Best Weight Loss Supplement Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
Premier Protein is the best-performing weight loss supplement brand in July 2026, moving 160,000 units across 3 ASINs for 23.5% of Top 10 volume. Physician's CHOICE follows with 130,000 units (19.1%), ahead of Nutricost on 100,000 units (14.7%).
Volume is spread across 7 brands, with the top three holding 57.4% between them.

Average selling prices among the leaders run from $19.35 to $27.04, which frames the price band a competing listing has to justify.

Trending Weight Loss Supplement 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. Specifically, one ASIN forced its way in: B001TH7K0G booked 40K units at $25.13, with ▲ 100.0% MoM change. On the growth side, B06ZZ3PJQD leads positive momentum with ▲ 200.0% MoM growth on 30K units, with B01E3COD8K close behind at ▲ 50.0% MoM on 6K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
