One shared base

Every formula starts with magnesium glycinate, a gentle and well-absorbed form of magnesium, plus a fat-soluble form of vitamin B1. Both support the pathways your gut and brain use to talk to each other.

Open labels

Every ingredient and every dose is printed on the label. No proprietary blends, nothing hidden, and each formula page links the published studies behind each ingredient.

Reviewed by clinicians

An independent advisory board of four clinicians reviewed the framework and the evidence behind every formula. They are named, with credentials, further down this page.

The three formulas

Which of these sounds like you?

All three share the same base, magnesium glycinate plus a well-absorbed form of vitamin B1. Pick the one that matches what you notice most.

Start with one. Add a second later only if a different pattern keeps showing up.

The founder

Built by a physician who kept seeing the same missing pattern.

Normal labs. Normal scans. Real symptoms. Bloating, nausea, fog, fatigue, burning, and mornings that start wrong. I built MGB+ so people could match what they feel to a formula made for it.

I'm Rick Pescatore, D.O., an emergency physician, former state chief physician, and editor-in-chief of Emergency Medicine News, the publication ER doctors have read for decades. I built BellyMD to make these patterns easier to name, track, and support.
