Use this formula when your symptoms travel together and do not fit one clean box.
Gut-brain symptoms often involve signaling, motility, sensitivity, and cellular energy. MGB+ starts with lipid-soluble B1 and magnesium glycinate, then adds formula-specific actives based on the symptom pattern.
This page is focused on your gut-brain pattern.

BellyMD has entered into a research option agreement with a major U.S. research university around blood biomarkers and diagnostic methods for cannabinoid hyperemesis syndrome. The agreement gives BellyMD an option to negotiate an exclusive license in the field of use.
Our educational framework is informed by Rome Foundation diagnostic concepts and ACG/AGA guidance on disorders of gut-brain interaction. BellyMD supplements are not diagnostic tools and are not intended to treat disease.

The two molecules that do most of the work. Real doses. Real evidence. Every spotlight links to the PubMed-verified pages behind it.
Real customer messages, in their own words. Shared to show the kinds of patterns customers report while using Clear, not to promise a specific result.

Four steps that explain what MGB+ actually does. No jargon, no hype, just the mechanism.
Most people show up with symptoms that travel together. Bloating, brain fog, fatigue, cyclical nausea. They do not always fit cleanly into one diagnostic box. The pattern is the signal that helps guide the formula.
The gut and brain talk in both directions. Symptoms that start in the gut can affect the brain. Signals from the brain can change how your gut moves, feels, and responds. The right support starts by recognizing which direction the trouble seems to be running.
Clear supports the bloating-and-brain-fog pattern. Cool supports the upper-gut layer. Calm supports the morning gut. Take the quiz or read each page. The pattern guides the pick.
Track honestly. Adjust the obvious inputs: sleep, caffeine, meal size, stress load. Try the formula consistently, then reassess the pattern over time.
Most B1 supplements use thiamine HCl. MGB+ uses allithiamine, a lipid-soluble B1 derivative, as part of the MGB+ Core with magnesium glycinate. Clear then layers in targeted actives for the bloating-and-brain-fog pattern.
No proprietary blends. No fairy dust. Eight active molecules, each at the serving dose printed on the bottle.
Magnesium bound to glycine. A well-tolerated form used for nervous-system, muscle, and digestive comfort support.
A molecule your body already makes. Studied for inflammatory balance, nerve sensitivity, and visceral signaling. 600+ published studies.
An adaptogen used for centuries in Ayurvedic medicine. Studied for stress-system and gut-brain rhythm support.
Bitter compounds used for digestive comfort, meal tolerance, and post-meal heaviness support.
Concentrated to its active compounds. Studied for digestive comfort, queasy days, and motility-related support.
A lipid-soluble form of vitamin B1 used as the B1 side of the MGB+ Core. Paired with magnesium glycinate as the shared base of the formula.
Studied for mood support and cognitive function. The crocins and safranal are the active compounds doing the work.
Trace-dose lithium. The level found in mineral water, not a fraction of psychiatric dosing. Studied for steady mood and neuronal health.

The stack many people build for the bloating-and-brain-fog cluster. Multiple bottles, overlapping doses, no clear strategy. Or one bottle of Clear.
About $61 a month not spent. One bottle, eight ingredients, one ship date.
DGBI rarely lives in one zone. The formulas are built to stack — and they share a single subscription cadence. Save 15% with any Duo, 20% with the Trio.
For the days your gut runs hot. Upper-gut burn, post-meal heaviness, the heavy-stomach pattern. 15% off both bottles.
For sensitive stomachs and wired evenings. The morning side of the gut-brain pattern. 15% off both bottles.
All three formulas. Save 30% vs three individual subscriptions.

I'm Rick Pescatore. ER doctor. Editor-in-chief of Emergency Medicine News. The emergency department is where I first saw the pattern. It's not where the pattern lives. Bloating. Brain fog. Fatigue that doesn't lift. The gut that runs the day. The labs come back normal. The scans come back normal. The medications never quite fit.
MGB+ is built around that pattern, not around the symptoms it produces. Three formulas. Real doses. Every ingredient on the label. It's the protocol I'd run on my own family. It's the protocol I run on myself.
Some people report noticing a shift in the first week. For many, the pattern is easier to judge after two to four weeks of consistent use. Bigger baseline changes are usually assessed over eight to twelve weeks. If you are at week six and feeling nothing, hit reply on the welcome email. Rick reads every one.
Yes. One click in your account. No retention call, no email gauntlet. Skip a month, swap formulas, or pause indefinitely. All from the same screen.
Twelve weeks is the window we use to judge whether the formula is a fit. If your pattern has not shifted by then, email us within 90 days of your first order and we refund it in full. No bottle return required. We may also help you switch to a different formula if your pattern points somewhere else.
US cGMP facility. Third-party tested. Every ingredient and dose is disclosed on the bottle and the open-formula section above. We use the forms selected for the MGB+ system: allithiamine as lipid-soluble B1 and magnesium glycinate as the magnesium side of the core.
