Vitamin K2, a fat-soluble vitamin also known as menaquinone, was long thought to be a different version of the more commonly known Vitamin K1 (phylloquinone, best known for its role in clotting). But recent studies have shown that poor Vitamin K2 status is associated with a number of other health issues, including increased risk of coronary artery disease and frature
. By directing calcium from soft tissues into your bones, K2 reduces soft-tissue calcificiation, including hardening of the arteries (atherosclerosis), and increases bone density.
Studies also suggest that Vitamin K2 improves insulin resistance in older men
, can be beneficial for patients with leukemia
, and may even help patients with Parkinson's by improving electron transport within mitochondria
Vitamin K2 is found in fermented products, organ meats, and high-fat dairy products or eggs from animals fed on green grass and plants. The most potent dietary source of K2 is natto
, is a fermented soybean dish popular in areas of Japan. Intestinal bacteria produce some Vitamin K2, although the degree to which bacteria-produced intestinal K2 is absorbed appears to be under debate. However, evidence suggests that factors such as antibiotic use
and gastrointestinal disorders such as Crohn's disease
can reduce K2 status.
