How many metamucil capsules should i take daily for ibs?

Depends on symptoms: Metamucil is a bulk forming fiber supplement laxative. How many to take depends on your symptoms and your dietary fiber intake. I would shoot for 25 to 40 g of fiber a day in your diet. You can adjust the dosage of Metamucil to help you achieve symptom control. I would not go over 40 g a day total. Remember to stay hydrated, and to be wary of drug-food interactions. Good luck.
