PROPERTIES AND BENEFITS OF VITAMIN K
While the term vitamin K1 refers to a single compound, vitamin K2 counts as a group of substances. Phylloquinone, or vitamin K1, has the chemical formula C31H46O2. Menaquinones have designations of MK-4 through MK-13 with different compositions. Humans mainly consume phylloquinone, which appears in leafy greens. However, they also receive menaquinones from the bacteria in animal-based and fermented products. In its pure form, vitamin K appears as a light yellow oil or yellow crystals. It remains stable when exposed to air and moisture, but not during exposure to sunlight.
The scientific community has limited data on the biological availability of phylloquinone and menaquinones. Most research on vitamin K examines phylloquinone, so little is known about menaquinones and the body. Phylloquinone metabolizes quickly compared to other fat-soluble vitamins, and the body gets rid of a large amount of an oral dose. Menaquinones form from gut bacteria, but experts do not understand how much of them contribute to vitamin K requirements. Most people do not show signs of vitamin K deficiency.
Vitamin K consumption mainly benefits people with a deficiency. Without enough vitamin K, the human body cannot create prothrombin. This substance promotes blood clotting and bone formation. People with conditions that affect vitamin K absorption can have bleeding due to deficiency. In people with normal levels of the substance, vitamin K supplementation could improve bone and heart health.
Use of Vitamin K in the Food and Nutrition Industry
The American and Canadian food industries generally use vitamin K to fortify meal replacements. Canada requires producers to add vitamin K to infant formula and food for low-energy diets. While the United States has no requirement, many companies add it to energy bars and drinks. As research on vitamin K continues, companies may add it to more products.
Companies that produce supplements add various forms of vitamin K to their products. Dietary supplements can include phylloquinone or the menaquinones MK-4 and MK-7. Many multivitamins include vitamin K in an amount below 75 percent of the recommended daily amount. However, standalone vitamin K supplements have very high amounts. Consumers take these nutraceuticals to relieve a vitamin K deficiency.
