Function
Vitamin K2 MK7 was first isolated from natto, a traditional Japanese food made from fermented beans with a specific bacterium, Bacillus subtilis natto. Several studies have linked natto intake and high levels of MK7 to improved bone health and reduced cardiovascular risk factors.
Application
1. Vitamin K2(MK7)：used for osteoporosis, improving arterial calcification, and treating Parkinson’s disease .
2. MK7 has been shown to promote bone health and help prevent cardiovascular disease in the human body, and the fermentation quality of Bacillus subtilis natto has a decisive influence on its efficacy.
