Does fish oil help damaged nerves?

Maybe: There is some evidence suggesting certain omega 3 fatty acids (found in fish/fish oil) may help nerves. I don't think we can say this definitively yet, but omega 3's have been/are the subject of much study. There are also other reasons why eating more fish/getting more omega 3's may be helpful for your health. Talk with your doctor about your particular situation.

Doubtful: Krill oil and fish oil are the new snake oil, both are high in omega 3 fatty acids which are extremely fragile. Omega 3 fish oils reduce triglycerides by impairing the liver's ablility to make them. However the oxidative stress caused by fish oil actually raises LDL cholesterol. Some day we may use the phrase "this is just more fish /krill oil" or "here comes the fish/krill oil salesman".
