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.
