Fermented cod liver oil is one of the very few food sources for vitamin D in supplement form. I take this along with raw milk, much superior to dead milk. Raw milk does not have Vitamin D but it does have vitamin B12, vitamin B6, carotenoids, calcium, phosphorous, magnesium, and iron, as well as omega-3 fatty acids, conjugated linoleic acid, vitamin K, and a number of digestive enzymes
