Step 1 · First-line care

What to do first

Self-care is for mild, familiar symptoms after IBS-C has been assessed. Change one option at a time, follow the product label, and seek care for warning signs or symptoms that persist or worsen.

Some evidence1 source

Peppermint Oil

Enteric-coated peppermint oil capsules should be taken as directed. The standard adult dosage is 0.2 to 0.4 mL (180-400 mg) three times daily, typically 30 to 60 minutes before meals to ensure the capsule passes through the stomach while empty and releases in the intestines.

What does this evidence mean?

Enteric-coated peppermint oil (a concentrated essential-oil preparation) has randomized controlled trial evidence and meta-analyses reporting benefit versus placebo for global symptoms and abdominal pain in adults with irritable bowel syndrome (IBS).

Evidence may apply to one specific form of an ingredient — a capsule, extract, cream, or tea — and to a particular amount. Recipes and everyday foods may not match the form or amount that was studied.

For ongoing support

These options are better suited to regular or longer-term use than to quick symptom relief.

Some evidence1 source

Psyllium

May improve stool frequency and constipation symptoms in adults with IBS-C; evidence is for psyllium fiber, not every fiber product.

How it is used: Use a commercial psyllium product according to its label, mix each dose with the specified amount of liquid, and increase gradually to reduce gas or bloating. Do not take it dry.

What does this evidence mean?

A systematic review and meta-analysis of randomized trials supports a possible benefit of fiber supplementation in IBS, but results may vary by fiber type and the evidence is not specific enough to establish benefit for every psyllium product or all IBS-C symptoms.

Evidence may apply to one specific form of an ingredient — a capsule, extract, cream, or tea — and to a particular amount. Recipes and everyday foods may not match the form or amount that was studied.
