Also herring oil.
The higher the
omega-3 to omega-6 ratio, the better.
You can find tables on the web that list the relative essential fattya acid constituentcy of various oils (vegetable, palm, nut, and fish derived).
EPA and DHA are the converted forms of
omega-3 fats that you use directly in brain and other tissues.
I recommend the latter (the NOW products are decent).
My point above: cheap ass fish oils are often derived from trash fish, and have the opposite mixture of omegas (high in 6s and 9s, lower in 3s) than cold water marine fish.
I tried one Wally World
fish oil that literally make my skin break out in red itchy patches, it so jumped up my inflammation response. Think of being bitten about 2000 times by big ass mosquitoes, and you'll understand better my reaction.
I never have this problem with the EPA/DHA EFAs.
