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

Pure Protein is the best-performing protein bars brand in July 2026, moving 60,000 units across 2 ASINs for 26.1% of Top 10 volume. Quest follows with 50,000 units (21.7%), ahead of ALOHA on 30,000 units (13.0%).

With 8 brands splitting the Top 10 and 60.9% 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 $16.95 to $26.42, 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: B096H8LPP2 booked 20K units at $6.49, with ▲ 100.0% MoM change. On the growth side, B09PYB4MQS leads positive momentum with ▲ 3233.3% MoM growth on 10K units, with B0BMS16JLR close behind at ▲ 33.3% MoM on 8K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
