Many nutrients, such as calcium, are well recognized for the important role they play in health. But there’s one vitamin that is especially important yet often ignored in the quest for health, putting people at risk for a dangerous deficiency. Worse, this vitamin isn’t so easy to come by in our everyday diets—a scarcity that might be responsible for some of our country’s most serious health concerns.
What is this important vitamin? It’s vitamin K, but not just any form of vitamin K. One form of this vitamin is especially crucial to both bone and heart health.
There are two types of K: phylloquinone (known as vitamin K1) and menaquinone (known as vitamin K2). Leafy green vegetables are rich in the first type, which plays a critical role in your body’s clotting process. Vitamin K2, however, isn’t so easy to come by in the diet, putting many people at risk for deficiency.
K2 is essential to calcium metabolism—and without adequate levels, your body will suffer in two very different ways. On the one hand, menaquinone deficiency will cause your bones to lose vital calcium, leaving them weak and vulnerable to fractures.(1-2) But this vitamin doesn’t just keep calcium in your bones—it also keeps it out of your arteries.
Without adequate levels of K2, the chemical conversion of matrix GLA protein—an important calcification inhibitor—is blocked. As a result, calcium will build up in your arteries, causing them to harden and increasing plaque formation. (3-4)
Fortunately, population studies show that boosting levels of K2 can stop this deadly development—both lowering heart disease death rates and reducing arterial calcification among subjects with the highest intakes.(5-7) Research has shown similar benefits when it comes to bone health, with trials showing that K2 can effectively increase hip bone density in postmenopausal women.(8-10)
In an even more promising turn, researchers have tested analogs of K2 for effects on liver and prostate health.(11-15)
Unfortunately, the only abundant food source of K2 is the Japanese soybean dish called natto—as famous for its unpleasant smell and taste as it is for its profound health benefits (including lower rates of hip fractures and postmenopausal bone loss).(16-17) A much more convenient way to obtain K2 is to take it in supplement form. Ultra K2, available from VRP, provides nourishing amounts of this vitamin that’s so crucial to cardiovascular and bone health.
If you’re currently on medications such as warfarin, you’ll want to talk with your physician before taking any type of vitamin K.
