Best Plan B Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
Ohm is the best-performing plan b brand in July 2026, moving 11,000 units across 2 ASINs for 41.8% of Top 10 volume. Rephresh follows with 10,000 units (38.0%), ahead of Designs for Health on 2,000 units (7.6%).
With 9 brands splitting the Top 10 and 87.5% 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 $14.24 to $52.99, which frames the price band a competing listing has to justify.

Trending Plan B 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, B0CV6X5WFQ leads positive momentum with ▲ 25.0% MoM growth 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
