Lemon Balm Buyer's Guide: What to Look For
Form: Capsules offer convenience and precise dosing. Liquid tinctures absorb faster—ideal for acute anxiety or bedtime use.
Standardization: Look for products standardized to rosmarinic acid (typically 4% or higher), the key active compound. Avoid "proprietary blends" that hide exact amounts.
Dosage: Clinical studies typically use 300–1,600 mg of lemon balm extract daily. Start low and adjust based on your response.
Organic Certification: Choose USDA Organic or equivalent if you prioritize pesticide-free sourcing.
Third-Party Testing: Prioritize brands that disclose independent lab testing for potency and contaminants.
