When Fiber Makes It Worse
Bloated by 3pm. Stuck and sluggish. You added fiber and water, and it got worse. Here is what is really going on, and the 90-day plan I built for it.

N° 01The patient I keep seeing
She did everything right. It got worse.
She is 41. By 3pm her stomach is so swollen her jeans stop fitting.
Her doctor gave her the standard advice: more fiber, more water. She did it all. The bloating got worse. The gas got worse. Everything slowed down.
Her tests were normal. Nothing was “wrong.” She just felt swollen, slow, and foggy every single day.
I see her in the ER every week. Different faces, same story. Almost all of them are still taking the fiber that is not working.

Your colon does not move on its own
Nerves tell it when to move. Digestion is not plumbing. It is signaling. Your gut muscle takes orders from a nervous system wired straight into your brain.
One signal, three symptoms. In 2026 the Rome Foundation, the group that sets the world standards here, published new numbers on how common this is.
42%
of adults have a gut-brain disorder.

8.9%
have IBS, nearly twice the old number.

Fiber adds bulk. It does not add signal
Fiber is good advice for many people. If it fixed you, keep taking it.
But fiber only adds bulk. When the signal is idling, more bulk just sits in a slow gut. It ferments. It stretches. It presses outward. That is why the standard advice made you feel worse.
Enzymes and probiotics have the same problem. Fine products. None of them talk to the wiring.
“Fiber adds bulk. It does not add signal. If the signal is the problem, more bulk just means more to sit there.”
Rick Pescatore, DOI built Clear for the signal
Eight ingredients. Three do the heavy lifting. Five back them up.
Bitter plant compounds that wake up bile flow and get meals moving. It works closest to the bloat: less sitting, less stretching, lighter afternoons.
A fat-soluble form of vitamin B1, originally isolated from garlic. Plain B1 absorbs less and less efficiently as the dose climbs. This form absorbs far better in head-to-head human studies. Nerve cells depend on B1 to make energy, and the gut runs on nerve signal.
Your body already makes PEA. It calms overactive nerve signals. Over 600 published studies. Most Americans have never heard of it.
The most-studied root for a settled stomach.
Gentle magnesium that calms the gut-brain loop.
An adaptogen for the stress side of digestion.
Studied for mood and focus on foggy days.
A trace mineral at mineral-water levels. Not a drug dose.
The full package insert, with precautions and the evidence behind each ingredient, is on the MGB+ Clear page.
Why 90 days
Nerves change slowly. One bottle is a taste. The protocol is the point.
Meals feel lighter
Artichoke and ginger work close to the plate.
The signal layer builds
B1, PEA and magnesium do slow, steady work.
The new normal
This is the window that matters.
That is why Clear ships as a 90-day protocol, and why the refund window is 12 weeks. They match on purpose: you run the full protocol at zero risk. If it does not shift, you get every dollar back, and you keep the bottles.

Common questions
Why 90 days?
Nerve-level change takes weeks, not days. Artichoke and ginger help early. The signal layer builds over two to three months. The protocol matches the biology. The guarantee matches the protocol.
What if it does not work for me?
Then it is free. Email us any time within 12 weeks of delivery and we refund your first order, up to three bottles. Keep them.
Can I keep taking fiber?
If fiber helps you, keep it. Clear works on the signal, not the bulk, so the two do not compete. If fiber is what made things worse, you have your answer.
Can I take it with my medications?
Usually, but check first. Leave four hours between a thyroid medication and Clear, because of the magnesium. If you take prescription lithium, a blood thinner, or anything for kidney disease, ask your clinician before you start.
Is the subscription a trap?
No. Skip, swap or cancel any time from your account. No calls, no contracts.
