Buying Guide: Key Purchase Considerations

  • Purity and Mercury Removal: Look for products explicitly noting mercury testing, purification steps, or distillation methods to ensure cleaner omega-3 oils.
  • EPA and DHA Ratios: Consider your goals. Higher EPA is often linked to heart and anti-inflammatory benefits; higher DHA supports brain and eye health. Balance per serving to match needs.
  • Serving Size and Daily Dose: Some formulas offer 1 softgel per day, others require 2–3. Choose based on preferred convenience and target intake.
  • Source and Sustainability: Wild-caught and sustainably sourced fish oils appeal to eco-conscious buyers and may influence purity and traceability.
  • Aids for Tolerance: Lemon flavor, burp-minimizing formulas, or odorless softgels improve daily use if taste or aftertaste is a concern.
  • Certifications and Labels: Non-GMO, Kosher, and GMP certifications can indicate manufacturing quality and compliance with dietary supplement standards.
  • Allergies and Dietary Considerations: Check for gluten-free, shellfish-free, or other dietary flags if you have sensitivities.
