Background: This study was motivated by the importance of iron tablet consumption to prevent anemia in adolescent girls. Adolescence is a critical developmental phase, and iron deficiency can negatively impact physical and mental health. The study was conducted at Public Junior High School 1 Semarapura to identify the consumption behavior of iron tablets, focusing on the timing, dosage, and consumption technique. Methods: This study employed a quantitative approach with a descriptive design. The sample was 260 respondents who were randomly drawn. Data were collected through a questionnaire containing questions related to the time, dose, and technique of iron tablet consumption. The collected data were then analyzed using univariate analysis to describe the characteristics and frequency of distribution. Results: The results showed that in terms of the consumption time, the majority of respondents (43.1%) were categorized as “enough;” 56.9% were categorized “enough” in terms of consumption dose; and 59.3% were categorized “insufficient” in terms of the consumption technique. In general, it was necessary to improve the iron tablet consumption behavior to reach the optimal level. Conclusion: The main obstructions in iron tablet consumption were lack of education, side effects of tablets such as nausea, and lack of motivation from the respondents. Factors such as support from parents, teachers, and health workers are considered very important to improve the consumption behavior. This study also suggests increased community-based education and interventions involving schools and families. Keywords: Consumption behavior, iron tablets, adolescent girls, anemia
