Natto helps the body maintain a healthy metabolic system and at the same time supports a healthy circulatory system. In doing so, there is proper blood oxygenation, resulting in healthy energy levels. Natto supports the circulatory system by maintaining blood viscosity and maintaining healthy blood flow.
