Dr Althea Vitamin C Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

celimax is the best-performing dr althea vitamin c brand in July 2026, moving 100,000 units across 1 ASIN for 32.3% of Top 10 volume. Dr.Althea follows with 50,000 units (16.1%), ahead of EQQUALBERRY on 40,000 units (12.9%).

With 9 brands splitting the Top 10 and 61.3% 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 $18.50 to $27.00, 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: B074NNVLCM booked 10K units at $14.80, with ▲ 0.0% MoM change. On the growth side, B07PK2P2XB leads positive momentum with ▲ 566.7% MoM growth on 4K units, with B0GSVHQT27 close behind at ▲ 14.3% MoM on 800 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
