Whenever you take supplemental oils or essential fatty acids, always take extra vitamin E, as mixed tocopherols, to prevent the oils from oxidizing too rapidly in your body. Take 800-1,000 IU of
vitamin E with 2 to 3 tablespoons of cod liver oil each day.
And to minimize any gastrointestinal upset, split the cod liver oil into two or three doses. It's not very tasty stuff, so if necessary, you can blend it with rice or almond milk.
