Glp1 Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Metamucil is the best-performing glp1 brand in July 2026, moving 130,000 units across 3 ASINs for 45.0% of Top 10 volume. Physician's CHOICE follows with 50,000 units (17.3%), ahead of Seed on 40,000 units (13.8%).

With 7 brands splitting the Top 10 and 76.1% 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 $20.47 to $59.99, 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. On the growth side, B0G3C66DHS leads positive momentum with ▲ 200.0% MoM growth on 3K units, with B001TH7K0G close behind at ▲ 100.0% MoM on 40K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
