As a person ages, medical conditions such as high blood pressure, high cholesterol, diabetes, or weight gain, can cause damage to the arteries, including the arteries in the legs. Plaque build-up and thickening blood vessel walls can restrict the flow of blood through the arteries.
As blood vessels narrow, oxygen-rich blood to the muscles and tissues is reduced, causing pain, cramp, tiredness, weakness, and a “heavy” feeling. In clinical trials of the Circulation Booster by Revitive, oxygen-rich blood flow was shown to increase to both the legs and feet during use.
Also, legs and feet are more likely to have issues with circulation because they are the areas of the body furthest from the heart. Blood has farther to go when leaving the heart, and requires more work to fight gravity on its way back.
Leg veins lead back to the lungs as well, and are therefore very important to overall circulation. But they do not have a pumping action of their own. For good circulation to occur, the legs and feet rely on movements - such as walking - to keep the blood flowing and returning to the heart.
The Circulation Booster by Revitive can also play a role. It has been clinically proven to significantly increase the flow of venous blood back to the heart during use.
