Creatine Monohydrate Powder Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Nutricost is the best-performing creatine monohydrate powder brand in July 2026, moving 130,000 units across 2 ASINs for 27.1% of Top 10 volume. THORNE follows with 130,000 units (27.1%), ahead of Optimum Nutrition on 110,000 units (22.9%).

With 6 brands splitting the Top 10 and 77.1% 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 $16.34 to $40.00, 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: B00E9M4XFI booked 20K units at $20.97, with ▲ 0.0% MoM change. On the growth side, B0F69BJ2NW leads positive momentum with ▲ 150.0% MoM growth on 5K units, with B0DJWVMRR9 close behind at ▲ 100.0% MoM on 4K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
