Welcome to Lasting Fullness & Better Appetite Control

…and say goodbye to constant cravings, sluggish digestion, and irregularity

Most adults don't get the 25–38 grams of daily fiber experts recommend, making it harder to support fullness, regularity, and a healthy gut. Momentous Fiber+ helps close that gap with a 3-in-1 fiber blend of psyllium husk, rice bran, and Solnul® resistant potato starch. Psyllium helps promote fullness and satiety, while rice bran supports stool bulk and regularity. Solnul® resistant potato starch feeds beneficial gut bacteria and supports the natural pathways involved in GLP-1 signalling. Together, they provide comprehensive daily support for appetite control, comfortable digestion, regularity, and gut health.

The Formula That Brings Results

Soluble + Insoluble Fiber Blend

Psyllium husk (soluble) and rice bran (insoluble) hydrate and bulk stool, promoting smooth, regular digestion without harsh stimulants. Psyllium also absorbs water and forms a gel, helping promote fullness and satiety.

Prebiotic Microbiome Matrix

Solnul® resistant potato starch ferments in the colon into SCFAs like butyrate, strengthening the gut barrier and feeding beneficial bacteria like Bifidobacterium and Akkermansia. This supports the natural gut pathways involved in satiety and metabolic signaling.

Metabolic & Energy Stability Complex

Soluble fiber slows carb absorption to moderate blood sugar, while SCFAs boost insulin sensitivity—supporting steady energy without spikes and crashes. By slowing digestion and helping moderate blood sugar, soluble fiber can also support lasting satisfaction after meals.

Gut–Brain Axis Support

SCFAs support gut-brain signaling tied to inflammation and neurotransmitter activity—helping reinforce focus, mood, and mental clarity.

Feel Fuller Longer

Psyllium absorbs water and forms a gel that adds volume in the digestive tract, helping promote fullness and satisfaction between meals.

Support Appetite & Satiety

The combination of viscous psyllium and prebiotic resistant starch provides support for satiety and natural gut signaling. They help you get more from your daily fiber intake while supporting the pathways involved in appetite regulation.

 

Stay Regular & Comfortable

Psyllium helps hydrate stool while insoluble rice bran adds bulk, supporting smooth, regular bowel movements and comfortable digestion without harsh stimulants.

Nourish Your Gut Microbiome

Solnul® resistant potato starch acts as a prebiotic, feeding beneficial gut bacteria and producing SCFAs like butyrate to support a healthy, resilient microbiome.

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 – supporting fullness, appetite control, smoother digestion, regularity, and a healthier gut microbiome over time.

How to use

Follow these 3 simple steps to get the most out of your fiber supplement:

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.

What Our Customers Are Saying

Priya R.

Fuller All Day

I started adding Fiber+ to my morning routine and noticed I wasn't thinking about snacks as much between meals. I feel more satisfied after eating and don't get that constant hungry feeling in the afternoon.

Maya T.

Regular Again, Zero Bloat

My digestion feels much more consistent since I started using this. I'm regular without feeling overly bloated or uncomfortable, and it's been easy to make it part of my daily routine.

Elena V.

Less Hunger Between Meals

I wanted something to help me get more fiber and stay satisfied longer. Fiber+ has made it easier to go from one meal to the next without constantly feeling like I need a snack.

Brandon K.

The Cinnamon Is Unreal

I genuinely look forward to this. The cinnamon tastes like a warm bowl of cereal, and it stirs into water without a single clump.

Hannah W.

Gentle and Easy Every Day

I've tried other fiber supplements that felt like too much for my stomach. This one feels much gentler, and I can take it consistently without the same uncomfortable feeling.

Daniel B.

Quality I Don't Question

The NSF Certified for Sport and third-party testing gave me confidence in the quality. I also like that I'm getting multiple types of fiber in one simple daily scoop.

Frequently Asked Questions

Yes. Fiber+ contains soluble psyllium husk, which absorbs water and forms a gel in the digestive tract. This can increase volume and help promote feelings of fullness and satisfaction between meals. Combined with the prebiotic benefits of resistant starch, Fiber+ provides daily support for satiety and appetite management.

Fiber+ is a useful addition to a routine focused on appetite management. Its psyllium content helps promote fullness, while Solnul® resistant potato starch provides prebiotic fiber that supports beneficial gut bacteria and natural gut signaling. Together, these fibers can help you feel more satisfied between meals while increasing your daily fiber intake.
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.
Fiber can be particularly useful for people taking GLP-1 medications because reduced appetite and smaller meals can make it harder to get enough fiber from food alone. Fiber+ provides 6 g of fiber per serving from soluble, insoluble, and resistant starch sources, supporting regularity, fullness, and gut health.
