Take 1 Nutrimuscle vitamin K2-MK7 capsule per day.
Special features of Nutrimuscle vitamin K2
A significant characteristic of Nutrimuscle's vitamin K2 compared to others is that it is not a low-cost Chinese generic product, but a patented vitamin K2, which has therefore been much more carefully analysed and used in numerous scientific studies. Moreover, it's made in Europe.
Why choose MK-7 vitamin K2?
There are several variants of vitamin K2 available. But there are numerous reasons to opt for vitamin K2 MK-7. Compared to other K vitamins, K2 MK-7 has a better bioavailability (it is much better absorbed than the others) and has a longer half-life (it stays longer in the body, so it has more time to work compared to other rather fleeting K2 vitamins, because they are quickly eliminated (32 - 33 - 34)).
What are the health benefits of vitamin K2?
Research today shows that the need for vitamin K2 increases as we get older, as it counteracts many of the factors of ageing such as inflammatory issues, joint pain, calcification of the vessels, diminished bone strength, and cerebral deterioration (4 - 5 - 6 - 7).
Vitamin K2: bone strength
Vitamin K2 acts as a distributor of calcium deposits. Thanks to vitamin K2, instead of settling in the arteries, calcium can reach the bones and strengthen them (25). On the contrary, a low vitamin K2 intake in senior citizens accelerates the onset of osteoporosis.
Vitamin K2 and longevity
A Spanish study conducted over 5 years with more than 7000 people also showed that the higher a person's vitamin K2 intake, the lower their risk of cancer and mortality (26). Beyond the effects on cardiovascular and bone diseases, a high vitamin K2 intake is associated with a lower risk of metabolic disease (27).
1. Vitamin K contributes to bone health.
2. Vitamin MK7 helps maintain the elastic properties of the arteries.
Although they have always been present and their importance to health has always existed, doctors are not yet able to set an official threshold for minimum intake of K1 and K2 as they do for other vitamins.
Studies, both short term and long term, do not detect any side effects to the intake of vitamin K2, even at high doses (35 - 36 - 37 - 38).
It seems prudent to us, for athletes not receiving drug treatment based on anticoagulants, to regularly use a vitamin K cocktail comprising both vitamin K1 and especially K2.
The need for vitamin K supplementation is even greater in endurance athletes prone to demineralization (swimmers, cyclists, marathon runners ...).

In the morning with breakfast is best.
Since vitamins take effect in the long term, it is preferable to do the following:
follow prolonged treatment plans
that span the duration of your intense training.
Short treatments of just a few weeks are not really appropriate.
Synergies between supplements
As collagen is a major constituent of our bones, vitamin K2 acts in synergy with Peptan Collagen Peptide (type-1 as well as type-IIm, which has a more targeted effect on cartilage) to promote bone strength.
Similarly, vitamin D significantly enhances the effects of vitamin K2 on bone strength (39).
Vitamin K2 is to be taken with multivitamins, which contain vitamin K1. K2 therefore does not simply duplicate the effect of our multivitamins. On the contrary, it reinforces it.
Adverse reactions between supplements
Anti-cholesterol drugs and antibiotics reduce vitamin K2 absorption. These drugs therefore increase your need for vitamin K2.

K vitamins are fat-soluble (diluted in fat). It was long thought that the only function of vitamin K was to act, via the liver, as a blood anticoagulant. But the hepatic effect of vitamin K is only represents a fraction of its benefits to our health.
Understanding the different K vitamins
Little is known about K group vitamins, as it is only fairly recently that scientific research uncovered their super-hepatic roles, which are essential for our health. There are two main types of vitamin K: vitamin K1 and vitamin K2.
Despite the greater importance of K2 compared to K1 when it comes to our health, there are very few foods that provide vitamin K2. It is found in animal products (meat, egg yolks, hard cheeses, etc.) and in fermented products. But though they are indeed present, they areis is in very small quantities (1). Another tiny amount is made in our intestines.
The vitamin K deficiency level of the general population is difficult to assess, but it could affect about 30% (if we're being generous) or even 70% of people (as a worst-case scenario; 2).
Adults over 40 and children have the greatest vitamin K deficiencies. Because of these increased requirements, they are the most responsive to vitamin K2 supplementation (3).
Similarly, vegans, as well as those with intestinal problems such as coeliac disease, have higher than average needs.
Vitamin K2 acts first and foremost as a vascular protector by promoting the deposition of calcium in the bones (where it is useful), while inhibiting it in the blood vessels (where it is harmful). A vitamin K deficiency produces the opposite effect by facilitating vascular deposits, to the detriment of bone deposits, which is doubly negative for our health, especially for athletes.
When calcium deposits clog our arteries, it is not down to bad luck or because we've consumed too much. Calcium deposits are highly regulated phenomena. The main regulator is a protein called matrix-gla-protein (MGP), which is produced within the cells of the vascular walls and inhibits calcification.
The deposit-inhibiting effect of this protein depends on your vitamin K (and more importantly vitamin K2) intake. The more vitamin K2 there is in your diet, the more powerful the MGP ant-deposit effect is. On the other hand, when vitamin K2 is lacking, MGP is not very active, and therefore not available enough to fight against vascular calcium deposits.
Does vitamin K2 combat cardiovascular problems?
Taking vitamin K2 reduces calcification and therefore many cardiovascular diseases. It is largely due to this effect that vitamin K2 reduces mortality (8).
A study carried out in 168 countries including men and women aged 15-64 shows that a low vitamin K2 intake (less than 5µg per 2000 calories per day) doubles the risk of death from cardiovascular disease compared to people consuming 5 times more vitamin K2 (9).
On the contrary, a high intake of vitamin K2 leads to a reduced risk of peripheral artery disease (10 - 11 - 12 - 13).
Is there a correlation between kidney stones and artery calcification?
Statistical medical studies show that people with kidney stones have an above-average risk of artery calcification (14).
Vitamin K (vitamin K1 as well as vitamin K2) can help them fight both these stones and calcification (15 - 16).
Is sport good for health, especially heart?
A popular belief says that sport is good for your health! If it is true that the repetition of moderate physical efforts promotes cardiovascular health, as soon as you push the machine, and that, whatever the sport, the effects on the heart will no longer be of a single order: it there will be some good, but also some bad (17).
Thus, much greater calcifications are found in good level marathoners than in sedentary people of the same age (18).
A 25-year follow-up of people practicing endurance sports shows that the most assiduous athletes are also those who have the arteries most clogged with calcium (19).
These results, which might seem paradoxical, have been confirmed by several other studies (20 - 21).
Strength training, arterial stiffness and calcification
Unlike moderate endurance work which tends to reduce arterial stiffness, weight training and more generally strength training tend to increase arterial stiffness over the long term. This is normal, because the heavier you train, the more sudden a rise in tension (22 - 23).
In order to prevent "surges" from causing bleeding, the arterial walls strengthen instead of remaining thin and fragile. In exchange for this solidification, they lose their flexibility. This long-term reaction is not necessarily pathological, as it is a normal physiological response. On the other hand, if calcification is added to this over-rigidity, the cocktail risks becoming explosive and can easily lead to heart problems (24).
In this context, bodybuilding or even intense endurance work, continuous vitamin K2 supplementation takes on its full meaning.
Vitamin K2 supports insulin in its effects, especially at the muscle level, for the maintenance of normal blood sugar levels in the short and long term (28).
This explains why people with diabetes have lower vitamin K2 levels than others. Besides a poor diet, studies show that their intestinal capacity to synthesize vitamin K2 is abnormally low (29).
This double phenomenon explains why research shows that vitamin K2 has many benefits in diabetics (30 - 31).
We have chosen vitamin K2-MK7 from producer Nattopharma for its patented excellent quality form MenaQ7 Natural.
