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

Ultima Replenisher is the best-performing nuun hydration tablets brand in July 2026, moving 80,000 units across 2 ASINs for 27.6% of Top 10 volume. Liquid I.V. follows with 80,000 units (27.6%), ahead of Drink LMNT on 50,000 units (17.2%).

With 7 brands splitting the Top 10 and 72.4% 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 $21.83 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: B018NZJBSA booked 10K units at $21.75, with ▲ 0.0% MoM change. On the growth side, B019GU4J56 leads positive momentum with ▲ 100.0% MoM growth on 10K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
