Folate Supplement Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

THORNE is the best-performing folate supplement brand in July 2026, moving 60,000 units across 3 ASINs for 39.2% of Top 10 volume. Triquetra Health follows with 58,000 units (37.9%), ahead of Nature Made on 10,000 units (6.5%).

With 6 brands splitting the Top 10 and 83.7% 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 $5.59 to $29.00, 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: B01IJR5VM2 booked 7K units at $13.99, with ▼ 12.5% MoM change. On the growth side, B0GQXDQHQH leads positive momentum with ▲ 100.0% MoM growth on 1K units, with B0DCZTJSL9 close behind at ▲ 50.0% MoM on 3K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
