A protein called MGP (matrix Gla protein) is key for preventing the unwanted buildup of calcium in your arteries and requires vitamin K2 to function. Researchers have discovered that healthy arterial tissues contain up to 100 times more vitamin K2 than calcified arteries, Restoring blood levels of vitamin K2 can potentially help reverse the buildup of calcium caused by a vitamin K2 deficiency.

Vitamin k supplementation promoted the reduction in urinary calcium excretion and stimulated intestinal calcium absorption in rats on a normal calcium diet. I follow the recommendation of a nutrologist, allied to vitamin d3 supplementation and use it in a preventive way!

Background observational and some experimental data suggest that low intake of vitamin k may be associated with an increased risk of fracture. The extra carboxyl group in gla made clear that vitamin k plays a role in a carboxylation reaction during which glu is converted into gla. Several observational studies have suggested that vitamin k2 is better than k1 at reducing these calcium deposits and lowering your risk of heart disease (18, 19, 20).

More research on the stimulating role of vitamin d on vitamin k-dependent proteins is urgently needed to study the underlying mechanisms. Sufficient quantities of vitamin k in the body are necessary for the activation of these proteins in the body to take place, which then allows the proteins to bind calcium, and to move it around, and to function as an essential regulator of calcium and magnesium metabolism within the body, and specifically in bones, the heart, the arteries, the kidneys, teeth, etc. Simplified overview of potential synergy between vitamins d and k and bone and cardiovascular health. Vitamin k 2 includes a range of vitamin k forms collectively referred to as menaquinones. Malabsorption of fat and fat-soluble vitamins (A, d, e, k) may occur and can cause subclinical deficiencies of some of these vitamins. They both are co-factors for an enzyme that catalyzes the carboxylation of glutamic acid residues on vitamin k-dependent proteins. The body will mainly use vitamin k1, which is much more abundant in our food. Safely dosing vitamin e has always been a challenge until this puzzle piece was revealed to me. Several hormones and growth factors, including vitamin d but not vitamin k, regulate osteocalcin synthesis by osteoblasts.

Role of vitamin k2 in the development of hepatocellular carcinoma in women with viral cirrhosis of the liver. One 10-year population study, the rotterdam study, did show a clear and significant inverse relationship between the highest intake levels of menaquinone (Mainly mk-4 from eggs and meat, and mk-8 and mk-9 from cheese) and cardiovascular disease and all-cause mortality in older men and women. I highly recommend it to all those who need a boost on k-2 vitamin (Specially if they do not have much fermented food that would provide it to the body). 1 A few years later, american biochemist edward adelbert doisy determined the chemical structure of vitamin k and succeeded in synthesising it.

Commenting on the potential mechanisms of action for improving insulin sensitivity and glucose tolerance, the authors noted several possibilities including carboxylation of vitamin k-dependent protein, regulation of adipokine levels, anti-inflammatory activity, and lipid lowering effects. Further investigations are necessary to examine the role of other vitamin k-dependent proteins (E.

Although circulating dp-ucmgp was correlated to various markers of vitamin k status, no association with measures of coronary artery calcification were found. They concluded that mk4 supplementation at 600 ug/day or more was important in terms of the vitamin k requirements for bone health.
