Slash your risk of death with this safe and natural supplement

There are plenty of nutrients that fight disease -- but you won't find too many that can take on death itself and win.

But omega-3 fatty acid in fish oil can do just that, and do it so well it could literally add years to your life -- 2.2 years, to be exact, according to a new study from Harvard and the University of Washington.

It's not just a lower risk of one disease or another. The study of 2,700 American seniors tracked for up to 16 years finds that people with the highest blood levels of the omega-3 fatty acids found in fish oil have a 27 percent lower risk of death from all causes.

And if you think that's impressive, you should see how well fish oil protects your heart -- because high blood levels of omega-3 fatty acid may be able to slash your risk of death from heart disease by 35 percent and death from arrhythmia by 45 percent.

Believe it or not, I'm still not done.

One omega-3 fatty acid, DHA, could cut your risk of death from coronary heart disease by 40 percent and CHD death due to arrhythmia by 45 percent. In addition, the omega-3 fatty acid DPA may slash your risk of stroke, while EPA could cut your risk of nonfatal heart attacks.

Of course, the study in the Annals of Internal Medicine may be new -- but the results aren't.

We've seen numbers like these before, and you can bet we'll see them again, because omega-3 fatty acids are proven to help the heart in a number of very specific ways. They can improve blood pressure, lower levels of deadly triglycerides, and help keep your heart rate steady -- and that last benefit has been proven again by another new study.

This one, an analysis of 15 clinical trials, finds that fish oil supplements can literally help keep your heart beating at a steady rate.

If those were the only benefits of omega-3 fatty acids, I'd recommend supplements to absolutely everyone -- men, women, children and even pets.

But that's only the beginning of a very long list of benefits.

Omega-3 fatty acids can support the immune system, reduce inflammation, fight depression, and more. They can even protect the brain in general and help to preserve memory in particular.

In one new placebo-controlled study of young and middle-aged adults, daily supplements of fish oil boosted episodic memory in women and improved the reaction times of working memory in men by 20 percent.

But you don't have to be young or middle-aged to get the brain boost that comes from regular fish oil supplementation. Omega-3 fatty acids have shown to help improve mood, memory, and overall cognition in older adults and seniors.

They may even turn out to be one of the most important weapons we have in the fight against dementia.

A steady fish habit used to be the best way to arm yourself with this powerful weapon. But these days, too many fish are packed with dangerously high levels of mercury.

To learn which are safe and which you should never let pass your lips, read this.

For now, however, the safest and most reliable way to get the omega-3 fatty acids you need for all these benefits and more is with a quality fish oil supplement.
