Krill oil: new nutraceuticals

Krill oil is a new available health product which is produced from deep marine species, namely, krill. Krill lives in deep sea in the area of new global polar. It is a marine crustacean species enriching in both eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Due to the good environment, krill exposes to very few pollutants. As a deep sea animal, krill contains good omega-3 lipid, similar to deep sea fishes. Recently, nutritional scientists successfully produced oil from krill and called krill oil. Its property is to promote good health. The good lipid composition and antioxidant enrichment make krill oil a new neutraceutical for reducing health problems. Ulven et al. noted that metabolic effects of krill oil are essentially similar to those of fish oil but at lower dose of EPA and DHA, in healthy volunteers[1]. Also, it is proved for no toxicity to intestinal lumen[2]. Maki et al. concluded that krill oil supplementation increased plasma EPA and DHA and was well tolerated, with no indication of adverse effects on safety parameters[3]. Here, several advantages of krill oil for human beings are reviewed and presented.
