SUPERFOOD FROM JAPAN – Natto is a traditional Japanese food made from fermented soybeans transformed by Bacillus subtilis natto. This natural fermentation process increases B-vitamins and introduces essential nutrients like vitamin K2 and natto kinase. As a fermented Japanese superfood, natto powder offers distinctive umami flavor and health benefits, while reflecting the depth of Japan’s culinary culture.
VERSATILE USE IN A VARIETY OF DISHES – This organic freeze-dried natto powder blends beautifully into everyday meals. Use it in soups like miso, udon, or ramen for rich, probiotic flavor. Sprinkle it over curry, risotto, salads, or pasta, or mix it with sauces like mayo or ketchup to boost taste and nutrition. Note: Add carefully to hot liquids to prevent lumping.
PROBIOTIC AND PREBIOTIC POWER – More than just a probiotic, natto powder also contains prebiotic dietary fiber that supports the growth of good gut bacteria. This dual action makes it a standout among Japanese fermented foods, supporting digestion, immune health, and gut balance naturally.
NUTRIENTS PRESERVED THROUGH FREEZE-DRYING – Our natto powder organic is made from Non-GMO soybeans, fermented and then freeze-dried at -30°C. This method locks in all the natural enzymes, probiotics, and nutrients—without using heat or additives. It’s unseasoned, allowing you to enjoy the pure, authentic flavor of Japanese natto.
