Krill oil

Processed krill oil is commonly sold as a dietary supplement.

Two components of krill oil are omega-3 fatty acids similar to those in fish oil, and phospholipid-derived fatty acids (PLFA), mainly phosphatidylcholine (alternatively referred to as marine lecithin).

Although there may be toxic residues present in Antarctic krill and fish,[2][3] the United States Food and Drug Administration has accepted notices from krill oil manufacturers declaring that krill oil and supplement products derived from it meet the standards for generally recognized as safe (GRAS) status.

[4][5] Krill oil is listed among authorized European novel foods by meeting specification limits.

[7][8] Krill oil also contains an appreciable content of astaxanthin at 0.1 to 1.5 mg/ml, depending on processing methods, which is responsible for its red color.
