Origin & History
Japanese Natto Beans are a traditional superfood made from Glycine max soybeans fermented with Bacillus subtilis bacteria. Known for their strong aroma, sticky texture, and unique flavor, Natto is a nutritional powerhouse packed with probiotics, vitamin K2, and the enzyme nattokinase, contributing to exceptional cardiovascular and bone health benefits. Revered in Japan for centuries, Natto is a staple in Japanese cuisine and wellness practices.
“Natto has been a staple in Japanese cuisine for over 1,000 years, valued for its nutritional benefits and cultural significance. Traditionally eaten as part of breakfast, Natto has long been considered a food for longevity and vitality in Japanese culture, and is recognized in traditional medicine for its role in preventing heart disease and osteoporosis.”Traditional Medicine
Scientific Research
Scientific studies highlight nattokinase’s benefits for cardiovascular health, particularly its role in improving blood circulation and reducing clot risk. Research confirms the probiotic benefits of Natto in supporting gut health, and studies also demonstrate the impact of Vitamin K2 (MK-7) in supporting bone health and calcium metabolism.

Frequently Asked Questions
What are Japanese Natto Beans?
Japanese Natto Beans are soybeans fermented with Bacillus subtilis bacteria, producing a sticky, pungent food rich in nattokinase, vitamin K2 (MK-7), and probiotics. They have been a staple of Japanese cuisine for over a thousand years and are recognized globally as a functional food.
How much natto should I eat daily and is it safe?
A typical serving of 30-50 grams daily provides meaningful amounts of nattokinase, vitamin K2, and probiotics. Natto is generally safe for most people, but those on blood-thinning medications should consult their doctor due to nattokinase's fibrinolytic activity and vitamin K2's effects on coagulation.
What makes natto different from regular soybeans?
Fermentation with Bacillus subtilis transforms soybeans by producing nattokinase (a fibrin-dissolving enzyme not found in unfermented soy), dramatically increasing vitamin K2 (MK-7) content, enhancing mineral and isoflavone bioavailability, and introducing beneficial probiotic bacteria. These compounds are largely absent in unfermented soybeans.
