Women Multivitamin Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

THORNE is the best-performing women multivitamin brand in July 2026, moving 70,000 units across 2 ASINs for 21.9% of Top 10 volume. OLLY follows with 50,000 units (15.6%), ahead of Centrum on 40,000 units (12.5%).

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 $14.00 to $36.50, 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: B014G4AY1A booked 20K units at $12.88, with ▲ 0.0% MoM change. On the growth side, B099GWS9QW leads positive momentum with ▲ 50.0% MoM growth on 3K units, with B09KCCVL9V close behind at ▲ 33.3% MoM on 40K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
