+ 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.
Both patterns run on one line.
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.
Built by a doctor. Reviewed by an independent clinical board.
The patterns I kept seeing rarely travel alone. The bloat comes with the burn, the fog with the queasy morning. Pairing two formulas is how you meet a gut that acts up in more than one way.

Same two formulas, one lower price and one subscription to manage. The Duo saves $49 one-time, or $62 every 60 days on subscription, versus buying MGB+ Clear and MGB+ Calm separately.
Both bottles, plus the Welcome Kit free with your first order: your printed Protocol Cards and a couple of BellyMD extras.
Two capsules a day, pulled from whichever of the two the day calls for. The same simple rhythm as taking one. On heavier days, some people take one from each. Both bottles are full-size, 60 capsules each.
Let the day decide. MGB+ Clear is built for bloating, brain fog & the afternoon crash; MGB+ Calm for queasy mornings & a nervous stomach. Most people find they reach for one more than the other, and that's fine.
Only the subscription renews, 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.
