Fiber-Psyll

The maltodextrin that is used in the product is Fibersol II by Matsutani. Fibersol II is 90% soluble fiber and thus only imparts very few calories…if I recall the research 1.9 per gram. The calories are correct and it is very effective at doing thejob it was designed for. Look for a new version soon that will be flavorless…it will mix much better in protein shakes.
