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.
Chambers of the Heart. The heart is composed of four well separated chambers. The two superior chambers are the atria (= entry halls) , and the two inferior chambers are the ventricles (= little bellies). The atria are the receiving chambers, they receive venous blood from systemic and pulmonary circulation and pump it down into the ventricles. The ventricles are the distributing chambers, they pump blood out of the heart into the peripheral circulation.
