Collagen Stick Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Vital Proteins is the best-performing collagen stick brand in July 2026, moving 220,000 units across 4 ASINs for 45.8% of Top 10 volume. medicube follows with 140,000 units (29.2%), ahead of Dr.Melaxin on 70,000 units (14.6%).

With 6 brands splitting the Top 10 and 89.6% 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 $19.00 to $30.19, 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: B0GVQ6NYR3 booked 50K units at $29.90. On the growth side, B0CWJTRCWW leads positive momentum with ▲ 500.0% MoM growth on 600 units, with B0D3FQWRV4 close behind at ▲ 25.0% MoM on 5K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
