Krill Oil Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

MegaRed is the best-performing krill oil brand in July 2026, moving 28,000 units across 4 ASINs for 50.0% of Top 10 volume. Carlyle follows with 8,000 units (14.3%), ahead of Bronson on 8,000 units (14.3%).

With 6 brands splitting the Top 10 and 78.6% 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 $19.78 to $28.80, 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: B00JPD5ZJ4 booked 3K units at $31.99, with ▲ 0.0% MoM change. On the growth side, B0GVYYGVLC leads positive momentum with ▲ 150.0% MoM growth on 1K units, with B0F4HPY7D5 close behind at ▲ 66.7% 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
