There is not enough authoritative data to provide specific dosing recommendations for peppermint oil, so it’s best to consult a healthcare professional for personalized guidance. Peppermint oil can be taken as needed for digestive relief, often before or after meals, and may be taken with or without food—taking it with food can help reduce stomach irritation. It is available in various forms, with enteric-coated capsules commonly used for digestion and topical oils for muscle or headache relief.
