+ 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.

All three patterns run on one line.

The gut and brain connected by nerves, surrounded by botanical ingredients

Your gut and brain run on a single nerve line, the gut-brain axis, and that line needs fuel. Every MGB+ formula feeds it a well-absorbed form of B1, with magnesium alongside. Then each formula adds targeted helpers for its own pattern.

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 patternWhichever formula the day called for, note how the day ran: mornings, meals, afternoons. 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 good days than off ones.
Weeks 8 to 12Decision pointBetter? Keep going. Not better? Your first order is free.

I am an ER doctor. The patterns I kept seeing rarely travel alone: the bloat comes with the burn, the fog with the queasy morning. The Trio is the whole toolkit.

“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.”

Start with the Trio

The things people ask first.

It is a structured way to use the MGB+ Trio consistently for 12 weeks, with the complete Trio, a printed evidence booklet, and guided check-ins every two weeks. Three bottles is 90 days of capsules, so you finish the 12 weeks with a few days spare.

The Trio includes MGB+ Clear, MGB+ Cool, MGB+ Calm, the Welcome Kit with your first order, a printed 34-page evidence booklet, and the 12-week protocol email series.

The printed, bound evidence booklet is included with qualifying Trio orders and ships with your order.

After purchase, you’ll receive guidance every two weeks for 12 weeks. Each email focuses on a specific part of the protocol, including consistency, the three-formula system, what to notice, and how to evaluate the full 12 weeks.

Your first order is covered by BellyMD's 12-week money-back guarantee, up to three bottles.

Two capsules a day total, not two of each. Pull from whichever formula matches the day. One box of three bottles is a 90-day supply.

Many people lean on one most days. Keep all three on hand, or switch to a single formula anytime.

Only the subscription renews, every 90 days, and the page always tells you what 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.

These are gentle daily supplements, but they are 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 printed on each formula's page. Note: Cool contains mastic gum, a tree resin. Do not take Cool if you have a tree nut allergy.

Try it for 12 weeks. Not helping? Your first order refunded, up to three bottles. Keep them.
