What are the health actions of vitamin K2?

Research today shows that the physiological importance of vitamin K2 increases with age, because it is opposed to many aging factors such as inflammatory phenomena, joint pain, calcification of vessels, 'Lowing bone solidity or cerebral degeneration (4 - 5 - 6 - 7).

Vitamin K2, bone solidity

Vitamin K2 therefore acts as a distributor of calcium deposits. Instead of depositing in the arteries, thanks to vitamin K2, calcium will strengthen the framework (25).

On the contrary, a low vitamin K2 intake in seniors accelerates the arrival of osteoporosis.

Everything about this product

Interaction with other Nutrimuscle products

  • For bone solidity, vitamin K2 will act in synergy with Peptide Peptid type 1 collagen (collagen peptides) and also more specific IIM type on the action of cartilages, because collagen is a major constituent of bones .

    Likewise, vitamin D considerably reinforces the effects of vitamin K2 on bone solidity (39).

    Vitamin K2 is to be taken with multivitamins which contains it vitamin K1. The K2 is therefore not duplicating with multivitamins. On the contrary, it reinforces its effects.

  • Anti-cholesterol drugs and antibiotics reduce the absorption of vitamin K2. These drugs therefore increase the need for vitamin K2.

  • The vitamins K are fat -soluble vitamins (which dilute in fat). It has long been thought that the only function of K vitamins was to act, through the liver, as a blood anticoagulant. But the liver action of the vitamins K represents only a fraction of its benefits for our health.

    understand the different vitamins k

    The vitamins of the K group are very little known, because this It is only recently that scientific research has discovered their extra liver roles essential for health. There are two main types of K1 vitamins, vitamin K1 and vitamin K2.

    despite the greatest importance for the health of K2 compared to K1, there is very little foods that bring vitamin K2. They are found in foods of animal origin (meat, egg yolk, hard cheeses ...) and in fermented products. But even, if they contain them, these are very small quantities (1). Another, tiny part is made in our intestine.

    Within the population, K vitamin deficiencies are difficult to assess, but could affect around 30% (for optimistic estimates) or even 70% of people (for pessimistic assessments) (2). << Br>
    It is children and adults over 40 years old who show the greatest deficiencies in vitamin K. Because of these increased needs, they are the ones who best meet vitamin K2 supplementation (3) .

    Likewise, people who do not eat animal foods as well as those suffering from intestinal problems like celiac disease have greater needs than average.

  • We have chosen Vitamin K2-MK7 from producer Nattopharma for its excellent patented form Menaq7 Natural.

Who is the product for?

  • Vitamin K2-MK7 Nutrimuscle is addressed:

    to athletes, so the need for K2 vitamins are more important than sedentary;
    to sedentary in addition to food for its action on longevity and on the protection of bone mass.

Research & received ideas on product

  • Vitamin K2 acts above all as a vascular protector by promoting calcium deposit in the bones (where it is useful) to the detriment of vascular depositions (where it is harmful). A vitamin K deficit produces the opposite effect by facilitating vascular deposits to the detriment of bone storage which is doubly negative for health, in particular that of the sportsman.

    if calcium is deposited and spell our arteries , it is not because of any unluckiness or because you eat too much calcium. Calcium deposits are very regulated phenomena. The main regulator is a protein called Matrix-Gla-Protein (MGP), manufactured within the cells of the vascular walls which inhibits calcifications there.

    The anti-depôt activity of this protein depends on our contribution in Vitamin K and more particularly in vitamin K2. The more the food brings vitamin K2, the more powerful the anti-deputy activity of the MGP. On the contrary, when we lack vitamin K2, the MGP is not very active and therefore not present enough to combat vascular calcium deposits.

    Effects of vitamin K2 against cardiovascular problems?

    By taking vitamin K2, calcification is reduced and therefore many cardiovascular diseases. It is largely because of this mechanism of action that vitamin K2 reduces mortality (8).

    A study carried out in 168 countries in men and women aged 15 to 64 that a low contribution in vitamin K2 (less than 5µg for 2000 calories per day) multiplies by two the risk of death by cardiovascular disease compared to people receiving 5 times more vitamin K2 (9).

    contrary, a high intake of vitamin K2 leads to a reduction in the risk of peripheral arterial diseases (10 - 11 - 12 - 13).

    correlation between kidney stones and arterial calcification?

    Medical studies Statistics show that persons with kidney stones have risks of arterial calcification above average (14).

    K1 vitamin vitamins as well as vitamin K2) can help them fight both against these calculations and against calcification (15 - 16).

  • Vitamin K2 Second insulin in its effects, especially at the muscle level, to maintain normal blood sugar on the short and long term (28).

    This explains that people diabetics have lower levels of vitamin K2 than others. In addition to poor diet, studies reveal that their intestinal capacities to synthesize vitamin K2 are abnormally weak (29).

    This double phenomenon explains why research shows that vitamin K2 has many benefits in diabetics (30 - 31).

    1. Vitamin K contributes to bone health.

    2.The vitamin MK7 contributes to the maintenance of the elastic properties of the arteries.
