The coffee isn't the problem. The reflex is.
A cup lands in the stomach, and within minutes the colon gets the order to move. In a reactive gut that same wiring over-reads everything, and the burn high in the belly is part of the pattern. An emergency physician on the signal, the lining, and the formula he built for exactly this gut. Ten-second check below.

Coffee that sends you to the bathroom is the gastrocolic reflex turned up. When it comes with a burn high in the belly, you may be looking at one gut-brain pattern, not two problems. Here is the reflex, the study that timed it, and the formula I built in two halves: one for the wiring, one for the lining.
Step 1. Tap what sounds like you.
Step 2. Tap what is true most weeks.
The cup lands in the stomach. The colon gets the message.
That is the gastrocolic reflex: the stomach stretches, the nerves report it, and the colon starts moving to make room. Everyone has it. In a reactive gut the volume is turned up, so a cup of coffee reads like a full meal, and the same over-reading nerves light up the stomach itself as a burn high in the belly. Tap what you have tried.
Four of those act on the symptom. One supports the wiring.
Four minutes from the first sip, the colon was moving.
Researchers put pressure sensors in the colon of healthy volunteers and gave them coffee. The colon began contracting within four minutes of the cup, before any caffeine could have been absorbed into the blood. That speed is the fingerprint of a nerve reflex, not a drug effect. Caffeinated coffee moved the colon about 60 percent more than water did, about as much as a thousand-calorie meal, and decaf moved it too.
A reflex everyone has only becomes a problem when the wiring over-reads it. That is what a disorder of gut-brain interaction is: the parts pass inspection, and the signal between gut and brain is set wrong. The largest survey ever done, 73,000 adults in 26 countries, found that four in ten meet criteria for at least one. Bowels that over-react to a meal and a burn high in the belly commonly travel together, because they share the wiring.
So I built Cool in two halves.
Two things wear down in this pattern: the wiring that reads the stomach, and the lining that meets years of morning coffee. An antacid touches neither. Cool is built for both. Seven actives, two capsules a day, with a meal.
The gut's nerve and muscle cells use vitamin B1 for energy, and compounds in coffee can inactivate ordinary B1. Allithiamine, a fat-soluble B1, and magnesium glycinate support normal nerve and muscle function. Ginger supports comfortable digestion after a meal.*
Mastic gum, zinc carnosine, DGL licorice and aloe inner gel support a healthy stomach lining.*

"I noticed such a significant change and calmness in the gut, I recommended it to family."
For adults whose bowels over-react to coffee and meals and who carry a burn high in the belly, worse with stress. Not for pregnancy, nursing, or under 18. Ask your clinician first if you take a blood thinner or live with kidney disease.
Cool is not an antacid and does not replace a prescription. Blood in the stool, black stools, vomiting blood, unexplained weight loss, fever, or symptoms that began after 50 is a doctor visit, not an order.
Do I have to give up coffee?
No. The reflex is normal and the coffee is not the disease. The pattern is the wiring over-reading it. Keep the cup; Cool goes alongside it, with a meal.
Would decaf fix it?
In the study, decaf moved the colon too, about a quarter less than the caffeinated cup. The signal is a nerve reflex to the drink landing, not a caffeine effect, which is why switching rarely solves it.
Can I take it with my acid reducer?
Yes, for most people. Cool contains no acid blocker and does not replace one. Keep taking what your clinician prescribed and bring the label to your next visit.
Why B1 for a gut problem?
The gut's nerve and muscle cells use B1 to make energy, and the wiring is what is over-reading. Compounds in coffee, and several common prescriptions, metformin and some antidepressants among them, interfere with ordinary thiamine. That is one reason Cool uses the fat-soluble form.
Is the licorice safe for blood pressure?
Cool uses DGL, licorice with the glycyrrhizin removed. Glycyrrhizin is the compound that raises blood pressure.
How does the guarantee work?
Twelve weeks from delivery. If Cool is not helping, email support@belly-md.com and your first order is refunded, up to three bottles. You keep the bottles. One refund per household.

The 1998 and 1990 studies cited measured how coffee affects colonic motor activity in healthy volunteers, and the 2021 survey measured how common gut-brain disorders are; none tested MGB+ Cool or any supplement. *These statements have not been evaluated by the Food and Drug Administration.
