Fibermaxxing: What It Means for Food Formulators in 2026
The protein era in food and beverage is well-documented. High-protein claims drove reformulation queues, purchase decisions, and category innovation for the better part of a decade. Fiber is now following the same trajectory, and the pace is picking up fast.
The term “fibermaxxing” has moved from TikTok wellness culture into mainstream consumer behavior, describing the intentional effort to maximize daily fiber intake. According to Clarkston Consulting’s 2026 Food Trends Report, 90% of women and 97% of men in the U.S. still aren’t meeting their daily fiber requirements, which means the gap between consumer awareness and actual intake is significant and growing. For food companies, that gap is an opportunity.
Fiber and Protein Are Converging
What makes this moment different from earlier fiber trends is the convergence with protein. With GLP-1 adoption rising and consumers eating smaller portions, the expectation that food delivers more per bite has intensified. Fiber and protein together address satiety, gut health, and nutrient density in a way neither does alone. Brands are responding by treating them as a single functional system rather than two separate label claims.
What RS4 Resistant Starch Brings to the Formula
Not all fiber sources are equal from a formulation standpoint, and not all deliver the same functional benefit. FiberGem® is an RS4-type resistant wheat starch with 90% fiber content. Unlike conventional fiber additions, it resists enzymatic digestion in the small intestine and reaches the colon intact, where it fuels production of short-chain fatty acids including acetate, propionate, and butyrate. These compounds support gut microbiota health, intestinal barrier integrity, and metabolic balance, giving formulators a fiber source with a functional story that goes well beyond the nutrition panel. For a deeper look at the science, read our TECH-Talk on FiberGem® and gut health.
Because FiberGem® is wheat-based, it integrates predictably into bakery, cereal, and snack applications without the hydration and texture tradeoffs that come with many fiber additions.
A Complete System
Paired with GemPro® proteins, FiberGem® gives development teams a fiber and protein system built for the same applications, tested in the same formats, and designed to work together inside the formula. That’s the system the current consumer moment is asking for.
To see it in action, take a look at our Low-Carb Cinnamon Roll formula, one of the harder reformulation targets in sweet goods, built with FiberGem® carrying up to 30% of the formula alongside GemPro® HPG and GemPro® Prime-E.
