Bad Breath | Analysis

"The methods used to treat bad breath in Canada are a complete nightmare." A renowned Japanese gut health expert gave a shocking interview to a Canadian publication.

Hiroshi Takeda is senior director of the world-renowned Tokyo Center for Microbiota and Digestive Health.

There is only one true cause of persistent bad breath — but it is completely ignored by Canadian doctors.

Dr. Hiroshi Takeda: “In Canada, bad breath is still treated with outdated, ineffective methods that only cover up the problem and require constant use. In Japan, we treat bad breath as easily as a common cold.”

Dr. Hiroshi Takeda traveled to Canada last year to learn from his Canadian colleagues.
What he witnessed, he says, “is simply beyond explanation.”
In his view, the Western approach to treating halitosis stopped evolving sometime in the mid-20th century.

After giving several interviews in Japan, Dr. Takeda agreed to speak with our Canadian publication.
Why do you say the Canadian methods don’t work?
And why are so many people here stuck with chronic bad breath with no real solution?

While speaking with Japanese journalists, Dr. Takeda said what he saw in Canada left him shocked.
Can you comment on that?

First of all, I want to say that I truly admire Canada — its people, its culture, and its energy.
But as a doctor, the state of medicine here — especially regarding digestive health and halitosis — is deeply concerning.
Canadian medicine is, at best, 20 or 30 years behind.
When it comes to bad breath, the science of halitology barely exists in Canada.

Just look at what most Canadian doctors and dentists still recommend:
alcohol-based mouthwashes, mint sprays, sugar-free gum, breath mints, and aggressive brushing with strong toothpastes.

None of these methods treat the actual cause.
They only mask the symptoms — the bad taste, the dry mouth, the odor.
But inside the body, the problem continues.
You rinse or spray, and yes, your breath feels better for a moment —
but within hours, the bad smell comes back — often worse than before.

Bad breath is a warning sign.
It’s your body telling you something is wrong — usually in your gut, stomach, or oral microbiome.
By simply silencing that signal, you allow the real issue to get worse.
The imbalance grows. Sulfur compounds build up. Beneficial bacteria are destroyed.

In Japan, the practice of masking bad breath with chemicals has been abandoned for over 20 years.
Today, these products are viewed not as treatments, but as outdated relics from a time when the biological causes of halitosis were still poorly understood.

Clinical research made it clear:
While these formulas can suppress odor temporarily, they do so at a cost —
by disrupting the microbiota, drying out the mouth, and worsening the very imbalance that causes bad breath.

Instead of healing, they create a cycle of dependence.
The fresh taste fades, the real problem deepens —
and the consumer keeps coming back, again and again, chasing short-term relief.

And that, in my opinion, is unacceptable.

So how is bad breath treated in Japan?

All Japanese doctors — from university professors to general practitioners and holistic therapists — have long understood that you cannot treat the symptoms of bad breath. You have to eliminate the cause.
That’s the only way to achieve a real, fast, and safe cure.

And what is the main cause of chronic bad breath?

A deep imbalance in the microbiome — both in the gut and the mouth.
This imbalance allows harmful bacteria to multiply and produce volatile sulfur compounds, such as putrescine and cadaverine.
These toxic molecules are responsible for the foul odor — and no amount of brushing or rinsing can stop them.

They’re just the surface sign of a deeper problem:
• Sluggish digestion
• Constipation
• Gut dysbiosis
• Acid reflux
• Dry mouth
• Chronic stress

All of these weaken the beneficial bacteria and create the perfect environment for odor-causing microbes to thrive.

In Japan, we don’t treat bad breath with gum or mouthwash. We treat it with science.

The first step is to restore the healthy flora in the gut and mouth — eliminating harmful bacteria and repairing the digestive system.

Once the microbiome is restored, the body stops producing those odor compounds, and fresh breath returns naturally.

The human body has a remarkable ability to regenerate — even when it comes to something as stubborn as bad breath.
The gut and oral microbiome can fully recover, as long as the internal imbalance is corrected and the right biological support is provided.

In the late 1990s, a team of Japanese researchers, in collaboration with Swiss scientists, launched a groundbreaking study:
to identify natural compounds capable of restoring microbiome balance and neutralizing the production of odor-causing compounds at the source.

After years of research, they reached a surprising conclusion:
The real cause of persistent bad breath wasn’t in the mouth — it was part of a wider dysfunction across the digestive and microbial systems.
And the secret to reversing it was reactivating the body’s natural ability to regulate its internal environment through microbial modulation.

From there, they tested hundreds of fermented ingredients, microbial strains, and plant-based prebiotic fibers, eventually identifying a group of microorganisms and compounds that could:

rapidly reduce sulfur compound levels
restore natural pH in the mouth and gut
stimulate the growth of beneficial bacteria
and stop bad breath at its origin

What once seemed impossible — truly fresh breath without mouthwash, sprays, or mints — was now backed by hard science and clinical results.

This breakthrough marked the beginning of a new era in treating halitosis — no more masking, no more shame. Just a real solution at the root cause.

When I looked at medical statistics from Canada, I was shocked.
Do you know one of the leading causes of social anxiety, relationship breakdowns, and professional insecurity in Canada?
A simple, solvable problem — but one that continues to be misunderstood and mistreated: bad breath.

In Japan, this condition is addressed at the root.
Here, chronic halitosis is not viewed as a hygiene failure, but rather as a biological signal — a sign that something deeper is out of balance within the body, particularly within the microbial systems of the gut and mouth.

We call it Halitogenic Dysbiosis: a disruption in the microbiome that triggers the excessive production of volatile sulfur compounds — the molecules responsible for persistent odor.

This dysbiosis can manifest in different ways:

• Oral halitosis — linked to tongue coating, gingival inflammation, and oral biofilm imbalance
• Gastric halitosis — resulting from acid reflux or delayed digestion
• Intestinal halitosis — caused by microbial imbalance, constipation, or fermentation
• Emotional halitosis — a consequence of chronic stress, cortisol spikes, and dry mouth

Each of these forms stems from the same underlying mechanism: a dysregulated microbial environment.
And that means they can all be addressed through a single, comprehensive therapeutic strategy.

So how is this treated in Japan?

Today, clinicians and researchers rely on advanced formulations specifically engineered to:

✅ Restore microbial harmony
✅ Reduce sulfur compound production
✅ Support systemic digestive function

Among the most effective is a patented microbiome restoration complex known as Hali10.

Hali10 is made with a special mix of nine probiotic strains, including:

Lactobacillus acidophilus, L. casei, L. salivarius, L. plantarum, L. rhamnosus, L. brevis, Bifidobacterium bifidum, Streptococcus thermophilus, and B. lactis/longum, along with the prebiotic FOS (fructooligosaccharide).

This precision-targeted formula operates on five biological fronts:

• Promotes a healthy, stable microbiome in the gut and mouth
• Supports mucosal barrier integrity and intestinal homeostasis
• Encourages the body’s natural antimicrobial defense mechanisms
• Inhibits colonization by odor-producing pathogens
• Enhances immune modulation and nutrient assimilation

Many clinical studies and reviews have looked at how these strains help with bad breath.

One review, published in the Journal of Clinical Periodontology, showed that probiotics, especially certain Lactobacillus types, can be effective in fighting bad breath because they help lower the number of bad bacteria in the mouth.

Other studies have found that strains like Lactobacillus salivarius and Streptococcus salivarius K12 can help improve bad breath in a short time (up to 4 weeks).

Research has also shown that using probiotics can make your mouth healthier and lower the amount of volatile sulfur compounds (VSCs), which are a major cause of bad breath.

These scientific findings support how well the ingredients in Hali10 work to fight bad breath, offering a research-based way to bring balance back to your mouth and get rid of bad breath for good.

With Hali10, odor compounds are addressed at the source — and breath freshness becomes not just possible, but sustainable.
No mouthwash. No gum. No masking. Just a real, biological solution.

The documented results of the treatment speak for themselves:

Week 1: bad taste in the mouth fades, fresh breath in the morning returns
Week 2: noticeable digestive improvements, less bloating and gas
Week 3: over 87% of users report total breath freshness and improved daily energy
Week 4: full microbiome balance restored, fresh breath maintained naturally, and renewed confidence in face-to-face conversations

What advice would you give to Canadians struggling with bad breath?

Ordinary people — especially those over 40 — suffer the most.
Not because they don’t care, but because no one ever told them the real cause of their problem.
It’s not their fault.
It’s the system that keeps pushing sprays and mouthwashes instead of teaching true gut health.

But fortunately, there is a solution.

An official website has been created where anyone in Canada can order Hali10 at a special discount — safely and directly from the manufacturer.

We’ve been distributing Hali10 in Canada for just a few months, and thousands of Canadians have already taken advantage of the opportunity.

Only until the promotional supply runs out.
And it’s going fast. Demand is rising every day as people spread the word, recommend it to friends, and even order extra bottles for loved ones.
No one wants to rely on mouthwash and sprays forever.

It’s really tough when a friend or relative has bad breath. I went through that with someone close. It’s so awkward to tell them. I bought 3 bottles and left them at her doorstep with an anonymous note… I’m sure she felt a little hurt at first, but it worked. Now I can talk to her face to face without any bad smell.
