Endothelial Progenitor Cells (EPCs) are a special type of stem cell that circulate in your body and aid in the formation of new blood vessel growth, repair the inner lining of your blood vessels, and break up plaque formation within the arteries. Low levels of these cells have a host of detrimental effects on the body associated with chronic and degenerative disease, and stimulating the release of these cells may aid in overall health and well-being.
