Tudca Supplement Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Double Wood Supplements is the best-performing tudca supplement brand in July 2026, moving 10,000 units across 1 ASIN for 20.4% of Top 10 volume. Clean Nutraceuticals follows with 10,000 units (20.4%), ahead of Nutricost on 9,000 units (18.4%).

Volume is spread across 9 brands, with the top three holding 59.2% 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 $21.19 to $25.42, 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: B0DSJH8QYC booked 2K units at $14.36, with ▲ 100.0% MoM change. On the growth side, B0CQD37L43 leads positive momentum with ▲ 150.0% MoM growth on 1K units, with B0DJR8YRMG close behind at ▲ 50.0% MoM on 3K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
