Best Ferritin Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
THORNE is the best-performing ferritin brand in July 2026, moving 70,000 units across 2 ASINs for 30.4% of Top 10 volume. Nature Made follows with 50,000 units (21.7%), ahead of MARYRUTH'S on 30,000 units (13.0%).
With 8 brands splitting the Top 10 and 65.2% 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 $7.06 to $38.95, which frames the price band a competing listing has to justify.

Trending Ferritin 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. Specifically, one ASIN forced its way in: B0061GLELG booked 10K units at $4.99, with ▲ 0.0% MoM change. On the growth side, B01N5MH5R5 leads positive momentum with ▲ 233.3% MoM growth on 1K units, with B0CBK2672G close behind at ▲ 100.0% MoM on 2K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
