The omega 3 and omega 6 have a fatty acid “progenitor” from which the body can build other members of the family. Oleic acid is an unsaturated fat of the Omega 9 series and is typical of vegetable oils such as olive oil, avocado, etc. It helps maintain normal blood cholesterol levels.
Our oil comes from different fatty fish depending on the season and availability, and not on farmed fish. No ocean is completely free of contaminants, hence the highly sophisticated processing of our fish oil.
