A note from an ER doctor

I read the labels on 12 gut supplements. Here are 10 things they count on you not to check.

Four in ten adults have a gut problem where every test comes back normal. The aisle built for them is aimed at the wrong target.

8 actives, every dose printed Third-party tested 12-week money back Free shipping

MGB+ Clear with artichoke leaf, ginger, garlic and saffron — MGB+ Clear. Eight actives, every amount on the label.

Most of them are not lying. They are counting on you not to do the arithmetic.

The gut aisle sells you things that act on what is in the tube. Almost nothing sold there acts on the signal that moves it.

01.The wrong target

Everything on that shelf acts on what is inside the tube.

Fiber adds bulk. Probiotics add bacteria. Enzymes break food down. Magnesium pulls in water. All contents.

Your colon does not move on its own. A nerve tells it to. That signal is the part that goes wrong in most people who did everything right and are still symptomatic.

You can change what is in the tube for years and never touch the thing that moves it.

02.The fiber trap

If fiber fixed you, close this tab.

I mean that. Fiber helps a lot of people and I recommend it constantly.

But there is a group it makes worse. More bulk into a tube that is not moving is more pressure, more stretch, more of the swelling you were trying to fix. So people double the dose, and the afternoons get worse.

Fiber adds bulk. It does not add signal.

Swollen and flattened by mid-afternoon — The 3pm version of doing everything right.

03.The diagnosis nobody gives you

"Everything looks normal" is a finding, not a dead end.

4 in 10

adults worldwide have a disorder of gut-brain interaction. The plumbing is fine. The signaling between the gut and the brain is not.
Rome V consensus, 2026

Normal scope. Normal bloodwork. Normal imaging. You get told nothing is wrong and you go home still bloated.

Normal tests are not a mystery. They are the answer. They just do not come with a plan attached.

04.The dose gap

The ingredient is real. The amount usually is not.

A bottle names an ingredient with real research behind it, then includes a fraction of what the research used.

The trick, in two lines

What a typical label carries50 mg

What the study it cites actually used300 mg

Fifty milligrams of something trialed at three hundred is not a smaller version of that study. It is a different product wearing the study's clothes.

Two minutes to check. Find the study the brand points to, find its dose, read the panel on the back. If the numbers do not match, you are paying for the name.

05.The blend dodge

"Proprietary blend" is where the dose hides.

Six ingredients in a row, one number next to all of them. Legal, and unreadable.

Supplement Facts

Serving size2 capsules

Digestive Support Matrix™800 mg

Ingredient one? mg

Ingredient two? mg

Ingredient three? mg

The expensive one you bought it for? mg

Daily Value not established.

Ingredients are listed by weight, so the first is doing most of the work and the last may be a dusting. You cannot tell which.

If the amounts are not broken out, assume the cheapest one is most of the blend.

06.The cheap form

Most B1 on a label is the form that absorbs worst.

Thiamine shows up on almost every label as thiamine hydrochloride or mononitrate. The cheap salts. Fine at food-level amounts.

Push the dose up and the percentage you absorb falls off steeply. A large share of what you paid for passes straight through.

Clear uses allithiamine at 75 mg. In head-to-head human studies the lipid-soluble forms reach higher blood levels than the plain salts at the same dose.

Allithiamine, a lipid-soluble form of vitamin B1

07.The one nobody stocks

Your body makes a compound to quiet nerve signals. Almost nothing on that shelf contains it.

PEA, short for palmitoylethanolamide. You produce it. It is one of the ways your body turns down an overactive nerve signal on its own.

More than six hundred published studies. Not exotic, not new. Just expensive to put in a bottle at a real dose, which is why it is almost never there.

Clear has 300 mg. The most costly line on the panel and the one I would not cut.

08.The open panel

Every active in Clear is printed at its full amount. No blends.

Eight ingredients, eight numbers. Three do the heavy lifting. Five back them up.

Artichoke leaf extract

150 mg

Bitter plant compounds that wake up bile flow and get meals moving. Works closest to the bloat.

Allithiamine

75 mg

A lipid-soluble form of vitamin B1, originally isolated from garlic. Absorbs far better than the plain salts in head-to-head human studies. Nerve cells depend on B1 to make energy, and the gut runs on nerve signal.

PEA (Palmitoylethanolamide)

300 mg

Your body already makes it. It calms overactive nerve signals. Over 600 published studies.

Ginger extract 100 mg
The most-studied root for a settled stomach.
Magnesium glycinate 100 mg
Gentle magnesium that calms the gut-brain loop.
Shatavari root extract 150 mg
An adaptogen for the stress side of digestion.
Saffron extract 30 mg
Studied for mood and focus on foggy days.
Lithium orotate 5 mg
A trace mineral at mineral-water levels. Not a drug dose.

I would rather lose a sale to a spreadsheet than win one with a blend.

09.The part nobody sells

Twelve weeks is the honest timeline, and saying so costs me sales.

A supplement that promises three days outsells one that says three months. I am telling you three months anyway.

Weeks 1 to 2Meals feel lighter. Artichoke and ginger work close to the plate. Most people notice timing before they notice size.
Weeks 3 to 6The signal layer builds. B1, PEA and magnesium do slow, steady work. This is usually where the pattern starts to shift.
Weeks 7 to 12The new normal. By the end of this window you know, one way or the other.

That is why Clear ships as a 90-day protocol. It is not an upsell, it is the length of the trial. The money-back window runs a full 12 weeks from delivery.

Common questions

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 doesn't work for me?

Then it's free. Email us any time within 12 weeks of delivery and we refund your first order, up to three bottles. Keep them.

Should I stop my fiber?

If fiber helps you, keep it. Clear isn't a fiber. It works on the signal, not the bulk. Many people take both. Ask your doctor.

How do I check a label myself?

Find the ingredient the brand leads with. Find the study they point to and the dose it used. Then read the Supplement Facts panel on the back. If the panel lists a fraction of the studied amount, or lumps everything into one blend number, you have your answer. Do it to Clear too. That is why every amount is printed.

Does it help with occasional constipation?

Clear supports the motility signal that keeps digestion regular. It is not a laxative, and it doesn't treat chronic constipation or any disease. If things are severe, new, or changing, see your doctor first.

Can I take it with my medications?

The ingredients are well tolerated. Still, check with your prescriber, especially for blood thinners, lithium, MAO inhibitors, or anything that affects brain chemistry. Clear has a trace of lithium orotate (mineral-water level, not a drug dose). If you take prescribed lithium, ask first.
