This one simple nutrient can STOP heart failure

Every day's a little shorter now, and that can mean only one thing: It's harder than ever to get your vitamin D!

Most folks don't get what they need even at high noon in summer, simply because they don't go outside or (wisely) cover up when they do.

But it's an even bigger struggle to generate D in autumn. If you go outside, the shorter days and changing angle of the Earth combined make it tougher for your body to generate the vitamin, even in ideal circumstances.

It's time to fix that -- and fast -- as new research shows just what's on the line.

The stakes are a whole lot bigger than you might think, as the study finds that low D can lead directly to heart failure.

That's a condition so deadly every day can feel like borrowed time. Half of all the folks who develop the condition are dead within five years, and the sad reality is that many die a whole lot sooner.

One way to avoid it? Boost your D, because the new study finds low intake will dramatically increase your risk of heart failure.

When I say"dramatically," I'm not exaggerating.

Normally, we talk about factors that can increase your risk of something by 20 percent, 30 percent, or 50 percent. Maybe some really bad risk factors will double or triple your odds.

Those are big numbers, but they're not even close to what we're talking about here.

The new study of older folks finds low D will increase your risk of heart failure by more than 1,200 percent!

The study was an analysis of medical records, not a clinical trial, so it doesn't show why D can play such a big role in heart failure.

But there's a basic biological reason for it.

Earlier studies have found that vitamin D can increase what's known as ejection fraction, or the amount of blood pumped out of the heart with every beat.

The lower the ejection fraction, the more risk you face. And if it sinks too low, you've got heart failure.

Get the D you need as part of a healthy lifestyle, and you just might be able to prevent your ejection fraction from dipping into that danger zone.

D is also essential to bone health, immune function, cancer protection, and more -- so, make sure you're getting plenty of it all year long.

The best and most consistent way is with a D3 supplement. Most folks should take between 2,000 and 5,000 IU per day, but your needs will depend on your own risk factors, so speak to your doctor.
