Appearance: Vitamin K2 MK7 is a yellow, crystalline powder that is soluble in fat but insoluble in water.
Function: Vitamin K2 MK7 is a form of vitamin K that is important for the activation of proteins involved in blood coagulation and the regulation of calcium metabolism in the body. It is also important for maintaining bone health and preventing calcification of blood vessels.
Application: Vitamin K2 Pure is commonly used as a dietary supplement, typically in the form of capsules or tablets. It is often recommended for individuals who are at risk for vitamin K deficiency, which can occur in people with certain medical conditions or who are taking certain medications. It is also sometimes used to support bone health in postmenopausal women and to support cardiovascular health.
100% all-trans form: Vitamin K2 MK7 is available in different forms, including the 100% all-trans form, which is the natural, biologically active form of the vitamin. This form is typically preferred over the synthetic cis form, which is less stable and less effective. Supplements that contain the 100% all-trans form of Vitamin K2 MK7 are typically labeled as such.
Overall, Vitamin K2 Pure is an important nutrient with a wide range of potential health benefits. As with any supplement, it is important to talk to your healthcare provider before starting to take Vitamin K2 MK7 to ensure that it is safe and appropriate for you.
