Ethylenediamine dihydroiodide (EDDI) is added to pet food and cattle feed to prevent iodine deficiency. [5] A controversial additive is arsenic, often supplied in the form of the organoarsenic compound called roxarsone. It has been used in poultry production to increase weight gain and improve feed efficiency, and as a coccidiostat.

The signs and symptoms of niacin deficiency start to revert within days of oral supplementation with large amounts of the vitamin. [23] [24]
In areas where there is little iodine in the diet, typically remote inland areas and semi-arid equatorial climates where no marine foods are eaten, iodine deficiency also gives rise to hypothyroidism, the most serious symptoms of which are epidemic goitre (swelling of the thyroid gland), extreme fatigue, mental slowing, depression, weight gain ...
