Best Thorne Vitamin D Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)

Trending Thorne Vitamin D 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: B0018CJ17W booked 20K units at $41.00, with ▲ 100.0% MoM change. On the growth side, B0F9F5JWXW leads positive momentum with ▲ 100.0% MoM growth on 20K units, with B0FQLGSTBB close behind at ▲ 33.3% MoM on 4K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
