OBJECTIVE: To describe supplement use practices among non-pregnant, non-lactating Mexican women (12-49 y) and estimate their impact on the proportion of women with intakes below the Estimated Average Requirement (EAR) and above the Upper Limit (UL) using data from a national probabilistic nutrition survey in Mexico (1999). METHODS: Information was collected by questionnaire on the frequency and duration of supplement use in the previous 6 months (n = 17,794). Dietary intakes by 24-hour recall were determined in a representative sub-sample (n = 2,599). Frequency of use and available information on the nutrient content of supplements was used to estimate daily equivalent intakes. RESULTS: 17.6% of women reported to have used supplements. The majority of these took supplements once daily (71%) and for < or =2 months (75%). While nutrient intakes from diet alone did not differ between users and non-users, the proportion with intakes of Vitamins A, B(6), B(12), and C, folate, iron, and zinc < EAR were significantly greater among the supplement non-users when intakes from supplements were also considered. The proportion of women with intakes > UL was greater among supplement users than non-users for iron, folate and Vitamin B(6). CONCLUSION: Supplement use contributes to the adequacy of nutrient intakes but may also increase the possible risk of toxic intakes of some nutrients among Mexican women.
