Buying Guide

What should you consider when buying omega-3 krill oil?

  • Potency per serving: Decide whether you want 350 mg, 500 mg, or 1000 mg per softgel based on your goals and doctor’s advice.
  • Absorption and phospholipid form: Krill oil binds omega-3s to phospholipids, which can improve absorption and reduce fishy aftertaste for many users.
  • Astaxanthin content: This antioxidant helps stabilize the oil and adds a natural coloration, potentially supporting freshness.
  • Purity and sourcing: Look for brands that specify Antarctic krill and traceability from sea to bottle.
  • Capsule type and size: Choose full-size softgels for fewer pills or mini-softgels for easier swallowing.
  • Allergies and dietary considerations: Check for non-GMO, gluten-free, and other certifications if applicable to your needs.

How to compare products quickly

  • Best for high-dose daily use: 1000 mg per softgel options.

  • Best for portability: Mini-softgel formats with convenient daily dosing.

What about safety and usage?

  • Follow labeled directions and consult a healthcare provider if you have a medical condition or take anticoagulants.
