Healthy benefits beyond irregularity


The following are the most frequently asked questions about Metamucil products and psyllium fiber.

Q: Why have the drug facts, drug information been removed from the Metamucil Powders labels?

Q: Are Metamucil fiber gummies made with the same fiber as Metamucil psyllium powders?

A. Metamucil fiber gummies are made with a plant-based fiber blend of Fibersol® (soluble corn fiber) and inulin that help promote digestive health*. They do not contain psyllium husk and therefore do not have the same multi-health benefits as Metamucil powders & capsules.

Q: How are the types of fiber different?

A. Soluble fibers dissolve in liquid and insoluble fibers do not dissolve in liquid. Soluble fiber is further subdivided into viscous and non-viscous fiber. Some viscous soluble fiber (such as the kind in Metamucil psyllium fiber) forms a viscous gel. Insoluble fibers do not form gels and move through the GI tract largely intact. Most fibers are exclusively soluble or insoluble but not a mixture of both types. Visit to learn more about different types of fiber and the fibers used in Metamucil fiber supplements
