Senchi River Circulation Restorative contains natural nitric oxide, which is important in vasodilation, the widening of blood vessels, resulting from the relaxation of smooth muscle cells within the vessel walls, especially in the large arteries and veins and smaller arterioles. The endothelium (inner lining) of blood vessels uses nitric oxide to signal the surrounding smooth muscles to relax and expand and allow blood to reach your feet, toes, legs, and fingers. This results in the relaxing of the blood vessels and increased blood flow. Our team has created a formula that opens blood vessels and promotes increased nitric oxide production so that your blood vessels will relax and expand, allowing more oxygen-rich blood to flow to your fingers, feet, toes, and legs. Can you see how much this will help solve your blood flow and circulation problems, get those open foot wounds finally closed so that you can avoid any future foot or toe ulcers? Excellent for people who need blood flow and circulation fast, people with slow healing wounds or facing a foot or toe amputation, people on a fluid restriction, and the elderly who have a hard time swallowing pills.
