Abstract

The essentiality of iodine for man is well recognized. The primary sources of iodine in a
normal, balanced diet are fish, shellfish, milk and iodinated salt. Alternative sources of iodine
meant to complement the normal diet are food supplements containing iodine. The complex
composition of food supplements, due to their content of various vitamins and minerals,
makes determination of iodine very difficult. In our work we employed radiochemical neutron
activation analysis to determine the content of iodine in different series of seven different food
supplements available on the Slovene market intended for adults, children and sportsmen.
The levels of iodine found ranged from 21 to 231 μg/g. Three food supplements were not in
agreement with the declaration made by the producer and two food supplements were not in
agreement with the recommendations made by U.S. Pharmacopoeia that dietary
supplements should contain not less then 90 % and not more then 200 % of the declared
amount of substance.
