>Cod liver oil contains EPA, DHA, and natural vitamins A & D.  Most omeg-3
fish oils
>capsules contain only EPA.  So, you miss out on the all-important DHA.
Also, the A & D


Do you or somebody else know how cod liver oil is made , and how omega 3
fish oils are made?
what is the process to extract thoses oils.
How do they avoid rancidity of thoses oils once extracted. ?

I have access to lot of salmon heads that are very rich in fat and i could
extract oil from it instead of letting go to "waste". ( not  that my garden
mind composting it. but may be it could be helpfull to  malnourished
humans.)

An other question:
is salmon fats are only Epa and don't have VIt A and D.like you said about
fish oils capsules.?
