It is found in marine algae, sea fish (fresh cod, sardines, mackerel …), smoked herring and cod liver oil or crustaceans, oysters and shellfish. It is also present in plants such as soybeans or green beans. Finally, it can also be found in dairy products, eggs and meat.
Seaweed, seafood and fish are the richest iodine foods globally. Consume mussels, oysters, haddock, etc., thus allows to bring a significant amount of this trace element. Dairy products and eggs are also a favorite food item. As for mineral water, it also has an iodine content, which however differs according to the soil.
