Vitamin K is an essential nutrient that is important for many bodily functions, including blood clotting and bone metabolism. This fat-soluble vitamin is found in a variety of foods, and can also be produced by the body through bacterial fermentation in the large intestine. In this article, we’ll take a closer look at the health benefits of Vitamin K and how to ensure that you’re getting enough of this important nutrient.
What is Vitamin K?
Vitamin K is a group of fat-soluble vitamins that are necessary for blood clotting, bone metabolism, and other important functions in the body. There are two main forms of Vitamin K: Vitamin K1, also known as phylloquinone, and Vitamin K2, also known as menaquinone. Vitamin K1 is found primarily in green leafy vegetables, while Vitamin K2 is found in fermented foods and animal products.
Health Benefits of Vitamin K
Blood Clotting:
Vitamin K plays a crucial role in blood clotting. When a blood vessel is damaged, the body uses a complex process called the coagulation cascade to form a blood clot and stop the bleeding. Vitamin K is necessary for the activation of several proteins involved in this process, including prothrombin and factors VII, IX, and X.
Bone Health:
Vitamin K is essential for bone metabolism and may help prevent osteoporosis. It helps activate osteocalcin, a protein that is necessary for bone mineralization. Studies have shown that low Vitamin K intake is associated with an increased risk of hip fractures in older women.
Heart Health:
Vitamin K may also play a role in heart health by helping to prevent the buildup of calcium in the arteries. This buildup, known as arterial calcification, can increase the risk of heart disease and stroke. Studies have shown that higher Vitamin K intake is associated with a lower risk of cardiovascular disease.
Cancer Prevention:
Some studies have suggested that Vitamin K may play a role in cancer prevention. One study found that high intake of Vitamin K2 was associated with a lower risk of prostate cancer in men, while another study found that high intake of Vitamin K1 was associated with a lower risk of developing liver cancer.
Sources of Vitamin K
Green leafy vegetables:
Kale, spinach, collard greens, and broccoli are all excellent sources of Vitamin K1.
Fermented foods:
Natto, a Japanese dish made from fermented soybeans, is one of the best sources of Vitamin K2. Other fermented foods, such as sauerkraut and kefir, also contain Vitamin K2.
Animal products:
Liver, egg yolks, and some cheeses are good sources of Vitamin K2.
Supplements:
Vitamin K supplements are available in both Vitamin K1 and Vitamin K2 forms. They are often used to treat Vitamin K deficiency or to support bone health.
Supplementing with Vitamin K
While Vitamin K deficiency is relatively rare, some people may be at increased risk of deficiency, including those with malabsorption disorders, liver disease, or those taking certain medications. If you are at risk of Vitamin K deficiency, or if you are pregnant or breastfeeding, you may want to consider taking a Vitamin K supplement. It’s important to talk to your doctor before starting any new supplement regimen. Should you want to supplement we recommend you take a Vitamin K complex that includes Vitamin K1 and K2.
