Best Protein Cereal Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
Cheerios is the best-performing protein cereal brand in July 2026, moving 70,000 units across 3 ASINs for 43.8% of Top 10 volume. purely elizabeth. follows with 30,000 units (18.8%), ahead of Catalina Crunch on 20,000 units (12.5%).
With 7 brands splitting the Top 10 and 75.0% 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 $4.35 to $6.34, which frames the price band a competing listing has to justify.

Trending Protein Cereal Products — Growth Leaders & New Top 10 Entrants
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: B07RB7KM5S booked 10K units at $5.48, with ▲ 0.0% MoM change. On the growth side, B07CM8J4NC leads positive momentum with ▲ 100.0% MoM growth on 20K units, with B08X68PTVG 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
