Vitamin B2 Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Nature Made is the best-performing vitamin b2 brand in July 2026, moving 30,000 units across 1 ASIN for 20.1% of Top 10 volume. Nature's Bounty follows with 20,000 units (13.4%), ahead of Life Extension on 20,000 units (13.4%).

Volume is spread across 9 brands, with the top three holding 47.0% 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 $8.97 to $9.99, 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. On the growth side, B005DXM34A leads positive momentum with ▲ 1400.0% MoM growth on 3K units, with B071H24C2Y 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
