Fish oil pills are the third most-bought food supplement, after vitamins and minerals, and are bought by 10 percent of North Americans at a cost of about $1.2 billion each year. However, fish oil pills have not been shown to help prevent heart attacks, even though people who eat fish have been shown to have a reduced incidence of heart attacks.
You get your maximum protection from eating fish twice a week. Eating fish more often than that has not been shown to offer further protection from heart attacks.
If you break open a fish oil capsule and it smells or tastes fishy, it is rancid and should be discarded.
