What is the recommended dosage for Krill Oil?

General: 500-1,000 mg/day; Lipid Support: 1,000-3,000 mg/day

What are the side effects of Krill Oil?

Potential side effects include: Fishy aftertaste, Mild gastrointestinal discomfort, Allergic reactions in those with shellfish allergy.

What is krill oil and how may it support heart health?

Krill oil is derived from Antarctic krill and contains omega-3 fatty acids bound to phospholipids, along with the antioxidant astaxanthin. Some studies suggest krill oil may improve lipid profiles, though the evidence base is smaller than for fish oil. The phospholipid form may offer different absorption characteristics.

What dosage of krill oil has been studied for cardiovascular outcomes?

Clinical trials have used 1–3 grams of krill oil per day, providing approximately 200–600 mg of EPA+DHA. Due to lower EPA+DHA content per gram compared to fish oil, higher volumes are needed for equivalent omega-3 doses. Most studies lasted 4–12 weeks.

What are the potential side effects of krill oil?

Side effects are similar to fish oil, including digestive discomfort and fishy aftertaste, though generally milder. Individuals with shellfish allergies should exercise caution, though the allergen is typically in the shell protein. Krill oil may enhance anticoagulant effects. It is generally more expensive than fish oil per unit of EPA+DHA.

About

Krill oil delivers EPA and DHA in phospholipid-bound form, which may enhance bioavailability and cellular uptake compared to triglyceride-form fish oil. It naturally contains astaxanthin, providing additional antioxidant protection against LDL oxidation. A 2017 meta-analysis of 7 RCTs found krill oil supplementation significantly reduced LDL cholesterol and triglycerides.

How It Works

Delivers EPA/DHA in phospholipid-bound form which may enhance bioavailability and cellular uptake; contains naturally occurring astaxanthin providing additional antioxidant protection against LDL oxidation; supports healthy lipid metabolism through PPAR-alpha activation and reduced hepatic lipogenesis.
