Buying Guide

Formulation: oil vs. softgel

Choose softgels (e.g., North American Herb & Spice, Swanson) for measured dosing and milder taste; liquid oils (e.g., Natural Factors, Gaia Herbs) offer flexible dosing and faster absorption

Active compounds: carvacrol content

Look for products that list carvacrol or oregano oil concentration since this compound is commonly used to standardize potency and support antimicrobial activity

Additional ingredients

Check for complementary oils like black seed oil (Micro Ingredients) or antioxidant formulations (Gaia Herbs) that can affect tolerability and intended benefits

Certification and sourcing

Prioritize organic or third-party tested options (Natural Factors is organic) and note whether the oregano is wild-harvested or cultivated to match your preferences

Intended use and label claims

Match the product to your goal—immune support, digestive or urinary tract support—and follow label dosing; some formulas target broad antioxidant benefits while others emphasize specific systems
