Electrolyte Powder Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Liquid I.V. is the best-performing electrolyte powder brand in July 2026, moving 130,000 units across 4 ASINs for 36.1% of Top 10 volume. Ultima Replenisher follows with 80,000 units (22.2%), ahead of Drink LMNT on 50,000 units (13.9%).

With 6 brands splitting the Top 10 and 72.2% 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 $24.02 to $45.00, 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: B0DN6T1QGD booked 20K units at $9.99, with ▲ 100.0% MoM change. On the growth side, B0GSZZJFXM leads positive momentum with ▲ 125.0% MoM growth on 9K units, with B0D4R4YF8J close behind at ▲ 60.0% 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
