Source Naturals Melatonin Review (2026): Lozenges, Time Release, Spray

The lozenge is Source Naturals' format, and 2.5 mg is the right place to meet it. The Source Naturals Melatonin 2.5 mg Orange Lozenges state 2.5 mg, orange flavor and 120 count. A lozenge dissolves in the mouth, which is the same no-water convenience as a fast-dissolve tablet; the label directs use before bed. $12.49 divided by 120 is about 10 cents a night, and the 240 count at $22.75 brings that to about 9.5 cents.

The benchmark at the bottom of this page is the one to weigh it against: NOW's 3 mg chewable lozenge is 90 for $4.88, about 5.4 cents a night, from a manufacturer with a published quality record. Source Naturals answers with a lower amount, a stated orange flavor, and a bigger bottle. Our best melatonin lozenges guide ranks the whole format, and best low-dose melatonin covers the amounts below 3 mg across every form.

Low amount, no water, vegan, ten months: this bottle checks the boxes value brands usually miss. The Source Naturals Sleep Science Melatonin 1 mg Vegan Lozenges state 1 mg, vegan and 300 count. $17.85 divided by 300 is about 6 cents a night. One milligram is inside the range many clinicians cite as a starting point and is the amount seniors, for whom lower amounts are often favored, tend to land on.

The Sleep Science line also has a 5 mg vegan lozenge (200 count, $37.28, about 18.6 cents a night), which is the line's priciest product per night and a high amount for a lozenge; the 2.5 mg orange lozenge above is the better middle step. Vegan across formats is covered in best vegan melatonin.

Same amount, same positioning, as the category's best-known time release. The Source Naturals Time Released Melatonin 3 mg states 3 mg and 120 tablets. Time-release products are marketed for people whose problem is waking in the night rather than getting to sleep; we say marketed deliberately, because that is the label's positioning and not a proven outcome. $14.63 divided by 120 is about 12 cents a night, and the 240 count at $25.96 is about 11 cents.

A time-release tablet is swallowed with water and needs the lead time a label directs; if your issue is the front end of the night, the lozenges above are the Source Naturals built for that. Time-release vs immediate-release argues the distinction in full.

Slow release at a lower amount than the category leader offers. The Source Naturals Sleep Science Melatonin 2 mg Time Release states 2 mg and 120 tablets. $11.99 divided by 120 is about 10 cents a night. The positioning is the same as every time release: marketed for staying asleep, a swallowed tablet, formulated to release over several hours.

Grogginess is the complaint that a lower slow-release amount is meant to address, and melatonin hangover and grogginess covers what owners report across amounts and formats. Seniors, for whom lower amounts are often favored, are the buyers this tablet is most obviously for; best melatonin for seniors ranks it alongside the low-dose lozenges.

A spray delivers a measured amount without a pill, and Source Naturals' is a low one. The Source Naturals Sleep Science Melatonin NutraSpray states 1.5 mg and 2 fl oz. The number of servings per bottle is not in the title, so we cannot compute a cost per night from $10.15, and the label's direction on sprays per serving is on the bottle.

The spray field is thin on recognized brands, which is part of why this one earns a card: most melatonin sprays on Amazon come from labels we do not list. At 1.5 mg it is also the lowest-amount spray we cover, which suits the general guidance to start low. Melatonin spray vs pills lays out the format trade-offs.

If the lozenge format is what you want and the price is what you care about, this is the bottle. NOW Melatonin 3 mg Chewable Lozenges state 3 mg and 90 count. $4.88 divided by 90 is about 5.4 cents a night. Source Naturals' 2.5 mg orange lozenge is about 10 cents. Same format, a comparable amount, half the price, and NOW's quality programs are among the most openly published in the category.

NOW's wider melatonin line, from a 1 mg tablet through veg capsules to a 20 mg ceiling, is in the NOW melatonin review, and the lozenge format is ranked in best melatonin lozenges.

The slow-release tablet everything else in the format is measured against. Natrol Melatonin 3 mg Time Release states 3 mg and 100 tablets. $10.83 divided by 100 is about 11 cents a night. It is a swallowed tablet formulated to release over several hours, marketed for staying asleep, which is the same positioning as the two Source Naturals time-release tablets above.

Every slow-release product from a recognized brand is ranked in best time-release melatonin.
