Superba™ Krill has an excellent safety record. However, people who have shellfish allergies should not use these products.

Currently there are no known toxicity levels for krill oil. Antarctic krill live in a naturally clean environment, devoid of pollution, so there’s significantly less risk of heavy metals contamination. Superba™ Krill has undergone extensive in vitro, in vivo and human studies to determine its safety and lack of toxicity.

In a recently published human study with 76 men and women, 4 weeks of krill supplementation increased plasma EPA and DHA and was well tolerated, with no indication of adverse effects on safety parameters. People with known allergies to crustaceans (e.g., shrimp, crab, lobster, etc.) should not use krill products.
