Vitamin K2 is believed to help prevent the calcification of arteries, which can contribute to the development of heart disease. Additionally, natto contains a compound called nattokinase, which has been studied for its potential to support healthy blood clotting and circulation.

3. Gut Health

As a fermented food, natto is rich in beneficial bacteria known as probiotics. These microorganisms can help to support a healthy balance of gut flora, which is important for digestion, immune function, and overall well-being. Consuming fermented foods like natto may contribute to improved gut health and enhanced nutrient absorption.

4. Nutrient Density

In addition to vitamin K2, natto provides a range of essential nutrients, including iron, manganese, copper, and zinc. These minerals play various roles in the body, such as supporting the immune system, energy production, and antioxidant defenses. Natto’s nutrient density makes it a valuable addition to a balanced diet, especially for individuals with specific nutrient needs.
