When it comes to newsworthy nutrients, one might say that a bulk of attention has been put on fiber. The term “fibermaxxing” may be a newer term in the common vernacular, but the idea of adding more dietary fiber is poised to be a long-term lifestyle habit, comparable to and complementary with the simultaneous push for protein.

What is Fibermaxxing?

Fueled by social media coverage, fibermaxxing is about boosting one’s daily intake of fiber to improve gut health and overall wellness. Circana’s insights on consumer sentiments and behaviors confirm that fiber has moved from a nutrient of avoidance to a nutrient of intention that can enhance digestive health, weight management, blood sugar control, and even mental clarity.

Several converging factors are driving this mindset and practice. Awareness of gut health’s importance has been building in recent years, leading to a greater understanding of the role of fiber in supporting a diverse microbiome. A simultaneous emphasis on holistic health has underscored the value of foods and beverages that deliver on multiple benefits such as functionality, satiety, and natural or clean profiles. Adding to this is the rising use of GLP-1 medications for weight loss and other perceived health benefits, which places fibermaxxing at the forefront of shifting dietary and lifestyle choices.

Finding Fiber

Many consumers are receiving, sharing, and acting on messages about the importance of dietary fiber are accordingly seeking out fiber-forward products.

At Circana, we see fiber intake increasing through three pathways:

1. Inherent fiber from whole foods: Many people, especially health-motivated and younger consumers, are striving to eat more fresh fruits, vegetables, legumes, and grains that are already rich in fiber.

   
   

2. Fiber-added packaged foods and beverages: A wide variety of today’s packaged products, including bars, cereals, tortillas, snacks, yogurts, and drinks, feature fiber claims such as “high fiber” or “a good source of fiber.” These items may be naturally rich in fiber or fortified with extra fiber.

   
   

3. Supplements and functional formats: Circana’s data shows strong growth and momentum in fiber-forward powders, gummies, prebiotic blends, and digestive wellness products.

These pathways often overlap, as many consumers stack fiber across multiple occasions and formats. Our insights show that younger consumers, in particular, look for fiber from whole foods and supplements.

When Maxxing Is Too Much

Although the dietary benefits of fiber are clear, too much of a good thing is possible. Overconsumption – whether purposeful or unintentional – can lead to downsides such as digestive discomfort and reduced nutrient absorption, especially if fiber replaces or crowds out other foods. Additionally, when certain fiber types don’t match individual tolerances, negative gut reactions often occur.

Brands and retailers should keep this in mind when developing and promoting their products. As with other nutrition topics, education is crucial in helping people understand the balance between helpful and excessive consumption.

One of the biggest education gaps is the consideration of fiber as a single ingredient. The truth is more complex.

For example, certain fibers behave differently in the gut. Some fiber forms are better for gradual daily intake, while others are more concentrated and ideal for certain situations. In addition, tolerance varies widely by individual, life stage, and health status.

To help customers better understand the types and functions of fibers, brands can use their packaging and supporting marketing and merchandising resources to explain their products’ attributes and benefits. By not communicating clearly, brands risk negative experiences and longer-term reputation damage from dissatisfied consumers who experience unwanted effects from overconsumption.

How Brands and Retailers Can Lead Responsibly

Manufacturers that offer fiber-forward products and support those items with effective messaging can elevate their brand in an increasingly competitive fiber-focused marketplace. This is where fibermaxxing becomes a credibility opportunity, not just a claims race.

Brands can create messaging that resonates with consumers in a variety of ways. Based on our decades-long industry experience and insights on consumer sentiments and product launches that stick, we offer some suggestions:

• Shift the narrative from “more” to “right for you.” Position fiber as part of a balanced routine, not a daily competition.

• Educate without lecturing. Simple cues like “start slow,” “great for everyday use,” or “best enjoyed occasionally” help set expectations without overwhelming shoppers.

• Merchandise fiber by need state, not just nutrient. Instead of touting grams, emphasize more intuitive benefits related to your product, such as digestive comfort, fullness, weight management, and/or heart health.

• Embrace transparency and cultural trust. Consumers increasingly expect honesty around tolerance, especially in functional foods and beverages.

Fibermaxxing 2.0

Consumer interest in fibermaxxing is more than a fleeting fad. It reflects the overall approach to holistic, preventative health and signals that consumers are increasingly sophisticated in their approach to diet and wellness.

What’s ahead for the fibermaxxing movement? The current clamor for nutrients like fiber and protein is accompanied by advances in AI and other technologies that will create more personalized eating solutions. At the same time, savvier shoppers, along with health professionals, will hold brands more accountable for their product claims, underscoring the importance of transparency and clarity in messaging. The steady march towards harmonized well-being also provides opportunities for brands that offer foods and beverages that align with the desire for healthy living across ages and stages.

Ultimately, the next phase of fiber growth won’t be driven by which brands add the most, but by which ones help consumers feel the best.
