vitamin k and calcium work together to prevent

The first epidemiological studies used food questionnaires to assess daily intake of vitamin K; however, this method has certain limitations. A small RCT in 42 predialysis CKD patients showed that when compared to vitamin D alone, a combination of vitamin K2 and D resulted in favorable results regarding dp-ucMGP reduction but had no impact on progression of VC [84].

VITAMIN K - Uses, Side Effects, and More - WebMD See additional information. The https:// ensures that you are connecting to the MGP belongs to the family of vitamin K-dependent proteins (VKDPs), a group of seventeen proteins involved in the regulation of bone metabolism, blood coagulation, and arterial calcification. In pre-dialysis CKD, data from a few observational studies showed that dp-ucMGP was associated with various surrogate markers of arterial calcification or stiffness. Fusaro M., Tripepi G., Plebani M., Politi C., Aghi A., Taddei F., Schileo E., Zaninotto M., Manna G.L., Cianciolo G. The vessels-bone axis: Iliac artery calcifications, vertebral fractures and vitamin K from VIKI study. In fact, it potentially may have lifesaving implications for many people. What do we need to learn? Cleveland Clinic is a non-profit academic medical center. Its a shorter chain, so it gets filtered through your liver more quickly, Zumpano explains. [103] orally administered a combination of vitamin K1 and K2 (MK-4 and MK-7) in ten HD patients and nine healthy controls and found that, when compared to healthy controls, HD patients exhibited a significantly increased uptake and incorporation of MK-4 into high (HDL) and low density lipoproteins (LDL). See the table below to determine how much vitamin K2 and calcium you should be intaking based on your demographic. All VKDPs have inactive Glu residues that undergo -carboxylation to -carboxyglutamate (Gla), a process requiring vitamin K as a co-factor. Blood thats too thin can make you bruise more easily and even leave you at risk for dangerous internal bleeding. Prevalence and Effects of Functional Vitamin K Insufficiency: The PREVEND Study. Calcium buildup in the arteries around your heart is a huge risk factor for heart disease (5, 6).

Association of the Inactive Circulating Matrix Gla Protein with Vitamin K Intake, Calcification, Mortality, and Cardiovascular Disease: A Review. However, this nutrient offers many other notable advantages to our health, as a proper intake is essential for: Building and maintenance of strong bones Dental health Cardiovascular function Regulation of blood pressure Vitamin K Supplementation for Prevention of Vascular Calcification in Vitamin K2 is a relative newcomer, but early research is turning heads when it comes to health. Currently, there is keen scientific interest on the potential clinical role of vitamin K in the pathogenesis and development of arterial calcification and stiffness in CKD and ESKD. Zumpano helps us understand the health benefits of vitamin K2 and how to get more of it in your diet. Vitamin K was discovered in 1929 as an essential nutrient for blood coagulation, which is the scientific term for blood clotting. Some subsequent studies found that vitamin K supplementation had no effect on bone mineral density. Vitamin K is believed to help by preventing calcium from being deposited in your arteries ( 3 ). Osteoporosis which translates to the phrase porous bones is a common problem in Western countries. Schurgers L.J., Spronk H.M., Skepper J.N., Hackeng T.M., Shanahan C.M., Vermeer C., Weissberg P.L., Proudfoot D. Post-translational modifications regulate matrix Gla protein function: Importance for inhibition of vascular smooth muscle cell calcification. Microcalcifications in early intimal lesions of atherosclerotic human coronary arteries. Most of us arent consuming enough of the foods rich in this vitamin to support our health. This was one of the first interventional studies in this research area to highlight the synergy and interaction between vitamins K and D; however, the small sample size, the short study period, and the low MK-7 dosage should be acknowledged as limitations. Vitamin K is fat-soluble, which means low fat and lean animal products dont contain much of it. Vitamin D plays a role in reducing inflammation and assisting in cell growth and immune function (4). Maresz K. (2015). This vitamin is rare in the Western diet and hasnt received much mainstream attention. But research is showing that calcium doesnt act alone. The same is true of vitamin K. K vitamins are fat-soluble, meaning they dissolve in fats and oils. Vitamin K2: What It Is and Its Benefits - Cleveland Clinic performed a meta-analysis of 21 studies and 222,592 participants and showed that increased dietary intake of either vitamin K1 or K2 was linked with a moderately reduced risk of coronary heart disease, although not with mortality. Only after hepatic vitamin K requirement has been met, the excess vitamin K is transported to extra-hepatic tissues. Vitamin K comes in two forms K1 and K2. Vitamin K isnt unique in this regard. Brandenburg V.M., DHaese P., Deck A., Mekahli D., Meijers B., Neven E., Evenepoel P. From skeletal to cardiovascular disease in 12 steps-the evolution of sclerostin as a major player in CKD-MBD.

Roumeliotis S., Roumeliotis A., Panagoutsos S., Giannakopoulou E., Papanas N., Manolopoulos V.G., Passadakis P., Tavridou A. Matrix Gla protein T-138C polymorphism is associated with carotid intima media thickness and predicts mortality in patients with diabetic nephropathy. Subclinical vitamin K depletion is highly prevalent in ESKD patients and has been associated with VC, vascular stiffness, mortality, and CV disease. Seven of these trials, which took fractures into consideration, found that vitamin K2 reduced spinal fractures by 60%, hip fractures by 77%, and all non-spinal fractures by 81% (12). It makes sense for them to be grouped together because they share a lot of common traits.. And clots in your arteries cause heart attacks. But do you know your bones also need vitamin K? Menaquinones can also be produced by bacteria in the human body. In Japan and other parts of Asia, one kind of vitamin K2 (MK-4), is used as a treatment for osteoporosis. Vitamin K exists in three vitamers, phylloquinone (or K1), menaquinone (K2), and menadione (K3); there are several sub-forms of K2 depending on the number of isoprenyl units and the length of the side-chain. You may have heard about vitamin K. It plays a big role in blood clotting, bone health and heart health. The carboxylation of Glu causes significant alterations in the molecular structure of VKDPs, leading to their activation. Vitamin K2 activates the calcium-binding actions of two proteins matrix GLA protein and osteocalcin, which help to build and maintain bones (10). Neradova A., Schumacher S., Hubeek I., Lux P., Schurgers L., Vervloet M. Phosphate binders affect vitamin K concentration by undesired binding, an in vitro study. Bone biomarkers help grading severity of coronary calcifications in non dialysis chronic kidney disease patients. It was also discovered by the dentist Weston Price, who traveled the world in the early 20th century, studying the relationship between diet and disease in different populations. They may grow on different trees and have different tastes, but at the end of the day, theyre all citrus fruits. What is calcium? Murshed M., Schinke T., McKee M.D., Karsenty G. Extracellular matrix mineralization is regulated locally; different roles of two gla-containing proteins. To establish that the product manufacturers addressed safety and efficacy standards, we: We do the research so you can find trusted products for your health and wellness. What are the benefits of taking magnesium? Other supplements like vitamin K2 (VitK2) and magnesium (Mg) could contribute to the maintenance of skeletal health. and E.D. Vitamin K1 is involved in blood coagulation, and vitamin K2 benefits bone and heart health. Moe S.M., ONeill K.D., Reslerova M., Fineberg N., Persohn S., Meyer C.A. Roumeliotis S., Dounousi E., Salmas M., Eleftheriadis T., Liakopoulos V. Vascular Calcification in Chronic Kidney Disease: The Role of Vitamin K- Dependent Matrix Gla Protein. This crucial alteration in the pharmacology of MK-7 in uremia might partially explain the negative RCTs regarding MK-7 supplementation in predialysis CKD patients. Evidence to support vitamin K supplementation is too preliminary and contradictory to make recommendations. Moreover, in a cohort of 188 HD patients, patients with more severe degrees of VC as assessed by Adragao and total calcification score had significantly lower plasma dp-cMGP levels, whereas dp-ucMGP was not correlated with the extent of VC [72]. Whats in a name? Oneill W.C., Lomashvili K.A. However, even 460 g per day of vitamin K2 intake failed to normalize dp-ucMGP levels in maintenance dialysis patients, and might therefore be considered under-therapeutic. Most people have never heard of vitamin K2. Moreover, the population was heterogenous regarding dialysis modality, and circulating dp-ucMGP decreased by only 40% in the vitamin K group. In advanced CKD, the consequences of kidney dysfunction (particularly mineral dysregulation, inflammation and accumulation of uremic toxins) favor the osteogenic transition of vascular smooth muscle cells, through the activity of cytokines and enzymes such as Fibroblast Growth Factor-23 [15,16], osteocalcin [17,18,19], sclerostin [20,21,22], bone-morphogenetic proteins [16,23,24,25], osteoprotegerin [22,26,27,28], RUNX2 [16] and calcium-sensing receptor [29,30] that trigger the osteoblastic differentiation of VSMCs, thus promoting the onset and development of VC [31,32,33,34]. randomly divided 53 maintenance HD patients into daily intake groups of 45, 135 or 360 g MK-7 for 1.5 month, and found that dp-ucMGP was time- and dose-dependently reduced in all three groups (a 17.9%, 36.7% and 61.1% reduction in the 45, 135 and 360 groups, respectively) [79]. When calcium builds up in your body, it can lead to hardening (or calcification) of your tissues, organs and blood vessels. In HD populations, two independent studies showed that plasma dp-ucMGP was predictive of vitamin K status and significantly correlated with abdominal aortic calcification [68,69], whereas in a cohort of 120 maintenance HD patients, Hermans et al. However, some researchers are not convinced. Currently-ongoing interventional RCTs regarding vitamin K supplementation in these populations include the Inhibit Progression of Coronary Artery Calcification with Vitamin K1 in Hemodialysis participants (iPACK-HD) [89], Treatment to Reduce Vascular Calcification in Hemodialysis Patients Using Vitamin K (TReVasc-HDK) [90], Vitamin K1 to Slow Progression of Vascular Calcification in HD Patients (VitaVasK) [91], Vitamin K to Slow Progression of Cardiovascular Disease Risk in Hemodialysis Patients (Vita-K n CKD, registered on clinicaltrials.gov, reference number {"type":"clinical-trial","attrs":{"text":"NCT03311321","term_id":"NCT03311321"}}NCT03311321), Universidad Catlica de Salta-Vitamin K2 Supplementation and Vascular Calcification (UCASAL-VITK, registered on clinicaltrials.gov with reference number {"type":"clinical-trial","attrs":{"text":"NCT04539418","term_id":"NCT04539418"}}NCT04539418 and the first to assess intravenous supplementation of MK-7 in HD patients), and the Vitamin K in Peritoneal Dialysis (VIKIPEDIA) study, the first to assess MK-7 supplementation in PD (registered on clinicaltrials.gov, reference number {"type":"clinical-trial","attrs":{"text":"NCT04900610","term_id":"NCT04900610"}}NCT04900610). MGP was the first identified inhibitor of VC in experimental studies and has the ability to prevent as well as to reverse calcification of the vessel walls [40,41,42] through several pathways. And should you be taking a vitamin K supplement? Vitamin K2 plays an essential role in bone metabolism, and studies suggest that it can help prevent osteoporosis and fractures. Abstract The K vitamins, a group of napthoquinones, are required for the carboxylation of a limited number of proteins including the bone matrix protein osteocalcin. Hackeng T.M., Rosing J., Spronk H.M., Vermeer C. Total chemical synthesis of human matrix Gla protein. Instead of calcium building up in our arteries, this vital mineral can reach our bones and teeth to ensure their strength and health. It increases the expression of those vitamin K-dependent proteins that regulate calcium. Think of vitamin K as a collection of vitamins that play a similar role in your health. Vitamins A and D are also believed to play an important role here, working synergistically with vitamin K2 (18). Vitamin D and calcium supplements: Take them or leave them? sharing sensitive information, make sure youre on a federal However, although the deleterious effects of VC in CKD and ESKD patients have been known for a long time the pathophysiology of this process was not fully elucidated until recently. However, this powerful nutrient plays an essential role in many aspects of your health. Pre-dialysis CKD patients are at a much greater risk of experiencing a fatal CV event than of progression to end-stage kidney disease (ESKD) requiring dialysis [1] and in ESKD the CV risk is further exacerbated [2]. Lees J.S., Chapman F.A., Witham M.D., Jardine A.G., Mark P.B. Some scientists are convinced that people at risk of heart disease should regularly use vitamin K2 supplements. Human vascular smooth muscle cells undergo vesicle-mediated calcification in response to changes in extracellular calcium and phosphate concentrations: A potential mechanism for accelerated vascular calcification in ESRD. Vitamin K, particularly as vitamin K 2, is nearly nonexistent in junk food, with little being consumed even in a healthy Western diet. Natural history of vascular calcification in dialysis and transplant patients. The second study in this population, the Vitamin K for kidney transplant organ recipients: investigating vessel stiffness (VIKTORIES) study [83], was a single-center parallel group RCT in which 90 kidney transplant recipients were randomized to 5 mg of menadiol diphosphate (a synthetic form of vitamin K) or a placebo thrice weekly for one year; the outcomes were change in arterial stiffness as assessed by aortic distensibility from magnetic resonance imaging and VC as assessed by computer tomography-based coronary calcification score. Vaccines & Boosters| Testing| Visitor Guidelines| Coronavirus CloseJohns Hopkins Medicine MenuMenu For more than a century, arterial calcification was believed to be a passive, progressive and untreatable process of calcium accumulation in the arterial walls. However, keep in mind that the studies were observational studies, which cannot prove cause and effect. Van Ballegooijen A.J., Pilz S., Tomaschitz A., Grbler M.R., Verheyen N. The synergistic interplay between vitamins D and K for bone and cardiovascular health: A narrative review. Theres still much to be understood about the differences between vitamin K1 and vitamin K2, and research is ongoing. All newborns receive vitamin K injections to prevent the possibility of bleeding, particularly in the brain. Vitamin D: What Is Its Role in Preventing Breast Cancer? Roumeliotis S., Mallamaci F., Zoccali C. Endothelial Dysfunction in Chronic Kidney Disease, from Biology to Clinical Outcomes: A 2020 Update. The circulating inactive form of matrix gla protein is a surrogate marker for vascular calcification in chronic kidney disease: A preliminary report. Vitamin K helps to prevent calcium from accumulating in soft tissues (such as kidneys and blood vessels) by activating the matrix GLA protein. Vitamin K2 has been found to improve survival in patients with liver cancer. Nimptsch K., Rohrmann S., Kaaks R., Linseisen J. Dietary vitamin K intake in relation to cancer incidence and mortality: Results from the Heidelberg cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC-Heidelberg). Vitamin K2 is mainly found in certain animal and fermented foods, which most people dont eat much of. But thats not a hard-and-fast rule. Some early studies are showing that vitamin K2 supplements may reduce fractures and improve bone quality in people with osteoporosis. One of the main regulating proteins in dental health is osteocalcin the same protein that is critical to bone metabolism and is activated by vitamin K2 (16). Think of oranges, grapefruits, limes and lemons. Calcium and calcium supplements: Achieving the right balance Lots of vitamins are named by a single letter but have various subtypes. Furthermore, calcification of arteries and cardiac valves is very common in ESKD, triggering the onset and development of arterio- or atherosclerosis and subsequent CV disease. Oxidative Stress in Patients Undergoing Peritoneal Dialysis: A Current Review of the Literature. There are some foods that are both naturally healthy and rich in vitamin K2.. Do You Really Need to Take Vitamin D Supplements? Those of us invested in our health have probably heard about all the benefits that calcium offers, but did you know we can maximize these benefits by ensuring an adequate intake of vitamin K2? We include products we think are useful for our readers. Witham M.D., Lees J.S., White M., Band M., Bell S., Chantler D.J., Ford I., Fulton R.L., Kennedy G., Littleford R.C. Matrix Gla Protein (MGP) is a 12 kDa protein containing 84 amino-acids, four or five glutamate (Glu) and three serine residues which is secreted by VSMCs in the arterial wall and expressed in the bones, heart, kidneys, cartilage and arteries. MGP binds directly to free circulating calcium, phosphorus, and hydroxyapatite crystals and forms neutralized, inactive complexes that lose their ability to accumulate within the arterial walls [36]. Healthline Media does not provide medical advice, diagnosis, or treatment. Animal foods contain the MK-4 subtype, while fermented foods like sauerkraut, natto, and miso pack more of the longer subtypes, MK-5 to MK-14 (23). Over the age of 70, they need 800 IU of vitamin D each day. and A.K. Its believed that vitamin K2 may play a critical role in dental health, but human studies showing the benefits of supplements in this area are currently lacking. Vitamin D is the most significant nutrient for the proper absorption of calcium. Therefore, the first rule when introducing a novel therapeutic agent, First, do no harm, is probably respected; whether the do good value is supported remains to be elucidated based on the results of current ongoing clinical trials. The thinking is that vitamin K2 has the potential to have more influence on your body because its a longer chain, so your body is slower to absorb and digest it.. Some early research has shown that vitamin K2 may be more effective at clearing out calcium than vitamin K1. Because the mean circulating dp-ucMGP in the vitamin K group was 1173 pmol/L, it became evident that supplementation with vitamin K did not fully restore vitamin K status, and that the dosage might therefore be considered undertherapeutic. Understanding the role of this vitamin (and where to find it!). By activating VKDPs, vitamin K (a group of fat-soluble vitamins) is implicated in the regulation of bone metabolism, blood coagulation, and vascular health. Kaesler N., Magdeleyns E., Herfs M., Schettgen T., Brandenburg V., Fliser D., Vermeer C., Floege J., Schlieper G., Kruger T. Impaired vitamin K recycling in uremia is rescued by vitamin K supplementation. Out of 13 studies, only one failed to show significant improvement. All Rights Reserved. Circulating Dephospho-Uncarboxylated Matrix Gla-Protein Is Associated With Kidney Dysfunction and Arterial Stiffness. Additionally, some research suggests that vitamin K2 supplements may be beneficial for some people. Our team of licensed nutritionists and dietitians strive to be objective, unbiased, honest and to present both sides of the argument. In line with these findings, vitamin K supplements are officially recommended for preventing and treating osteoporosis in Japan (13). Similarly, the Effect of Vitamin K2 (MK7) on Cardiovascular and Bone Disease in Dialysis Patients (RenaKvit) RCT [87] recently reported that daily treatment with 360 g MK-7 for two years in 21 ESKD patients undergoing either HD or PD failed to show any beneficial effect on aortic stiffness or calcification. Pilkey R.M., Morton A.R., Boffa M.B., Noordhof C., Day A.G., Su Y., Miller L.M., Koschinsky M.L., Booth S.L. Vitamin K and magnesium, which also helps promote calcium deposition in bone, might also be found in the same supplement. Accumulated data from in vitro and in vivo studies has coherently detected local concentrations of dp-ucMGP around calcification sites such as atheromatic lesions and plaques, and circulating levels of dp-ucMGP are strongly correlated with the degree of VC [55,56]. Cardiac calcification in renal patients: What we do and dont know. official website and that any information you provide is encrypted These two nutrients work together in our bodies, says Rebecca Lewis, M.S., R.D.N., dietitian for HelloFresh. However, thus far the results of such supplementation on the progression of VC remain ambiguous and contraindicatory. These two studies showed that even 460 g of vitamin K2 per day failed to restore vitamin K status (as reflected by the reduction rate of dp-ucMGP) in dialysis patients, and provided the rationale for designing randomized controlled trials (RCTs) in dialysis patients. If You Take Vitamin D, You May Need This Other Vitamin to Reduce - MSN An adequate intake of vitamin K 2 has been shown to lower the risk of vascular damage because it activates matrix GLA protein (MGP), which inhibits the deposits of calcium on the walls. Klotho deficiency causes vascular calcification in chronic kidney disease. Calcium Supplement Dangers? | Andrew Weil, M.D. - DrWeil.com Policy. They work differently in your body and come from different food sources. Foods we can add to our diet that are rich sources of calcium include: Those not receiving enough calcium from our diet may need to take daily calcium supplements to avoid a deficiency in this nutrient. Vitamin D and Calcium Supplementation to Prevent Fractures https://ods.od.nih.gov/factsheets/Calcium-HealthProfessional/. Because CKD patients suffer from accelerated calcification, several researchers have aimed to investigate the possible association between poor vitamin K status as assessed by dp-ucMGP and VC. El Borolossy R., El-Farsy M.S. Placental transfer of vitamin K1 in preterm pregnancy. Moreover, there are numerous knowledge gaps and research questions that have remained unanswered to date regarding the supplementation of vitamin K in these populations, including the best form, dosage, duration of treatment, method of measuring vitamin K status, and expected response to treatment. Careers, Unable to load your collection due to an error. A true vitamin K deficiency, which is marked by an inability of blood to clot normally and easy bruising, is rare. Subclinical vitamin K deficiency in hemodialysis patients. Men over 70 and women over 50 need 1200 mg of calcium a day . Bostrom K., Tsao D., Shen S., Wang Y., Demer L.L. Van Ballegooijen A.J., Cepelis A., Visser M., Brouwer I.A., Van Schoor N.M., Beulens J.W. Osteocalcin triggers a mechanism that stimulates the growth of new bone and new dentin, which is the calcified tissue underneath the enamel of your teeth (17). When it comes to calcium metabolism, vitamins D and K work together. ), 2Department of Nephrology, Faculty of Medicine, School of Health Sciences, University of Ioannina, 45110 Ioannina, Greece; moc.oohay@inudtsirkina (A.D.); moc.liamtoh@sostikht (A.K.). But a certain amount of clotting-ability in your blood is important for your health. But in reality, vitamin D, vitamin K and calcium all actually work together." Vitamin K helps activate a protein called osteocalcin, which binds to calcium to build bones. Calcium is an essential mineral that's primarily known for its role in supporting bone health. included thirteen RCTs involving 2162 patients and fourteen longitudinal studies involving 10,726 patients, and showed that exogenous supplementation with vitamin K caused a significant 9.1% reduction in the degree of VC, attributed to a 44.7% decrease in plasma dp-ucMGP concentration [81]. After the treatment period, the authors found no effect on either VC or vascular stiffness between the groups. Proper Calcium Use: Vitamin K2 as a Promoter of Bone and Cardiovascular Health. Many of the studies conducted thus far are limited by flaws in the design or a small number of participants. Calcium and P are very important for lactating does and growing kids. In addition, accumulation of uremic toxins and enhanced oxidative stress and inflammation suppress the concentration and expression of calcification inhibitors, such as Klotho [15,16,35] and pyrophosphates [36,37,38]. Licensee MDPI, Basel, Switzerland. In CKD, vitamin K deficiency is highly prevalent, starts early, progresses along with disease progression to ESKD, and increases the risk of accelerated VC and CV morbidity and mortality. Health risk of osteoporosis is increasing in Korean women and there were many trials to reduce and prevent osteoporotic fracture risk (1, 2).Vitamin K plays a role in bone metabolism and may decrease the risk of fracture (3, 4).Vitamin K also acts synergistically with Vitamin D on bone mineral density (BMD) and positively influences the balance of calcium, a key mineral in bone .
