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 mixed gut-brain patterns that move between formulas.

No complicated schedule. No fixed order. Built to fit the way you already eat.
Not two of each. Two total — pulled from whichever formula matches what your day is doing.
With food makes them gentler on the stomach. Three capsules a day is the maximum.
The three formulas target different sides of the gut-brain axis. A bloating-and-brain-fog day might be 2 Clear. A heavy-meal evening might be 1 Cool. A queasy morning might be 1 Calm. A mixed day might be 1 of each.
Pay attention to what shifts. The Trio is built for flexibility, not a fixed schedule.
Some shifts come within days: brain fog, sleep quality, morning queasiness. The full gut-brain pattern shift takes the full window.
Track honestly. That's why our guarantee runs 12 weeks.
If you take prescription medications, are pregnant or nursing, or have a chronic medical condition, check with your doctor before starting any new supplement.
Self-reported outcomes from Trio customers. Three formulas working in concert.
Aggregated from a Klaviyo customer survey, n=204 respondents, May 2026. Self-reported, not a clinical trial.
Your gut and brain are in constant conversation. The vagus nerve, the enteric nervous system, and the gut microbiome signal up. The brain signals back down through hormones, inflammation, and stress chemistry. When that conversation runs smoothly, you feel clear, comfortable, and steady. When it doesn't, you get the pattern: bloating, brain fog, fatigue, queasy mornings, sleep that won't hold.
Each MGB+ formula targets a different layer of that conversation. Clear addresses the bloating-and-brain-fog cluster. Cool calms the upper-gut layer. Calm steadies the morning rhythm. The Trio works because the three layers reinforce each other.

Her story →
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.
Two capsules a day, total. Not two of each. The three formulas are designed to be mixed and matched — pull from whichever one matches what your gut is doing that day. With food is easier on the stomach. Maximum is three capsules a day.
Match the formula to the pattern. A bloating-and-brain-fog day might be 2 Clear. A heavy-meal evening might be 1 Cool. A queasy morning might be 1 Calm. A mixed day might be 1 of each. The Trio is built for flexibility, not a fixed schedule. Pay attention to what shifts after a few weeks and lean into the formula that's doing the most work for your pattern.
Generally yes. The Trio is built on well-studied molecules with strong safety profiles, and most customers stack it with other things they're already taking. If you take prescription medications, are pregnant or nursing, or have a chronic medical condition, check with your doctor before starting any new supplement.
After 8 to 12 weeks, you'll have a clearer sense of which formula is doing the most work for your specific pattern. You can stay on the full Trio, drop to two formulas, or shift to a single one. Your subscription is fully editable. Pause, swap, skip, or cancel anytime.
Some customers feel a shift within days, particularly with brain fog, sleep quality, and morning queasiness. The full pattern shift takes 8 to 12 weeks. That's why our guarantee runs 12 weeks. It's the realistic window for gut-brain conditions to remodel.
Every 90 days. One box of three bottles is a 90-day supply at the standard two-capsule-per-day dose, so the subscription ships in time to keep you covered without piling up surplus bottles. Single Trio is one box, one-time, no subscription. You can switch between subscription and one-time anytime, and you can pause, skip, swap, or cancel.
Yes. Every batch is tested by an independent laboratory for ingredient potency, heavy metals, and contaminants — not the same lab that makes the supplement. We use US cGMP facilities.
