There’s a one-cell-thick lining inside your blood vessels—and most people have never heard of it.
It’s called the endothelium. It senses what’s happening in your bloodstream and tells your vessels whether to relax or constrict. A healthy endothelium produces nitric oxide and keeps your vascular system in balance.
