Hydration Packets Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Liquid I.V. is the best-performing hydration packets brand in July 2026, moving 150,000 units across 4 ASINs for 36.6% of Top 10 volume. Drink LMNT follows with 100,000 units (24.4%), ahead of Ultima Replenisher on 60,000 units (14.6%).

With 6 brands splitting the Top 10 and 75.6% 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 $20.99 to $35.95, 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: B094QB6PH6 booked 30K units at $32.24, with ▲ 0.0% MoM change. On the growth side, B0DN6T1QGD leads positive momentum with ▲ 100.0% MoM growth on 20K units, with B019GU4J56 close behind at ▲ 100.0% MoM on 10K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
