This study explored nutritional supplement attributes and consumption trends among youngsters facing dietary and health challenges. Surveying 2,100 parents of preschoolers, logistic regression models identified factors predicting supplement consumption, differentiating between vitamins/minerals and those with additional substances. The study investigated perspectives of parents not administering supplements. Approximately 15% of children reported supplement use, influenced by parental characteristics and a preference for natural products. Safety outweighed efficacy, with limited awareness of public authorities' food systems. Parents knowledgeable about child-specific vitamins made informed choices. These findings illuminate factors influencing parental decisions on nutritional supplements for preschoolers, emphasizing the need for targeted educational efforts to enhance awareness and informed decision-making.
