Black Walnut Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Clean Nutraceuticals is the best-performing black walnut brand in July 2026, moving 16,000 units across 2 ASINs for 24.6% of Top 10 volume. 365 by Whole Foods Market follows with 10,000 units (15.4%), ahead of VINATURA on 10,000 units (15.4%).

Volume is spread across 9 brands, with the top three holding 55.4% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $7.49 to $24.95, 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: B0GTSX993D booked 4K units at $21.99, with ▲ 300.0% MoM change. On the growth side, B0H1W55SRB leads positive momentum with ▲ 900.0% MoM growth on 1K units, with B0H25NG51W close behind at ▲ 566.7% 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
