Should dietary supplements be required to follow the same standardized date-labeling rules as conventional food products?
California enacted AB 2779, which excludes dietary supplements from the standardized date-labeling system established in 2024. This change removes the requirement for manufacturers to use specific terminology like 'Best if Used By' on supplement packaging.
Why it matters
The exemption clarifies that standardized labeling rules were designed for conventional food safety, which differs from the potency and shelf-life metrics used for supplements. This move aims to prevent labeling disruptions and compliance uncertainty for the industry.
The legislative record confirms that AB 2779 updates the scope of AB 660, which set the state's standardized labeling system. The shift marks a definitive policy change for all supplement manufacturers operating within California, though the real-world effect on product labels remains to be seen.
The players
Council for Responsible Nutrition
A trade association representing the dietary supplement and functional food industry that advocated for regulatory clarity.
The details
The law operates by narrowing the legal definition of 'food items' that are subject to the standardized date-labeling rules passed in 2024. By excluding dietary supplements, the state prevents manufacturers from needing to adopt specific 'Best if Used By' or 'Use By' language that was originally intended to reduce food waste and clarify safety for perishable goods. The Council for Responsible Nutrition supported this adjustment to ensure clarity in compliance for supplement producers.
Timeline
California established its standardized food date-labeling system in 2024 under AB 660.
The supplement exemption under AB 2779 was enacted in September 2026.
Health Landscape
This law represents a recalibration of state-level labeling oversight as it attempts to distinguish between conventional food products and dietary supplements. It clarifies the boundary between safety-focused food policy and the distinct regulatory requirements governing supplement potency and shelf life.
Consumers in California may notice a continuation of existing labeling practices on their supplement bottles rather than a shift toward the new standard date terminology. If you have questions regarding the shelf life or potency of a specific supplement, continue to consult the manufacturer's guidance or your physician.
The takeaway
California has opted to remove dietary supplements from its new food date-labeling requirements to avoid confusion between food-safety labels and supplement-potency dates. Check the manufacturer's specific guidance if you are concerned about the freshness of a long-stored supplement product.
