Psyllium Husk : A highly water soluble ingredient, it actually forms a gel when mixed with water and is slow fermenting. For decades, psyllium has been used as a laxative, but not just any type of laxative. It works primarily by increasing fecal weight and stool size thanks to its combination with gas and water in the colon and small intestine. This function is extremely versatile, because it can both solidify stool for those who are too soft, but soften it in the opposite situation. Ultimately it leads to easier passage of stools and helps reduce diarrhea, as opposed to causing it. Research has shown that psyllium husk can consistently reduce appetite, especially 3 to 6 hours after ingesting enough of it. Those are larger doses between 10 to 20g per serving, so you need to take a few scoops of the fiber to get those effects. In addition it has been shown that psyllium husk has consistently reduced blood sugar levels.
