Supplement sales are growing steadily, with the global dietary supplements market forecast to rise at an 8.9% CAGR over 2024 to 2028, but customer behavior is moving faster than you might expect. At the same time, U.S. consumers are set to spend about $36.2 billion on supplements in 2024 while 30% already prefer buying online, and compliance expectations are rising with 51% wanting clinically studied ingredients. The mix of chronic condition usage and category cravings, along with the quality and enforcement pressure behind the scenes, makes for a surprisingly uneven picture that is worth unpacking.
