Best Mk Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
Nutricost is the best-performing mk brand in July 2026, moving 10,000 units across 1 ASIN for 31.6% of Top 10 volume. NOW follows with 7,000 units (22.2%), ahead of Bronson on 5,000 units (15.8%).
With 7 brands splitting the Top 10 and 69.6% 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 $9.97 to $17.95, which frames the price band a competing listing has to justify.

Trending Mk 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: B097DD3G8G booked 1K units at $99.00, with ▲ 100.0% MoM change. On the growth side, B0BKH9LFJH leads positive momentum with ▲ 25.0% MoM growth on 500 units, with B01H3W4B8E close behind at ▲ 20.0% MoM on 600 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
