Metamucil and Citrucel are both good choices to help relieve constipation, according to Mayo Clinic. Both are fiber supplements that absorb water. This aids in the development of soft, bulky stools, which stimulates the muscles of the intestines to contract and push out the feces.
Individuals who take Metamucil and Citrucel must drink plenty of water, warns Mayo Clinic. Failing to do so can cause gas, bloating, cramps and worse constipation.
Metamucil and Citrucel are among the safest and gentlest laxatives to use to relieve constipation, states Mayo Clinic, but it is best to address constipation via lifestyle changes before turning to laxatives. Consuming plenty of fiber-rich foods, such as fruits, vegetables and whole grains, drinking lots of fluids, and engaging in exercise can help prevent and relieve constipation.
