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

Bob's Red Mill is the best-performing protein oats brand in July 2026, moving 31,000 units across 4 ASINs for 39.2% of Top 10 volume. Quaker follows with 25,000 units (31.6%), ahead of Nature Valley on 16,000 units (20.3%).

With 4 brands splitting the Top 10 and 91.1% 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 $5.22 to $12.47, 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, 2 ASINs forced its way in: B07ZQNS2FY booked 7K units at $15.52, with ▲ 40.0% MoM change. On the growth side, B0017WE0FG leads positive momentum with ▲ 233.3% MoM growth on 3K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
