Cod Liver Oil vs. Fish Oil: Is there a Difference?

Summary

This video discusses the differences between cod liver oil and fish oil, highlighting that cod liver oil contains less omega-3 fatty acids (EPA and DHA) compared to fish oil. Despite this, the presenter prefers cod liver oil for its high levels of vitamins A and D, which are beneficial for eye health, immune function, and reducing the risk of kidney stones. Fish oil, on the other hand, is praised for its anti-inflammatory properties and benefits to the brain, heart, and nervous system. The video also clarifies that while other sources like walnuts and flaxseed contain omega-3, they are in the form of ALA, a precursor that requires conversion to the more active EPA and DHA. The recommendation is for virgin cod liver oil, which is less processed and naturally rich in vitamins A and D.
