Strong for IBS symptom relief health 6 linked sources Content audit 2026-05-16

Headline Finding

IBS meta-analysis: 12 RCTs with 835 patients found peppermint oil superior to placebo for global symptoms and abdominal pain.

Dose Context

Trials usually use enteric-coated capsules before meals for short periods; ordinary peppermint tea or essential oil is not equivalent.

Important Caveat

Can worsen reflux or cause heartburn. This evidence applies to oral-use capsules, not general essential-oil ingestion.

How To Read This Rating

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
