Answer:

Fermented cod liver oil, such as Blue Ice (Green Pastures), is sometimes touted as a more natural, superior source of vitamins A and D, and the omega-3 fatty acids EPA and DHA. However, there does not appear to be any clinical evidence demonstrating that fermented cod liver oil is more beneficial than regular cod liver oil. And, unlike many regular cod liver oil supplements, most fermented cod liver supplements do not list their amounts of vitamin A, D, or EPA and DHA on the label, so there is no way to know exactly how much you are getting. For more information, plus our tests and comparisons of other cod liver oil supplements, see the Review of Vitamin A Supplements Including Beta-Carotene and Cod Liver Oil >>

Hi folks,

I hope that in future fish oil/cod liver oil reviews you guys could take a look at ROSITA cod liver oil? They say that their A & D are natural and not added like other cod liver oils. It's an expensive cod liver oil so any testing & evaluation would be most appreciated. :)

Hi Renee - Thank you for your suggestion; we will keep it in mind. Also be sure to take our annual survey, sent each fall by email to our newsletter readers -- the results help us decide which products and brands to test.
