1. The smell is coming from your gut. That is why brushing never stops it.

Bacteria in your gut ferment undigested food into hydrogen sulfide gas. That gas passes through your intestinal wall, enters your blood, travels to your lungs, and comes out with every breath you take. No toothbrush reaches that.

Research shows 84% of people with gut bacterial overgrowth have breath odor that starts below the neck. Your dentist has no tool for that. Breevo uses Berberine HCl, Bromelain, and Papain to stop the fermentation before it starts.

2. Your liver is supposed to filter the smell before it reaches your breath. Here is what happens when it cannot.

Your liver catches sulfur compounds from your gut and clears them before they reach your lungs. But stress, antibiotics, and poor diet slow it down. When it falls behind, those compounds slip into your blood and come out with every breath.

Doctors have a name for this. They call it fetor hepaticus. It has been documented since the 1980s. Mouthwash cannot touch it. Breevo includes Artichoke Leaf Extract and Chlorophyllin specifically to support this pathway. No other breath product does.

3. The probiotic you tried did not fail. The capsule did.

Standard capsules dissolve in your stomach in under 30 minutes. Your stomach acid sits at a pH of 1.5 — close to battery acid. At that level, 95 to 99% of the live bacteria inside a standard capsule are dead before they ever reach your gut. You were not taking the wrong probiotic. You were swallowing dead bacteria.

Breevo uses enteric-coated capsules that stay sealed through stomach acid and only open in your small intestine. Clinical data shows this delivers 20 to 40 times more live cells intact.

4. Most "breath probiotics" were never tested for bad breath.

Most probiotic products use gut strains that help with digestion. That is it. They were never studied for breath. You took them for months. Your gut felt better. Your breath stayed the same. That is not a coincidence.

Breevo uses S. salivarius K12, the only probiotic strain with clinical trials showing a direct reduction in the compounds that cause bad breath. Studies show it can reduce sulfur compounds in the mouth by up to 85%. That is not a gut strain. That is a breath strain. There is a difference.

"Three dentists. Two ENTs. A gastroenterologist who said it was stress. The gut-liver connection was the first thing that made sense of fifteen years of being told nothing was wrong."

5. A doctor who got tired of telling patients he had nothing for them.

For years, patients sat in my exam room and mentioned it at the end of their visit. "My breath. I've tried everything. My dentist says my mouth is perfect."

I heard it over and over. Same story. Same dead ends.

The problem was not in their mouths. It was in three systems working against them at the same time. Dentists check mouths. GI doctors check guts. Nobody was connecting all three. So I left my practice and built Breevo to fix all three at once.

*"I've seen five doctors in three years. Every single one looked at a different part of my body and sent me home with nothing. Dr. Holt was the first person who ever explained how all of it connects. That alone was worth it."

— Sandra K., 44, Verified Buyer*

6. Most people start noticing by week 3. Here is what that looks like.

Breevo is not a mint. It does not work in fifteen minutes and fade in twenty. It fixes root causes. That takes a few weeks to feel.

Week 1–2

Subtle shifts. Morning breath a little less intense. The metallic taste starting to fade.

Week 3–4

You wake up and the first thing you notice is nothing. No coating on the tongue. You leave for work without the hand check. You sit through a meeting without angling away. The gum stays in the bag.

Month 2–3

You stop thinking about it. One day you realize you have not thought about it in a week.

"Week one I thought it was placebo. Week three my wife leaned in during a movie and did not pull back. That was the moment I knew something had actually changed."
