“I have struggled with IBS like symptoms for years. Fiber seemed to help. I took the Clear supplement and noticed such a significant change and calmness in the gut, I recommended it to family with the same issues.”
One in four. Nobody was checking.
New research measured vitamin B1 in 286 hospitalized patients who do not drink. One in four were deficient, and the commonest sign was not confusion. It was no appetite. Clear is built on allithiamine, a better-absorbed form of B1, for the gut-brain signal that runs on it.
The physician’s note behind the video
Some common prescriptions block the B1 transporter.
Standard vitamin B1 (thiamine) is water-soluble. To get from the gut into the body it rides a transporter in the gut wall called ThTR-2. In 2020, researchers at UCSF screened 1,360 compounds against that transporter. 146 blocked it.
Eleven were prescription drugs that reach the gut at concentrations high enough to matter, by the study’s own threshold. The list is ordinary: metformin, sertraline, amitriptyline, amoxapine, hydroxychloroquine, trimethoprim (half of Bactrim), verapamil, quinidine, quinapril, and penicillamine. In hospital records, people taking these drugs had lower blood thiamine than people who were not, most clearly in those already at risk.
Why a fat-soluble form of B1 is different. Allithiamine is a fat-soluble form of vitamin B1. Because it is fat-soluble, it passes through cell membranes on its own instead of relying on the transporter. It is the B1 in MGB+ Clear, at 75 mg per daily dose, printed on the label.
An honest note. Clear is a daily supplement that supports your B1 intake. It is not a medicine, it does not prevent or treat any condition, and it does not replace, change, or make any prescription safer. Keep taking your medication exactly as prescribed, and talk with your prescriber before adding anything. Rick Pescatore, D.O.

Formulated by Rick Pescatore, DO · Board‑Certified Emergency Physician
Eight active ingredients. Every dose on the label.
No mystery blends. Every ingredient and its exact amount, listed right here.
A well-absorbed form of vitamin B1allithiamine
75 mgA fat-soluble B1 that absorbs far better than the ordinary, water-soluble kind. Your body converts it into the active form your cells actually run on. The core of every MGB+ formula.
A 2026 Frontiers in Nutrition study confirmed it works as active B1 in living animals.
Calming magnesiummagnesium glycinate
100 mgA well-absorbed magnesium that helps quiet an overactive gut-brain loop, without the laxative effect of cheaper forms.
PEApalmitoylethanolamide
300 mgA calming molecule your body already makes. It helps turn down the overactive nerve signals behind fog and an oversensitive gut. Clear's biggest helper.
Artichoke leaf5% cynarin
150 mgBitter plant compounds that get digestion moving after meals, for lighter afternoons and less bloat.
AllithiamineFat-soluble B1 that absorbs far better than ordinary B1.75 mg
Magnesium (as magnesium glycinate)Well-absorbed magnesium that helps quiet an overactive gut-brain loop.100 mg
PEA (palmitoylethanolamide)A molecule your body makes; studied for calming overactive nerve signals.300 mg
Artichoke leaf extract (5% cynarin)Bitter compounds that ease digestion and post-meal heaviness.150 mg
Shatavari root extract (4:1)An adaptogen for the stress side of digestion, where tension and the gut feed each other.150 mg
Ginger root extract (20% gingerols)Concentrated ginger, the most-studied root for a settled, comfortable gut.100 mg
Saffron extract (4:1)Concentrated saffron, studied for steady mood and sharper focus on foggy days.30 mg
Lithium (as lithium orotate)A trace mineral at the level found in some mineral water.5 mg

From the public comments on Dr. Rick’s videos
I’ve been taking B1 for over three weeks now and my daily extreme fatigue and brainfog has decreased so much already!
Within days of starting B1, I feel so alert and no brain fog. Before, I had to nap everyday but now, no naps needed.
I’ve been taking B1 and a magnesium supplement every morning, and I have never been so regular in my life!
Came back to thank you. I saw this video and purchased B1 the next day. After just a few days, I feel so much better.

+ The quiet part
There is no sales force for vitamin B1.
A few unglamorous molecules keep the gut-brain wiring supplied. Magnesium glycinate. A well-absorbed form of vitamin B1. No drug company advertises them, because no drug company owns them, so the knowledge stayed inside medicine.
MGB+ is that knowledge, dosed properly and put on a label you can read. It is what a physician gives his own family.
Why one formula covers all three.
Your gut and brain run on a single nerve line, the gut-brain axis, and that line needs fuel. Clear feeds it the absorbable form of B1, with magnesium alongside.
What to expect, week by week
Week 1Get consistentTake it daily with food. A few people notice vivid dreams or brief lightheadedness the first days as the body adjusts to the absorbable B1. Normal and temporary. A full meal helps.
Weeks 2 to 4Watch your patternHow heavy afternoons feel. How often the fog rolls in. How the 3 p.m. dip lands. MeNome keeps the record, two quiet minutes a night, so you are not relying on memory.
Weeks 4 to 8The turnThis is when the pattern usually shifts: more light afternoons than heavy ones.
Weeks 8 to 12Decision pointBetter? Keep going. Not better? Your first order is free.
Two patterns? Save on the pair
Complete the pair.
Many people run more than one pattern. Any two formulas together cost less than buying them one at a time, on one subscription cadence.

Read the transcript
Your gut and your brain aren't two separate systems. They're one wired together. And when that system gets what it needs, you feel it on both ends. You have a clearer head, steadier energy, and digestion that you don't have to think about.
That's the job of MGB+ Clear, especially if you're prone to foggy afternoons, the mid-afternoon crash, or dinners that just kind of sit there and don't move through. It starts with the ingredient. I built this movement around allithiamine. It's a fat-soluble form of B1, highly absorbed and first discovered in garlic.
Your nerves run on B1. It's how you turn food into energy, but the ordinary multivitamins have a water-soluble form that struggles to get to the mitochondria and the brain. Allithiamine penetrates to where the gut-brain connection actually lives. It has 75 milligrams, which is a meaningful dose, and with it, 100 milligrams of magnesium glycinate.
That's the gentle form on the stomach that's actually absorbed, and it's optimized to match the B1 within. This one is chosen for your nervous system. There are five more ingredients here with very specific jobs. Artichoke leaf and ginger, two of the best-studied botanicals for keeping digestion moving comfortably.
There's PEA, 300 milligrams of a compound that your own body makes to quiet, noisy nerve signaling. And saffron, at a real dose, studied for mood and mental clarity. There's shatavari, which has been used for centuries for digestive comfort. Finally, lithium orotate, an important addition.
It's a tiny fraction of what's used in prescription medicine close to what shows up in naturally occurring drinking water, and it's linked with emerging literature supporting its use in brain health and longevity. Take all of this with food. The B1 absorbs better with a meal, and you get 12 weeks to feel the difference. If you don't, we refund your whole first order, and you keep the bottles.
There are eight ingredients in one system. That's MGB+ Clear.
Built by a doctor. Reviewed by an independent clinical board.
I am an ER doctor. I kept meeting smart people whose labs were normal but whose afternoons were not. The fog, the 3 p.m. wall, the bloat that shows up after lunch. Clear is what I wanted to hand them.

The things people ask first.
Clear is a gentle daily supplement, but it is not a substitute for your doctor. If you take prescription medication, are pregnant or nursing, or manage a health condition, check with your physician before starting. Every ingredient and dose is on this page so you can share the full list.
Most people notice small shifts between weeks 2 and 4, with a clearer signal by weeks 4 to 8. Give it a fair 12-week test. It is a slow-build formula by design.
Only subscription plans renew, and the page always tells you which one you picked. Skip, pause, or cancel anytime in your account, with no fees and no phone calls. One-time orders never renew.
Simple. Take it daily and give it up to 12 weeks from delivery. If you are not better off, email support@belly-md.com and we refund your first order, up to three bottles. Keep them, nothing to ship back. One guarantee per customer, because we mean it.
Two capsules a day with food. Each bottle holds 60 capsules, a 30-day supply.
Same formula, same two capsules a day. The 12-week protocol is three bottles in one box, one charge, and all three bottles are covered by the guarantee. Month to month is one bottle at a time. A single bottle is a 30-day trial that never renews. A month tells you if you tolerate it. Twelve weeks tells you if it worked, so most people start with the protocol.
Every first order includes the Welcome Kit, free: your formula's printed Protocol Cards (dosing, timing, and what to notice, week by week) plus a couple of BellyMD extras. The 12-week protocol box also carries the pocket evidence booklet. Subscriptions get the kit with their first shipment.
Try it for 12 weeks. Not helping? Your first order refunded, up to three bottles. Keep them.
