ABSTRACT 134.-----------------------------------------------------------------Food supplements are defined as products for increasing the habitual daily ingestion, supplementing some nutrients in the diet of the healthy people, being their administration by oral route. The objective of this work was to analyze minerals and vitamins of 14 food supplements from Tahefarma SRL (San Luis), and to compare them with the recommended daily intake (RDI) and possible adverse effects of those nutrients according to Argentinean Alimentarius Codex (AAC). Vitamins and minerals were determined by AOAC methods and atomic absorption spectrometry. From vitamins and minerals analyzed was concluded that samples8, 9, 12 and 14 do not provide 20% of RDI required by AAC for healthy adults. Deficiencies were observed in the samples: 8 (Vitamin B3), 9 (Vitamins C, B6, B2), 12 (Mg and Vitamin B5), 14 (Vitamins C and B6). When vitamins and minerals were correlated with RDI for children, pregnancy and lactation, deficiencies in Vitamins B3 and B5 (samples 8, 12) were also observed, but AAC recommends not to use supplements in those populations. Besides, adverse effects were not observed for healthy adults in none of the analyzed supplements.
