Pure Protein Shakes Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Core Power is the best-performing pure protein shakes brand in July 2026, moving 210,000 units across 3 ASINs for 38.2% of Top 10 volume. Premier Protein follows with 200,000 units (36.4%), ahead of Orgain on 60,000 units (10.9%).

With 5 brands splitting the Top 10 and 85.5% 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 $25.64 to $43.91, 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: B0DY1ZS88N booked 40K units at $21.99, with ▲ 0.0% MoM change. On the growth side, B0FST1C48K leads positive momentum with ▲ 150.0% MoM growth on 10K units, with B0015068TG close behind at ▲ 100.0% MoM on 20K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
