D3 K2 Vitamin 5000 Iu Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Sports Research is the best-performing d3 k2 vitamin 5000 iu brand in July 2026, moving 90,000 units across 1 ASIN for 26.5% of Top 10 volume. Nature Made follows with 70,000 units (20.6%), ahead of Dr. Berg Nutritionals on 50,000 units (14.7%).

With 8 brands splitting the Top 10 and 61.8% 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 $12.80 to $26.99, 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, 2 ASINs forced its way in: B00DN4VCA2 booked 20K units at $14.40, with ▲ 0.0% MoM change. On the growth side, B0H2M1NC5X leads positive momentum with ▲ 400.0% MoM growth on 3K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
