Best Legion Protein Powder Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
vital proteins is the best-performing legion protein powder brand in July 2026, moving 90,000 units across 1 ASIN for 36.0% of Top 10 volume. Optimum Nutrition follows with 30,000 units (12.0%), ahead of Premier Protein on 30,000 units (12.0%).
With 9 brands splitting the Top 10 and 60.0% 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 $27.57 to $49.75, which frames the price band a competing listing has to justify.

Trending Legion Protein Powder 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. On the growth side, B06ZZ3PJQD leads positive momentum with ▲ 200.0% MoM growth on 30K units, with B099J2SWXV 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
