US standards limit “cod liver oil” to A to 2500 IU and Vitamin D to 250 IU per gram.
Many cod have far higher amounts than the US regulations.
Commercially all of the cod fat is used, not just that fat coming from the liver.
Commercial process removes most of the natural vitamin A and all of the vitamin D from the fat.
Then artificial vitamins are added back to meet the US standards
