It was established on the basis of questionnaire responses that consumers of food supplements knew very little about selenium and its effects on human body. Selenium was determinate in selected food supplements. The digestion of the samples was made by using HNO3 and H2SO4 acids and the detection by HG-AFS. It was found that the obtained value of selenium in one selected product far exceeded the declared value. We did not find Se species which were declared. It would make sense to introduce control of selenium content in food supplements and to assure the safety and quality of these products.

COBISS.SI-ID: 22121255Plants were sown on field and at flowering phase we sprayed one group of plants with 10 mgSe(VI)/L).Harvest was done 75 days after sowing. Se content, regarding to various parts of plant, 50- to 500-fold higher than in control group. We can see very similar selenium distribution in plant parts in both groups. In seeds we found 95 % SeMet, that is 60 % of all Se in sample and we found only 12 % soluble Se in leaves. For possible use of selenium enriched buckwheat in human diet we should control foliar spraying and monitor selenium content in seeds and diet.
