Protein & Fibre Demand Driving Complex Formulations; GLP-1 Impact Noted
Rising consumer demand for protein and fibre, reinforced by GLP-1 awareness, is challenging formulators to balance nutrient density with sensory appeal. Ardent Mills reports 80% of its 2026 R&D projects focus on these ingredients.

Consumer interest in high-protein and high-fibre nutrition is creating significant formulation challenges for manufacturers across the food and supplement sectors. Ardent Mills, a major North American flour and ingredient supplier, indicates that 80% of its current R&D pipeline is dedicated to projects incorporating these attributes. This surge is driven by evolving consumer preferences for satiety, digestive health, and weight management, further amplified by the public discourse around GLP-1 medications, as noted by Anke Golde, Senior Director for R&D at Ardent Mills, speaking to Food Ingredients First.
Integrating higher levels of protein and fibre into familiar product formats poses considerable technical hurdles. Simply increasing ingredient volumes often compromises taste, texture, and overall eating experience. For example, excess fibre can lead to dense, dry, or gritty textures, while protein additions can alter viscosity and structural integrity, particularly in grain-based applications. Formulators must meticulously balance different fibre types, optimise hydration, and combine them with specific proteins or texturising agents like hydrocolloids or emulsifiers to maintain sensory quality and digestive tolerance.
The functional disruption is particularly acute in traditional baked goods. Wheat-based systems rely on starch gelatinisation and gluten development for structure; high protein or fibre loads can interfere with these mechanisms, affecting dough handling, processing performance, and finished product quality. Manufacturers must consider the intricate interactions between ingredients, not just their individual nutritional contributions. This necessitates a deep understanding of ingredient functionality to deliver desired benefits without detrimentally impacting product consistency or consumer appeal.
A key strategy emerging is 'benefit stacking,' where ingredients contribute multiple nutritional advantages within a single formulation. Chickpea flour, for instance, offers both protein and fibre, but its inclusion demands careful consideration of its interaction profile. The imperative is to deliver nutrient-dense, satisfying products that retain the sensory attributes essential for repeat purchases, moving beyond individual ingredient additions to holistic formulation systems.
What this means for North America
Supplement manufacturers in North America must prioritise significant investment in R&D to reformulate existing products and develop new SKUs that meet the heightened demand for protein and fibre. This implies increased budgets for ingredient sourcing, with a focus on advanced functional ingredients that enable 'benefit stacking' and mitigate sensory challenges, potentially increasing COGS by 10-15%. Brand owners should expect longer reformulation windows, requiring close collaboration with contract manufacturers to manage complex ingredient interactions and processing adjustments. Early engagement with ingredient suppliers is critical to secure supply and manage pricing volatility for specialised high-protein flours and functional fibres, especially given Ardent Mills' reported 80% R&D focus on these areas.
This trend is being actively addressed by UK manufacturing partners including Supplement Factory.
