End-to-End Digestive Support
- Combines soluble (psyllium) and insoluble (rice bran) fiber
- Supports digestive movement and stool bulk for regularity
- Promotes smoother digestion
How Fiber+ Works*
Builds a More Resilient Microbiome
- Solnul® resistant potato starch reaches the colon and ferments into short-chain fatty acids (SCFAs) like butyrate, which support gut barrier integrity and beneficial bacteria such as Bifidobacterium and Akkermansia.
- Key Ingredient: Solnul® Resistant Potato Starch
Supports Metabolic Stability
- Soluble fiber slows carbohydrate absorption to help moderate post-meal blood sugar, while SCFAs support insulin sensitivity and metabolic efficiency.
- Key Ingredients: Psyllium Husk + Solnul® Resistant Potato Starch
Supports the Gut–Brain Axis
- Fermentation of resistant starch produces short-chain fatty acids (SCFAs), which help regulate immune signaling and gut–brain communication pathways.
- Key Ingredients: Solnul® Resistant Potato Starch + Psyllium Husk
Promotes Stool Hydration & Motility
- Psyllium increases stool hydration and rice bran adds bulk, supporting smooth transit and consistent digestive comfort.
- Key Ingredients: Psyllium Husk + Rice Bran
Take 1 packet daily (6g of fiber).
New to fiber? Start with ½ packet (3g of fiber) daily for the first 1–2 weeks, then gradually work up to a full packet as your body adjusts.
Mix it your way. Stir into a small glass of cold or room-temperature water for best solubility. Use less liquid for a more concentrated drink.
You can also blend Fiber+ into a smoothie, stir it into yogurt, or sprinkle it over food. The best way to take it is the way you’ll take it every day.
Drink right away. Fiber thickens naturally as it absorbs liquid, which makes for a less enjoyable drinking experience.
Take at least 2 hours before or after medications.Should not be taken within two hours before or after taking iron.
*Experts recommend a daily fiber intake of 25-38 grams depending on age and body composition
6g dietary fiber in each travel-pack of Fiber+.

*Reb M is a natural, plant-based sweetener with zero glycemic response or aftertaste. Our Reb M is made from fermented rice and is 250× sweeter than sugar without bloating, 2.5× sweeter than monk fruit, and made sustainably with less land, water, and crop rotation.
Take Fiber+ at the time of day you can be most consistent — that’s what drives the biggest digestive and metabolic benefits. Morning hydration, with your first meal, in a protein shake, or evening wind-down all work.
You may notice easier, more regular stools within 12–48 hours, with fuller microbiome and metabolic benefits building over 1–4 weeks of steady use.
Expect improved bowel comfort, better stool quality, reduced bloating over time, and added satiety/steadier blood sugar when your intake is consistent.
There are 8 credible reviews and studies related to this product:
“Clinically shown to support beneficial gut bacteria at just 3.5g per day, including Bifidobacterium and Akkermansia.”
2. The impact of diet and lifestyle on gut microbiota and human health
“Prebiotics have been shown to improve bowel and immune function, metabolic health and mineral bioavailability in humans.”
3. The Health Benefits of Dietary Fibre
“The gut microflora functions as an important mediator of the beneficial effects of dietary fibre, including the regulation of appetite, metabolic processes and chronic inflammatory pathways.”
4. The Importance of Dietary Fiber for Metabolic Health
“Increased fiber intake was linked with lower total cholesterol, LDL cholesterol, triglycerides, body weight, and improved markers of metabolic health.”
"5 g/day increase in dietary fiber intake was associated with a 7% lower risk of all-cause mortality."
6. Beyond the gut: decoding the gut–immune–brain axis in health and disease
“SCFAs, which are produced primarily by microbial fermentation of dietary fiber, are essential regulators of innate and adaptive immunity.”
7. Role of brain-gut-muscle axis in human health and energy homeostasis
“SCFAs bind to receptors that help stimulate secretion of gut hormones like GLP-1 and PYY that communicate with the brain and influence appetite and energy balance.”
8. The gut-brain axis: interactions between enteric microbiota, central and enteric nervous systems
“One of the main products of bacterial metabolism are short-chain fatty acids (SCFAs)… that are able to stimulate … mucosal serotonin release and influence memory and learning processes.”

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.
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.
Yes — Fiber+ can be taken with most supplements and protein shakes as part of your daily routine.
Because soluble fiber slows digestion, it may slightly delay the absorption of certain nutrients — which is part of how it helps stabilize blood sugar and energy. For most vitamins and supplements like protein, creatine, and omega-3s, this is not a concern.
However, because soluble fiber can slow digestion and bind to certain compounds, it may reduce absorption of iron and some medications. To be safe, take fiber at least 2 hours before or after iron supplements or prescription medications unless your healthcare provider advises otherwise.
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.
