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

Optimum Nutrition is the best-performing preworkout brand in July 2026, moving 20,000 units across 3 ASINs for 30.8% of Top 10 volume. RAW follows with 14,000 units (21.5%), ahead of C4 on 13,000 units (20.0%).

With 6 brands splitting the Top 10 and 72.3% 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 $20.95 to $26.12, 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: B0CBCRXM65 booked 7K units at $22.99, with ▲ 16.7% MoM change. On the growth side, B07WK4H9KM leads positive momentum with ▲ 100.0% MoM growth on 2K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
