Chris Masterjohn: Precious Yet Perilous
Basically, using lots of Fish Oil over many years is probably not a good idea...
If you are trying to balance your Omega 3:6 ratio, the best way to do it is to reduce your Omega-6 intake and eat fish 2 or 3 times per week — rather than downing lots of Fish Oil. You can take therapeutic doses of Fish Oil (as MG is doing) to raise your Omega-3, but it's not a good long term solution, since it just increases the amount of oxidizable polyunsaturates in your body. A therapeutic dose of Fermented Cod Liver Oil could be up to 15mL to fight colds and other illnesses.Chris Kresser wrote:This may come as a surprise to you, with all of the current media hoopla about the benefits of fish oil supplementation. Yet the vast majority of the studies done that have shown a benefit have been short-term, lasting less than one year. The only trial lasting more than four years, the DART 2 trial, showed that fish oil capsules actually increase the risk of heart disease and sudden death.
A 2004 Cochrane meta-analysis of trials lasting longer than six months suggests that the cardiovascular benefits of fish oil have been dramatically over-stated. They analyzed 79 trials overall, and pooled data from 48 trials that met their criteria. The only effect that could be distinguished from chance was a reduced risk of heart failure. Fish oil provided no reduction in total or cardiovascular mortality.
Too much fish oil can wreak havoc in your body
Omega-3 fatty acids are highly vulnerable to oxidative damage. When fat particles oxidize, they break down into smaller compounds, like malondialdehyde (MDA), that are dangerous because they damage proteins, DNA, and other important cellular structures.
A study by Mata et al demonstrated that oxidative damage increases as intake of omega-3 fat increases.

For maintenance doses, maybe limit Fish Oil to 1 gram and Fermented Cod Liver Oil to 5mL. That's just a rough estimate — everyone is different. (I'm not a doctor, so do your own research).
