Rho Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Rho Nutrition is the best-performing rho brand in July 2026, moving 34,000 units across 6 ASINs for 54.8% of Top 10 volume. BodyHealth follows with 14,000 units (22.6%), ahead of Create on 10,000 units (16.1%).

With 4 brands splitting the Top 10 and 93.5% 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 $41.84 to $49.98, 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: B0CV4P4131 booked 2K units at $42.00, with ▲ 0.0% MoM change. On the growth side, B0GP33XJPY leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B0DRPRJVWN close behind at ▲ 66.7% MoM on 1K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
