The amount of iodine in a fish oil will depend on what type of fish oil you’re using and it can even vary from brand to brand. For example, cod is rather high in iodine so a cod liver oil will contain more iodine than some other types of fish oil. The best thing to do would be to contact the company that manufactures your fish oil you’re using to obtain the exact iodine levels. If you have the patience, you could contact the company for each food you feed to obtain the iodine levels, contact Solid Gold to get the iodine levels of the supplement and get the iodine levels of the fish oil and see what type of daily iodine intake you’re looking at. He shouldn’t be getting more than 50 mg. iodine per kilogram of food.
