http://www.naturemade.com/heartHealth/ A CoQ10 supplement provides energy to your cells, and the CoQ10 antioxidant properties help protect your heart from free radicals.

This is CoQ10.
CoQ10 is responsible for creating 95% of the human body's energy.
How does it start? CoQ10 helps deliver the spark...
...to a part of our cells called mitochondria—that's the part that gives our cells energy.
And once energized, this is the part of our cells that sustain life.
When your heart has more energy, it works better.
CoQ10 is also a potent antioxidant...
...that helps protect your heart against damage from free radicals.
When it comes to strengthening your heart muscle, CoQ10 has a lot to offer.
