WHEN YOUR ROUTINE CHANGES

Sometimes your bowel routine just stops being routine.

Travel
Changing diet
Hard training
GLP-1 medication

Suddenly you’re more bloated, emptying your bowel less regularly, or waiting for coffee to get things moving.

That’s when getting enough effective fiber matters.

FiberBoom gives you 10g of psyllium husk in one bar — about two spoonfuls, already taken care of.

HOW PSYLLIUM WORKS

How psyllium works
in your body.

Psyllium is a natural, plant-based fiber that forms a soft gel when it absorbs water.

As it moves through your digestive system, that gel helps hold water in the stool, making it softer and easier to pass.

And with FiberBoom, 10g is already built into one bar.

One delicious bar. 10g of psyllium husk.

Give it time — your body might need a few days to adjust to psyllium.

THE SCIENCE

Psyllium has decades of research behind it.

The same ingredient inside FiberBoom has been studied across several areas of health.

01 / THE RESEARCH

Constipation

Psyllium absorbs water and increases the water content and volume of stool. Researchers have studied how this can help people with constipation.

More frequent bowel movements than with docusate, a stool-softening medicine.

View the research ↗

3.5 vs 2.9bowel movements per week

McRorie et al., 1998 · 170 adults with chronic idiopathic constipation · 5.1g psyllium twice daily vs 100mg docusate twice daily · 2 weeks. Week 2 means; p = 0.02. This was not a no-treatment comparison.

02 / THE RESEARCH

Cholesterol

Psyllium’s gel-forming fiber can reduce the reabsorption of bile acids.

Psyllium lowered LDL (“bad”) cholesterol across 28 controlled trials.

−0.33 mmol/Laverage LDL difference vs control

Jovanovski et al., 2018 · 28 randomized trials, 1,924 participants with or without high cholesterol · Median psyllium dose ≈10.2g/day · Trials ≥3 weeks. Pooled difference; 95% CI −0.38 to −0.27 mmol/L. The line shows the confidence interval.

03 / THE RESEARCH

Blood sugar

The gel created by psyllium can slow the movement and absorption of nutrients from food.

People with type 2 diabetes had a lower post-breakfast glucose response during psyllium treatment.

04 / THE RESEARCH

Fullness

Because psyllium absorbs water and expands, researchers have also investigated whether it can increase feelings of fullness after eating.

People reported greater fullness after breakfast with psyllium compared with placebo.

−21.7 → −14.9fullness score · higher means fuller

Higher means fuller: −14.9 is higher than −21.7. These are averages over 4.5 hours after breakfast, not hourly readings.

Brum et al., 2016 · Study 2, 40 healthy adults in the analysis · 6.8g psyllium before meals over 3 days · Table 4. Model-adjusted average scores across the 4.5-hour post-breakfast period; p = 0.002. SLIM scale −100 to +100. Industry-funded; no weight-loss outcome.

Research on psyllium preparations, not clinical trials of FiberBoom. Study doses, formats and populations differ; these results do not promise the same effect from a bar.

WHY FIBERBOOM?

Two spoonfuls.
No spoon.

Loose psyllium means measuring powder, mixing it with water and drinking it before it gets thick.

We wanted the psyllium, without that experience. So we put about two spoonfuls into one bar that actually tastes good.

No measuring. No mixing.
No thick psyllium drink.

Natural fiber
Low carb
Zero sugar

HOW TO ENJOY FIBERBOOM

One bar.
One big glass of water.

Start with one FiberBoom bar per day.

Enjoy it with a generous glass of water and make sure you’re drinking enough fluids throughout the day.

If you aren’t used to much fiber, give your body a few days to adjust.

FAQ

Questions?

How much psyllium is in one bar?

Each FiberBoom bar contains 10g of psyllium husk — about two spoonfuls.

How many bars should I eat?

Start with one bar per day. That’s the intended FiberBoom serving.

Should I drink water with it?

Yes. Psyllium absorbs water, so enjoy FiberBoom with a generous glass and stay well hydrated throughout the day.

Does one bar contain all the fiber I need?

No. FiberBoom provides 10g of psyllium husk, making a substantial contribution to your fiber intake. Fiber from a varied diet remains important.

Is FiberBoom a laxative?

No. FiberBoom is a food containing psyllium husk, not a medicine.

I’m taking a GLP-1 medication. Can I eat FiberBoom?

If you’re taking prescription medication, ask your doctor or pharmacist about adding psyllium and whether it should be separated from your medication.

Why psyllium rather than another fiber?

Psyllium is unusual because it absorbs water and forms a viscous gel — the physical property behind many of its best-studied effects.

Where can I see the scientific evidence?

Every science section links directly to the research behind it.
