ナンキョクオキアミ
Krill oil is an extract prepared from a species of Antarctic krill, "Euphausia superba". 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).
