Slate Protein Drink Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Core Power is the best-performing slate protein drink brand in July 2026, moving 210,000 units across 3 ASINs for 44.7% of Top 10 volume. Premier Protein follows with 100,000 units (21.3%), ahead of Orgain on 40,000 units (8.5%).

With 7 brands splitting the Top 10 and 74.5% 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 $27.98 to $45.23, 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, one ASIN forced its way in: B0015068TG booked 20K units at $15.16, with ▲ 100.0% MoM change. On the growth side, B0FRB4CWHD leads positive momentum with ▲ 350.0% MoM growth on 9K units, with B0FST1C48K close behind at ▲ 150.0% MoM on 10K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
