Members widely agreed that Metamucil often causes uncomfortable bloating, gas, and cramping that many with IBS simply cannot tolerate, with several describing nausea and one wondering if it might affect vitamin absorption or cause easy bruising. Many community members shared alternatives they've found more gentle, including Benefiber (recommended by some GI doctors), Phillips fiber gummies, and Metamucil gummies, though experiences varied with powder versus capsule forms and flavors. A recurring theme was the trial-and-error process of finding a fiber supplement that works for your body, with most agreeing that the traditional Metamucil powder often does more harm than good for sensitive digestive systems.
