Melatonin can interact with blood thinners, immunosuppressants, blood-pressure and diabetes medication, and the case for asking a pharmacist grows with the amount. If you are reading this card without a clinician's direction, the 3 mg tablet at the top of the page is the Nutricost to buy.

Same amount, same count, same format, and a much longer record. Nature Made Melatonin 3 mg is a plain swallowed tablet, 240 to a bottle at $10.73, about 4.5 cents a night. Nutricost's 3 mg is $10.00 for 240. The difference over a year is under $3.

Nature Made also sells the 5 mg Extra Strength in a 300-count bottle ($29.97, about 10 cents a night), which is far more per night than Nutricost's 5 mg, so at 5 mg the value math flips back toward Nutricost. The full line is in the Nature Made melatonin review, and the cost field is in best cheap melatonin.

If you want a capsule from a brand with a published quality record, this is the comparison. NOW Melatonin 5 mg is 180 capsules at $12.23, about 6.8 cents a night. It costs more per night than every Nutricost tablet on this page. It also comes from one of the most transparent supplement manufacturers on Amazon, which is the entire argument.

NOW also sells the cheapest credible 3 mg capsule on the site, NOW Melatonin 3 mg at 180 veg capsules for $9.17, about 5.1 cents a night, which is the direct rival to Nutricost's 3 mg tablet for anyone who prefers a capsule. Our capsules and softgels guide ranks both.
