How it works
Vitamin B1 is the fuel your nerves and energy systems run on. The catch: standard B1 is water-soluble, so most of it gets flushed out before it ever does its job. That's why drugstore B-complex rarely moves the needle.
Allithiamine is a fat-soluble form of B1 that actually crosses into your cells — including the nerves that run your gut.
Built on the MGB+ core — magnesium glycinate + lipid-soluble B1 — to keep your brain and gut talking.
Capsule dissolves in the small intestine.
Allithiamine crosses into the cells (where standard B1 can't).
Reaches the gut nerves and energy enzymes that need it.
You feel steadier digestion, clearer focus, and even energy.
Simplified mechanism. See ingredient cards for full citations.
THE BRAND THESIS
Every MGB+ formula is built on the same foundation. Pattern-matched bioactives are layered on top to support the targeted phenotype, the symptom signature, and the metabolic context that brought you here.
Molecule 1
Magnesium bisglycinate
Drugstore magnesium oxide is poorly absorbed and known for sending people to the bathroom. Magnesium glycinate is bound to an amino acid the body recognizes, which means more of it lands where it works: smooth muscle, nerve signaling, the stress axis.
Molecule 2
Allithiamine (TTFD-class)
Standard thiamine is water-soluble. Most of it gets flushed before it reaches the cells that need it. Lipid-soluble allithiamine crosses membranes the body actually uses, reaching the enteric nerves that run digestion.
Every ingredient. Every dose. Every reason. No proprietary blends, no hiding behind a mix.
Lipid-soluble B1 (TTFD-class)
Crosses where standard thiamine cannot. Fuels the enteric nerves that drive gut motility and the metabolic enzymes behind steady energy.
75 mg is the threshold dose where lipid-soluble B1 shows nerve-conduction effects in the published literature. Higher doses do not add benefit at the gut-brain target.

Magnesium bisglycinate (chelated)
The most absorbable form of magnesium, bound to glycine. Supports smooth muscle relaxation in the gut and steady stress response.
100 mg of elemental Mg from glycinate hits the daily floor for nerve and smooth-muscle support without crossing into laxative territory.

Endogenous fatty acid amide
An on-demand inflammatory modulator the body already makes. Helps the gut settle without external suppression.
300 mg is the dose used in the modern PEA literature for visceral comfort. Lower doses lose signal.

Crocus sativus, 4:1 standardized
Supports stress tolerance and the gut-brain feedback loop on hard days.
30 mg of 4:1 saffron matches the dose range in studies on mood and stress resilience without sedation.

Zingiber officinale, 20% gingerols
Fast-acting post-meal comfort. Supports gastric emptying so food does not sit and trigger discomfort.
Standardizing to 20% gingerols ensures the active compound dose lands consistently across batches.

Lithium bound to orotic acid
Trace mineral support for neuronal signaling. Helps the brain-gut axis communicate cleanly.
5 mg is the trace nutritional dose, not the prescription dose. Decades of safety data at this range.

No "feel it tomorrow" promises. Here is the realistic arc, week by week.
Most people notice steadier mornings and less post-meal drag. Energy curve through the afternoon evens out.
Bloating cycles get shorter. Mental clarity becomes the change other people notice on you, not just one you notice on yourself.
Decision point for the guarantee. If the change has not stuck by now, email us. We refund. You keep the bottles.
Foundation phase complete. Most subscribers stay on indefinitely as the floor of a maintained routine.
Most subscribers take MGB+ Clear indefinitely as the floor of their routine. No loading phase, no taper, no cycle off.
Day 60 is your decision point. If nothing has shifted by then, our 60-day guarantee returns your money. Keep the bottles.
PROOF, NOT PROMISES
Peer-reviewed studies that inform the doses on the MGB+ Clear label.
Review of lipid-soluble thiamine forms (allithiamine, benfotiamine) establishing their superior bioavailability versus water-soluble B1, including nerve-conduction and enteric signaling endpoints.
Chelated magnesium glycinate supports smooth muscle regulation and HPA-axis modulation without the laxative profile of magnesium citrate or oxide.
PEA as an endogenous ALIAmide modulates inflammatory tone in gut tissue. The 300 mg daily dose used in modern literature matches the dose in MGB+ Clear.
Saffron supplementation reduced inflammatory markers and supported metabolic resilience in clinical trials. The 30 mg of 4:1 saffron in MGB+ Clear matches the mood and stress-resilience dose range.
Umbrella review confirming ginger extract at 100 mg (standardized to 20% gingerols) delivers reliable prokinetic and anti-nausea effects across dozens of trials.
Study selection is for mechanism context. None of these studies were run on MGB+ Clear itself. Citations are curated by the BellyMD research team.

BUYER QUESTIONS
The questions you actually have.
You can. Drugstore magnesium oxide costs less and absorbs poorly, which is why it has a reputation for sending people to the bathroom. The magnesium glycinate in this formula is bound to an amino acid the body recognizes, so more of it lands where it works. We also pair it with lipid-soluble B1 and the targeted botanicals on the supplement facts. Buying those separately costs more than the bundle and you still need to figure out the doses.
If your current magnesium is doing what you need, keep it. MGB+ Clear is built for people whose stress and gut symptoms are linked, and who need the lipid-soluble B1 alongside the magnesium. You can also take this as a swap, not an add. Two capsules a day, not on top of another magnesium.
Generally yes, but always run new supplements past your prescribing clinician. Magnesium can affect absorption of some medications when taken at the same time of day, so we recommend separating doses by two hours when possible. If you are on a blood thinner, mention the ginger and turmeric content specifically.
Most people notice the first signal in week two. The full picture, energy, regularity, less of the post-meal drag, lands somewhere between week four and week eight. Day 60 is your decision point. If nothing has shifted by then, the guarantee returns your money.
Email support@belly-md.com within 60 days. We send the refund. You keep the bottles. Unopened product is returnable within 365 days as a secondary window. We do not require photos, justifications, or a return.
Yes. Every ingredient was selected for daily use at the dose listed. There is no loading phase, no taper, no cycle off. Most subscribers take it indefinitely. The formula was built to be the floor of a routine, not a 30-day fix.
Gummies require sugar binders that compete with the active ingredients and rarely deliver clinically meaningful doses. Powders work but introduce taste and mixing issues that kill compliance. Capsules let us hit the doses on the label without filler trade-offs. Two a day with food, done.

A note from the founder
Dr. Rick Pescatore, DO · Founder & Chief Medical Officer
I spent most of my career in emergency rooms. You see a lot in an ER, but you also see the same thing over and over. Fatigue nobody can explain. Stomachs that stopped working after some infection two years ago. Brain fog in thirty-somethings who used to be sharp.
Every one of them had been told it was anxiety, or gluten, or nothing. Most of the time it was neither. It was two nutrients the gut and the brain both need — magnesium and B1 — in forms the body could actually use.
I built MGB+ Clear because I got tired of writing discharge papers that didn't help. This is the formula I wanted to hand those patients. Lipid-soluble B1 so it actually crosses. Chelated magnesium so it actually absorbs. The rest of the stack, targeted for the gut-brain phenotype that kept walking into my ER.

FOR THE CLINICALLY CURIOUS
ROME IV framing, ICD-10 mapping, and the full mechanism breakdown for clinicians and clinical-lane buyers.
Diagnostic framing (ROME IV)
MGB+ Clear is positioned for adults with Rome IV functional gut-brain interaction patterns including functional bloating, IBS-mixed, and slow-transit constipation. The formula targets visceral hypersensitivity and motility dysregulation through allithiamine-driven enteric nerve support.
Relevant ICD-10 codes
| Code | Name | Relevance |
|---|---|---|
| K58.9 | IBS, unspecified | Irritable bowel syndrome, mixed or unspecified subtype |
| K58.0 | IBS with diarrhea | IBS-D presentations |
| R14.0 | Abdominal distension (gaseous) | Functional bloating presentations |
| K59.00 | Constipation, unspecified | Slow-transit and functional constipation |
| K30 | Functional dyspepsia | Post-prandial distress overlap |
Mechanism of action
Lipid-soluble thiamine (allithiamine) crosses the intestinal barrier and supports enteric nervous system signaling. Magnesium glycinate provides chelated elemental magnesium for smooth muscle regulation. PEA modulates the endocannabinoid-like ALIAmide pathway. Saffron, lithium orotate, and shatavari layer gut-brain axis modulation. Ginger and artichoke support motility and bile flow.
