What's in the pair
Two formulas, one subscription.
Heartburn & post-meal heavinessMGB+ CoolFull label →
Queasy mornings & a nervous stomachMGB+ CalmFull label →
Two full-size bottles, 60 capsules each. Every dose printed on each formula's label, no proprietary blends.
Why these two
One gut. Two patterns that travel together.
A stomach that burns after dinner and turns over before breakfast is one sensitive gut, not two separate problems. Cool works the post-meal heat and the settling response; Calm supports the queasy morning and the nerves that pace it. Paired, they steady the whole day around the table.

The one quiet cause
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
Why you can trust this
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.

The things people ask first.
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+ Cool and MGB+ Calm separately.
Both bottles, plus the Welcome Kit free in your first box: 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+ Cool is built for heartburn & post-meal heaviness; 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.
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 entire first order, both bottles included. Keep the bottles, nothing to ship back. One guarantee per customer, because we mean it.
