I am not a fan of mega dosing of most things, fish oil ( a PUFA ), is one of them. PUFA 's oxidize easily, leading to lipid peroxidation. This is one of the reasons that some studies show reduced longevity in fish oil supplemented mice.
" Survival decreased earlier in the fish oil group than in the other groups (as seen in the survival curve). The results suggest that greater the degree of unsaturation of dietary fatty acids, greater is the tendency for accelerated senescence."

If one is to supplement with fish oil, and I do , 2000mg a day, it should have a tocopherol form of natural vitamin E in it. Also , to reduce lipid peroxidation , supplement with additional gamma E, astaxanthin and CoQ10.

For the prevention of heart disease, supplementing with both CoQ10 and fish oil is better than fish oil alone.
" Treatment with fish oil plus coenzyme Q10 seemed to provide additional beneficial effects to those obtained with fish oil alone, by reducing the rise of cardiac enzymes during AMI as well as the level of pro-inflammatory markers of risk"
