It is estimated that 33% of the UK adult population regularly use dietary supplements (1) . When estimating nutrient intake in a population this additional source of vitamins and minerals can substantially increase consumption (2) . A major challenge of estimating nutrient intake from dietary supplements is incomplete brand information supplied by study participants to allow exact identification of the supplement. To avoid underestimation of intake caused by missing data, previous studies have

The aim of this work is to investigate the effect of applying a generic pregnancy multivitamin-mineral supplement (MVMS) to estimate the nutrient intake of pregnant women reporting taking a MVMS compared to intake calculated using reported branded supplements. Data was collected from 152 pregnant women participating in a study assessing Vitamin D and E intake. Dietary and supplement information was collected using the Scottish Collaborative Group's FFQ (v6·6) (4) . A 'generic' MVMS was created using the weighted average of the nutrient composition of reported supplements. Supplement intakes were then calculated using both the reported brand, and the generic supplement nutrient compositions. The calculated nutrient intakes for each method were then compared using the Wilcoxon signed-rank test. Ninety two women reported taking a MVMS designed for use in pregnancy. A core set of 14 nutrients were included in the majority of branded supplements (Vitamins
