Nitric oxide, the signaling molecule has been found to dilate, or expand, the veins which, in turn, promotes better blood flow.  In fact, heart patients use nitroglycerin pills placed under the tongue that cause a reaction to produce nitric oxide and relieve acute chest pain.  It therefore follows that as a preventative measure, it can be a very wise choice to find a supplement that increases the natural nitric oxide production in our bodies for healthy heart maintenance.

A known fact is that our bodies produce lower levels of nitric oxide when we are at rest and especially when we are sleeping.  Consequently, at night when we’re sleeping is a target choice as a time to encourage natural bodily production of  NO.  If you are looking for heart healthy supplements of this type, I strongly suggest you look into the work of Dr. Lou Ignarro.
