Peru's Mandatory FOP Labels Drive Significant Product Reformulation
New research from Peru demonstrates that mandatory front-of-pack (FOP) warning labels compel manufacturers to reformulate products, reducing sugar, sodium, and saturated fat content. This policy-driven change impacts product formulation strategies and market access for non-compliant goods.

Lima, Peru — 13 August 2026
Mandatory front-of-pack (FOP) warning labels in Peru have successfully driven significant reformulation across the packaged food and beverage industry, according to a recent pre- and post-operational study by the University of North Carolina at Chapel Hill’s Global Food Research Program (GFRP). Introduced in June 2019, the policy mandates black warning labels on products exceeding defined thresholds for total sugars, sodium, saturated fats, or containing trans fats. This regulation aimed not only to inform consumers but also to force manufacturers into product improvement, directly influencing ingredient procurement and formulation strategies.
The GFRP study, which analysed 3,805 products in Peruvian supermarkets, found a notable decline in the proportion of items requiring warning labels after the policy's first phase. The percentage of foods carrying at least one label fell from 61% to 55%, while beverages saw a more substantial drop from 31% to 19%. This shift was attributed to product reformulation rather than market exit, confirming that the policy incentivised changes to existing product profiles. Companies adjusted formulations to avoid the negative commercial impact of prominent warning labels, directly affecting their ingredient sourcing and R&D budgets.
Specific nutrient reductions were significant. Among products originally high in sugar, the proportion decreased by 10% for foods and 37% for beverages. Sodium levels in foods high in the nutrient decreased by 16%, and saturated fats in foods dropped by 7%. These reformulations were further encouraged by complementary policies, including a 2016 mandate to eliminate trans fats and a 2018 increase in taxes on high-sugar beverages from 17% to 25%. Additionally, products bearing FOP warning labels are banned from sale in school cafeterias and from all advertising platforms, including television and social media, imposing significant marketing restrictions on non-compliant products.
What this means for Peru
Peruvian supplement manufacturers and brand owners must actively monitor and adapt to evolving FOP labelling regulations, even if directly aimed at conventional foods, as these signals often precede similar measures for dietary supplements. Non-compliance could result in substantial market access restrictions, including bans from school channels and advertising limitations. Investment in R&D for low-sugar, low-sodium, and lower-fat formulations is now a competitive imperative. This regulatory environment creates a clear market advantage for brands proactively developing products that meet or exceed these health-oriented thresholds, influencing ingredient choice and costing models for new product development and existing portfolio reformulation.
The Peruvian experience demonstrates that robust public health policies can effectively drive industry-wide reformulation. These findings provide a blueprint for other nations considering similar regulatory approaches to combat non-communicable diseases. For supplement manufacturers operating or planning to enter markets with similar FOP labelling initiatives, understanding the specific thresholds and consumer response to these labels is critical for product development and marketing strategies.
