Vitamin K2: the key nutrient of health
In recent years we have found increasingly scientific evidence of the benefits of vitamin D. Although we knew well, we had not yet aware of how their benefits are extraordinary to the point of turning it into the most important vitamin of the decade.
But now is begining to emerge evidence that other vitamin has received the lights of the research as the nutrients lost in combat from osteoporosis to heart disease. This important nutrient is vitamin K2, which has been considered a potentiator of vitamin D very important when used in combination. Many studies have focused on the interaction between vitamin K2, and vitamin D3, especially in terms of strengthening bone and cardiovascular health.
According to Dr. Cees Vermeer, a leading researcher in vitamin K, nearly all people are deficient in this vitamin, as well as vitamin D.
Vitamin K2 absorbed in foods may even be sufficient to maintain adequate blood clotting, but it is not enough to ensure the protection against:
lung, prostate and liver cancer;
dementia and other brain problems;
and many others.
Combining vitamin D and vitamin K
It is no novelty that vitamin D plays an important role in calcium absorption promoting a significant improvement in bone. However, new evidence indicates that it is vitamin K2 who directs the calcium to be absorbed by the skeleton, avoiding that calcium is deposited in inappropriate places such as the joints (arthritis), in the arteries (atherosclerosis) and organs (vesicular calculation , kidney stones, cataracts).
Vitamin K2 activates a protein called osteocalcin produced by osteoblasts, which in turn is required for calcium uptake in the bone matrix. Osteocalcin also prevents calcium to be deposited in the arteries.
It is evident the importance of vitamin K2 for our body, because without it the action of vitamin D can cause calcium deposits in the arteries instead of penetrating the bone.
Forms of vitamin K
There are two types for vitamin K: vitamins K1 and K2.
1) Vitamin K1: Found in vegetables, goes straight to the liver and helps in maintaining healthy blood clotting.
2) Vitamin K2: It is produced by bacteria and is present in large quantities in their digestive tract but is not absorbed by it with ease. Vitamin K2 goes straight to the wall of blood vessels, bones and other tissues except the liver.
In turn, vitamin K2 also shows some variations: MK 4, MK 7, MK 8 and MK 9. More importantly for our case is MK 7, a form with then most practical applications.
The desirable form of vitamin K2 is MK7.
MK 7 is extracted from a product derived from fermented soybeans called natto. You can get significant amounts of vitamin K2 consuming natto, however, few people tolerate the smell or texture preferring to use in supplement form. The consumption of fermented cheese is also a good source of vitamin K2.
When your body is attacked or injured, it responds by an inflammatory reaction caused by the deposit of calcium in the damaged tissue. When this occurs in your blood vessel, it means that you are having noticeable manifestations of coronary artery disease, or plaque formation in the artery that might cause a heart attack.
Vitamin D and vitamin K2 act together to increase the matrix GLA protein (MGP or). This is the protein responsible for protecting your blood vessels from calcification.
The GLA matrix is so important that it can be used as a reference cardiac and vascular condition by laboratory measurement. And scientific studies confirm that the intake of increased vitamin K2 reduces your risk of coronary heart disease.
See other important data:
In 2004, the Rotterdam study was the first to demonstrate the effect of vitamin K2 in extending survival of individuals. People who had a high intake of vitamin K2 were 50% lower risk of death from coronary heart disease and less calcification of the arteries than those who had low intake of this vitamin.
In a subsequent study of 16 thousand people followed for 10 years, the researchers found that each additional 10 mcg of vitamin K2 represented a significant 9% reduction in cardiac events.
Animal studies have shown that vitamin K2 not only prevents hardening of the arteries, but can also reverse calcification of arteries highly calcified by activation of MGP.
People with severe calcifications were high percentage of inactive osteocalcin, indicating a general deficiency of vitamin K2.
would not be then that calcium supplementation is increasing your risk of heart attack?
If you are making use of calcium and vitamin D supplements, but is deficient in vitamin K2, you may be making things worse, according to a recent meta-analysis linking calcium to heart attacks.
In this study it was observed that individuals were ingesting calcium supplement were more likely to have heart attack. But it is important to note that this does not mean that calcium is the cause of this situation.
In this meta-analysis it has been observed that individuals who only ingested calcium when they were compared to others that ingested additional calcium magnesium, vitamin D and vitamin K2, could have adverse effects such as the formation of atherosclerotic plaques in coronary arteries causing heart attacks.
So if you'll take calcium, you should balance it with vitamin D and vitamin K2. Also, do not forget to also supplement magnesium, silica, Omega 3 and do resistance exercises.
Countries with higher calcium intake ratio, for example, the United States, Canada and Scandinavia, have the highest incidence of osteoporosis. This is the so-called paradox of calcium.
This is because it consumes calcium in a wrong way without taking into account the need of vitamin K2, which is responsible, as we saw earlier, by directing calcium to the correct places. If not, this calcium ends up in the arteries, kidneys, bladder, joints or eyes, causing problems like atherosclerosis, stones, arthritis and cataracts.
