Vitamin K

Vitamin K is a fat-soluble nutrient that plays a crucial role in blood clotting and bone health. It exists in two primary forms: K1 (phylloquinone) and K2 (menaquinone). Vitamin K1 is primarily involved in the blood-clotting process, ensuring wounds can heal properly and preventing excessive bleeding. Vitamin K2, on the other hand, is important for regulating calcium metabolism and ensuring that calcium is directed to the bones and teeth rather than accumulating in soft tissues. This contributes to strong bones and a reduced risk of osteoporosis.

Dietary sources of vitamin K1 include green leafy vegetables like spinach and kale, while vitamin K2 is found in animal products, supplements and fermented foods. The body can also produce a small amount of vitamin K through gut bacteria.

A deficiency in vitamin K can lead to impaired blood clotting, which increases the risk of bleeding. Ensuring sufficient intake of vitamin K through diet or supplements supports proper blood coagulation, bone health, and overall well-being. However, individuals on blood-thinning medications should consult with a healthcare professional before making significant changes to their vitamin K intake.
