Ultimate Fiber is NOT your average fiber powder

Ultimate Fiber by Silver Fern™ delivers three clinically studied prebiotic fibers, used at the same levels shown in research, supported by more than 26 published studies, and formulated to support gut balance in ways most fiber powders don’t even attempt.^*

With 15 grams of low-FODMAP fiber per serving (yes, tolerable even for the “bloat-sensitive” crowd), Ultimate Fiber may be exactly what your gut has been missing.^*

Why Does Ultimate Fiber Hit the Bullseye?

➤ 90% of Americans don’t meet their daily fiber needs
(Recommended: 25g daily for women and 35–38g daily for men. Reality? FAR below that.)

➤ Insufficient fiber intake has been linked to major negative shifts in gut microbiota composition.¹ ²

Most fiber supplements only bulk the stool…

Ultimate Fiber delivers clinically studied doses of fibers shown to support:

✔ Microbial balance and diversity^*
✔ Gut lining integrity^*
✔ Healthy immune signaling in the gut^*
✔ Comfortable daily regularity^*
✔ Satiety and healthy eating patterns^*
✔ Metabolic wellness markers and short-chain fatty acid production^*

In other words — this is fiber that does something.

The Science Behind Ultimate Fiber

Resistant Dextrin from non-GMO corn (Sourced from France)

USER BENEFITS^*

• Supports satiety and fullness during calorie-controlled eating^*

• Promotes beneficial fermentation without rapid gas production^*
• Supports microbial enzyme activity and healthy fermentation patterns^*

CLEAN LABEL ATTRIBUTES

✔ Non-GMO
✔ Grain-free (Made from purified resistant maize dextrin, which is an isolated fiber extracted from maize starch — not from the whole grain (which includes bran, germ, and endosperm). Since it does not contain the structural components of whole maize grain or proteins typically associated with grain allergens or gluten-like responses, it does not qualify as a “grain ingredient.”)

✔ Low glycemic response
✔ Highly soluble / easy to mix
✔ Clinically evaluated in 15+ human trials
