Krill oil is oil extracted from small, shrimp-like sea animals known as Euphausia Superba. The whole “krill” in Norwegian means “Whale food” because whales, mantas and sharks alike feast on these tiny animals.
The oil extracted from these animals is encapsulated and high in demand for its benefits in treatment for heart diseases, elevated blood fats levels (triglycerides) and high levels of cholesterol. However, there is limited research to back up these claims.
People who experience allergic reactions to seafood may also be hypersensitive to krill oil. There is not enough evidence to determine how much people are allergic to seafood to show allergic reactions to krill oil. It is advisable to use krill oil cautiously if you are allergic to seafood.
