How vitamin K2 deficiency is silently clogging arteries; and what can we do to prevent it

Vitamin K2 is quietly becoming a heart health hero, though most people don't realise its importance until heart problems arise. However, Vitamin K2 continues to be the most overlooked nutrient and a deficiency in K2 has been linked to a range of cardiovascular issues, from hardened arteries to problems related to the heart valve and heart attacks, and as shocking as it may seem, it can also contribute to kidney and gallstone problems. To know how to use and incorporate K2 in our daily diet, let us dive deep into the specifics of this vitamin. Take a close look... Vitamin K2 is essential for the proper functioning of a specific protein in the human body known as Matrix Gla protein, or MGP. This important protein essentially acts as a guardian for our arteries. MGP’s primary role is to ensure that calcium is directed to our bones, its rightful destination, instead of accumulating within the blood vessels. An excess of calcium in the blood can lead to damaging consequences for the arteries and blood vessels. When there is a deficiency of Vitamin K2, MGP remains inactivated. Over time, this inactivation allows calcium to gradually accumulate in the arterial walls. Such a buildup can result in the stiffening of these arteries, which ultimately heightens the risk of developing heart-related issues should these conditions persist. Research published in PubMed Central under the title "Vitamin K2- a neglected player in cardiovascular health", states that: Increased vitamin K2 intake may reduce arterial stiffness, slow progression of vascular and valvular calcification, lower the incidence of diabetes and coronary artery disease, and decrease cardiovascular mortality. Several studies confirm that low vitamin K2 directly increases the arterial calcification process, wherein calcium, instead of going to strengthen your bones, gets misdirected into your blood vessels. One major review published inPubMed central, found that individuals with higher dietary K2 intake had up to 50% lower risk of arterial calcification and heart disease death compared to those with lower intake. These effects are so striking that people taking medications that block vitamin K, like warfarin, show accelerated arterial hardening as a side effect.This condition relates to vitamin K2's unique ability to "carboxylate"-or activate-MGP. The active form of MGP attaches to calcium, blocking its deposition in arteries. Low vitamin K2 means lots of inactive MGP, which has been consistently linked to stiffer arteries and a greater risk of cardiovascular events. Vitamin K2 is relatively uncommon in Western diets, found mostly in fermented foods (natto and some cheeses), egg yolks, and certain meats. Most modern diets are rich in vitamin K1 from leafy greens-but lacking K2, and this explains the widespread "hidden" deficiency. Recent studies show middle-aged and older adults, as well as those with chronic illnesses, are at especially high risk.Unfortunately, vitamin K2 deficiency does not have overt symptoms until serious damage has occurred. Arterial calcification is a slow and silent process, but newly recognized ways to spot the risks of vitamin K2 inadequacy include the measurement of inactive MGP in the blood.The best way to keep arteries healthy is by having adequate intake of K2, either through diet or with a high-quality supplement. While there is no set microgram per day intake of K2, typical dosages, often recommended, are from 100–200 micrograms per day of MK-7. There are no known toxicity issues, and internationally, no upper limit for vitamin K has been set.For the majority of individuals, the use of supplements presents a guaranteed and straightforward path to achieving optimal health levels. This becomes particularly critical for those who are at an elevated risk of developing cardiovascular diseases or who are already experiencing issues such as arterial calcification.Increasing intake of vitamin K2 through food or supplements can significantly lower your chances of serious cardiovascular disease, especially in older age or with other risk factors. Vitamin K2 may be just what our arteries need to stay flexible, healthy, and free of dangerous calcium buildup. K2 might just be our new, natural, science-backed solution, hidden in plain sight is the intake of vitamin K2. Incorporating adequate Vitamin K2 into your daily routine can be a simple yet powerful way to protect your heart, strengthen your bones, and support overall long-term health.
