If you observe the above Calculate class, we defined two methods with the same name (AddNumbers), but with different input parameters to achieve method overloading, this is called a compile time polymorphism in c#. Medicine (Baltimore). Araki S, Shirahata A. Vitamin K deficiency bleeding in infancy. Though the dietary intake of vitamin K required for optimal function of all vitamin K-dependent proteins is not yet known, the Linus Pauling Institute recommends taking a multivitamin/mineral supplement and eating at least one cup of dark-green leafy vegetables daily. Vitamin K and childhood leukemia: In the early 1990s, two retrospective studies were published suggesting a possible association between phylloquinone injections in newborns and the development of childhood leukemia and other forms of childhood cancer. Gla-rich protein (GRP), a new vitamin K-dependent protein identified from sturgeon cartilage and highly conserved in vertebrates. Bleeding, vertebral fractures and vascular calcifications in patients treated with warfarin: hope for lower risks with alternative therapies. A practical approach to minimize the interaction of dietary vitamin K with warfarin. To date, observational studies have failed to unequivocally support an association between circulating menaquinone (MK-7 and MK-4) levels and fracture risk (15, 61). Using compile-time polymorphism, we can perform different tasks with the same method name by passing different parameters. The protein localizes to the nucleus where it may form either a homodimer or a heterodimer with estrogen Nutr Metab Cardiovasc Dis. (PubMed), 103. Pediatrics. Harshman SG, Finnan EG, Barger KJ, et al. (PubMed), 29. This analysis did not find circulating phylloquinone to be linked with incident cardiovascular disease (83). A virtual function is a member function that is declared in the base class using the keyword virtual and is re-defined (Overridden) in the derived class. Jullien S. Vitamin K prophylaxis in newborns. One of the hallmarks of cardiovascular disease is the presence of atherosclerotic plaques in arterial walls. 2006;17(8):1122-1132. Symptoms include easy bruising and bleeding that may be manifested as nosebleeds, bleeding gums, blood in the urine, blood in the stool, tarry black stools, or extremely heavy menstrual bleeding. 2014;17(3):237-239. Booth SL, Tucker KL, Chen H, et al. A meta-analysis of controlled clinical trials found that vitamin K supplementation reduced dp-ucMGP (7 trials), reduced ucOC (4 trials), and decreased progression of vascular calcification (3 trials) (113).

Linus Pauling Institute This VKDP also appears to promote angiogenesis (formation of new blood vessels) during cardiac valve degeneration and tumor growth (22, 23). An important indirect drug interaction between dronedarone and warfarin that may be extrapolated to other drugs that can alter gastrointestinal function. It only serves as a placeholder. The Journal of the Neurological Sciences provides a medium for the prompt publication of original articles in neurology and neuroscience from around the world. A meta-analysis of the results of 11 published studies found that oral anticoagulation therapy was associated with a very modest reduction in BMD at the wrist and no change in BMD at the hip or spine (77). (PubMed), 53. The Association for Academic Surgery is widely recognized as an inclusive surgical organization. (PubMed), 90. (PubMed), 28. Baltimore: Williams & Wilkins; 1999:363-380. It may also play important roles in the developing and aging nervous system (reviewed in 25). Undercarboxylation of osteocalcin in human bone and serum has been linked to poor vitamin K status. 2012;26(1):1-14. Individuals taking anticoagulatory drugs like warfarin and those who are vitamin K deficient should not take vitamin E supplements without close medical supervision because of the increased risk of hemorrhage (excessive bleeding) (131). 2003;73(1):21-26.

Vitamin K intake and osteocalcin levels in women with and without aortic atherosclerosis: a population-based study. Replacing dietary saturated fats like butter and cheese with monounsaturated fats found in olive oil and canola oil will increase dietary vitamin K intake and may decrease the risk of cardiovascular disease. Schurgers LJ, Uitto J, Reutelingsperger CP. Clin Nutr. No tolerable upper intake level (UL) has been established for vitamin K (47). Vitamin K deficiency in newborns may result in a bleeding disorder called vitamin K deficiency bleeding (VKDB) of the newborn (reviewed in 36). The anticoagulant effect of vitamin K antagonists (e.g., warfarin) may be compromised by very high dietary or supplemental vitamin K intake. Osteoporos Int. 2013;2(6):e000364. Huntingtin is a disease gene linked to Huntington's disease, a neurodegenerative disorder characterized by loss of striatal neurons. Booth SL. At present, the potential role for supplemental menaquinones on bone health still needs to be established in large, randomized, and well-controlled trials. Annu Rev Nutr. Vitamin K antagonist anticoagulant usage is associated with increased incidence and progression of osteoarthritis. A cross-sectional study among 719 Japanese older adults found dietary intake of vitamin K to be inversely associated with knee osteoarthritis (117). We own and operate 500 peer-reviewed clinical, medical, life sciences, engineering, and management journals and hosts 3000 scholarly conferences per year in the fields of clinical, medical, pharmaceutical, life sciences, business, engineering and technology. In humans, defective MGP gene has been linked to Keutel syndrome, a rare inherited condition characterized in particular by abnormal cartilage calcification and pulmonary artery stenosis (narrowing). (PubMed), 25. (PubMed), 70. [Internet]. The US Food and Drug Administration (FDA) has not authorized any health claims for any forms of vitamin K. Although allergic reactions are possible, there is no known toxicity associated with high doses (dietary or supplemental) of the phylloquinone (vitamin K1) or menaquinone (vitamin K2) forms of vitamin K (47). Card DJ, Gorska R, Harrington DJ. However, in several randomized, placebo-controlled intervention studies conducted in young girls (67, 68)and postmenopausal women (69), vitamin D supplementation failed to decrease ucOC/OC ratios or show any additive effect on ucOC/OC lowering by supplemental vitamin K. Vitamin K1 supplementation: The review of five randomized clinical trials that assessed the effect of phylloquinone (vitamin K1) supplementation on hip BMD using doses ranging from 200 g/day to 5,000 g/day for durations of 12 to 36 months found little promising benefit for bone health (15). Am J Clin Nutr. BMJ. None of the studies were designed to assess the effect of phylloquinone on osteoporotic-related fractures. A three-year, double-blind, controlled trial investigated the potential effect of vitamin K on the progression of coronary calcification in 401 older, community-dwelling adults (ages, 60-80 years) free of cardiovascular disease at baseline (106). Booth SL, Mayer J. Warfarin use and fracture risk. Shea MK, Kritchevsky SB, Hsu FC, et al. Although circulating dp-ucMGP was correlated to various markers of vitamin K status, no association with measures of coronary artery calcification were found (107).

A longitudinal study of 1,180 US adults (mean age, 62 years) found that low plasma concentrations of phylloquinone (0.5 nM) at baselineindicative of a subclinical vitamin K deficiencywere associated with a 56% increase in risk of knee osteoarthritis after 30 months compared to those with higher plasma concentrations (119). The Journal of the American Academy of Dermatology (JAAD), the official scientific publication of the American Academy of Dermatology (AAD), aims to satisfy the educational needs of the dermatology community.As the specialty's leading journal, JAAD features original, peer-reviewed articles emphasizing: In the US, both phylloquinone and menaquinones are available without a prescription in multivitamin, single-nutrient, or multiple-nutrient supplements in varying doses; vitamin K content of multivitamins typically range from 20 to 120 g per tablet (128). Ardell S, Offringa M, Ovelman C, Soll R. Prophylactic vitamin K for the prevention of vitamin K deficiency bleeding in preterm neonates. Shea MK, O'Donnell CJ, Vermeer C, et al. Excess vitamin A appears to interfere with vitamin K absorption, whereas vitamin E may inhibit vitamin K-dependent carboxylase activity and interfere with the coagulation cascade (129). 1993;329(13):905-908. The mitochondrial oxidation of long-chain fatty acids is initiated by the sequential action of carnitine palmitoyltransferase I (which is located in the outer membrane and is detergent-labile) and carnitine palmitoyltransferase II (which is located in the inner membrane and is detergent-stable), together with a carnitine-acylcarnitine In a more recent longitudinal study among 523 older US adults participating in the Health, Aging, and Body Composition Study, those with extremely low plasma concentrations of phylloquinone (<0.2 nM) at baseline had increased progression of knee osteoarthritis over three years, assessed by MRI of articular cartilage and the meniscus; those with higher plasma concentrations experienced no significant progression of knee osteoarthritis (120). Finally, the hydrogenation of vegetable oils may decrease the absorption and biological effect of dietary phylloquinone (reviewed in 2, 9).

In another study that examined the association between circulating MGP and incident cardiovascular events in 577 older men and women followed for a mean period of 5.6 years, the risk of cardiovascular disease (i.e., coronary artery disease, peripheral arterial disease, and cerebrovascular disease) was two- to three-fold greater in subjects in the highest vs. lowest tertile of plasma dephosphorylated and undercarboxylated MGP (dp-ucMGP) (104). Am J Pathol. Proteomics Clin Appl. Functional study of the vitamin K cycle in mammalian cells. (PubMed), 38. Curr Opin Lipidol. 2019;30(8):1543-1559. Moreover, daily phylloquinone supplements of up to 100 g are considered safe for patients taking warfarin, but therapeutic anticoagulant stability may be undermined by daily doses of MK-7 as low as 10 to 20 g (132). Further investigation may seek to evaluate whether phylloquinone supplementation could improve skeletal health in subjects at high-risk for vitamin K inadequacy (e.g., individuals with malabsorption syndromes or cystic fibrosis).

In c#, polymorphism provides an ability for the classes to implement differentmethodscalled through the same name. Rennenberg RJ, Kessels AG, Schurgers LJ, van Engelshoven JM, de Leeuw PW, Kroon AA. Thus, menaquinone contribution to total vitamin K intakes is difficult to estimate and likely to vary between populations with different food consumption practices (2, 125). Vitamin E serum levels and bleeding risk in patients receiving oral anticoagulant therapy: a retrospective cohort study. Protein S can bind and activate receptors of the TAM family that are involved in phagocytosis. Further, the use of cholesterol-lowering medications (like cholestyramine and colestipol), as well as orlistat, mineral oil, and the fat substitute, olestra, may interfere with fat absorption and affect the absorption of fat-soluble vitamins, including vitamin K (137). Lower doses of vitamin K1 for premature infants: The results of two studies of vitamin K levels in premature infants suggest that the standard initial dose of phylloquinone (vitamin K1) for full-term infants (1.0 mg) may be too high for premature infants (44, 45). Current research suggests that the contribution of bacterial synthesis to vitamin K status is much less than previously thought, although the exact contribution remains unclear (16, 127). (PubMed), 127. Osteocalcin (also known as bone Gla protein) is synthesized by osteoblasts (bone-forming cells); the synthesis of osteocalcin is regulated by the active form of vitamin D, 1,25-dihydroxyvitamin D (calcitriol). In a recent meta-analysis of individual participant data from three prospective cohort studies (the Multi-Ethnic Study of Atherosclerosis; the Health, Aging, and Body Composition Study, and the Framingham Offspring Study), a blood phylloquinone concentration less than or equal to 0.5 nmol/L (n=1,081) was associated with a 19% higher risk of all-cause mortality compared to a blood concentration >1.0 nmol/L (n=1,698; 83).

While other studies failed to observe associations between dietary phylloquinone intake and measures of bone strength, BMD, or fracture incidence (51, 52), the cross-sectional study of a cohort of 3,199 middle-aged women found that subjects in the highest quartile of dietary phylloquinone intake had significantly greater hip and lumbar spine BMD than those in the lowest quartile (162 g/day vs. 59 g/day) (53). Matrix gla protein gene polymorphism is associated with increased coronary artery calcification progression. Perhaps because of its limited ability to store vitamin K, the body recycles it through a process called the vitamin K-epoxide cycle (Figure 2). A number of phylloquinone-rich foods are listed in Table 2, with their content in phylloquinone expressed in micrograms (g). Eur J Epidemiol. Secreted by various cell types, such as vascular smooth muscle cells (VSMCs) in arterial vessel walls, MGP appears to be important for the prevention of calcification of soft tissues, including cartilage, vasculature, skin, and trabecular meshwork cells in the eye (15, 99). Bellinge JW, Dalgaard F, Murray K, et al. Additionally, neither phylloquinone nor menaquinone intake was associated with calcification of breast arteries in a cross-sectional study of 1,689 women ages 49-70 years (94). The vitamin K oxidoreductase is a multimer that efficiently reduces vitamin K epoxide to hydroquinone to allow vitamin K-dependent protein carboxylation. Sci Rep. 2014;4:4768. It is not clear whether the AI for vitamin K is enough to optimize the -carboxylation of vitamin K-dependent proteins in bone (see Osteoporosis). Br J Nutr. The AI for infants was based on estimated intake of vitamin K from breast milk (47). Lab Invest. In c#, Polymorphism means providing an ability to take more than one form, and its one of the main pillar concepts of object-oriented programming after encapsulation and inheritance. The vitamin K cycle allows a small amount of vitamin K to be reused many times for protein carboxylation, thus decreasing the dietary requirement. 137. Braam LA, Knapen MH, Geusens P, et al. Clin Biochem. An inverse relationship between vitamin K intake and mortality was reported in a US national survey (NHANES III) of 3,401 participants (79). 2006;136(5):1323-1328. For example, the incidence of vertebral fractures was inversely correlated with lumbar BMD and plasma phylloquinone in a four-year prospective study that included 379 Japanese women ages 30-88 years (57).

More recently, in a prospective study that followed a cohort of 33,289 Dutch men and women for an average of 16.8 years (the EPIC-Netherlands), neither phylloquinone intake nor menaquinone intake at baseline was associated with mortality from cardiovascular disease, coronary heart disease, stroke, or all causes (81). Vitamin K2: There are few studies on associations between menaquinones (vitamin K2) and bone health, perhaps because of the limited number of dietary sources of menaquinone-4 (MK-4), the main form of vitamin K2 present in Western diets.

Vitamin K2 inhibits rat vascular smooth muscle cell calcification by restoring the Gas6/Axl/Akt anti-apoptotic pathway. Vitamin K deficiency is uncommon in healthy adults for a number of reasons: (1) vitamin K is widespread in foods (see Food sources); (2) the vitamin K cycle conserves vitamin K (see Vitamin K oxidation-reduction cycle); and (3) bacteria that normally inhabit the large intestine synthesize menaquinones (vitamin K2), although it is unclear whether significant amounts are absorbed and utilized (see Food sources).

Yet, the authors emphasize that any conclusions from their pooled analysis are limited by the high heterogeneity of the trials with respect to the form and dose of vitamin K utilized, as well as the assays that assessed vascular calcification (113). (PubMed), 13. Viegas CS, Simes DC, Laize V, Williamson MK, Price PA, Cancela ML. While these observational data are interesting, randomized controlled trials are needed to determine whether vitamin K supplementation in those with low vitamin K status might help prevent or treat osteoarthritis.

Adv Nutr. 9. (PubMed), 22. 2021;125(3):319-328. Thus, further investigations are necessary to examine the role of other vitamin K-dependent proteins (e.g., GRP, periostin, Gas6) in human atherosclerotic plaque calcification and to evaluate the effect of supplemental vitamin K on the progression of vascular calcification and risk of cardiovascular disease. Generally, polymorphism is a combination of two words,poly, and another one is morphs. Hakuno D, Kimura N, Yoshioka M, et al. In another earlier Dutch study that examined 4,807 healthy men and women 55 years and older, participants in the highest tertile of menaquinone intake (>32.7 g/day) had a 41% lower risk of incident CHD and a 26% lower risk of all-cause mortality than those in the lowest tertile (<21.6 g/day) (86). 2021;80(5):598-604. Undercarboxylated osteocalcin measured with a specific immunoassay predicts hip fracture in elderly women: the EPIDOS Study. 2021;10(16):e020551. 1995;116(1):117-123. Rishavy MA, Hallgren KW, Wilson LA, Usubalieva A, Runge KW, Berkner KL. Plaque rupture that causes blood clot formation (thrombogenesis) is the usual cause of a myocardial infarction (heart attack) or stroke. These findings have led some experts to suggest the use of an initial phylloquinone dose of 0.3 mg/kg for infants with birth weights of less than 1,000 g (2 lbs, 3 oz), and an initial phylloquinone dose of 0.5 mg would probably prevent hemorrhagic disease in newborns (44). J Biol Chem. Late Binding : (Run time polymorphism) In this, the compiler adds code that identifies the kind of object at runtime then matches the call with the right function definition (Refer this for details). 6: It is less manageable as it performs at compile time. Corvallis, Oregon 97331, phone: 541-737-5075 | fax: 541-737-5077 Several hormones and growth factors, including vitamin D but not vitamin K, regulate osteocalcin synthesis by osteoblasts. (PubMed), 3. ResearchGate is a network dedicated to science and research. Few studies have examined chronic use of warfarin and risk of fracture in older women. Calcification prevention by MGP involved several mechanisms, including the binding to calcium crystals and the inhibition of proteins (bone morphogenic proteins; BMPs) known to promote ectopic bone formation (reviewed in 100). Japanese 2011 guidelines for prevention and treatment of osteoporosis--executive summary. : a systematic review. Atherosclerosis. 116. (PubMed), 56. 2014;50(6):564-568. One study reported no association between long-term warfarin treatment and fracture risk (74), while another one found a significantly higher risk of rib and vertebral fractures in warfarin users compared to nonusers (75). (PubMed), 133. (PubMed), 100. Certain oral anticoagulants, such as warfarin, are known to be antagonists of vitamin K (see Coagulation). 2012;3(2):204-212. 2022;152(4):981-993. If you wish to check foods for their nutrient content, including phylloquinone, search USDAs FoodData Central. The FNB did not consider menaquinone intakes; data on menaquinone consumption are limited (48). (PubMed), 62. 2009;29:89-110. If you observe the above code snippet, we created two classes (Users, Details), and the derived class (Details) is inheriting the properties from the base class (Users). Apalset EM, Gjesdal CG, Eide GE, Tell GS. In a policy statement, the American Academy of Pediatrics recommended that routine vitamin K prophylaxis for newborns be continued because VKDB is life threatening and the risks of cancer are unproven and unlikely (41). 2020;12(3):780. Proc Nutr Soc. Smaller trials in those at high risk for coronary artery disease (108)or with existing aortic valve calcification (109), type 2 diabetes mellitus(110), or kidney disease (111, 112)have reported no benefit of vitamin K2 supplementation on progression of vascular calcification. Also, the phylloquinone content of green vegetables depends on their content in chlorophyll (green pigment), so that outer leaves have more phylloquinone than inner leaves. A high menaquinone intake reduces the incidence of coronary heart disease. Platonova K, Kitamura K, Watanabe Y, et al. Pure Virtual Functions. This polymorphism is also known as late binding, dynamic binding, and overriding. The discovery of vitamin K-dependent proteins in bone has led to research on the role of vitamin K in maintaining bone health. Olson RE. MGP is involved in the inhibition of calcification at various sites, including cartilage, vessel wall, skin elastic fibers, and the trabecular meshwork in the eye (see Vascular calcification) (15, 16). Br J Nutr. 2012;3(2):196-203. Oregon State University, Updated in May 2004 by: Vitamin K1 supplementation retards bone loss in postmenopausal women between 50 and 60 years of age. Maas AH, van der Schouw YT, Beijerinck D, et al. (PubMed), 72. (PubMed), 77. J Am Soc Nephrol. Vitamin K. Adv Nutr. Identified as a ligand of the TAM family of transmembrane tyrosine kinase receptors, Gas6 appears to be a cellular growth regulation factor with cell-signaling activities. Newborn vitamin K prophylaxis: a historical perspective to understand modern barriers to uptake. Newborn infants, in general, have low vitamin K status for the following reasons: (1) vitamin K transport across the placental barrier is limited; (2) liver storage of vitamin K is very low; (3) the vitamin K cycle may not be fully functional in newborns, especially premature infants; (4) the vitamin K content of breast milk is low, and immature gut flora (5, 35). Thus, evidence of a putative benefit of phylloquinone on bone health in older adults is considered weak. (PubMed), 80. Adequate vs. inadequate vitamin K intakes (based on sex-specific AI: 90 g/day for women and 120 g/day for men) were associated with a 22% lower risk of cardiovascular disease (CVD)-related mortality and a 15% lower risk of all-cause mortality. Here, we defined a GetInfo method with avirtual keyword in the base class to allow the derived class to override thatmethodusing theoverride keyword. 2022;145(18):1387-1397. Protein S appears to play a role in the breakdown of bone mediated by osteoclasts. Kaneki M, Hodges SJ, Hosoi T, et al. Maturitas. It has been suggested that increased circulating ucOC/OC ratio could reflect a poor overall nutritional status that would include vitamin D inadequacy, which would explain the above-mentioned observations (67). Dietary vitamin K intakes are associated with hip fracture but not with bone mineral density in elderly men and women. Cochrane Database Syst Rev. Qiu C, Zheng H, Tao H, et al. Osteoporotic fractures are often linked to a reduction in bone mineralization. The risk of childhood cancer after neonatal exposure to vitamin K. N Engl J Med. The effect of menaquinone-7 supplementation on vascular calcification in patients with diabetes: a randomized, double-blind, placebo-controlled trial. Warfarin therapy has also been associated with higher circulating concentrations of dp-ucMGP in a prospective study that examined vascular calcification in subjects with cardiovascular disease (105). Jie KS, Bots ML, Vermeer C, Witteman JC, Grobbee DE. (PubMed), 94. Novel conformation-specific antibodies against matrix gamma-carboxyglutamic acid (Gla) protein: undercarboxylated matrix Gla protein as marker for vascular calcification. Association of dietary vitamin K and risk of coronary heart disease in middle-age adults: the Hordaland Health Study Cohort. 2021;32(1):185-191. Moreover, recent studies have associated use of the vitamin K antagonist drugs with higher risks of osteoarthritis (121)and joint replacement (121)of the knee and hip compared to nonusers. Palmer CR, Bellinge JW, Dalgaard F, et al. Association between vitamin K1 intake and mortality in the Danish Diet, Cancer, and Health cohort. Mutations in this gene are a frequent cause of familial hypertrophic However, because green leafy vegetables are the primary dietary source of phylloquinone and because they are usually part of a balanced diet, high phylloquinone consumption may simply be an indicator of healthy eating habits, which mayrather than phylloquinone itselfaccount for all or part of the association reported in observational studies (56). No effect of vitamin K1 intake on bone mineral density and fracture risk in perimenopausal women. Nutrition. Free. In addition, menaquinone intake was found to be inversely associated with aortic calcification, a major risk factor for CVD (86). Ekelund H, Finnstrom O, Gunnarskog J, Kallen B, Larsson Y. 2013;121(4):692-699. 1993;307(6896):89-91. (PubMed), 44. 2019;64:6-11. 2004;80(1):143-148. (PubMed), 95. Familial heterozygous protein-S deficiency in a patient who had multifocal osteonecrosis. 2014;55(3):345-362. Osteoporos Int. Roman E, Fear NT, Ansell P, et al. A 2019 systematic review and meta-analysis of clinical trials in postmenopausal women or women with osteoporosis found vitamin K supplementationof any formlowered risk of clinical fracture compared to controls (OR, 0.72; 95% CI, 0.55-0.95; 9 trials varying from 6 months to 2 years: 3 using phylloquinone, 5 using MK-4, and 1 using MK-7) (73). Bone. Coutu DL, Wu JH, Monette A, Rivard GE, Blostein MD, Galipeau J. Periostin, a member of a novel family of vitamin K-dependent proteins, is expressed by mesenchymal stromal cells. Vitamin K supplementation and progression of coronary artery calcium in older men and women. Pastori D, Carnevale R, Cangemi R, et al. Gundberg CM, Lian JB, Booth SL. Because suboptimal vitamin K nutritional status may limit carboxylation and result in biologically inactive ucMGP, it has been speculated that vitamin K supplementation may protect against vascular calcification. Vitamin K intake and the risk of fractures: A meta-analysis. All for free. Serum undercarboxylated osteocalcin is a marker of the risk of hip fracture in elderly women. 6. Jane Higdon, Ph.D. Oka H, Akune T, Muraki S, et al. Serum vitamin K1 (phylloquinone) is associated with fracture risk and hip strength in post-menopausal osteoporosis: A cross-sectional study. Exp Eye Res. Robins RS, Lemarie CA, Laurance S, Aghourian MN, Wu J, Blostein MD. JNS places special emphasis on articles that: 1) provide guidance to clinicians around the world (Best Practices, Global Neurology); 2) report cutting-edge science related to neurology (Basic and The Linus Pauling Institute's Micronutrient Information Center provides scientific information on the health aspects of dietary factors and supplements, food, and beverages for the general public. 2004;134(11):3100-3105. Vitamin K1 and 25(OH)D are independently and synergistically associated with a risk for hip fracture in an elderly population: A case control study. When the function has no definition, such function is known as "do-nothing" function.The "do-nothing" function is known as a pure virtual function.A pure virtual function is a function declared in the base class that has no definition relative to the base class. Jane Higdon, Ph.D. email:[emailprotected], Chlorophyll and Metallo-Chlorophyll Derivatives, Healthcare Professional Continuing Education, Vitamin K supplementation studies and osteoporosis, https://www.cdc.gov/arthritis/basics/osteoarthritis.htm, Naturally occurring forms of vitamin K include phylloquinone (vitamin K, With limited vitamin K storage capacity, the body recycles vitamin K in the vitamin K, Vitamin K deficiency may impair the activity of VKDPs and increase the risk of, Abnormal mineralization of blood vessels increases with age and is a major risk factor for, While the results of a few observational studies suggest that low vitamin K status might have a role in development of, Phylloquinone is found at high concentrations in green leafy vegetables and certain plant oils, while most menaquinones are usually found in cheese, animal products, and certain.
