Is vitamin K2 your body’s best buddy?

heart-with-stethoscopeThere’s been an explosion of research on vitamin K2 showing how much it affects overall health. When you look at what it says, it makes a pretty good case for why we need more of it.

Here are just three reasons vitamin K2 may be one of your body’s best friends:

1. Vitamin K2 protects your heart and arteries

There’s a bunch of studies showing vitamin K2 has benefits for cardiovascular health. Two Dutch studies, one including over 16,000 women, showed that vitamin K2 decreased risk of coronary heart disease substantially.

Another study showed that 180 micrograms of MK-7 also prevented — and even improved — age-related stiffening of arteries. A 2015 Polish study had similar findings. These studies found that vitamin K2 is essential to a key protein that inhibits arterial calcification — so we can actively protect our arteries by making sure we get enough K2. This is great news for us all!

2. Vitamin K2 benefits joints

A 2013 study shows that patients with rheumatoid arthritis who took vitamin K saw reductions in C-reactive protein, which is a marker of inflammation. And a 2015 study in osteoarthritis patients showed that those with better vitamin K status had less arthritis damage to their joints.

3. So now you’re asking, “What about bones?”

Well, of course there’s plentiful information on vitamin K2’s role in bone health already — but a couple of good new studies adds to the list. A 2015 Korean study of over 7,000 men and women showed a correlation between vitamin K2 intake and higher bone density in the spine and femur — one that was especially strong in women. This supports the findings of two earlier studies, one in 2013 and another in 2014, showing that MK-7 supplements decreased bone loss in postmenopausal women’s spine and femur.

It all adds up to one thing: Vitamin K2 isn’t just good for bones. It’s good for bodies.

P.S. As always we remind you that any form of vitamin K should not be used by those on the blood thinner known as Coumadin (Warfarin).
