Best Cod Liver Oil Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
Sports Research is the best-performing cod liver oil brand in July 2026, moving 60,000 units across 1 ASIN for 57.1% of Top 10 volume. THORNE follows with 20,000 units (19.0%), ahead of Dr. Berg Nutritionals on 10,000 units (9.5%).
With 7 brands splitting the Top 10 and 85.7% 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 $27.95 to $41.00, which frames the price band a competing listing has to justify.

Trending Cod Liver Oil Products — Growth Leaders & New Top 10 Entrants
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, B0C6N2N1WW leads positive momentum with ▲ 150.0% MoM growth on 500 units, with B0018CJ17W close behind at ▲ 100.0% MoM on 20K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
