Alli Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

alli is the best-performing alli brand in July 2026, moving 14,000 units across 2 ASINs for 28.6% of Top 10 volume. Double Wood Supplements follows with 10,000 units (20.4%), ahead of Momentous on 8,000 units (16.3%).

With 9 brands splitting the Top 10 and 65.3% 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 $19.99 to $86.73, 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: B07983JXN2 booked 2K units at $13.95, with ▲ 0.0% MoM change. On the growth side, B0GV4C97SK leads positive momentum with ▲ 100.0% MoM growth on 2K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
