Introduction. Dietary supplements have become a common practice, including among children. It is worth noting that supplementation can have a twofold effect: a pro-health effect – improving the nutritional status of the body, or a harmful effect – increasing the risk of nutrient overdose, such as when several preparations are used simultaneously. Objective. The aim of the study was to assess the determinants of dietary supplement consumption by children aged 3-10. Material and Methods. The study used a questionnaire method among parents of 151 children attending kindergarten and elementary schools in the Mazovia Province. Results. Dietary supplements were used by 54.3% of the children surveyed the year before the study. Women with a university education were significantly more likely to supplement their children than women with a secondary or primary education (60.6% and 42.3%, respectively). More children with normal body weight (58.6%) were given supplements than those with overweight and obesity (27.3%). The vast majority of children (66%) took one supplement daily. Concomitant use of supplements with fortified products was observed in 71.4% of respondents. The decision to use a supplement was mainly made by the parents themselves (62%). Conclusions. Educating parents about the benefits and risks of using dietary supplements is necessary. The use of such preparations should be consulted with a specialist, i.e., a doctor or dietician. It is worth noting that a well-balanced diet should provide all the nutrients, vitamins, and minerals for the child’s proper development.
