Buying Guide

1. What should I look for in cold water omega-3? Look for high EPA + DHA per serving, molecular distillation for purity, and a cold-water, ocean-sourced origin. Check for certifications like MSC or IFOS when sustainability and purity matter.
2. Which form is easiest to absorb? Re-esterified triglyceride (rTG) forms are often noted for better absorption than ethyl esters; some products highlight burpless or lemon-flavored capsules for easier intake.
3. How much should I take daily? Most products range from 750–1250 mg of omega-3 per softgel with about 690 mg EPA and 260–500 mg DHA per capsule. Start with the label’s recommended dose and adjust based on dietary intake of fatty fish.
4. Is sustainability important? For many buyers, MSC certification, wild-caught sources, and responsible harvesting practices are key indicators of ethical omega-3 production.
5. Allergens and ingredients? If soy-free, gluten-free, or flavored varieties matter, read the label to avoid unwanted ingredients or potential allergens.

Quick buying considerations

• Purity and processing: Look for molecular distillation to reduce contaminants.
• Source and sustainability: Prefer wild-caught, cold-water fish with credible certifications.
• Digestive comfort: Burpless lemon-flavor options can reduce aftertaste or burps.

FAQ

• Who should avoid omega-3 supplements? People with certain bleeding disorders or those taking anticoagulants should consult a healthcare professional before use.
