| dc.description.abstract | An adequate vitamin D (vitD) intake (Recommended Daily Allowance, RDA= 5μg) is crucial for health maintenance and its deficiency is associated with several health problems. The increase in hypovitaminosis D cases and the proliferation of food supplements (FS) that are easily accessible by the population, have led to an unrestrained chronic consumption of FS. VitD may accumulate in the body and originate toxicity (Tolerable Upper Limit, UL=100 μg). The aim of this study was to evaluate if daily vitD doses mentioned in FS labels are in conformity with RDA. 210 solid and liquid FS (for pediatrics and adults) sold in Portuguese pharmacies, supermarkets, health shops and on the internet were examined for indicated daily intake of vitD and compared to RDA and UL values. 51.43% of FS have values higher than RDA, 8.57% higher than UL. The average vitD daily dose in FS is 24.48 μg, with a high variability between samples (0.25 - 250 μg). Majority of FS labels recommend vitD daily doses above RDA and some even above UL, regardless of being for adults or children. Therefore, it is crucial that vitD dose in FS is reviewed to ensure the safety of these products. | pt_PT |
