Our new Swanson Ultra EndoPro™ Endothelial Support Formula features Cordiart, a pharmaceutical-grade, purified flavonoid glycoside extracted from sweet orange peels that promotes nitric oxide (NO) production by the endothelium, which in turn sends a signal to the smooth muscles to relax and support healthy circulation. Supports endothelial function.

With unprecedented potency and bioavailability and clinically demonstrated efficacy, EndoPro Endothelial Support Formula gives you a safe, effective way to promote your body's nitric oxide production and optimize endothelial function. This makes it an excellent supplement for daily cardiovascular maintenance and for promoting healthy circulation throughout the body.

Increases Energy Level and Sense of Well Being
Does seem to make a noticeable difference in my energy level and sense of well being. I only wish it were cheaper as I think I should be taking a double-dose at my weight. Because of the cost, I only take it when I know I have a lot of physical work to do.

Q: Why is the endothelium so important?
A: The endothelium is the single-cell layer that lines the interior of the entire cardiovascular system—from the heart to the smallest capillaries, making it one of the largest (in surface) organs in the human body. It uses nitric oxide (NO) to signal the smooth muscle tissues of the blood vessels to relax, dilating the vessels to facilitate blood flow.

Q: Why supplement with EndoPro™ when eNOS is already produced by the body?
A: The activity of eNOS enzymes typically declines with age, diminishing endogenous NO production and reducing the ability of blood vessels to dilate in response to changes in blood flow. Popular NO- boosting supplements such as L-arginine have limited effectiveness in such cases because eNOS activity is not sufficient to complete the L- arginine/NO conversion efficiently. Thus, maintaining endothelial function and eNOS activity is crucial for cardiovascular wellness, especially as we grow older.
