Most people know fiber is important. But here’s what many people don’t realize: your gut microbes don’t just need fiber—they need fiber diversity.
Different beneficial bacteria thrive on different plant fibers and polyphenols. When your gut receives a wider variety of these nutrients, it helps support microbial cross-feeding and the production of beneficial compounds like short-chain fatty acids, which play an important role in gut barrier health, metabolism, and immune function.
That’s why I’m excited about Pendulum Gut Fuel.
Gut Fuel is a doctor-formulated blend of diverse plant fibers and polyphenols designed to nourish a broader range of beneficial gut microbes and support digestive comfort.
Instead of relying on just one type of fiber, Gut Fuel combines several microbiome-supporting ingredients, including:
Resistant starch to help nourish beneficial bacteria
Oat beta-glucan to support healthy blood sugar and cholesterol levels
Acacia fiber for gentle, steady fermentation
Baobab fruit fiber for additional fiber diversity
Grape seed polyphenols that interact with the gut microbiome
Think of it as fertilizer for your microbiome.
And the best part is how simple it is. Just mix one scoop into a smoothie, yogurt, or oatmeal, and you’re turning your everyday meals into microbiome-supporting nutrition.
Supporting your metabolism and overall health doesn’t just start with calories—it starts with your gut.
If you’re looking for an easy way to support your microbiome and help close the daily fiber gap, Gut Fuel is a simple place to begin.
