Subtle Flavor, Full Nutrition

For more than 1000 years, Japanese natto has been considered one of the safest probiotics food. Made by fermenting soybeans with the Bacillus subtilis bacteria, it’s also naturally rich in vitamin K2, nattokinase, amino acids, and enzymes for longevity and overall wellbeing. 

More Nutritional Benefits than Raw Natto

The Bacillus subtilis (probiotics) of our natto powder are in spore form, making them resistant to heat (100°C), UV radiation, and acidity. Produced through cutting-edge technology, each serving of Sonomono natto powder contains more nutrients and probiotics than raw natto. 

Well-Preserved Natto Taste and Nutrition

Good natto is distinguished by its firmness, color, smell, umami, and nutrients bioavailability. Even in powdered form, our natto freeze dried food delivers the same flavors and nutrition as raw natto but with a less pungent aroma. 

Comes in 2 Flavors

Classic - Raw and pure natto flavor.

Mild - Same nutrition but with a mild aroma and reduced smell and viscosity. Directions
