Silver Fern™ Brand

You Asked and We Delivered — A Fiber That Can:

⚡ Be used at ANY step of your gut protocol — cleanup, repair, rebuild, or maintenance^*

⚡ Help support a healthy gut lining, beneficial bacteria growth, and balanced immune response^*

⚡ Support fullness and metabolic wellness goals^*

⚡ Move you meaningfully closer to the 25–38 g daily fiber target — without choking down 6 different products^*

Feed the Whole Gut, Not Just One Part of It^*

Ultimate Fiber contains 3 clinically studied prebiotic fibers.^*

Each at its clinical dose.^*

Each fermenting and feeding the whole gut at different times.^*

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.^*

As you may know, different species of good gut bacteria eat different fibers. And they live in different stretches of the colon, spread from front to back.

Silver Fern’s Ultimate Fiber is built for exactly that.

Three structurally different prebiotic fibers in one scoop, each one feeding a different group, each one at the dose used in the human research behind it.^*

FiberSMART® feeds beneficial bacteria selectively, without disturbing the rest.^*

Inavea™ keeps working further down.^*

Solnul® feeds Bifidobacterium and Akkermansia specifically.^*

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.
