No, fiber doesn’t work like creatine. It’s not going to give you a pump or add 5 lbs to your squat overnight. But when it comes to long-term health, fiber is one of the most overlooked, under-consumed, and impactful nutrients in the modern diet.
Most People Don’t Get Enough Fiber
The average adult should be consuming 25–38 grams of fiber per day, yet most people barely crack half of that. And for a long time, we thought fiber’s only job was to keep things moving in the bathroom.
Turns out… that was just scratching the surface.
Fiber & the Gut Microbiome
Over the last few years, research has really shifted toward understanding the gut microbiome—the trillions of bacteria living in your digestive tract—and how deeply it affects overall health.
Adequate fiber intake helps support:
- Digestive health & regularity
- Immune system function
- Brain health & cognitive function
- Blood sugar regulation
- Cholesterol management
- Bone health
- Inflammation control
Why? Because fiber feeds your gut bacteria. Healthy bacteria produce compounds like short-chain fatty acids that communicate with your immune system, your brain, and even your metabolism.
A Simple Way to Boost Intake
While whole foods should always be the foundation, supplements can be a practical tool—especially for people who struggle to consistently hit fiber targets.
One option we carry is Fiber Fuel by Apollon Nutrition, which provides 7 grams of fiber per serving from multiple complementary sources.
Using a blend like this helps support the microbiome from multiple angles rather than relying on a single fiber type.

The Big Takeaway
Fiber isn’t flashy—but it’s foundational.
If you want to support:
- Digestive health
- Immune health
- Brain function
- Long-term metabolic health
…fiber needs to be part of the conversation.
That doesn’t mean it has to come from a supplement, but it does mean being intentional about your intake. Food first when possible, supplements when helpful.
We carry several fiber options here at The Nutrition Store, and we’re always happy to help you find the right fit based on your goals, diet, and tolerance.
If 2026 is about building real health, not just chasing trends, fiber deserves a seat at the table.
