Buy Natrol Melatonin 3 mg Time Release, 100 tablets for $10.83 (verified via the Amazon Creators API on September 5, 2026). Immediate-release melatonin is about falling asleep; time-release is marketed for staying asleep, and Natrol's 3 mg is the most established tablet in that lane at a moderate amount. Six more picks below cover the value tablet, a 4-hour sustained release, 10 mg, two low-amount timed releases and a dual-phase capsule.

Buy Natrol Melatonin 3 mg Time Release, 100 tablets at $10.83 (verified via the Amazon Creators API on September 5, 2026). It is a labeled 3 mg formulated to release over several hours rather than at once, from the brand that has sold this format the longest, at about 11 cents a night. If you want the cheapest credible option, Nature Made 4 mg Extended Release is 90 for $7.69. If you want a lower amount spread over the night, Life Extension's 6 Hour Timed Release line starts at 300 mcg.
Here is the distinction this whole page turns on. Immediate-release melatonin, whether a fast-dissolve or a plain tablet, delivers its amount at once and is about falling asleep. Time-release (also sold as extended, sustained, prolonged or timed release) is formulated to release the same amount over hours, and it is marketed for staying asleep, for people whose problem is waking at 3 a.m. rather than getting to sleep at 11. We say marketed because that is the label's positioning; it is not a proven outcome, and owners who mostly struggle to fall asleep frequently report preferring the immediate-release tablet.
Every product here is a recognized brand (Natrol, Nature Made, NOW, Life Extension, Nature's Bounty), every fact comes from the Amazon listing title or the Supplement Facts panel, and every price was verified live on September 5, 2026. We are a verification desk, not a lab; we read labels, verify listings and weigh consistent owner reports, and we never claim to have tested a release profile. No brand paid for a placement. If you buy through our links we may earn a commission at no cost to you. Melatonin is a dietary supplement; a doctor or pharmacist decides whether it belongs in your routine.
The short version
- Our Pick: Natrol Melatonin 3 mg Time Release, 100 tablets, $10.83, about 11 cents a night. The established time-release tablet at a moderate amount.
- Best value: Nature Made Melatonin 4 mg Extended Release, 90 tablets, $7.69, about 8.5 cents a night from a pharmacy brand.
- Best 5 mg: NOW Melatonin 5 mg Sustained Release, 120 tablets, $9.17, formulated for a 4-hour release period per its title. Best 10 mg: Natrol 10 mg Time Release, 100 tablets, $16.59.
- Lowest amounts: Life Extension 6 Hour Timed Release 750 mcg ($6.00) and the dual-phase Life Extension IR/XR 1.5 mg (60 capsules, $9.00). Budget bi-layer: Nature's Bounty Dual Spectrum 5 mg, 60 tablets, $5.99.
- Time-release is not a lower amount. A 4 mg extended-release tablet is the same order of melatonin as a 4 mg immediate release, spread over more hours; the general guidance to start low applies to both.

Seven time-release melatonin products. Amount, release description and count are from the Amazon listing title; prices are live figures verified via the Creators API on September 5, 2026. Cost per night is price divided by count where the count is published.
Natrol Melatonin 3 mg Time Release, 100 Tablets
Natrol
The established time-release tablet, a moderate 3 mg, about 11 cents a night.
Our verdict: The time-release tablet most people should start with. A labeled 3 mg, inside the range many clinicians cite as a starting point, formulated to release over several hours, from the brand that has sold this format longest. $10.83 for 100 is about 11 cents a night. Buy it for the release profile, not for a higher amount.
Verified: Labeled 3 mg melatonin per time-release tablet, 100 count, described as a nighttime sleep aid in the listing title. Live at $10.83 on Amazon, verified via the Creators API on September 5, 2026.
The category's reference product. The Natrol Melatonin 3 mg Time Release states 3 mg, time release, and 100 tablets, and the title describes it as a nighttime sleep aid. It is a swallowed tablet, so it needs water and, per typical labels, a half hour or so before bed.
Natrol also sells this format at 10 mg and as Time Release 3 mg Gummies (65 count, $14.49), and a Melatonin + 5-HTP Time Release bi-layer tablet for people who want the combination. The brand is reviewed in the Natrol melatonin review, and the release question is argued in full in time-release vs immediate-release melatonin.
Who should buy it
Buy it if your issue is waking during the night rather than falling asleep, you want a moderate 3 mg, and you want the time-release tablet with the longest track record.
What we don't like
Time release is a marketing positioning rather than a guaranteed outcome, the tablet needs water and lead time, and owners who mainly struggle to fall asleep often report preferring Natrol's immediate-release fast-dissolve instead.

Nature Made Melatonin 4 mg Extended Release, 90 Tablets
Nature Made
A pharmacy-brand 4 mg extended release at about 8.5 cents a night.
Our verdict: The cheapest extended-release tablet from a recognized brand. Nature Made states 4 mg, extended release, 90 count, at $7.69, about 8.5 cents a night, undercutting our Natrol pick by a quarter at a slightly higher labeled amount. Pharmacy-shelf accountability at the value price.
Verified: Labeled 4 mg melatonin per extended-release tablet, 90 count. Live at $7.69 on Amazon, verified via the Creators API on September 5, 2026.
Same idea, pharmacy brand, lower price. The Nature Made Melatonin 4 mg Extended Release states 4 mg and 90 tablets at $7.69, about 8.5 cents a night. "Extended release" is Nature Made's term for the same slow-release positioning Natrol calls time release.
Nature Made's immediate-release line, the 3 mg tablet in particular, is the brand's best value and the pick in our best melatonin tablets guide. The whole line is in the Nature Made melatonin review, and the brand-versus-brand call is Natrol vs Nature Made.
Who should buy it
Buy it if you want an extended-release tablet from a pharmacy-shelf brand at the lowest price per night on this page, and 4 mg is an acceptable amount.
What we don't like
Extended release is a positioning rather than a proven result, 4 mg is above the commonly cited starting range, and the title states nothing about inactive ingredients.

Worth noting

- Above the commonly cited starting range
NOW Melatonin 5 mg Sustained Release, 120 Tablets
NOW Foods
NOW's 5 mg formulated for a 4-hour release, the only title here that states a window.
Our verdict: The one product on this page whose title states a release window: NOW says its 5 mg Sustained Release is formulated for a 4-hour release period. That is NOW's claim, not our measurement, but it is more than any competitor puts in writing. $9.17 for 120 is about 7.6 cents a night, from a manufacturer with a long-published quality program.
Verified: Labeled 5 mg melatonin per sustained-release tablet, formulated for a 4-hour release period per the listing title, 120 count. Live at $9.17 on Amazon, verified via the Creators API on September 5, 2026.
A stated window is worth something. The NOW Melatonin 5 mg Sustained Release states 5 mg, 120 tablets, and that it is formulated for a 4-hour release period. Every other title on this page says only "time release" or "extended release" and leaves the duration to the imagination.
At about 7.6 cents a night it is also the cheapest per night among the recognized-brand tablets here. The 5 mg amount is above the commonly cited starting range, and next-day grogginess is reported more often with slow-release products at higher amounts, so this is the bottle for someone who has already used 5 mg. NOW's immediate-release capsules are the pick in our capsules guide, and the brand is reviewed in the NOW melatonin review.
Who should buy it
Buy it if you want a sustained-release tablet at 5 mg from a manufacturer that states its release window, and you value NOW's published quality program.
What we don't like
The 4-hour window is the maker's claim and unverified by us, 5 mg is above the commonly cited starting range, and the tablet needs water and lead time.

- About 7.6 cents a night
- Manufacturer with a long-published quality program
Worth noting

Natrol Melatonin 10 mg Time Release, 100 Tablets
Natrol
Natrol's time-release at the top of the range, 100 tablets, about 17 cents a night.
Our verdict: If you have already used 10 mg and you want it slow-release, this is the credible bottle. Natrol states 10 mg, time release, 100 tablets, at $16.59, about 17 cents a night. It is the top of the mainstream range, and a slow-release 10 mg is the combination owners most often associate with next-morning grogginess, which is why it is the last amount we would suggest starting at.
Verified: Labeled 10 mg melatonin per time-release tablet, 100 count, described as a nighttime sleep aid. Live at $16.59 on Amazon, verified via the Creators API on September 5, 2026.
The top of the time-release shelf, stated plainly. The Natrol Melatonin 10 mg Time Release states 10 mg, time release, 100 tablets, nighttime sleep aid. It is the same format as our 3 mg pick at more than three times the amount.
Natrol also sells Time Release 10 mg Gummies (55 count, $16.99) for gummy loyalists. Every 10 mg format, immediate and slow release, is ranked in our best 10 mg melatonin guide, and the case for and against going higher is in best high-dose melatonin.
Who should buy it
Buy it if 10 mg is an amount you have used and tolerated, waking in the night is your specific issue, and you want the slow-release format from the brand with the longest record in it.
What we don't like
10 mg slow release is the combination owners most associate with grogginess the next morning, about 17 cents a night is the most expensive tablet here, and the general guidance favors starting much lower.

- 100-count bottle
- Gummy version in the same line
Worth noting
- Top of the range in a slow-release format
- Most expensive tablet on the page
Life Extension Melatonin 6 Hour Timed Release, 750 mcg
Life Extension
Three-quarters of a milligram spread over a stated six hours, for six dollars.
Our verdict: The product for anyone who wants the slow-release idea at a genuinely low amount. Life Extension states 750 mcg and a 6 Hour Timed Release, the most specific release description on this page after NOW's, at $6.00. The title does not state the count, so we cannot give you a cost per night; the amount is inside the low end of the commonly cited starting range.
Verified: Labeled 750 mcg (0.75 mg) melatonin per 6 Hour Timed Release tablet per the listing title; count not published in the title. Live at $6.00 on Amazon, verified via the Creators API on September 5, 2026.
Low amount, long window. The Life Extension Melatonin 6 Hour Timed Release, 750 mcg states 0.75 mg in an extended-release formula the title describes as gentle sleep support. That six-hour figure is Life Extension's formulation claim, not our measurement.
The same formula exists at 300 mcg ($9.00) for an even smaller amount. Neither title states the count, so we do not compute cost per night for either; the bottle does. Life Extension's immediate-release ladder (300 mcg, 500 mcg, 1 mg, 3 mg) is ranked in our best low-dose melatonin guide, and the brand is reviewed in the Life Extension melatonin review.
Who should buy it
Buy it if you want slow-release coverage at a low amount, you have found higher time-release tablets leave you groggy, or you are a senior or anyone for whom lower amounts are favored.
What we don't like
The title does not state the count, so the cost per night is unknowable from the listing, the six-hour window is the maker's claim, and 0.75 mg will feel like nothing to a 10 mg user.

Life Extension Melatonin IR/XR 1.5 mg, 60 Capsules
Life Extension
Immediate plus extended release in one 1.5 mg capsule, 60 count, 15 cents a night.
Our verdict: The product for people who want both halves of the argument: an immediate-release portion for falling asleep and an extended-release portion marketed for staying asleep, in one 1.5 mg capsule. $9.00 for 60 is about 15 cents a night, and 1.5 mg is a moderate-to-low total. It is the most thoughtful design on the page.
Verified: Labeled 1.5 mg melatonin per capsule, immediate-release and extended-release combined per the IR/XR name, 60 count. Live at $9.00 on Amazon, verified via the Creators API on September 5, 2026.
IR plus XR, in a capsule, at a sensible total. Life Extension Melatonin IR/XR 1.5 mg states 1.5 mg and 60 capsules. The IR/XR name denotes an immediate-release and an extended-release component; the split between them is not published in the title.
Life Extension also sells a 120-capsule IR/XR whose title describes an immediate and 7-hour extended release, at $17.75. Both release descriptions are Life Extension's claims. The brand's whole line is in the Life Extension melatonin review, and the practitioner-brand comparison is Life Extension vs Pure Encapsulations.
Who should buy it
Buy it if your problem is both falling asleep and staying asleep, you want a moderate total amount, and you prefer a capsule to a tablet.
What we don't like
The immediate-to-extended split is not published in the title, 60 capsules is a two-month bottle, and about 15 cents a night is more than the single-phase tablets above.

- Two-month bottle
Nature's Bounty Melatonin 5 mg Dual Spectrum, 60 Bi-Layer Tablets
Nature's Bounty
A bi-layer 5 mg from a household brand for $5.99, about 10 cents a night.
Our verdict: The cheapest sticker price on the page and a household brand. Nature's Bounty Dual Spectrum states 5 mg in a bi-layer tablet, 60 count, at $5.99, about 10 cents a night. Bi-layer is the brand's two-phase design; the split is not published. It is the budget way to try a dual-phase tablet.
Verified: Labeled 5 mg melatonin per bi-layer tablet, 60 count, sold as Dual Spectrum. Live at $5.99 on Amazon, verified via the Creators API on September 5, 2026.
Two layers, six dollars. The Nature's Bounty Melatonin 5 mg Dual Spectrum states 5 mg, 60 bi-layer tablets, at $5.99. Bi-layer tablets are the pressed-tablet version of the dual-phase idea, one layer for now and one for later; how the 5 mg divides between layers is not published in the title.
Nature's Bounty also makes a three-layer version, Sleep3 Melatonin 10 mg, 60 Tri-Layered Tablets at $17.98, and a 30-count Sleep3 at $9.19, both at 10 mg. The brand is reviewed in the Nature's Bounty melatonin review.
Who should buy it
Buy it if you want to try a two-phase tablet at the lowest price on the page, 5 mg is an amount you have used, and a household brand is enough accountability for you.
What we don't like
The layer split is not published, 5 mg is above the commonly cited starting range, and 60 tablets is a two-month bottle.

How we chose
Time-release products are ranked on the site's standard protocol: melatonin per serving as labeled, the release description exactly as the title states it (time, extended, sustained, timed, bi-layer, IR/XR), what else is in the formula, the count, the cost per night and the honesty of the listing. We read the Supplement Facts panel and the live Amazon listing and verify price and availability through the Amazon Creators API (this page: September 5, 2026). We weigh consistent owner reports and we do not run a lab; in particular, we have not measured any product's release curve and we do not present a maker's release claim as our finding. Pick slots go to recognized brands.
Melatonin is a dietary supplement in the United States. These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease. Time-release melatonin is marketed for staying asleep; that is the label's positioning and not a proven outcome. We report what labels direct and the general guidance many clinicians cite that lower amounts, often 0.5 to 3 mg, are a sensible starting point; we do not prescribe an amount. Melatonin can interact with blood thinners, immunosuppressants, blood-pressure and diabetes medication; ask a pharmacist. Do not drive after taking it. Next-day grogginess is the common complaint at higher amounts and is reported more often with slow-release formats. If pregnant or nursing, consult a doctor.
Questions, answered
What is the best time-release melatonin?
Natrol Melatonin 3 mg Time Release, 100 tablets at $10.83 (verified via the Amazon Creators API on September 5, 2026), about 11 cents a night. It is a moderate amount from the brand with the longest record in the format. The best value is Nature Made Melatonin 4 mg Extended Release, 90 for $7.69, and the only title that states a release window is NOW Melatonin 5 mg Sustained Release, formulated for a 4-hour release period per NOW.
What is the difference between time-release and regular melatonin?
Regular (immediate-release) melatonin delivers its amount at once and is about falling asleep. Time-release (also extended, sustained, prolonged or timed release) is formulated to release the same amount over hours and is marketed for staying asleep, for people who wake in the night. We say marketed because it is the label's positioning rather than a proven outcome. Owners whose main problem is falling asleep often report preferring immediate release. Time-release vs immediate-release melatonin has the full comparison.
Is time-release melatonin better for staying asleep?
It is the product marketed for that, and the consistent owner testimony is that people who wake in the night are the ones who keep buying it. We have not measured any product's release curve and we do not claim it works as marketed. The most specific release statements on this page are NOW's 4-hour formulation and Life Extension's 6-hour and 7-hour formulations, all of which are the makers' claims.
Does time-release melatonin cause more grogginess?
Next-day grogginess is reported more often with slow-release formats at higher amounts, and a 10 mg time-release tablet is the combination owners most often describe as leaving them foggy. The general guidance many clinicians cite, to start with the lowest effective amount, applies with extra force to a product designed to keep delivering melatonin for hours. Do not drive after taking it. Our explainer on melatonin hangover and grogginess covers the commonly cited cautions.
What is the lowest dose time-release melatonin?
Life Extension Melatonin 6 Hour Timed Release at 300 mcg ($9.00) and 750 mcg ($6.00), neither of which states a count in the title. The dual-phase Life Extension IR/XR 1.5 mg (60 capsules, $9.00) is the lowest-amount product on this page with a published count. All of these sit at or inside the low end of the range many clinicians cite as a starting point.
Can I cut a time-release melatonin tablet in half?
Generally no. Splitting an extended-release or bi-layer tablet breaks the structure that controls the release, which defeats the point. The label is the authority. If you want a smaller amount in a slow-release form, buy it: Life Extension's 300 mcg and 750 mcg 6 Hour formulas exist for exactly that reason.
Are there time-release melatonin gummies?
Natrol sells Time Release 3 mg Gummies (65 count, $14.49) and Time Release 10 mg Gummies (55 count, $16.99). They carry the same slow-release positioning as the tablets, with the usual gummy caveats: sweetened, serving size on the label, and store them away from children. Our best melatonin gummies guide covers the gummy field.
