I'll admit it—this is probably the most personal thing I've ever shared online.
But if my story helps even one person who's struggled with digestive issues the way I did for years, it'll be worth it.
The conversation that changed everything
I first heard about natto powder while chatting with a fellow entrepreneur based in Fukuoka, Japan.
During our conversation, she mentioned that she gives natto powder to her elementary school-aged daughter every day.
She laughed as she told me that whenever her daughter ate McDonald's, her farts would become incredibly stinky. But if she made sure her daughter had natto powder, the smell would disappear—and her daughter would consistently have what she called "banana-shaped poop," which is often considered a sign of healthy stool.
She told me she experienced the same thing herself.
At first, I laughed.
Then I thought...
Wait. Could this actually help me?
My lifelong struggle with constipation
I've dealt with constipation for as long as I can remember.
And here's the really embarrassing part.
My husband is one of the kindest, most patient people you'll ever meet. He almost never gets upset.
Except...
When I farted near him.
Because my farts smelled that bad.
As funny as it sounds now, it was honestly something I felt self-conscious about. On top of that, going to the bathroom was never easy. It wasn't unusual for me to spend 20–30 minutes sitting on the toilet, hoping something would happen.
If you've ever dealt with constipation, you know how frustrating—and exhausting—it can be.
I decided to try it myself
After hearing that entrepreneur's story, I couldn't stop thinking about natto powder.
I contacted the manufacturer in Japan, and they generously sent me a few samples to try.
Here's the ironic part:
I don't even like natto.
I know, I know...I'm Japanese and I don't like natto.
The smell.
The sticky texture.
I just could never get into it.
But natto powder felt completely different. Since it's freeze-dried and finely ground, it was much easier to add to foods or take in capsule form. It seemed like a simple way to enjoy the nutritional benefits of natto without forcing myself to eat something I didn't enjoy.
So I challenged myself to take it every day for 30 days.
I even documented the entire journey on my personal Instagram Stories.
The results surprised me
Honestly...
I wasn't expecting much.
But within days, I noticed changes.
The biggest one?
I started having bowel movements almost every day.
Even more surprising was the texture.
This might be TMI, but in my 38 years of life, I can count on one hand the number of times I'd had those effortless, smooth, "banana-shaped" bowel movements that doctors often describe as ideal.
Suddenly...
They became my new normal.
No straining.
No sitting on the toilet for half an hour.
Just...normal.
And then something else happened.
My stinky farts disappeared.
Not only did they stop smelling, but I also found myself passing gas much less often.
For the first time in years, I could confidently hang out with my husband without worrying about clearing the room.
That alone made the experiment worth it.
Why I decided to carry natto powder at Yuzu Marché
After my 30-day challenge, I knew I wanted to share this product with other people who might be dealing with the same struggles.
That's why I decided to partner with the manufacturer and make this authentic Japanese natto powder available through Yuzu Marché.
Everyone's body is different, and my experience is just that—my personal experience.
But if you've struggled with constipation, bloating, or poor gut health, I think this is one of those products that's genuinely worth trying.
Why natto is considered one of Japan's healthiest foods
Natto has been eaten in Japan for over 1,000 years and is widely known as one of the country's traditional functional foods. It's made by fermenting soybeans with Bacillus subtilis var. natto, a beneficial bacterium that naturally produces compounds during fermentation.
Research on natto suggests it may support overall wellness because it contains:
-
Beneficial probiotics that help support a healthy gut microbiome.
-
Vitamin K2, an important nutrient that supports bone health and helps the body properly utilize calcium.
-
Nattokinase, a naturally occurring enzyme produced during fermentation that has been studied for cardiovascular health.
-
Plant-based protein and fiber, which help support digestive health and provide lasting nutrition.
Why I chose freeze-dried natto powder instead of fresh natto
One question I get all the time is:
"Why not just eat regular natto?"
If you already love fresh natto, that's fantastic.
But freeze-dried natto powder has some practical advantages:
-
It's easy to sprinkle into smoothies, yogurt, soup, oatmeal, rice, or pasta.
-
There's no slimy texture.
-
It has a much milder aroma than fresh natto.
-
It doesn't require refrigeration.
-
Freeze-drying helps preserve natto's nutrients while making it much easier to incorporate into everyday meals.
Another unique feature is that the beneficial Bacillus subtilis bacteria are present in a durable spore form. These spores are naturally resistant to stomach acid, increasing the likelihood that they reach the intestines alive compared with non-spore probiotics.
If my story sounds familiar...
If you've spent years dealing with constipation...
If you've been embarrassed by bloating or smelly gas...
Or if you're simply looking for an easy way to support your gut health...
I hope you'll consider giving natto powder a try.
It completely changed my daily routine, and I honestly wish I'd discovered it years earlier.
Sometimes the smallest habit—a single spoonful a day—can make the biggest difference.
