Welcome to Smoother Digestion, Steady Energy & a Healthier Gut

…and say goodbye to bloating, irregularity, and energy crashes

Did you know that most adults fall well short of the 25–38 grams of fiber experts recommend each day—leaving gaps that can show up as bloating, irregular digestion, and unsteady energy? Momentous Fiber+ is designed to help close that gap with a smart 3-in-1 prebiotic formula: soluble fiber (psyllium husk), insoluble fiber (rice bran), and Solnul® resistant potato starch. This complete blend supports end-to-end digestion and regularity, feeds a healthy gut microbiome, helps steady your blood sugar and energy, and even supports the gut–brain connection—helping you feel lighter, more comfortable, and more focused every single day.

The Formula That Brings Results

Soluble + Insoluble Fiber Blend

Psyllium husk (soluble fiber) and rice bran (insoluble fiber) work together to boost stool hydration and add bulk, supporting smooth transit and consistent digestive comfort—promoting regularity without harsh stimulants.

Prebiotic Microbiome Matrix

Solnul® resistant potato starch reaches the colon and ferments into short-chain fatty acids (SCFAs) like butyrate, which strengthen the gut barrier and feed beneficial bacteria such as Bifidobacterium and Akkermansia—building a more resilient microbiome and supporting nutrient absorption.

Metabolic & Energy Stability Complex

Soluble fiber helps slow carbohydrate absorption to moderate post-meal blood sugar, while SCFAs support insulin sensitivity and metabolic efficiency—favoring steady, stable energy without spikes and crashes.

Gut–Brain Axis Support

Those same SCFAs influence gut signaling pathways tied to inflammation and neurotransmitter activity, supporting communication between the gut and brain—helping reinforce focus, mood, and consistent mental clarity.

Promotes Smoother, Regular Digestion

The 3-in-1 blend of soluble psyllium and insoluble rice bran supports stool bulk and smooth transit, promoting comfortable, regular digestion with less bloating—gentle daily support without harsh stimulants.

Feeds a Healthy Gut Microbiome

Solnul® resistant potato starch feeds beneficial gut bacteria like Bifidobacterium and Akkermansia and produces beneficial SCFAs such as butyrate, which strengthen the gut barrier and support better nutrient absorption.

 

Supports Steady, Stable Energy

Soluble fiber helps slow carbohydrate absorption to moderate post-meal blood sugar, while SCFAs support insulin sensitivity and metabolic stability—favoring steady, lasting energy without spikes or crashes.

Strengthens the Gut–Brain Connection

Because the gut and brain are deeply linked, the SCFAs produced by Fiber+ influence pathways tied to focus, mood, and stress response—helping you feel sharper and more clear-headed, day after day.

Consistency is the KEY!

For best results, take Momentous Fiber+ daily for at least 3–6 months. This gives your gut time to fully benefit from the 3-in-1 prebiotic formula of soluble psyllium, insoluble rice bran, and Solnul® resistant potato starch—helping support smoother digestion, a more resilient microbiome, steadier energy, and lasting metabolic and gut–brain health over time.

How to use

Follow these 3 simple steps to get the most out of your meal replacement shake:

1. Mix 2 scoops (6g fiber) with 12–16 fl oz of your preferred liquid; drink shortly after mixing.

2. Take it once daily—post-workout or evening works best.

3. Stay consistent for at least 3–6 months for the full benefits.

Frequently Asked Questions

Fiber plays a foundational role in performance and longevity because it supports the systems that make everything else work. The prebiotic fibers found in our 3-in-1 Fiber+ formula feed beneficial gut bacteria, which produce short-chain fatty acids (SCFAs) that strengthen the gut barrier and improve nutrient absorption. Soluble fiber helps stabilize blood sugar and energy, supporting metabolic health and insulin sensitivity over time. Higher fiber intake is also consistently linked to lower risk of cardiovascular disease and all-cause mortality, yet most people don’t get enough daily. Supporting your fiber intake helps ensure your training, nutrition, and recovery efforts deliver their full return.

Yes. Fiber+ is designed to support consistent, comfortable digestion — even with a busy, high-performance lifestyle. It combines soluble fiber (psyllium) to increase stool hydration and ease motility with insoluble fiber (rice bran) to add bulk and support smooth transit. Together, they promote regular bowel movements without harsh stimulants. The addition of prebiotic resistant starch also supports microbiome balance, which can help reduce bloating and digestive discomfort over time. When used consistently and paired with adequate hydration, Fiber+ helps keep digestion steady so your schedule and your training stay uninterrupted.
Yes, all of our products are third-party tested. But that’s not enough for us. That's why we created The Momentous Standard®: a higher bar for science, sourcing, and verification, backed by independent proof you can trust. Every finished batch of Fiber+ is certified through NSF Certified for Sport®, a respected independent program that verifies label accuracy and screens for hundreds of banned substances. If a batch fails to meet these independent standards, it does not ship, because only third-party certification can truly back that promise. We also take transparency a step further by publishing third-party test results via Light Labs on individual product pages and making Certificates of Analysis (COAs) available for every batch. We earn trust the hard way, by proving quality at every step, on every batch, with no shortcuts.
Most people notice improvements in digestive regularity within 12–48 hours, especially if increasing overall fiber intake. Full microbiome and metabolic benefits — including steadier energy and improved gut resilience — typically build over 1–4 weeks of consistent daily use. As with any fiber supplement, hydration and consistency are key to getting the best results.
Yes. Fiber+ is designed for daily use as part of a consistent performance and longevity routine. Dietary fiber is an essential nutrient, and most adults fall well below recommended daily intake levels, experts recommend 25-38 grams of fiber per day depending on age and sex. Supplementing helps close that gap in a reliable way. Fiber+ contains soluble fiber, insoluble fiber, and prebiotic resistant starch — all well-studied forms of fiber — and is made to The Momentous Standard® with no unnecessary additives. For best tolerance, start with a smaller amount if you’re new to fiber and increase gradually while maintaining good hydration.
