People with inflammatory bowel disease (IBD) often require extra fluids, electrolytes, and vitamins because the condition causes chronic inflammation of the intestines, which leads to the impaired absorption of nutrients.1

Furthermore, common symptoms of IBD include diarrhea, which results in significant losses of water and essential minerals from the body. Supplemental fluids and electrolytes are necessary to replace these losses and maintain proper hydration and bodily function. Additionally, because the disease interferes with the digestive system's ability to process food effectively, patients may be advised to increase their intake of specific nutrients—such as iron, calcium, and magnesium—and take vitamin supplements to prevent deficiencies caused by malabsorption.1
