Citrulline Malate Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Nutricost is the best-performing citrulline malate brand in July 2026, moving 20,000 units across 3 ASINs for 34.5% of Top 10 volume. Six Star follows with 9,000 units (15.5%), ahead of C4 on 8,000 units (13.8%).

With 7 brands splitting the Top 10 and 63.8% 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 $15.73 to $22.62, 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: B0CM9RJ7BW booked 4K units at $17.97, with ▲ 33.3% MoM change. On the growth side, B00NBCVVWA leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B0DWD26MMF close behind at ▲ 60.0% MoM on 800 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
