Natto powder provides the same health benefits as regular natto—including enhanced digestion, immune support, and improved bone and heart health—thanks to its rich content of probiotics, vitamin K2, and the enzyme nattokinase. However, a key advantage of natto powder is that its probiotic bacteria are in spore form, making them highly resilient. This allows the beneficial bacteria to survive the digestive process intact, reach the intestines unharmed, and thrive to promote the growth of other beneficial gut bacteria, further enhancing gut health.

Sonomono Natto Powder is a premium, 100% pure natto food product—no fillers, no additives, just the full potency of natto in every scoop. Unlike other products, we never mix it with soybean powder or other ingredients, so you’re getting the complete spectrum of natto’s natural goodness. This includes all essential amino acids, minerals, vitamin K2, and the unique enzyme nattokinase, renowned for its potential heart and blood circulation benefits. Plus, thanks to our careful processing, our natto powder boasts a higher concentration of probiotics per gram to support your digestion and immune health.

Our Natto Powder comes in two varieties—Classic (navy blue label) and Mild (light blue label)—so you can choose the perfect match for your taste. Both versions provide the same nutrient levels and amount of beneficial natto bacteria. The only difference is in aroma and texture: the Mild version has less smell and stickiness once hydrated, making it ideal for those who prefer a subtler natto experience or are new to natto. If you love the full-bodied aroma and umami-rich flavor of traditional natto, the Classic version is for you. Enjoy natto’s health benefits, your way!
