Product Description
Your gut does more than digest food, it absorbs the nutrients that fuel your training, regulates inflammation, and even influences your energy levels on race day. Fiber is the foundation of all of it, and most athletes fall significantly short of daily targets when they're eating for performance rather than general health with variety.
Momentous Fiber+ gives your gut what it needs to work with you, not against you.
This is a multi-source fiber formula built specifically to cover every angle of digestive and metabolic health — in one clean, unflavored scoop. From supporting your general health to the absorption of the fuel you take on.
Multi-Source Coverage Formula – Fiber+ combines psyllium husk, resistant potato starch (Solnul®), and rice bran hull, three distinct fiber types that each do something different. Together they support regularity, feed your gut microbiome, and improve how your body handles carbohydrates.
Fuel for Your Gut Microbiome, Not Just Digestion – Resistant starch acts as a prebiotic — food for the beneficial bacteria that live in your gut. When those bacteria ferment resistant starch, they produce short-chain fatty acids (SCFAs), compounds that strengthen the gut lining and support a healthy inflammatory response after hard training.
NSF Certified for Sport – Every batch of Fiber+ is independently tested and NSF Certified for Sport, so you know exactly what you're getting. No banned substances, no fillers — just the ingredients on the label.
How to Use Momentous Fiber+
Daily Use: Mix 2 scoops (11.6g) into 8–12 oz of water or your preferred beverage once daily. Unflavored, stacks easily into a shake, smoothie, or just water.
Consistency is Key: Take it at the same time each day to build regularity and support sustained microbiome diversity.
Pro Tip: Start with 1 scoop for the first week if you're new to higher fiber intake, then build to the full 2-scoop serving to minimize any initial digestive adjustment.

Momentous Fiber+ FAQ's
Everything you need to know before getting started.



Take Fiber+ once daily, at whatever time fits your routine. Many athletes prefer it in the morning with breakfast or as part of a post-workout shake. Consistency matters more than timing — daily use is what builds lasting gut health benefits.
Most athletes notice improved digestive regularity within 1–2 weeks of consistent use. Microbiome benefits, like better nutrient absorption and reduced GI distress during training, tend to build over 4–6 weeks of daily use.
Resistant starch is a type of fiber that passes through the small intestine undigested and ferments in the large intestine, feeding beneficial gut bacteria. This fermentation produces short-chain fatty acids that support the gut lining and help regulate inflammation — both critical for athletes doing repeated hard training.
Yes. Choose Unflavored to mix invisibly into any shake or smoothie, or go Cinnamon for a subtle flavor boost — both blend cleanly without affecting texture.
Yes. Fiber+ is NSF Certified for Sport, meaning it's independently tested and verified free of banned substances. It's safe for athletes subject to drug testing at any level.
