Key Highlights – Functional fiber trends & the GLP-1 era
- The microbiome is becoming a central driver of innovation in dietary supplements and functional Food & Beverage, shifting the focus from digestive comfort to targeted microbiota modulation and diversity.
- Prebiotics are gaining momentum, with growing interest in their ability to selectively nourish beneficial bacteria and support microbiome balance.
- New consumption patterns, including those driven by GLP-1, are creating opportunities for microbiome-focused solutions.
- Differentiation increasingly relies on the ability to demonstrate effects on specific bacterial populations and clinically proven benefits.
Each year on June 27, World Microbiome Day highlights the critical role of microbial ecosystems in human health. What was once a niche scientific topic is now reshaping innovation across dietary supplements and functional Food & Beverage.
Beyond general gut health, the focus is shifting toward microbiome modulation, diversity, and targeted bacterial stimulation, redefining how formulators approach ingredient selection and product positioning.
Consumers are becoming microbiome-conscious
Consumer awareness around gut health has accelerated dramatically over the past decade. What started as a focus on digestive comfort has evolved into a broader understanding of the microbiome as a central hub influencing immunity, energy, mood, and overall wellbeing.
A healthy gut is now widely recognized as a cornerstone of long-term health. Beyond digestion, the gut microbiome influences metabolism, immune function, and even brain activity. When diverse and balanced, it supports energy production, nutrient absorption, mood regulation, and resilience.

This growing awareness is reflected in consumer behavior. Gut health is now considered a top health priority globally, and a majority of consumers familiar with the microbiome report having already adapted their diet accordingly.
At the same time, interest in prebiotics continues to rise, as consumers better understand their role in supporting beneficial bacteria and microbiome balance. Younger generations, in particular, are driving this shift, with higher levels of awareness and engagement around microbiome-related topics.
5 R&D strategies to meet the growing demand for microbiome-focused products
1. Think beyond digestion: embrace a holistic microbiome approach
Gut health is no longer just about digestive comfort. Consumers increasingly associate the microbiome with multiple health dimensions, from immunity to cognitive function via the gut–brain axis.
For formulators, this means designing products that deliver broader value propositions. Ingredients that support microbiome balance can now be positioned within multi-benefit solutions, connecting gut health to energy, mood, or metabolic wellbeing, all without adding complexity to the consumer experience.
2. Support microbiome diversity through targeted prebiotic combinations
As microbiome science advances, diversity has emerged as a key marker of gut health. A richer and more diverse microbiota is associated with better resilience and overall wellbeing.
This is reflected in dietary approaches such as the “30 plant points per week” concept, which promotes the consumption of a wide variety of plant-based foods to support microbial diversity.
For formulators, this translates into the need to go beyond single-ingredient approaches. Combining complementary prebiotics can help stimulate a broader range of beneficial bacteria.
For example, solutions such as inavea™ Carob & Acacia, combining two distinct fiber sources, are designed to promote microbiome diversity, unlike some ingredients that may favor a more limited bacterial profile.
3. Address new consumption behaviors shaped by GLP‑1

The rise of GLP‑1 solutions is already reshaping eating behaviors at scale. Reduced appetite and changing expectations around satiety and digestive comfort are redefining what consumers expect from Food & Beverage products.
From a microbiome perspective, this raises new questions: how can we maintain gut balance and microbial activity despite reduced food intake?
The field of prebiotics is evolving toward more targeted approaches. Next-generation bacteria such as Akkermansia muciniphila are attracting growing attention due to their association with metabolic health and weight management.
Nexira’s research has shown that VinOgrape™ Plus can promote the growth of this specific bacterium, highlighting the potential of prebiotics to support metabolic health through microbiome modulation.
4. Make science visible and credible
As interest in the microbiome grows, so does the demand for proof. Consumers are no longer satisfied with generic health claims, they expect transparency, clinical evidence, and reassurance.
For brands, this translates into a need to rely on scientifically validated ingredients and to communicate their benefits clearly. Translating complex science into simple, actionable benefits is becoming a key differentiation factor.
Beyond general claims, differentiation increasingly comes from the ability to demonstrate effects on specific bacterial populations, rather than only broad microbiome support.
This approach is illustrated by Nexira’s long-standing work on acacia-based prebiotics. Acacia fiber is one of the most extensively studied prebiotic fibers available, with clinically demonstrated effects at 10 g/day, including the stimulation of beneficial bacteria such as Lactobacilli and Bifidobacteria, key markers of a balanced gut microbiota.
This body of evidence builds on decades of research and is reflected in flagship ingredients such as Fibregum™, which celebrates 30 years of expertise in 2026, illustrating Nexira’s long-term commitment to advancing microbiome science.
