Step 1: Find Your Type. Step 2: Get Your Protocol.
For some people, chronic bad breath traces back to gut-produced sulfur compounds that can travel through the bloodstream and be released through the lungs - which brushing alone can't reach. Take the free 4-question test to see which gut breath pattern best matches what you're experiencing, then get the 30-day protocol built around it for $47, backed by a 90-day money-back guarantee.
Educational self-test, not a medical diagnosis. Written by Jordan, based on research into gut-related causes of chronic bad breath - see the full explanation and sources on the protocol page.

"I spent hundreds on mouthwashes and probiotics over the years. What was different here is that it focused on the gut - not just covering up the smell. My morning breath improved noticeably within a few weeks and I felt more confident in conversations."

"No complicated medical jargon. Just clear instructions and actionable steps. Even when I wasn't perfect with the protocol, I still noticed real improvements in my digestion and breath."

"I sat through an entire dinner on a first date calculating whether they could smell what I was smelling. This was the first thing that gave me an actual plan instead of just more products."

Why generic solutions never fully solved it
There are 5 distinct gut breath patterns and each one has a different source: food timing, overnight buildup, dryness, anxiety, or multiple triggers at once. Mouthwash, tongue scrapers, and extra brushing don't address the source. The source is upstream - in your gut. The free self-test identifies your pattern. The protocol is built around it.
Learn more about the protocol →The smell comes back within 20 minutes of brushing - because it's coming from your lungs, not your teeth.
You've tried every rinse and mint but nothing holds more than an hour. That's what happens when you're targeting the exit and not the source.
Your worst days follow specific foods, coffee, an empty stomach, or stress - not poor hygiene. That's your pattern.
Your dentist says everything looks fine. Because it is fine - in your mouth. The cycle starts in your gut.
The cycle behind it
This isn't a hygiene problem. It's a production cycle that mouth-focused solutions can't reach.
Step 01
Certain foods, fasting windows, or digestive patterns trigger sulfur gas production deep in the gut.
Step 02
Gases absorb into the bloodstream and are carried to the lungs, bypassing the mouth entirely.
Step 03
The smell emerges on exhale. It comes from the lungs, which is why brushing and tongue scraping can't stop it.
Step 04
Rinse, brush, mint. Brief relief. Gut production resumes and the odor returns, because nothing touched the source.
The only way to break the cycle is to address the source, not the exhaust.
That's what the Gut Breath Type self-test identifies. That's what the protocol addresses.
5 gut breath types. Each one has its own reset protocol.
Most people with this problem have been getting generic advice for a specific condition. Once you know your type, the 30-day protocol gives you the exact reset designed for it.
These are working categories we use to personalize your protocol - not clinical diagnoses.
Morning-Heavy Pattern
The sulfur builds overnight and nothing clears it before you start your day. The protocol's morning reset sequence is designed to interrupt this pattern at the source.

Food-Triggered Pattern
Coffee, proteins, and fermentable carbs convert to sulfur gas during digestion. The Food Trigger Map inside the protocol helps identify and remove your exact inputs.

Dry-Mouth Pattern
Saliva neutralizes sulfur as it forms. When flow is low, the compounds accumulate instead of clearing. The protocol supports the natural clearing cycle.

Social-Anxiety Pattern
Stress reduces saliva and increases mouth breathing, both of which concentrate sulfur. The Emergency Confidence Plan inside the protocol is built to address this cycle.

Self-test preview
These are the kinds of questions the self-test works through. Each answer helps identify which gut breath pattern is most active for you.
When do you usually notice the rotten egg or sulfur-like smell during the day?
Which foods or drinks have you noticed make the odor noticeably worse?
How long does rinsing or brushing typically hold the smell back?
Do you rely on gum, mints, or sprays before close conversations, just in case?
The test is step 1. The protocol is step 2.
This is not a quiz that gives you a label and sends you away. Your type connects directly to a 30-day structured reset and a same-day confidence plan - both built specifically around your pattern.
