USDA Protein Content Labeling Scrutiny Intensifies
USDA and FDA guidance on substantiating protein content claims has tightened since 2024, requiring PDCAAS-adjusted protein values rather than raw gram counts on front-of-pack callouts for products marketed against a health claim. Brands using cheaper, lower-quality protein blends face relabeling costs and potential claim withdrawal, while isolate-grade formulations that already meet the stricter digestibility-corrected standard gain a defensible marketing edge. The rule change has pushed several regional co-packers to requalify recipes mid-cycle, adding formulation cost but also raising the bar against low-cost private label entrants that cannot absorb re-testing expenses as easily as scaled branded manufacturers can today.
