Psyllium fiber comes from the outer coating, or "husk" of the psyllium plant's seeds. It is not wheat, and is therefore gluten free.
The psyllium husk is a natural source of soluble fiber, similar to fiber found in grains such as oats and barley.
*The amount of soluble fiber in psyllium is nearly 5X higher than that of oat bran.
100 grams of psyllium = 50 grams of soluble fiber
100 grams of oat bran = 5 grams of soluble fiber
A bulk forming laxative, psyllium fiber is frequently used to treat constipation. It absorbs liquid in the intestines, swells and forms a bulky stool, which is easy to pass.
