I'm often asked about the differences between fish oil and cod liver oil. Which is best? Both have anti-inflammatory EPA-DHA, but there's more to know before buying. Eating oily fish such as wild salmon and sardines twice a week is important but it makes sense to supplement a small amount of Omega 3's as well. So, Fish Oil or Cod Liver Oil? One thing is true for both. Quality counts! The brand, the processing method and the type of fish all matter.
