Methylated B Complex Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Nature Made is the best-performing methylated b complex brand in July 2026, moving 30,000 units across 1 ASIN for 19.0% of Top 10 volume. Triquetra Health follows with 30,000 units (19.0%), ahead of THORNE on 30,000 units (19.0%).

Volume is spread across 8 brands, with the top three holding 57.0% 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 $9.89 to $26.50, 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. On the growth side, B0DS233X1F leads positive momentum with ▲ 50.0% MoM growth on 3K units, with B07MPZFTF7 close behind at ▲ 42.9% MoM on 1K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
