One of the best known home remedies for constipation is fiber. The recommended dosage — 20 to 35 grams per day — can be found in fruits, vegetables, and whole grains. Fiber is also a convenient constipation remedy since most people already have these items in their homes. Fiber supplements such as psyllium (Metamucil) or methylcellulose (Citrucel) can be used as well.
The one downside to using fiber as a constipation home remedy is that it can actually make constipation worse if you don’t drink plenty of water with it. For the fiber to help alleviate constipation, it needs fluids to help move it through the digestive system. Fiber derived from supplements especially must be taken with water in order to avoid worsening constipation.
