2 Supplements Keep Your Arteries Smooth and Flexible

You probably already know that heart disease is the number one killer. One major cause of heart disease is arterial elasticity.

What is arterial elasticity? When arteries are healthy, they bend and stretch easily. They’re smooth and flexible. But as we get older our arteries get harder and lose this elasticity.

This is not good because arteries need to be elastic and flexible to efficiently deliver blood. When they become stiffer, your blood pressure goes up and your circulation decreases. It’s harder for blood to move through them.

But that’s not all you need. The endothelium is the inner lining of arteries. In the small arteries closest to the cells, the endothelium determines blood flow. As endothelial function decreases, it deprives the cells of blood.

Both arterial elasticity and endothelial function are critical for healthy circulation. Both get worse as we get older. And both are impaired in heart disease. But a new study says a two-nutrient combination can make a big difference.

The researchers in this study rounded up 65 healthy Los Angeles County firefighters. They picked on firefighters because of the strong connection between stressful jobs and heart disease. First, they measured the arterial stiffness and endothelial function in each of the firefighters.

Then they gave half of the group four tablets of aged garlic extract (300 mg/tablet) plus 30 mg of CoQ10 every day. The other half received a placebo. One year later, they remeasured the arterial stiffness and endothelial function.

They found that “The combination of aged garlic extract and CoQ10 was independently associated with significant beneficial effects on arterial elasticity and endothelial function in firefighters with high occupational stress.”

So if you have high blood pressure, are in a high-stress job, have heart disease, or for some other reason are at risk for heart disease, you should take note of this study. And don’t forget that both of these supplements significantly reduce blood pressure.

The best brand of aged garlic extract is Kyolic. You can get it online. And the best form of CoQ10 is Ubiquinol, which is the most easily absorbed form.
