More Than Just a Breath Freshening Supplement
Rather than simply masking odors with fragrance, Koukatsu Care focuses on the oral environment associated with unpleasant breath.
For those concerned about a sticky feeling in the mouth, discomfort after waking, or the impression of their breath.
Add a new oral care routine after brushing every day.
When You Start Noticing Your Breath, It May Be Time to Review Your Oral Care
Bad breath is not something that can be solved simply by masking it with fragrance.
Have you noticed any of these recent changes in your mouth?
• You find yourself wanting a toothpick after meals
• Food has started getting stuck between your teeth more often
• Your teeth appear longer than they used to when you look in the mirror
• You have started noticing your gums or the spaces between your teeth when you smile
• You are concerned about stickiness or discomfort in your mouth when you wake up
• You are concerned about the impression of your breath when speaking closely with someone
Even when your skin and hair are well cared for, noticeable gums or spaces between the teeth can sometimes make the mouth appear older.
When you start noticing your breath, it may be a good opportunity to review your overall oral care routine.
Rather than temporarily masking odors with fragrance, it is important to make daily brushing and regular dental care the foundation of your routine, while also paying attention to your oral environment.
Look Beyond the Odor
Bad breath can be influenced by various aspects of the oral environment, including tongue coating, gum condition, tooth spacing, and changes in saliva.
Simply masking odors temporarily with fragrance or mint does not address the underlying oral environment associated with bad breath.
If you begin to notice stickiness in your mouth, discomfort upon waking, or changes in the impression of your breath, it may be time to pay closer attention to changes in your oral condition.
Along with daily brushing and regular dental care, consider adopting a routine that helps you stay mindful of your oral environment every day.

A NEW ORAL CARE HABIT TO START IN YOUR 40s
MORE THAN FRESH BREATH.
HEALTH AND YOUTHFULNESS BEGIN WITH YOUR MOUTH.
As we enter our 40s, many people begin to notice changes in their oral health.
Bad breath that was never a concern before.
Sticky or unpleasant feelings in the mouth upon waking.
Bleeding gums or changes in gum condition.
These changes may not be caused by age alone.
They may also be linked to an imbalance between harmful and beneficial bacteria in the mouth.
Koukatsu Care was not created simply to mask bad breath.
It was developed to support a healthier oral environment by targeting harmful bacteria while helping maintain beneficial bacteria.
Koukatsu Care is a Japanese powdered oral care product designed for use after brushing.
Mints, gum and mouth sprays may temporarily cover unpleasant breath. Koukatsu Care takes a different approach.
It focuses on the oral environment itself, with consideration for the balance between unwanted oral bacteria and beneficial bacteria naturally present in the mouth.
BEFORE YOU GET CLOSER,
CARE FOR MORE THAN JUST YOUR BREATH.
Confidence is not only about smelling minty.
It is about feeling clean, comfortable and confident about your whole mouth — especially before a kiss, an important conversation or a close moment with someone special.
A DIFFERENT APPROACH TO ORAL CARE
Most mouthwashes and antibacterial products simply kill bacteria.
While they may provide temporary freshness, they can also reduce beneficial bacteria that help maintain a healthy oral environment.
Koukatsu Care takes a different approach.
Instead of simply killing bacteria, it focuses on harmful bacteria while helping maintain the balance of beneficial bacteria.
With continued daily use, it supports a healthier oral environment from within.
• Targets harmful bacteria
• Helps maintain beneficial bacteria
• Supports a balanced oral microbiome
• Fine powder that spreads easily throughout the mouth
• Easy to use before bedtime
• Made in Japan
KEY INGREDIENTS
IgG (Immunoglobulin G) – The Core Ingredient
The key ingredient in Koukatsu Care.
IgG binds to harmful bacteria and helps support a healthier oral environment while respecting beneficial bacteria.
Unlike conventional antibacterial products, it is designed to help maintain the natural balance of the oral microbiome.
Lactoferrin
A naturally occurring protein found in milk.
Lactoferrin has been studied for its role in supporting oral health, including research related to bacterial biofilms and maintaining a healthy oral environment.
Propolis
A natural substance produced by honeybees.
Traditionally used for centuries, propolis helps maintain a clean and healthy mouth as part of your daily oral care routine.
Xylitol
Provides a mild, refreshing sweetness, making Koukatsu Care easy to use every day.
YOUR MOUTH MAY BE THE FOUNDATION OF YOUR HEALTH
Recent research has highlighted the close relationship between oral health and overall wellness.
Studies have reported associations between periodontal bacteria and conditions such as cardiovascular disease, diabetes and colorectal cancer.
Researchers have also detected periodontal bacteria in the brains of some patients with Alzheimer's disease and dementia, leading to growing interest in the connection between oral health and healthy ageing.
Keeping your mouth healthy is not only about fresh breath.
It is about supporting your overall health, your confidence and your quality of life for years to come.
Healthy ageing begins with a healthy mouth.
A SMALL DAILY HABIT.
