Due to the nattokinase ingredient, the suggested dose is one capsule three times daily. If you have a condition in which you would like to take a higher dosage than 1 cap, three times daily (for example, fibroids or scar tissue) regular Vitalzym would be the better choice because you can take it in higher doses.
The upper chamber is called an atrium (or auricle), and the lower chamber is called a ventricle. The two atria act as receiving chambers for blood entering the heart; the more muscular ventricles pump the blood out of the heart.
Accordingly, first the upper chamber of the heart is stimulated to contract and send blood into the lower chambers (ventricles) of the heart. There is a slight delay in the electrical signal that allows the ventricles to fill. Then the ventricles contract pumping blood throughout the body. Another slight delay then occurs, allowing blood to return to the upper chambers of the heart, refilling the heart for the next cycle.
