Amazing Marketing Co.The Supplement Boom.
A category once ruled by legacy vitamin brands is being rebuilt in real time by creators, challenger brands, and a shopper who reads every label. Here's how fast it's moving in 2026 — and what actually sells.
Supplements are the fastest-moving corner of CPG — and the most crowded. This report is a fast read for brands, sellers, and operators who want to know where the growth is, which segments are heating up, and what shoppers care about before they hit "Buy" in 2026.
Numbers are sourced from public 2024–2026 research (Nutrition Business Journal, Grand View Research, SPINS, Circana, Statista, and Amazon category reports). Projections are flagged where used.

Ten segments, one very hungry shopper.
Share of global dietary supplement revenue by segment, 2025. Vitamins are still the anchor, but sports nutrition and weight management are the two engines pulling category growth in 2026.
Protein and creatine are the growth story — creatine alone has grown 3× on Amazon since 2023.
Muscle-preservation stacks, electrolytes, and protein sold as 'GLP-1 support' are a net-new sub-category.
For most challenger brands, Amazon is now the biggest single sales channel — bigger than Shopify.
Ten sub-categories doing all the work.
YoY US retail + Amazon revenue growth, 2024 → 2025. Not size — velocity. This is where new brands are being born and where existing brands should be planning next year's SKUs.
Breakout · Creatine"Creatine is the new protein. It went from bodybuilder shelf to Sephora energy in 24 months — and gummies are the format doing it."
Breakout · GLP-1 companion"13% of US adults have taken a GLP-1. Every one of them is a supplement customer now — protein, electrolytes, muscle support, hair."
Trust is the new taste.
Share of US supplement shoppers who say the attribute is "important" or "very important" when choosing a brand. The top three are all trust signals — not flavor, not price.
Ingredient panel is the #1 PDP element, ahead of reviews and price.
Certificate of Analysis or NSF/Informed Sport marks lift PDP conversion vs. identical listing without.
Shoppers now expect per-ingredient milligram doses. Blends are read as hiding.
Amazon is the shelf.
US channel share of supplement revenue, 2025. Amazon has quietly become the single largest supplement retailer in America. For most challenger brands under $30M, it's more than half of DTC revenue.
TikTok teaches. Amazon closes.
How US supplement shoppers say they first learned about a brand they bought in the last 12 months. Multi-select — most people cite 2+ sources.
The map of demand.
Top markets by share of global supplement revenue, 2025, with year-over-year growth. India, Brazil, and Southeast Asia are growing 2–3× faster than the mature US market — with less shelf competition.

| Europe (48 countries) | 14% | +7% | Regulation-heavy; clean-label mature. |

The category is being rebuilt by whoever can prove what's in the bottle.
The old moat — shelf space at Whole Foods and GNC — is gone. The new moat is a product a shopper trusts on the first PDP scroll: clinically dosed, third-party tested, no proprietary hiding, and a founder who's actually online.
Amazon is where that trust gets tested. It's the biggest single supplement retailer in America, the discovery engine most TikTok videos end on, and the channel where a well-run PPC program is the difference between a $2M brand and a $20M brand.
If you sell supplements — or you're about to — the question isn't whether the market is big. It's whether your listings, ads, and reviews are set up to catch the shopper the category is minting every day.
