                          Feature

                          Vitamin K2, also known as menadione, is a fat-soluble vitamin. K2 exists in many forms, including tetraene menadione (MK-4), hexene menadione (MK-6), and heptaene menadione (MK-7).
                          Compared with other forms, MK-7 has a high absorption efficiency and is currently the main application form.
                          Our company supplies various vitamin raw materials, including vitamin K2 powder and oil.

                          What is the vitamin K2 good for?

                          1. Vitamin K also plays an indispensable and important role in bone health. For example, supplementing with vitamin K2 can effectively relieve nocturnal leg cramps (NLCs), promote bone tissue mineralization, and prevent fractures and osteoporosis.
                          2. It also has the function of reducing the risk of cardiovascular disease and has a potential preventive effect on coronary artery calcification and cardiovascular disease.
                          3. Maintain healthy coagulation function. Vitamin K is an important component for the synthesis of coagulation factors (such as prothrombin), and vitamin K deficiency may lead to coagulation disorders.
