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

Vital Proteins is the best-performing marine collagen brand in July 2026, moving 219,000 units across 4 ASINs for 70.9% of Top 10 volume. Sports Research follows with 33,000 units (10.7%), ahead of Vital Vitamins on 30,000 units (9.7%).

With 6 brands splitting the Top 10 and 91.3% 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 $23.95 to $33.95, 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, B091V2W4Z2 leads positive momentum with ▲ 900.0% MoM growth on 3K units, with B0CSJ88YKJ close behind at ▲ 150.0% 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
