Multivitamins Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Centrum is the best-performing multivitamins brand in July 2026, moving 70,000 units across 2 ASINs for 20.6% of Top 10 volume. ONE A DAY follows with 60,000 units (17.6%), ahead of THORNE on 40,000 units (11.8%).

Volume is spread across 8 brands, with the top three holding 50.0% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $15.73 to $36.00, 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, one ASIN forced its way in: B09QBKGDLS booked 20K units at $17.47, with ▼ 33.3% MoM change. On the growth side, B09KCCVL9V leads positive momentum with ▲ 33.3% MoM growth on 40K units, with B0877WJHN7 close behind at ▲ 12.5% MoM on 9K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
