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

Premier Protein is the best-performing protein shakes brand in July 2026, moving 200,000 units across 4 ASINs for 37.0% of Top 10 volume. Core Power follows with 110,000 units (20.4%), ahead of Orgain on 100,000 units (18.5%).

With 5 brands splitting the Top 10 and 75.9% 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 $24.65 to $50.88, 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: B01DDIRE2W booked 40K units at $59.88, with ▲ 0.0% MoM change. On the growth side, B06ZZ3PJQD leads positive momentum with ▲ 200.0% MoM growth on 30K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
