Does Rosita’s ancient method affect the nutritional composition of the cod liver oil?

The levels of nutrients (including fat-soluble vitamins A and D and omega fatty acids) present in the liver of a living wild codfish are not significantly different when compared to the oil obtained using the ancient production method employed by Rosita. Experiments and third-party testing at a certified, independent laboratory have been performed to prove this. Nature dictates the nutrient levels in the Rosita oils, which is exactly how it was for our ancestors hundreds of years ago.
