Conclusion
People care about verified testing. There’s opportunity there.
Shelf space at Whole Foods and GNC used to be the hard part. It isn't anymore.
Now the hard part is a product a shopper trusts on the first scroll. Clinically dosed. Third-party tested. Nothing hiding behind a "proprietary blend." 71% of shoppers want third-party testing. 61% distrust blends.
Amazon is where most sales happen. 39% of US supplement revenue, and the place many TikTok videos direct to.
The market is big. And growing fast. Recommendation: make sure to get tested with one of the 2 most top-tier testing labs, either NSF or Eurofins. Then, show the actual results certificate on your Amazon listing, website and socials. Shoppers are now aware that some brands got exposed as having inaccurate results (largely due to viral social media videos) – so this is now a must – AND, also a way to get an edge.
