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

Physician's CHOICE is the best-performing emma digestive supplement brand in July 2026, moving 160,000 units across 4 ASINs for 48.5% of Top 10 volume. Amazon Basics follows with 60,000 units (18.2%), ahead of Seed on 40,000 units (12.1%).

With 7 brands splitting the Top 10 and 78.8% 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 $10.39 to $59.99, 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: B0FSWWF65H booked 10K units at $15.99. On the growth side, B0GZHYBSMV leads positive momentum with ▲ 1011.1% MoM growth on 10K units, with B09DDFCDTN close behind at ▲ 250.0% MoM on 7K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
