Melatonin Gummies Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Amazon Basics is the best-performing melatonin gummies brand in July 2026, moving 80,000 units across 2 ASINs for 30.8% of Top 10 volume. Natrol follows with 70,000 units (26.9%), ahead of Lemme on 30,000 units (11.5%).

With 7 brands splitting the Top 10 and 69.2% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $9.04 to $27.12, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, 2 ASINs forced its way in: B0F5W6C3PL booked 10K units at $7.99, with ▲ 0.0% MoM change. On the growth side, B09JMJ554Y leads positive momentum with ▲ 200.0% MoM growth on 3K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
