B6 Vitamins Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Nature Made is the best-performing b6 vitamins brand in July 2026, moving 40,000 units across 2 ASINs for 35.7% of Top 10 volume. NUSAVA follows with 20,000 units (17.9%), ahead of Integrative Therapeutics on 10,000 units (8.9%).

With 9 brands splitting the Top 10 and 62.5% 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 $10.19 to $24.95, 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: B0CVP43YJ4 booked 4K units at $14.95, with ▲ 0.0% MoM change. On the growth side, B09PDN2RKX leads positive momentum with ▲ 700.0% MoM growth on 400 units, with B001F0R962 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
