Best Metamucil Brands on Amazon US — Top 2 Brand Sales Concentration (July 2026)
Metamucil is the best-performing metamucil brand in July 2026, moving 246,000 units across 9 ASINs for 98.0% of Top 10 volume. KIRKLAND follows with 5,000 units (2.0%).
With 2 brands splitting the Top 10 and 100.0% 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 $16.89 to $26.61, which frames the price band a competing listing has to justify.

Trending Metamucil Products — Growth Leaders & New Top 10 Entrants
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. On the growth side, B01N9692HZ leads positive momentum with ▲ 500.0% MoM growth on 300 units, with B07KYYP497 close behind at ▲ 233.3% MoM on 1K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
