Cardiovascular disease is characterized by a buildup of cholesterol-filled plaque in the coronary arteries, which are the arteries that feed the heart. This causes them to become hard and narrow, a process referred to as atherosclerosis. Total blockage of a coronary artery produces a heart attack. High intake (7 grams daily) of dietary fiber can reduce the risk of heart disease. For this reason, heart disease supplements often contain fiber: one teaspoon of Konsyl Original Formula in the morning and one in the evening will provide 6 grams of soluble psyllium fiber.
