7Vitamin K2 Dietary Sources and Supplements
Compared to vitamin K1, vitamin K2 is less common in dietary sources. However, gut bacteria would convert some vitamin K1 into vitamin K2. Fermented foods are the best source of this mineral. Also, high-fat dairy products and organ meats provide a quite significant amount of vitamin K2. In contrast, lean meats are not good dietary sources of this vitamin. [7]
While a deficiency of vitamin K2 is rare, some people may be at a risk of this health issue. In these cases, vitamin K2 supplements may help. Many multivitamins provide both vitamin K1 and K2. You would choose to buy vitamin K in combination with other minerals or as a standalone supplement. Vitamin K2 is often available in the form of MK-4 or MK-7. Since the concentrations can vary, make sure to check the label before buying. Since vitamin K would interact with blood thinners and other medications, consult your doctor before taking these supplements. [8]
