What Is Natto?

Natto is a traditional Japanese comfort food made from whole soybeans fermented with Bacillus subtilis. For over a thousand years, a staple food in Japan, often enjoyed with rice for breakfast, a healthy snack or simple side dish.

Natto is even served in school meals for kids in Japan.

Don’t believe the haters!

You'll find our natto has a pleasantly earthy taste & mild aroma.

Why is NYrture Natto Special?

Gut-Friendly Probiotic

Fermented with Bacillus subtilis, a spore probiotic that supports a healthy gut microbiome and helps beneficial bacteria thrive.  You’re unlikely to find B. subtilis in other fermented foods or supplements, which is what makes natto so special. B. subtilis also makes natto an alkaline fermented food. 

Best Source of Vitamin K2

Natto is the richest known food source of vitamin K2 (MK-7), which helps guide calcium into bones...

...and out of your arteries.

Natural Source of Nattokinase

Natto contains nattokinase, a blood thinning enzyme, well studied for supporting healthy circulation and cardiovascular wellness.

Plant-Based Protein & Nutrients

A great source of unprocessed complete plant protein, fiber, iron, magnesium, calcium, zinc, and other essential nutrients.

Clean, Simple Ingredients

Made with just two whole ingredients: 

1) non-GMO/organic soybeans

2) live probiotic cultures. 

No added salt, sugar, or preservatives.

Fresh & In Glass

Crafted fresh in glass, never frozen, to best preserve freshness & flavor.  No single use plastic waste or micro-plastics in food.

Great for vegan, keto, paleo, gluten-free diets. It’s UKosher too!

Salt-free, the natto tastes much better mixed with a little soy sauce or a favorite savory dressing. A dash of hot sauce, mustard or spice adds some zing.

For traditionalists, sliced scallions & a raw egg yolk are classic but optional add-ons.

I have been buying NATTO from this company for about five years. They have the best natto I’ve seen anywhere. Fast and reliable shipping.

★★★★★

I said I would never eat natto, until I tasted NY Natto. …Even in the summer heat, the package arrives with mostly frozen freezer packs, so the natto containers still feel cold.

★★★★★

I introduced natto to my diet two months ago to take advantage of the benefits it provides to reducing cholesterol without medication (it's the BEST natural source of vitamin K2, a key player in cardiovascular health). My previous reading 4 months ago was 289 - after eating natto for a month in my lunch, my reading was 228! While I can't attribute the entire decline to just natto, I am convinced it was a big factor.

★★★★★

I said I would never eat natto, until I tasted NY Natto. …Even in taI have been eating natto for over 40 years and this is the best I have ever had. If you like natto you must try this! If you have never had natto, order some, make some rice and noodles and have a natto tasting party. Watch a few videos on Youtube to learn how it is traditionally eaten and also check out the NYrture website for nutritional info. I sometimes eat natto on toast and it is way better than avocado (although you can put natto on top of the avocado). HIGHLY recommended!he summer heat, the package arrives with mostly frozen freezer packs, so the natto containers still feel cold.

Natto usually comes in a single serving styrofoam which usually dries out the beans as it's not airtight. It's also usually prefrozen to maintain freshness and often the beans lose texture.When I first saw this, I was definitely skeptical but i could not be happier with the purchase. It's got great texture, flavor, and it comes in a resealable jar so the beans never dry out. I just add some soy sauce and japanese mustard for flavor and goes great with rice, obviously.

I lived in Japan for 20 years and I love natto. Having eaten natto from Hokkaido to Kyushu, Ann's natto is as good as the very best handmade natto I've ever tasted in remote locations and better than all the natto in supermarkets and department stores and I've tried most of them over many years. It's hard to believe that such delicious authentic natto is available here in the United States. Kudos to Ann for creating such a great product. Trust me, New York Natto is truly amazing!!!
