If psyllium husk is a carbohydrate, why do Metamucil Capsules contain zero net carbs?
In strict scientific terms, natural psyllium fiber is a polysaccharide that is a subclass of carbohydrates. Although dietary supplement regulations require that we list psyllium fiber as part of the carbohydrate total, it is, in fact, very different from carbohydrates such as sugar, glucose, fruit sugar, corn syrups, and starches. This is because our gastrointestinal enzymes cannot digest psyllium; therefore, our bodies do not absorb it and do not convert it into glucose.
