Once a standard supplement in traditional European societies, cod liver oil provides fat-soluble vitamins A and D, which Dr. Price found present in the diet of primitives in amounts ten times higher than the typical American diet of his day. He considered cod liver oil important for both children and adults. Women and their male partners should take it for at least several months before conception, and also during pregnancy. Growing children will also benefit greatly from a small daily dose.

Cod liver oil is also rich in eicosapentaenoic acid (EPA) and docasahexaenoic acid (DHA). The body makes these fatty acids from omega-3 linolenic acid. EPA is as an important link in the chain of fatty acids that ultimately results in prostaglandins, localized tissue hormones while DHA is very important for the proper function of the brain and nervous system. Those individuals who have consumed large amounts of polyunsaturated oils, especially partially hydrogenated oils, who are suffering from certain nutrient deficiencies, or who have impaired pancreatic function, such as diabetics, may not be able to produce EPA and DHA and will, therefore, lack important prostaglandins and necessary fats for the brain unless they consume oily fish or take a cod liver oil supplement.

Dr. Price always gave cod liver oil along with high-vitamin butter oil, extracted by centrifuge from good quality spring or fall butter. He found that cod liver oil on its own was relatively ineffective but combined with high vitamin butter oil produced excellent results. The butter oil contains what he called Activator X, now considered to be vitamin K2, which works synergistically with vitamins A and D. Your diet should include sources of vitamin K, such as good quality butter from grass-fed cows and/or high-vitamin butter oil, fat from grass-fed animals, cheeses from grass-fed animals and duck or goose liver, along with cod liver oil.
