Is fish oil bad for the liver?

The only instance in which fish oil would be harmful to the liver is if the fish oil is of very poor quality.  In this case it is possible that it has not been processed properly to remove heavy metals and other toxic chemical accumulated in the fish from the pollution in our ocean’s and water ways.  These chemicals can place excess strain on the detoxification pathways in the liver potentially causing damage.

I strongly advise people to read the labels on fish oil supplements carefully to verify that the company ensures the oil has had all heavy metals and other toxic chemicals removed.
