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.
The mitral and tricuspid valves are located at the bottom of these chambers. As the blood builds up in the upper chambers, these valves open to allow blood to flow into the lower chambers of your heart. After a brief delay, as the lower chambers begin to contract, the mitral and tricuspid valves shut tightly.
