Introduction	Despite a long-term trend of rising dietary supplement consumption since the 1970s, comprehensive recent data for the UK population have been lacking. This analysis aimed to quantify dietary supplement use utilising data from the NHANES 2003-2006, a national, cross-sectional survey. Supplement consumption was examined across the UK population (ages 1 year and above) categorised by DRI age groups. A questionnaire assessed supplement consumption, revealing that 49% of the UK population (44% of males, 53% of females) reported use. Multivitamin-multimineral products represented the most common type of dietary supplement reported (33%). Most individuals indicated consuming only one dietary supplement, typically on a daily schedule. Consumption patterns indicated lower rates among obese adults, with higher prevalence among non-Hispanic whites, older demographics, and individuals with higher educational attainment. Specific nutrient supplements were also prevalent: 28-30% reported using supplements containing vitamins B-6, B-12, C, A, and E; 18-19% used those with iron, selenium, and chromium; and 26-27% consumed zinc- and magnesium-containing supplements. Botanical supplement consumption was more frequent in older age groups compared to younger ones, with the lowest rates in individuals aged 1-13 years, yet approximately 20% of adults reported their use. Overall, approximately half of the UK population and 70% of adults aged 71 years or older utilise dietary supplements, with one-third specifically taking multivitamin-multimineral products. Considering the widespread adoption of supplements, it is essential to integrate these consumption data with food-derived nutrient intakes to accurately assess total nutrient exposure.
