Friend, the idea of taking a “brain vitamin” may sound too good to be true…

But SHORING UP our cognitive health as we get older could be as simple as making sure our levels of one vitamin in particular don’t dip too low.

The mainstream says that a deficiency in this vitamin is UNCOMMON…

But there are certain key reasons why it’s MORE common in older folks!

Here’s the vitamin that should NEVER be overlooked when it comes to cognitive health…

And even more importantly, here’s how to make sure you’re getting the RIGHT version of it!

You’ve likely already heard how vitamin K helps boost your heart health.

In fact, it’s best known for helping your blood clot properly… so you don’t experience excessive bleeding.

Problem is, older folks are in the crosshairs for becoming DEFICIENT in this vital vitamin…

Either because of inadequate nutrition…

Impaired ability to absorb fat (like from gallbladder issues or removal, since K is a fat-soluble vitamin)…

Or even taking certain medications!

That’s right – taking drugs like antibiotics and even blood thinners (like warfarin) could INTERFERE with vitamin K levels.

And according to the latest research, low vitamin K in older folks has been linked to cognitive decline.

In the study out of Japan published earlier this year, subjects with an average age of 75 were tested for biomarkers of low vitamin K status and evaluated on their cognitive performance.

Those with the most DRAMATIC measures of K deficiency were 65% more likely to demonstrate cognitive impairments…

Specifically, in categories dealing with language… simple math… and orientation to time and place.

These findings go hand-in-hand with a 2019 meta-analysis, which found that vitamin K could help beat back Alzheimer’s disease.

And previous research has also found that older folks with low K were 2X more likely to develop DISABILITY than those who get enough of the vitamin.

This gets worse…

Because a 2020 study found that subjects with the LOWEST vitamin K levels had a 19% higher risk of premature death from any cause.

Unfortunately, too many folks don’t realize that there are 2 different but related versions of vitamin K.

Vitamin K1 is what you find in spinach and other dark leafy greens. But it’s vitamin K2 that’s associated with cognitive benefits, as reflected in this latest meta-analysis.

You can get K2 by eating meat and dairy (like cheese)… or fermented foods…

But it’s hard to know exactly how much you’re getting… or whether it’s enough.

You might think you’re all set if vitamin K2 is included in your multivitamin…

But even if it is, it might be a PALTRY dose!

Consider taking a supplement – especially one that combines K2 with vitamin D3.

These two hero vitamins work together in MANY ways, helping MAXIMIZE each other’s potential.

And in separate studies, vitamin D supplementation has been shown to benefit Alzheimer’s and other types of dementia.

As I mentioned earlier, vitamin K only dissolves in fat…

So, you’ll want to take your capsules with food… or add a little healthy oil to those greens.
