GreenKare Omega 3-6-9 Plus — Krill Oil vs Fish Oil vs Plant-Based Omega-3

Updated on September 28, 2026

Krill oil has surged in popularity as a "premium" omega-3 option, often priced well above both fish oil and plant-based options like GreenKare Omega 3-6-9 Plus — but does the premium price tag reflect a genuinely better product? Here's an honest three-way comparison.

🐟 Fish Oil

Direct EPA/DHA delivery
Decades of research history
Can cause fishy aftertaste
Not vegan/vegetarian

🦐 Krill Oil

EPA/DHA bound to phospholipids, possibly aiding absorption
Contains astaxanthin naturally
Significantly more expensive per mg of omega-3
Not vegan/vegetarian; shellfish allergy risk

🌱 Plant-Based (Perilla)

Provides ALA, converts inefficiently to EPA/DHA
100% vegan, no shellfish allergy risk
No fishy aftertaste
Most affordable option typically

Krill oil's absorption advantage is real but modest

Some research suggests the phospholipid-bound form of omega-3s in krill oil may be absorbed somewhat more efficiently than the triglyceride form in standard fish oil — but the difference in practical outcomes is generally modest, and doesn't fully justify the often 3-5x higher price per milligram of omega-3.

Sustainability concerns are genuine for krill

Krill are a foundational species in the Antarctic food web, and large-scale krill harvesting has raised real ecological concerns among marine biologists — an environmental consideration fish oil and especially plant-based sources don't carry to the same degree.

Quick tip: If budget is a genuine constraint, standard fish oil or a plant-based option typically offers better value per milligram of omega-3 than krill oil — the modest absorption edge rarely justifies the price gap for most people.

GreenKare Omega 3-6-9 Plus, made from cold-pressed perilla seed oil, offers a vegan, allergy-friendly, more affordable alternative to both fish and krill oil, with a balanced 4:1:1 Omega-3:6:9 ratio and natural vitamin E.
