Three signals worth watching

  • GLP-1 companion supplements: 10× since 2023. Muscle-preservation stacks, electrolytes, and protein sold as GLP-1 support did not exist three years ago.

  • Amazon’s share of DTC supplements: approximately 40%. For most challenger brands, Amazon is now the single biggest sales channel.

BREAKOUT · CREATINE

“Creatine is the new protein. 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 single one of them is now a supplement customer: protein, electrolytes, muscle support, hair.”

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, and nothing hiding behind a proprietary blend.

The market is big, and growing fast. Get tested with a top-tier lab such as NSF or Eurofins, then show the actual certificate on your Amazon listing, website, and social channels. Shoppers are paying attention—and that’s a way to earn an edge.
