About NuSyllium Organic Natural Fiber
NuSyllium Organic Natural Fiber is 100% organic certified psyllium fiber. Psyllium fiber comes from the outer coating, or "husk" of the psyllium, or, Plantago ovata, plant 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.
