This study aimed to identify the sociodemographic and health-related factors associated with the consumption of voluntarily fortified foods with micronutrients (Mn-FF) by the Portuguese population, using data from the National Food, Nutrition and Physical Activity Survey (IAN-AF 2015–2016). Food consumption, sociodemographic and other health-related factors, and physical activity data were computerised using the You Eat & Move e-platform. Foods consumed by participants and labelled foods reported as consumed were included in the database. Mn-FF were considered all foods containing added micronutrients legally authorised, and MN-FF users were those who consumed at least one Mn-FF on at least one of the dietary recall days. Approximately 57% of the population consumed at least one Mn-FF. Children and adolescents consumed significantly more Mn-FF than older age groups. The primary contributors to Mn-FF consumption were breakfast cereals and fat spreads. Being a child (female OR 2.07 [95% CI: 1.52, 2.83]; male OR 4.80 [95% CI: 3.23, 7.14]) or adolescent (female OR 1.62 [95% CI: 1.78, 2.22]; male OR 4.59 [95% CI: 3.26, 6.47]), having a higher level of education (female OR 1.52 [95% CI: 1.17, 1.99]; male OR 1.85 [95% CI: 1.42, 2.42]) and engaging in regular physical activity (female OR 1.31 [95% CI: 1.09, 1.58]; male OR 1.36 [95% CI: 1.11, 1.68]) were factors positively associated with Mn-FF consumption. Conversely, obesity (female OR 0.76 [95% CI: 0.60, 0.96]), living in predominantly rural areas (male OR 0.70 [95% CI: 0.49, 0.91]) and eating fewer mid-meals per day (female OR 0.60 [95% CI: 0.48, 0.76]; male OR 0.64 [95% CI: 0.49, 0.84]) were associated with lower Mn-FF consumption. Younger age, higher education and physical activity practice were positively associated with Mn-FF consumption. These findings provide important insights on priority factors to be considered when deciding on nutrient fortification policies from both public health and food industry perspectives.
