Krill Oil

Also known as: Euphausia superba oil · Neptune krill oil

●●○Moderate Evidence

Omega-3s bound to phospholipids (vs triglycerides in fish oil) — better cell membrane integration at lower doses. Naturally contains astaxanthin as an antioxidant stabiliser.

What Is Krill Oil?

Krill oil provides EPA and DHA in phospholipid form — structurally identical to the phospholipids in cell membranes. This may improve incorporation into membranes vs fish oil's triglyceride form, potentially allowing lower doses to achieve equivalent effects. It naturally contains ~200mcg astaxanthin per gram, providing in-built antioxidant protection.

How It Works: The Science

Phospholipid-bound omega-3s are directly incorporated into cell membrane phospholipids without the re-esterification step required for triglyceride-form EPA/DHA. This may produce faster and more efficient membrane enrichment. Astaxanthin protects the omega-3 fatty acids from oxidation both in the product and in vivo.

Primary Mechanism

Phospholipid-bound EPA/DHA — superior membrane incorporation

Evidence-Based Benefits

Reduces PMS symptoms (cramps, mood) more effectively than fish oil

moderate

Sampalis et al. (2003) — krill oil significantly superior to fish oil for dysmenorrhoea

Improves lipid profile (reduces triglycerides, raises HDL)

moderate

Bunea et al. (2004) — significant improvements in all lipid markers vs fish oil and placebo

Dosage Guide

Effective Dose

1–3g / day

1–3g krill oil/day (providing ~200–500mg EPA+DHA). Lower absolute EPA/DHA dose needed vs fish oil — verify the EPA/DHA content on the label, not just total krill oil volume.

Safety Profile & Side Effects

Contraindicated in shellfish allergy (krill are crustaceans). Same blood-thinning considerations as fish oil. More expensive than fish oil per mg of EPA/DHA.

Who Should (and Shouldn't) Take It

Best for

Joint healthCardiovascularPMSBrain health

Who it's for

Those who prefer phospholipid-form omega-3 or have GI issues with fish oil. Also those wanting built-in astaxanthin. Women with severe PMS. Budget-conscious consumers get better EPA/DHA value from fish oil.
