What is Krill Oil for?

Krill Oil is an oil extracted from a tiny, shrimp-like animal called krills. In Norwegian, the word ‘krill’ means ‘whale food’.

It is also claimed to improve cardiovascular health by lowering blood lipids, lowering blood pressure and preventing blood clot formation, but there is limited scientific evidence to support these claims.
