Clinical Substantiation Becomes a Retail Listing Requirement
Major pharmacy and grocery chains have begun requiring published clinical or pharmacokinetic data before granting or renewing planogram space for children's supplement brands, a shift that started with immunity gummies in 2023 and has since spread to cognitive and gut-health formulas. Brands lacking a dedicated research budget now face delisting risk even with strong sell-through, since buyers increasingly weight evidence quality alongside velocity when deciding annual category resets. Contract manufacturers report a 34 percent rise in requests for stability and bioavailability testing packages since 2023, reflecting how deeply this requirement has reshaped supplier relationships across the value chain.
