Krill oil is derived from small crustaceans (Euphausia superba) and provides EPA and DHA omega-3 fatty acids in phospholipid form, which some research suggests may improve absorption compared to the triglyceride form found in standard fish oil. Krill oil also naturally contains astaxanthin, a potent antioxidant that gives it its red color. EPA and DHA concentrations per capsule are typically lower than in fish oil, meaning more capsules may be needed to reach the same daily dose. Products below are ranked by the cost of your chosen daily dose of combined EPA+DHA, extracted directly from each product's Supplement Facts label.

This is the current ranking surface for Omega-3: Krill Oil. It recalculates cost per month from product price, Supplement Facts active amount, servings per container, and the dose you enter above.
15 active products have enough price and label data to calculate cost before display filters; 15 rows are currently shown in the ranked table. The current review floor for this category is 10+ reviews before any large-category and duplicate/bulk filtering.
At 1000 mg/day, visible products range from $4.49-$31.99/mo with a $14.99/mo median midpoint and a 7.1x low-to-high spread.
Read the EPA and DHA amounts instead of relying on total krill oil. Labels reviewed for this update included krill softgels where phospholipids, astaxanthin, EPA, DHA, and total omega-3s were listed in different ways.
Cost depends on EPA+DHA concentration, phospholipid positioning, astaxanthin claims, softgel count, and sourcing or freshness claims. A high total krill oil amount can still be expensive if EPA+DHA is low.
Do not treat total krill oil, total omega-3, phospholipids, astaxanthin, and EPA+DHA as the same number. TrueServing focuses on the omega-3 target, while phospholipid and astaxanthin claims remain separate buyer considerations.
Krill oil has moderate evidence as an omega-3 source, with some absorption interest due to phospholipid form. TrueServing compares labeled krill oil products by EPA+DHA at 1,000 mg/day and does not rank freshness or sustainability claims.
