Science-Based Health Benefits of Krill Oil

Science-Based Health Benefits of Krill Oil

Krill oil is a supplement made from a tiny crustacean that is similar to shrimp called Antarctic krill (Euphausia superba) and it is a great source of the omega-3 fatty acids EPA and DHA.

Krill oil is included in Antarctic Krill Oil by Beyond Vita®. 

1. Source of Healthy Fats

Krill oil contains the omega-3 fatty acids called eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) which are used as key structural components of many parts of the body including the brain.1

Fish oil also contains omega-3 fatty acids however, krill oil may be easier to absorb and more metabolically active than fish oil.2

Another study found krill oil to be more effective at increasing blood levels of EPA and DHA after supplementation than fish oil.3

Krill oil contains omega-3 fatty acids and may be more effective at raising EPA and DHA levels than fish oil.

2. Joint Pain and Arthritis

In a 2007 randomized double-blind and placebo-controlled study, researchers found that krill oil supplementation lowered C-reactive protein, an inflammation marker, by over 30% and reduced pain, stiffness and functional impairments in participants with arthritis.4

Another randomized double-blind and placebo controlled study reported that krill oil supplementation reduced knee pain and increased range of motion in 50 participants with mild knee pain.5

Krill oil may help reduce joint pain and improve arthritis.

3. Helps Lower Blood Sugar

Researchers in a 3 month randomized and controlled trial found krill oil to be effective at decreasing blood sugar levels when compared to a placebo and fish oil.6

Krill oil may help lower blood sugar levels.

4. Helps Lower Cholesterol

In the same 3 month study referenced above, researchers reported that krill oil supplementation reduced triglycerides, total cholesterol and LDL cholesterol.6

Researchers in a 2017 meta-analysis of 7 randomized controlled trials concluded that krill oil supplementation can reduce triglyceride and LDL cholesterol levels.7

Other studies also support the beneficial effects of krill oil on cholesterol and triglyceride levels.8,9

Krill oil may help lower cholesterol and triglyceride levels.

5. Premenstrual Syndrome

Omega-3 fatty acids from fish oil have been shown to decrease the pain associated with premenstrual syndrome (PMS) including menstrual cramps.8,9,10

Another study found omega-3 fatty acids may help reduce the psychiatric symptoms of PMS including anxiety, nervousness and depression.11

Krill oil was shown to be more effective than fish oil in alleviating menstrual cramps and the emotional symptoms of PMS in a double blind and randomized clinical trial involving 70 women.12

Krill oil may help reduce menstrual pain and alleviate premenstrual syndrome symptoms.


Krill oil is an important supplement that may be a better source of omega-3 fatty acids than fish oil and may help reduce joint pain and lower cholesterol in addition to other benefits.*
