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

Nutricost is the best-performing momentous creatine brand in July 2026, moving 130,000 units across 2 ASINs for 29.5% of Top 10 volume. THORNE follows with 130,000 units (29.5%), ahead of Optimum Nutrition on 90,000 units (20.5%).

With 6 brands splitting the Top 10 and 79.5% 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 $29.32 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: B000GIQS0W booked 20K units at $49.99, with ▲ 100.0% MoM change. On the growth side, B0FW2GNKRZ leads positive momentum with ▲ 400.0% MoM growth on 5K units, with B0F8BFSCC7 close behind at ▲ 100.0% MoM on 8K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
