We have recently reviewed the intrinsic need for vitamin K2-7 supplementation in peripheral neuropathy ( Vaidya et al. It is a potential autologous growth stimulator for HCC proliferation and has insufficient coagulant activity. In addition, the effect of globular adiponectin is controlled by adiponectin receptor 1 resulting in increased phosphorylation of PPAR-α, p38 MAPK and AMPK.

The study reported that MK-7 supplementation as low as 10 µg should be avoided during VKA as it can significantly affect the anticoagulation sensitivity in few individuals ( Theuwissen et al. In glycerol dissimilation pathway, overexpression of enzymes like glycerol kinase (GlpK) and glycerol-3-phosphate dehydrogenase (GlpD) led to conversion of glycerol to dihydroxyacetone phosphate (DHAP). It is known that dp-ucMGP increases in vitamin K-deficient patients which can be associated with vascular calcification.

The newly synthesized osteocalcin is inactive and it requires vitamin K2-7 for converting itself into active form by carboxylation, and later bind to calcium ( Hauschka et al. This indicated that during vitamin K2-induced growth inhibition in HCC cells, the expressions of cyclin D1 and Cdk inhibitors is regulated. NATTO DERIVED: Formed by Soybean fermentation, the production of superfood Natto produces the same MK7 as formed by your own stomach’s microflora. The effect of MK-7 supplementation on the activity of vitamin K-dependent procoagulant factors was investigated by Ren et al.

Vitamin K2-7 is a cofactor of enzyme γ-carboxylase, that converts glutamic acid (Glu) residues present in the molecule of osteocalcin (OC) to γ-carboxyglutamate (Gla) and is, therefore, necessary for the γ-carboxylation of OC. MK-7 (1500 mg/L) in an oil solution form was mixed with vitamin K1 resulting in a mixture containing 100 µg/ml of vitamin K1 and K2 (MK-7) each. Menaquinone (also referred to as MK-n) differs in the length of its side chain varying from 4 to 15 isoprene units; n denotes the number of isoprene units present in the structure ( Beulens et al.

Excretion of K2-7 involves shortening of isoprenoid side chains to form metabolites of carboxylic acid with 5-carbon side chains. In addition, vitamin K2 facilitates the activation of Gas6 by carboxylating the Gla residues of Gas6, which is structurally related to anticoagulation factor protein S. The serum samples collected after 6 and 12 months showed decrease in the ratio of ucOC to cOC; however, it was not significant ( Ozdemir et al. Interestingly, the ratio of circulating K2-7 serum levels between eastern Japanese women and British women is 15:1 which inversely mirrors the fracture rate of 1 in Japanese women to that of 15 in British women ( Kaneki et al. Vitamin K2 is also worth supplementing along with vitamin D3, to increase the proper effect of this vitamin.

Furthermore, Vitamin D plays a role in gut health; it nourishes the microbiome, boosting immunity and diversity. determined the synergistic effect of sorafenib and vitamin K2 on human hepatocellular carcinoma (HepG2) cells. AroG D146N and PyrG E156K are overexpressed in shikimate (SA) pathway and pyrimidine metabolism pathway respectively to lead the components of both the pathways towards MK-7 pathway and form MK-7 as the end product (Adapted from ( Yang et al. The yogurt Kplus group was observed to have the highest plasma concentration during the initial 14 days of the treatment (2. Menaquinone-7 as a Novel Pharmacological Therapy in the Treatment of Rheumatoid Arthritis: A Clinical Study.Sixty-eight patients were randomly administered either with 360 μg daily of MK-7 or placebo for 6 months. As nuclear binding receptor for vitamin K2-7 is present on MC3T3E1 cells, it is possible that, through production of BMP2, K2-7 has an indirect effect on the BMP2-Smad1 pathway. The plasma levels of dephospho-uncarboxylated matrix Gla protein (dp-ucMGP) was decreased to 485 ± 30 pmol/L in the yogurt Kplus group, 417 ± 33 pmol/L in the yogurt K group and 434 ± 31 pmol/L in the capsules group. After 6 weeks of treatment, the plasma levels of the hemodialysis patients were assessed which indicated the level of dp-ucMGP and ucOC was 4. The post-translational carboxylation of the prothrombin precursor is dependent on vitamin K-dependent γ-glutamyl carboxylase.

Taken together, the health-beneficial effects of K2-7 in various diseases underscore the need for supplementation of K2-7 in the global diet as evidenced by clinical and molecular data. It was also observed that all the formulations gave similar 24 h absorption profiles which indicated that the vehicle carrier does not affect the absorption of MK-7 ( Mhj, 2014). gov/ct2/show/ {"type":"clinical-trial","attrs":{"text":"NCT04477811","term_id":"NCT04477811"}}NCT04477811 (Accessed October 7, 2021). Activation of NF-κB is essential for osteoclasts proliferation which results in osteoporosis through bone resorption. ng/ml), while the plasma concentrations of yogurt K and capsules group in the same period were reported to be 2.Blood samples were collected for measurement of MK-7 as well as serum concentrations of cOC and ucOC. In MG6 cells derived from mouse microglia exposed to lipopolysaccharide, different concentrations of vitamin K2 (0–10 µM) were used; wherein the upregulation of inflammatory cytokines like IL-1β, IL-6 and TNF-α were highly suppressed at 10 μM at mRNA level. We also review the evidence for the health-beneficial outcomes of K2-7 in diabetes, peripheral neuropathy and Alzheimer’s disease. This underscores the lack of adequately-designed intervention trials for K2-7 that can truly capture the real-world evidence-based scenario in clinical therapeutics.
