Other essential functions of vitamin K is its contribution to bone metabolism and vascular calcification inhibition. Its enzyme inhibition properties are rather weak, especially when compared with other physiological inhibitors. The vitamin is further packaged inside the enterocytes into the chylomicrons, and it then enters systemic circulation directly via the lymphatic system31 (Fig. Thijssen HH, Drittij-Reijnders MJ, Fischer MA. Triage theory proposed by McCan and Ames has suggested that, as a result of natural selection, vitamin K mainly functions for critical survival function, such as coagulation, which is protected at the expense of functions whose lack is only related with long term consequences, such as calcification or osteoporosis.

Shoemark DK, Colenso CK, Toelzer C, et al. Anything more than the recommended dose may cause toxicity like decreased appetite, enlarged liver, breathing difficulty, muscle stiffness, paleness and swelling of the body. Regardless, supplementation with natural forms of vitamin K is largely safe and hence is acceptable under specific conditions, such as in postmenopausal osteoporosis. The early years of discovery", "Packed full of questions: Who benefits from dietary supplements? [53], Deficiencies of vitamins are classified as either primary or secondary. A total of 18 men (45%) and 22 females (55%) with an average age of 28 were enrolled. [49], Each vitamin is typically used in multiple reactions, and therefore most have multiple functions. Anticoagulants and anti-platelet drugs, herbs and supplements. to the Czech Health Research Council (NU21J-0200021), and L.K.K. Serum protein induced by vitamin K absence or antagonist-II (PIVKA-II) levels were measured by electrochemiluminescence immunoassay and were expressed in milli-arbitrary units (mAUs). A protein that contains a PRO-sequence is targeted and subsequently bound to the carboxylase in the first step (A). Schaller J, Gerber S, Kmpfer U, et al. 1. Low-dose. The Authors. There was no correlation between plasma and liver levels since, surprisingly, the highest plasma levels were observed after the administration of vitamin K3 and MK-8; MK-6 reached its highest levels in the liver.50 Furthermore, vitamin K absorption can be decreased by certain drugs: cholestyramine can decrease vitamin K absorption likely due to the binding of bile acids; rifampicin can decrease vitamin K absorption due to the induction of metabolism; and orlistat forces the patient to decrease their intake of fat since it is associated with unpleasant GIT side effects.5154, Absorption and elimination of vitamin K. A: Oral absorption of vitamin K. 1: Formation of micelles from vitamin K and bile acids. [29] The following year, Frederick Hopkins postulated that some foods contained "accessory factors" in addition to proteins, carbohydrates, fats etc. In humans there are 13 vitamins: 4 fat-soluble (A, D, E, and K) and 9 water-soluble (8 B vitamins and vitamin C). The function of the Gla residues of heavy chain 2 is unknown, since 3 other characterized heavy chains (1, 3, and 4) do not contain them .145149, Proline-richGlaproteinsandtransmembraneGlaproteins: Targeted amino acid sequence research resulted in the discovery of other Gla proteins. They are widely distributed, with the highest expression of PRGP1 being in the spinal cord and of PRGP2 being in the thyroid gland.150 PRGP1 expression is limited to some tissues, whereas PRGP2 expression is more extensive.151 Further research showed that carboxylated PRGP2 is localized on the cell surface, and it was suggested that it has an intracellular binding partner YAP (Yes-associated protein).152 Later, other structurally similar members of the vitamin K protein family were discovered. [12]. [27] A similar result by Cornelius Pekelharing appeared in a Dutch medical journal in 1905, but it was not widely reported. Declaration of interest. RDA US Recommended Dietary Allowances; higher for adults than for children, and may be even higher for women who are pregnant or lactating. Adenosine triphosphate (ATP) is an example of an essential non-vitamin coenzyme. The inhibition of soft tissue calcification might be accomplished by its binding both to calcium and to bone morphogenic protein-2 (BMP-2).85,117 Solid evidence of the importance of MGP as an inhibitor of soft tissue calcification can be derived from MGP-deficient animals, which generally die within 2 months due to the calcification and subsequent rupture of the thoracic or abdominal aorta.120 Extensive arterial calcification is also observed in patients with Keutel syndrome, in which mutation of the MGP gene is present.85,121 Since the MGP can be presented as uncarboxylated-unphosphorylated, or uncarboxylated-phosphorylated and vice versa, or carboxylated-phosphorylated, it has been tested for diagnostic purposes. Several studies suggest regular consumption of this vitamin reduce the chances of liver and breast cancer. Rousseau JC, Sornay-Rendu E, Bertholon C, et al. Even though product registration is not required, these regulations mandate production and quality control standards (including testing for identity, purity and adulterations) for dietary supplements. Accessed November. [38], In 1967, George Wald, Ragnar Granit and Haldan Keffer Hartline were awarded the Nobel Prize in Physiology and Medicine "for their discoveries concerning the primary physiological and chemical visual processes in the eye." Here, it serves as an electron acceptor during photosynthesis, forming part of the electron transport chain of photosystem I. It is the key element required by the body to produce prothrombin, a clotting factor necessary for blood coagulation. Blood samples were withdrawn on days 0, 7 and 30 after the intake of MK-7 supplement. The same study, however, also reported only a tendency of vitamin K2, particularly its long chain forms, to reduce cardiovascular mortality.205 Considering the differences between the pharmacokinetic and pharmacodynamic data on vitamins K1 and K2 encompassing: the forms of vitamin K2 having longer half-lives, a more potent effect, and higher concentrations in extrahepatic tissues, a stronger effect of vitamin K2 over vitamin K1 would be expected. Schurgers LJ, Teunissen KJ, Knapen MH, et al. MyBioSource. Palermo A, Tuccinardi D, DOnofrio L, et al. In rats, the same oral dose resulted in much higher levels in the liver of vitamin K1 than of MK-4, while the opposite was found in the aorta.70 This was also confirmed in human post-mortem liver analyses, in which the amount of vitamin K1 was always higher than of MK-4.71 Surprisingly, the sum of the MK-7 to MK-11 levels in the human liver was mostly much higher than that of vitamin K1.71,72 One study found that there were no differences in the liver vitamin K1 content and MK-7 to MK-9 content between non-cancerous liver samples and hepatitis or cirrhotic liver samples; however, a clear difference in the MK-10 to MK-13 content was observed. Max Nierenstein a friend and Reader of Biochemistry at Bristol University reportedly suggested the "vitamine" name (from "vital amine"). It is now called as vitamin K. This vitamin is called an antihemorrhagic factor as it's deficiency produced uncontrolled hemoorrhages due to defect in blood coagulation. Primarily a fungus that feeds on living o..

Our study might provide evidence in eliminating the concerns of hemostatic balance for MK-7 supplementation in healthy individuals to prevent bone and vascular diseases. The individual vitamin Kdependent enzymes will be briefly characterized in Table1 and the following text. This convinced Takaki and the Japanese Navy that diet was the cause of beriberi, but they mistakenly believed that sufficient amounts of protein prevented it. coagulation activity; healthy individuals; menaquinone-7. Novel conformation-specific antibodies against matrix gamma-carboxyglutamic acid (Gla) protein: undercarboxylated matrix Gla protein as marker for vascular calcification. Another experiment showed MK-9 also to be active, but the lag time between administration and the effect was longer. Fusaro MVitamin K Italian (VIKI) Dialysis Study InvestigatorsNoale M, Viola V, et al. Vitamins are organic molecules (or a set of closely related molecules called vitamers) that are essential to an organism in small quantities for proper metabolic function. All baseline coagulation factors were found to be in the normal range. Dietary intake of menaquinone is associated with a reduced risk of coronary heart disease: the Rotterdam Study. A fatal bleeding disorder where the bloods potency of coagulation is hindered resulting in excessive bleeding during any surgery or procedure. How to cite this article: Ren R, Liu J, Cheng G, Tan J.

In comparison with other Gla proteins, it contains the highest number of -glutamic acid moieties, which span over the entire protein. The term hemostasis is derived from "hem-", which means "blood", and "-stasis", which means "to stop.". This process requires 2 enzymes [-glutamyl carboxylase (vitamin Kdependent carboxylase) and vitamin K epoxide reductase (vitamin K epoxide reductase complex subunit 1, VKORC1), which are likely located in close proximity to one another in the membrane of the endoplasmic reticulum62,7981] as well as carbon dioxide and oxygen.

At the same time, lower levels of -glutamyl carboxylase and VKOR1 were found in these samples.157, Transthyretin: There is one other Gla protein that is contrarily considered to be pathological. Swelling or pain in muscles did not occur in any individual, and no other adverse effects were observed. This enables carboxylation by -glutamyl carboxylase. [44], Vitamins are classified as either water-soluble or fat-soluble. This indicated that MK-7 administration does not alter hemostatic balance in healthy populations without anticoagulation treatment. [43], The term "vitamin" was derived from "vitamine", a compound word coined in 1912 by the biochemist Casimir Funk while working at the Lister Institute of Preventive Medicine. [67][69] A 2018 meta-analysis found no evidence that intake of vitamin D or calcium for community-dwelling elderly people reduced bone fractures. http://creativecommons.org/licenses/by-nc/4.0. Mounting evidence has shown beneficial effects of MK-7 in osteoporosis and cardiovascular disease. On the other hand, this was not found in all studies. For more information, please refer to our Privacy Policy. Arch Intern Med 2006;166:125661. Oral administration is preferred in most cases. However, it has been shown that it can interfere with anticoagulation therapy when used above 50 g/day. The activities of coagulation factors in plasma at 1:10 dilution were also measured to identify whether the activation was pronounced with MK-7. [25], In 1747, the Scottish surgeon James Lind discovered that citrus foods helped prevent scurvy, a particularly deadly disease in which collagen is not properly formed, causing poor wound healing, bleeding of the gums, severe pain, and death. The uncarboxylated prothrombin level at baseline and after 30 days of MK-7 supplementation showed no significant differences (P = .19, Fig. It has been speculated that the C4bprotein S complex can bind via its Gla domain to the surface of certain membranes and in this way regulate the complement activity.98, Heavychain2ofinter--trypsininhibitors: Two -glutamic acid carboxylated residues have also been discovered in heavy chain 2 of inter--trypsin inhibitors (gene ITIH2). The various forms principally differ in the number of 5-carbon prenyl units, which ranges from 4 to 13 (Fig. Vitamin K was discovered in 1929 as an essential nutrient for blood coagulation, which is the scientific term for blood clotting. Increased nephrocalcin has been detected in the urine of patients with renal cell carcinoma.132136, Gas6: Gas6, a product of growth arrestspecific gene 6, shares 43% homology with protein S and has the same protein organization.137,138 In contrast to protein S, plasma Gas6 levels are very low, in subnanomolar concentrations, and it is not produced by the liver.98,138 Its target is the so-called TMA, three tyrosine kinase receptors that gave name to this familyTyro3 (Sky), MerTK (c-mer), and Axl.

The term vitamin D refers to a family of compounds that are derived from cholesterol. 5), has been largely associated with its effect on bones. Cytochrome P450 3A4 (CYP3A4) substrates. Its content in these vegetables appears to vary greatly: 2501139 g/100 g and 2401220 g/100 g, respectively.12,15,20 In most cases, neither boiling nor microwaving affects the vitamin K1 content of vegetables.12 Certain vegetable oils are also important dietary sources of phylloquinone for humans. Normal form A contains 3 Gla residues, while B and C only contain 2, and D none. However, this has not been observed, possibly due to the limited sites for -carboxylation. The activated partial thromboplastin time (APTT) was measured through blood coagulation time method, and prothrombin time (PT) was determined by Quick's method. [27], In East Asia, where polished white rice was the common staple food of the middle class, beriberi resulting from lack of vitamin B1 was endemic. According to our study, the activities were proportionally decreased, showing similar trend with baseline. If one is on coumadin and wants to take natural . Osteoporos Int 2001;12:9961000. It is possible that vegetable oil offers more easily absorbable vitamin K1 than whole vegetables.48 Surprisingly, at least according to in vitro everted intestinal sac experiments, unsaturated fatty acids can decrease the extent of vitamin K1 absorption.49 There is also substantial interindividual variability in vitamin K1 absorption.45,48 Linear pharmacokinetics, ie, a linear relationship between dose and serum levels, were observed for both MK-7 and K1.23 Long-term administration of MK-7 results in a marked increase in its serum levels, in contrast to vitamin K1, for which serum levels are only slightly above placebo.23 This is because MK-7 has an elimination half-life of approximately 3 days, while that of vitamin K1 is about 12 hours.8,23 Further, MK-9 has been shown to have a long elimination half-life (about 60 hours).46 This is, however, less than that of MK-7, which suggests that prolongation of the side chain is not directly associated with increase in half-life. B: Metabolism of vitamin K in the hepatocyte. Some bacteria also produce one or more saturated prenyl units, and this is indicated by an additional suffix, eg, MK-8(2H) in Fig. The essential fatty acids that must be derived from the diet are: 4. S3 in the Supporting Information online85). Topical use of vitamin K hold high significance in removing bruises, scars, stretch marks and spider veins. Anticoagulants may be used to treat blood clots, or in conditions where the risk of blood clots is increased to reduce the risk. The seeds of some species of Apiaceae plants that are used as spices also contain significant amounts of the vitamin K1.16 Data on their vitamin K1 content differ significantly from study to study because it can be affected by a number of factors, such as cultivar, cultivation method, cultivation site, climatic conditions, plant maturation, and the method of determination.1719 The richest vegetable sources of vitamin K1, kale and spinach, are good examples of this. It need not be emphasized that the calcification of arteries is an independent risk factor for the development of coronary heart disease and coronary events.201,202 In addition, several clinical trials have reported that vitamin K antagonists promote atherosclerotic calcification.29 There has been a lot of discussion about whether there is subclinical hypovitaminosis in certain population groups. [7]. The most essential role of vitamin K is healing of wounds and reversing the harmful effects of blood thinning medicines. Cockayne S, Adamson J, Lanham-New S, et al. The mice that received only the individual constituents died, while the mice fed by milk itself developed normally. Adequate Intakes (AIs) are set when there is not sufficient information to establish EARs and RDAs. RDAs are set higher than EARs to cover people with higher than average needs. A subgroup analysis documented that the effect was observed after 10 years. This study aimed to investigate whether vitamin K2 supplementation at recommended doses affects the activity of vitamin K dependent procoagulation factors in healthy individuals without any anticoagulation treatment. It is produced in the human kidneys. This is a crucial step in bone formation the correct alignment of collagen fibers with hydroxyapatite (7). Juanola-Falgarona M, Salas-Salvado J, Martinez-Gonzalez MA, et al. Search for Similar Articles For its enzymatic activity, APC also needs protein S (PS). "Vitamin K" include several chemical compounds. This is in line with the findings from animal experiments, in which even 2 g/kg for the same period of time was safe.31 In general, the reported side effects of vitamin K have only been local, eg, minor gastrointestinal complaints and skin rashes after vitamin K2, which disappear after discontinuing administration.9,28,113,116 Clinically, intramuscular administration of vitamin K1 is not very convenient due to pain at the site of injection and skin bruising. The same is true of copper, cayenne, and bromelain. It was not present after 1 or 2 years of treatment; 3 years were needed to document its positive influence.115 Based on this information, long-term supplementation with vitamin K in postmenopausal women with osteoporosis might have some potential utility, in particular, given its negligible risk of serious side effects. Delanaye P, Krzesinski JM, Warling X, et al. The vitamin K epoxide must then be reduced again into quinone and subsequently hydroquinone by VKORC1, and the reaction continues.75,76 Through this process, vitamin K is recycled, so the physiological requirements of vitamin K are relatively low.83 Formed -carboxylated proteins are then likely transported via the classical secretory pathway through the Golgi apparatus, where the prosequence is mostly cleaved, as has been demonstrated for prothrombin by a Ca2+-dependent serine proteinase.84 There are, however, some differences: (1) matrix Gla-protein is exceptional, since the proprotein sequence is also maintained in the mature protein;85 and (2) the impact of carboxylation on secretion is different (Factor II and Factor X can be secreted both in the uncarboxylated and carboxylated forms, while proteins C and Z are secreted only in the carboxylated forms).86,87 In the case of protein C, the uncarboxylated form is decomposed by proteasome, which explains its inability to be excreted.87 Although mutated -glutamic acid carboxylated proteins can be cleft intracellularly,87 secreted -carboxyglutamated proteins cannot be reused and are excreted in urine.61 As a result, they have attracted great interest as being potentially useful for diagnostic purposes, as will be discussed later in this article. There's concern that high doses of vitamin E might affect the use of these chemotherapy drugs. [70], Europe has regulations that define limits of vitamin (and mineral) dosages for their safe use as dietary supplements. The levels of total osteocalcin vary, so the percentage of uncarboxylated osteocalcin seems to be a more suitable marker. Vitamin K is necessary for the posttranslational modification of 18 or 19 proteins, among which 11 or 12 are not related to coagulation. It should, however, be mentioned that this effect was largely driven by one single study.122 The most recent systematic review was not conclusive about the possible impact of vitamin K on calcification of major vessels.210 On the other hand, higher levels of uncarboxylated dephosphorylated MGP, as the above-mentioned marker of vitamin K deficiency, were found to be associated with higher incidence of coronary artery disease and even cardiovascular mortality.207 This was, however, not fully confirmed in another meta-analysis.122 It should also be mentioned that higher levels of uncarboxylated dephosphorylated MGP can be a consequence of administration of vitamin K antagonists and can, therefore, simply reflect that these patients are more ill.207,211,212 Hence, positive cardiovascular effects are not clearly documented for either form of vitamin K, and clinical long-term studies are definitely needed. However, the available data do not fully support this, and estrogen levels might influence it.31,163 Uncarboxylated-unphosphorylated MGP as a marker of vitamin K deficiency was mentioned above. De Roeck-Holtzhauer Y, Quere I, Claire C. Walther B, Chollet M. Menaquinones, bacteria, and foods: vitamin K2 in the diet. In particular, its involvement in connective tissue calcification has stimulated intense research, although the data are still inconclusive. [7], For the most part, vitamins are obtained from the diet, but some are acquired by other means: for example, microorganisms in the gut flora produce vitamin K and biotin; and one form of vitamin D is synthesized in skin cells when they are exposed to a certain wavelength of ultraviolet light present in sunlight. It is also used to prevent bleeding problems during overdosage caused by warfarin, salicylates, sulphonamides, other antibiotics and poisoning due to coumarins. - Cleveland Clinic Vitamin K is important for healthy bones and blood clotting. In line with these findings, exclusively breast-fed infants are more susceptible to the development of vitamin K hypovitaminosis than formula-fed children.31,165,166, Making an accurate bioanalysis of vitamin K deficiency is not an easy task. Vitamin K is an essential cofactor for the production of blood clotting factors [13,14,15]. VITAMIN K Vitamin K is the fat soluble vitamin In 1929, H Dam gave the name Coagulation vitamin from the Danish word Coagulation. S1 in the Supporting Information online). Contrarily, very high doses of vitamin K can paradoxically cause hypoprothrombinemia, as has been documented in rare human case reports.

[3]. McCann JC, Ames BN, Vitamin K. an example of triage theory: is micronutrient inadequacy linked to diseases of aging? Since newborns dont have adequate vitamin K in their bodies, they may sometimes exhibit birth defects like under developed bone, nose, fingers and face. Vitamin K derived from the German word Koagulationsvitamin is an essential fat-soluble vitamin used for blood clotting in case of cuts, abrasions or injuries. MyBioSource. Interestingly, although the natural forms of vitamin K are less active, a few clinical phase I/II studies have reported some promising data for both.213. In fact, the "K" in vitamin K is in reference to the German word "koagulation," which translates to "coagulation" or the ability to clot (or thicken) blood. There are also differences in vitamin K1 bioavailability between people with different types of diet. Periostin has been suggested to be a marker of type II immune reactions in chronic inflammatory diseases such as asthma and atopic dermatitis, as well as a predictor of the effect of biologic drugs acting on this level. If the vitamin K requirements are not met with, it may eventually lead to several chronic disorders. B: Activation of blood coagulation: in case of vascular damage, TF on subendothelial cells is now available for factor VII (FVII), which is activated. Prophylaxis with vitamin K markedly decreased the vitamin K deficiency in new-born babies due to their above-mentioned poor vitamin K stores.31,165,166 It has been suggested that preterm infants have an even greater risk of vitamin K deficiency, but there are currently insufficient data in relation to the prevention of this deficiency.189 Importantly, the effect of vitamin K administration on coagulation normalization is very rapid.166, Analyzing the 18 or 19 Gla proteins formed by presence of vitamin K, it is apparent that the effects of vitamin K are not limited to blood coagulation. It is also used in preventing bleeding disorders in the newborns exhibiting haemorrhagic disease caused due to absence of vitamin K. Vitamin K plays an integral part in promoting bone health.

Skip to content [76][79] The table Nomenclature of reclassified vitamins lists chemicals that had previously been classified as vitamins, as well as the earlier names of vitamins that later became part of the B-complex. These coenzymes can be produced from nucleotides such as adenosine, uracil, guanine, or inosine. Regardless, during bone resorption, the pH in bones decreases, which leads to osteocalcin decarboxylation and its release into the circulation.105,106 Un(der)carboxylated osteocalcin is considered by most authors to be a hormone.104,105,107,108 It has been shown, at least in animal studies, to affect glucose and lipid metabolism and to modulate fertility; it even has central nervous system effects, and could be involved in some types of cancer.104106,108 The largest data are on the cross-link between osteocalcin and insulin, and un(der)carboxylated osteocalcin has been shown to improve insulin sensitivity and glucose tolerance. It strengthens the skeletal structure, increases bone density and reduces the risk of fracture in older women. The role of osteocalcin in human glucose metabolism: marker or mediator? Many fruits and vegetables, nuts and seeds, and seed oils, Catechol nonessential; flavin reclassified, This page was last edited on 16 May 2023, at 06:27. B: Effect on bones and systemic release. The "K" is derived from the German word "koagulation". Vitamin K Functions, Food Sources, Deficiencies and Toxicity. Nutrition Practice Test Questions. The healthy individuals were given MK-7 90 g/day (vitamin K soft gel, Sungen, China), which is a subclass of vitamin K2, for 30 days. The absorption of vitamin K2, in particular long-chain MKs, is excellent and may even be complete due to the co-presence of fat, eg, in dairy products.8,9 Vitamin K1 is much less easily absorbed from the diet than dietary MK-7 or pure MK-4 are.8,45 However, pure vitamin K1 has better bioavailability than dietary vitamin K1, pure MK-4, or pure MK-9, but lower than pure MK-7.8,23,45,46 Dietary vitamin K1 is tightly bound to plant tissue, as mentioned, so pure vitamin K1 is better absorbed than the dietary form. 4: Carboxylated or 4a: uncarboxylated proprotein is transported to the Golgi apparatus, where the PRO-sequence is mostly cleaved (some proteins are also glycosylated there, not shown). User instruction. Conclusions: MK-7 supplementation at recommended dosage does not affect vitamin K-dependent coagulation factors' coagulation activity, and does not enhance the carboxylation of prothrombin in healthy individuals. [24], In 1910, the first vitamin complex was isolated by Japanese scientist Umetaro Suzuki, who succeeded in extracting a water-soluble complex of micronutrients from rice bran and named it aberic acid (later Orizanin). Tarento TDC, McClure DD, Vasiljevski E, et al. [30] When the article was translated into German, the translation failed to state that it was a newly discovered nutrient, a claim made in the original Japanese article, and hence his discovery failed to gain publicity. In fact, TMG3 is similar to PRGP1 and TMG4 to PRGP2. Vermeer C, Raes J, Van t Hoofd C, et al. The bleeding that may occur on the inside or outside of the body can be fatal. For example, there are eight vitamers of vitamin E: four tocopherols and four tocotrienols. A primary deficiency occurs when an organism does not get enough of the vitamin in its food.

Vitamin K has long been regarded as a procoagulant drug by physicians, and concerns have been raised with regard to its effects on hemostasis. This study reported that vitamin K1 decreased the incidence of coronary heart disease, but had no effect on mortality due to this disease or on the risk of stroke.39 Interestingly, the authors themselves reported that a positive impact was seen in connection with dietary patterns associated with a high phylloquinone diet. Menaquinones can also be produced by bacteria in the human body. Research Article: Clinical Trial/Experimental Study. Vitamin K is a fat-soluble vitamin originally named because it plays a part in blood clotting, or coagulation. A sensitive marker of vitamin K1 dietary depletion is the urinary concentration of Gla residues. Vitamin K1 is also called phylloquinone or menoquinone when isoprenylated. J NUTR 2004;134:31005. It should be emphasized that approximately 60% of protein S circulates with complement component C4b. [71] They may also contain levels of vitamins many times higher, and in different forms, than one may ingest through food. Vitamin K3 can redox-cycle, and this represents the major difference from the natural forms of vitamin K, which have a side chain blocking this pro-oxidation mechanism. Moreover, the net effect on the lumbar spine was questioned by the authors, since it was observed only in Asian and not in Western studies. In 2007, the US Code of Federal Regulations (CFR) Title 21, part III took effect, regulating Good Manufacturing Practices (GMPs) in the manufacturing, packaging, labeling, or holding operations for dietary supplements. prepared the toxicological section. The first meta-analysis of 17 studies showed that vitamin supplementation had a positive effect on bone mineral density in the lumbar spine, but not at the femoral neck. Contrarily, MK-4 is able to normalize blood coagulation and reverse aortic calcification.70 It should be mentioned that, in extrahepatic tissues, vitamin K epoxide reductase like 1 (VKORL1) can also be involved in vitamin K recovery; however, its importance under physiological conditions seems to be low.2,81. In 2016, overdose exposure to all formulations of vitamins and multi-vitamin/mineral formulations was reported by 63,931 individuals to the American Association of Poison Control Centers with 72% of these exposures in children under the age of five.
