Frequently Asked Questions (FAQs)

1. What supplement is a good source of fiber?

Best Overall: Konsyl Daily Psyllium Fiber Although psyllium is sold in many supplements, we prefer Konsyl's organic ground psyllium husk because it is free of added ingredients which can worsen symptoms, such as sugar alcohols and artificial sweeteners.

2. Is it OK to take fiber supplements daily?

Answer From Michael F. Picco, M.D. There's no evidence that daily use of fiber supplements — such as psyllium (Metamucil, Konsyl, others) or methylcellulose (Citrucel) — is harmful. Fiber has a number of health benefits, including normalizing bowel function and preventing constipation.

3. Are fiber pills as effective as powder?

Insoluble fibers don't dissolve in water, but help move along intestinal contents and hydrate the stool. This can help with constipation or irritable bowel syndrome. Which Is Better, Capsules, Tablets, or Powders? It doesn't really matter which form the fiber comes in.

4. What is the best fiber to make you poop?

There are two kinds of fiber: soluble and insoluble. Soluble fiber gives stool bulk. Foods that are good sources of soluble fiber include apples, bananas, barley, oats, and beans. Insoluble fiber helps speed up the transit of food in the digestive tract and helps prevent constipation.
