So now that you want to take fish oil, what to look for in buying:
-Molecular Distillation for purity
-Types of fish listed: smaller fish, like sardine and herring and short lifespans
-EPA and DHA content: most common is 180mg EPA and 120mg DHA (written 180/120). There are concentrated doses available
Footnotes:
Cod Liver Oil is not a good option if you are strictly after EPA/DHA
Meg-3 is probably one of the best "sources" of omega 3s. Used in some of the major brands out there:

Since they are from the same source, best value may be from generic store-brand (e.g. Costco/Kirkland).
I've started biting the capsules to see (taste) how fresh they are. If they are rancid, will know it right away. Never has happened to me so far with capsules (but has with liquid oil - dont forget to put in fridge)
