Buying advice

Look for oregano products standardized to at least 70% carvacrol for potency. Liquid extracts offer faster absorption but can be intense; capsules or softgels are more convenient and mask the strong taste. Verify the supplement is from oregano (Origanum vulgare) and not other plants like Mexican oregano. Enteric coating can reduce stomach irritation. Always follow the recommended dosage and consult a healthcare professional before use, especially if pregnant, nursing, or on medication.
