Vitamin K2 is a fat-soluble vitamin that plays a crucial role in maintaining bone and cardiovascular health. It helps activate proteins that are essential for calcium metabolism, ensuring that calcium is deposited in bones and teeth rather than in arteries and soft tissues. This function is vital for preventing conditions like osteoporosis and arterial calcification. There are several forms of vitamin K2, with the most common being MK-4 and MK-7. MK-4 is found in animal products, while MK-7 is primarily sourced from fermented foods like natto. Including these foods in your diet can help support overall health and well-being.
