01/01/2013 - "Increasing of omega-3 PUFA diet level improved vitamins A and D sufficiency to some extent, but was accompanied by the significant reduction of rat liver alfa-tocopherol content both under combined vitamin deficiency (by 14%) and increased vitamins consumption (by 43%). "
05/01/1992 - "Vitamin administration to the workers with "Undevitum" resulted in a significant improvement of their vitamin status that was expressed in elevation of their biochemical parameters and in diminution of the percentage of subjects with vitamin deficiencies."
08/01/2002 - "Moreover, we wanted to assess if there are differences between fat-soluble vitamin profiles in patients with impaired versus patent exocrine pancreatic function, and thirdly, if fat-soluble vitamin deficiency at diagnosis is effectively treated by supplementation. "
07/01/1990 - "Administration of "Undevitum" in a dose of 1 dragee/day during 4 months eliminated the vitamin deficiency in the ration and provided optimum vitamin levels for the students."
