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 heart has four chambers, two upper atria, the receiving chambers, and two lower ventricles, the discharging chambers. The atria are connected to the ventricles by the atrioventricular valves and separated from the ventricles by the coronary sulcus.
