European Food Safety Authority. The K vitamins, a group of napthoquinones, are required for the carboxylation of a limited number of proteins including the bone matrix protein osteocalcin. [, Jagannath VA, Fedorowicz Z, Thaker V, Chang AB. Vitamin K primarily functions as a coenzyme, a protein that speeds up a reaction, for the synthesis of proteins involved in blood clotting and bone metabolism. . Blood 2004) Two recent studies involving more than 100 subjects have shown that patients treated with oral anticoagulants have double the calcification of patients not on these vitamin K-blocking drugs. Compilation of a provisional UK database for the phylloquinone (vitamin K1) content of foods. In a 3-year study of 181 postmenopausal women, one-third were given a supplement containing vitamin D, one-third got a supplement providing both vitamin K1 and D, and one-third were given a placebo. Foods providing 20% or more of the DV are considered to be high sources of a nutrient, but foods providing lower percentages of the DV also contribute to a healthful diet. Some research indicates that high serum levels of undercarboxylated osteocalcin are associated with lower bone mineral density [5,28]. Vitamin K is present in most multivitamin/multimineral supplements, typically at values less than 75% of the DV [18]. Before K2 tells you where to put calcium. Inadequate calcium intake can lead to decreased bone mineral density, which can increase the risk of bone fractures. The administration of vitamin D and/or calcium along with vitamin K could partly explain why some studies have found that vitamin K supplementation improves bone health while others have not. The other type, menaquinones, are found in some animal foods and fermented foods. Other published studies have found a detrimental impact for calcium supplementation on womens cardiovascular health, too. Matrix Gla-protein, a vitamin K-dependent protein present in vascular smooth muscle, bone, and cartilage, is the focus of considerable scientific research because it might help reduce abnormal calcification [9].

Integrative Medicine: A Clinician's Journal, http://www.cardiovascularultrasound.com/content/12/1/34, http://www.hindawi.com/journals/ijvm/2012/903107/, http://www.seemyheart.org/ultrasound-faqs/, Minor as a direct dietary source of vitamin K, Minor as a direct dietary source of vitamin K in Europe, the United States, and Australia, Long-chain menaquinones (eg, MK-10MK-13). J Nutr 2004), Special K Benefits for Postmenopausal Women: Combating the Calcification Paradox. [, Booth SL, Dallal G, Shea MK, Gundberg C, Peterson JW, Dawson-Hughes B. In its inactive form, this protein is associated with various markers of cardiovascular disease including increased arterial stiffness, vascular and valvular . People taking warfarin and similar anticoagulants need to maintain a consistent intake of vitamin K from food and supplements because sudden changes in vitamin K intakes can increase or decrease the anticoagulant effect [45]. Before The entire skeleton is replaced every 7 to 10 years. Other problems from calcium and vitamin D deficiencies include: K1 had no beneficial effects. VKDB is associated with bleeding in the umbilicus, gastrointestinal tract, skin, nose, or other sites [7,24,25]. Otherwise, orlistat does not usually have a clinically significant effect on vitamin K status, although clinicians usually recommend that patients taking orlistat take a multivitamin supplement containing vitamin K [49-51]. 2012 Feb;23(2):705-14. doi: 10.1007/s00198-011-1594-1. Vitamin K, particularly as vitamin K2, is nearly nonexistent in junk food, with little being consumed even in a healthy Western diet. The absorption rate of phylloquinone in its free form is approximately 80%, but its absorption rate from foods is significantly lower [2]. If you think you may have a medical emergency, call your doctor or dial 911 immediately. [, Rejnmark L, Vestergaard P, Charles P, Hermann AP, Brot C, Eiken P, et al. This narrative review summarizes the most recent data on Ca, vitD, vitK2 and Mg supplementation and age-related bone and muscle loss. Seven of the 13 trials also had fracture data that were combined in a meta-analysis. Just as lethal is arteriosclerosis, hardening of the arteries due to calcium deposits in their muscular midsection. Limited research suggests that long-chain MKs may have higher absorption rates than phylloquinone from green vegetables [7]. Washington, DC: U.S. Government Printing Office; 2010. Also, pulse-wave velocity showed a statistically significantly decrease after 3 years for the vitamin K2 (MK-7) group, but not for the placebo group, demonstrating an increase in the elasticity and reduction in age-related arterial stiffening. Vitamin K functions as a coenzyme for vitamin K-dependent carboxylase, an enzyme required for the synthesis of proteins involved in hemostasis (blood clotting) and bone metabolism, and other diverse physiological functions [3,5]. DRI is the general term for a set of reference values used for planning and assessing nutrient intakes of healthy people. 1. The site is secure. (Bgel S. Vitamin K2 also teams up with vitamin D3 to increase the production of Gla-proteins, including osteocalcin in osteoblasts (the cells that build bone), while also inhibiting the production of osteoclasts (the cells that break down bone). doi: 10.1038/ejcn.2009.83. Why You Need Vitamin D and Calcium - Dr. Axe Wien Med Wochenschr. For a general overview of Vitamin K, see our consumer fact sheet on Vitamin K. "Vitamin K," the generic name for a family of compounds with a common chemical structure of 2-methyl-1,4-naphthoquinone, is a fat-soluble vitamin that is naturally present in some foods and is available as a dietary supplement [1]. Vitamin K2: Everything You Need to Know - Healthline [, Binkley N, Harke J, Krueger D, Engelke J, Vallarta-Ast N, Gemar D, et al. Dietary intake of menaquinone is associated with a reduced risk of coronary heart disease: the Rotterdam Study. So, if you have a lot of calcium, you need vitamin K2 to direct it. (Geleijnse JM, Vermeer C, et al. Thromb Haemost 2007; Bugel S. Proc Nutr Soc 2003). Seely S. Is calcium excess in western diet a major cause of arterial disease? Karpiski M, Popko J, Maresz K, Badmaev V, Stohs SJ. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). Epub 2018 Jul 26. This explains why patients on anticoagulants, such as Warfarin, must avoid vitamin K supplementation. Major GC, Alarie F, Dor J, Phouttama S, Tremblay A. Supplementation with calcium + vitamin D enhances the beneficial effect of weight loss on plasma lipid and lipoprotein concentrations. Beulens JW, Booth SL, van den Heuvel EG, Stoecklin E, Baka A, Vermeer C. The role of menaquinones (vitamin K2) in human health. Several food sources of vitamin K are listed in Table 2. Deficiency is more likely in people with digestive problems such as celiac disease, irritable bowel disease, or who have had intestinal bypass surgery, since vitamin K is a fat-soluble nutrient, and these conditions increase the likelihood of fat malabsorption. and transmitted securely. (Iribarren C, Sidney S. JAMA 2000), Fortunately, one of the vitamin K2-dependent proteins, matrix Gla-protein (MGP) is the strongest inhibitor of tissue calcification presently known. Further, due to modern manufacturing processes, the vitamin K content, particularly the vitamin K2 content, of the food supply today has significantly dropped, making vitamin K2 supplements a more reliable way to secure adequate intake.12 By striking the right balance in intake of calcium and K2, it may be possible to fight osteoporosis and simultaneously prevent the calcification and stiffening of the arteries. and transmitted securely. Ferland G. Vitamin K. In: Erdman JW, Macdonald IA, Zeisel SH, eds. Demer LL, Tintut Y. Vascular calcification: pathobiology of a multifaceted disease. There are three main types of vitamin K: vitamin K1 (phytonadione) is the natural form found in plants; vitamin K2 (menaquinones) is made by the human gut, and vitamin K3 (menadione) is the water-soluble form that is made for use in supplements. Summary Naturally occurring forms of vitamin K include phylloquinone (vitamin K 1) and a family of molecules called menaquinones (MKs or vitamin K 2 ). In 2006, Cockayne and colleagues conducted a systematic review and meta-analysis of randomized controlled trials that examined the effects of vitamin K supplementation on bone mineral density and bone fracture [35]. Those benefits are why adequate daily intakes for calcium have been established. You should always speak with your doctor before you start, stop, or change any prescribed part of your care plan or treatment. Because vitamin K is required for the carboxylation of osteocalcin in bone, vitamin K deficiency could also reduce bone mineralization and contribute to osteoporosis [23]. [. The only clinically significant indicator of vitamin K status is prothrombin time (the time it takes for blood to clot), and ordinary changes in vitamin K intakes have rarely been shown to alter prothrombin time [5]. Osteocalcin: the vitamin K-dependent Ca2+-binding protein of bone matrix. Effect of vitamin K supplementation on bone loss in elderly men and women. However, in subgroup analyses, calcium had no effect on femoral neck BMD. The combined effect of vitamin K and calcium on bone mineral density in Michalsson K, Melhus H, Warensj Lemming E, Wolk A, Byberg L. Long term calcium intake and rates of all cause and cardiovascular mortality: community based prospective longitudinal cohort study. Cardiovascular disease is not just about cholesterol, which, if oxidized, can cause atherosclerosis, the formation of plaques on the innermost wall of the arteries. Worldwide, a large group of people is prescribed to a supplemental regime of both vitamin D and calcium. Schurgers LJ, Spronk HM, Soute BA, Schiffers PM, DeMey JG, Vermeer C. Regression of warfarin-induced medial elastocalcinosis by high intake of vitamin K in rats. The https:// ensures that you are connecting to the In nature, vitamin K is found in primarily in two forms K1 (phylloquinone) and K2 (menaquinone). These findings might be particularly relevant for patients with chronic kidney disease because their rates of vascular calcification are much higher than those of the general population [9]. Newer perspectives on calcium nutrition and bone quality. However, vitamin K deficiency results in inadequate activation of MGP, which greatly impairs the process of calcium removal and increases the risk of calcification of the blood vessels.4852 Because that calcification occurs in the vessel walls, it leads to thickening of the wall via calcified plaques (ie, to the typical progression of atherosclerosis), which is associated with a higher risk of cardiovascular events. Vitamin K - Harvard T.H. Chan School of Public Health Vitamin K, particularly vitamin K2, is essential for calcium use, helping build strong bones and inhibiting arterial calcification.35, Vitamin K is a cofactor for 1 enzyme, -glutamylcarboxylase, which -carboxylates certain glutamic-acid residues posttranslationally in a number of vitamin Kdependent (VKD) proteins. Both forms of vitamin K, K1 and K2, are essential in maintaining blood hemostasis and optimal bone and heart health through the role they play in inducing calcium use by proteins. Effect of calcium-based versus non-calcium-based phosphate binders on mortality in patients with chronic kidney disease: an updated systematic review and meta-analysis. Theuwissen E, Smit E, Vermeer C. The role of vitamin K in soft-tissue calcification. These limited studies indicate that joint supplementation might be beneficial for cardiovascular health. Vitamin K transport across the placenta is poor, increasing the risk of vitamin K deficiency in newborn babies [3].
