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 is a two stage electrical pump. The upper chambers of the heart, the atria, (single= atrium) collect blood from the body and pump it into the lower chambers, or ventricles. There is a little delay for the ventricles to fill, and then they pump the blood out of the heart and back to the body.
