Psyllium seed husk is an excellent, low caloric source of soluble dietary fiber. Consumption of seven or more grams of soluble fiber from psyllium seed husk per day from this product, in association with a diet low in saturated fats and cholesterol, may reduce the risk of coronary heart disease. Source Naturals uses only the husk of the seed, as it is a much better fiber source than the whole seed.

Because of its fiber content when mixed with water it aids in peristalsis, or rippling motion of muscles in the digestive tract to move food along the small and large intestine, reducing the amount of time fecal matter remains in the colon. This is important because if fecal matter remains too long it can create a very toxic environment increasing the risk of colon cancer.

And, due to its mucilaginous nature it acts as an adhesive grabbing onto wastes and toxins as it passes through the digestve tract, especially the colon where fecal matter tends to collect in people who eat a diet high in mucus forming foods such as flour products and milk and ice cream, eat too much animal protein, and do not take in enough fiber which is around 30 to 35 grams daily. Its ability as a mucilage also assists in carrying cholesterol and tryglycerides, known as lipids, out of the body as it dumps them into the digestive tract. If not enough fiber is taken in consistently, and bowel movements are not on a daily basis of sufficient quantity, the body will reabsorb these lipids back into the bloodstream.
