Psyllium husk is the seed husk portion of the Psyllium plant (Plantago ovata). Medically, it is mainly used a bulking agent due to its high fiber content of 67-71% and as a mucilage agent with a content of 10-30%.1 While psyllium husk has not been shown to completely resolve candida overgrowth, it may be helpful in reducing it because the soluble fiber and mucilage act to bulk stool and regulate bowel movement. Candida feeds on partially digested sugar and carbohydrate molecules in your intestines, so it is important to have regular and complete bowel movements.
A fiber supplement like psyllium husk is often recommended during treatment of candida yeast overgrowth. During digestion, the psyllium absorbs water in the colon forming mucilage, a sticky gel-like substance which pulls in fecal matter and toxins as it moves through the colon.1,2 This process of removing toxins properly manages die-off. Studies confirm that psyllium has no prebiotic or probiotic effects on gut flora.7
