    Objective: To systematically analyze the available evidence from studies on the effectiveness of vitamin A and iron supplementation in the prevention of anemia in children under 5 years of age. Materials and Methods: The systematic review of 10 scientific articles found on the effectiveness of vitamin A and iron supplementation in the prevention of anemia in children under 5 years of age was conducted using the following databases: Cochrane, Lilacs, Scielo, Medline, PubMed. All articles were analyzed according to the grading scale to determine their strength and quality of evidence. Results: 90% (9/10) demonstrate the effectiveness of vitamin A and iron supplementation in preventing anemia in children under 5 years of age, while 10% of the reviewed articles conclude that more studies are needed to demonstrate the effectiveness of vitamin A and iron supplements in preventing anemia in children under 5 years of age. Conclusions: Of the 10 articles systematically reviewed, 9 articles show the effectiveness of vitamin A and iron supplementation in preventing anemia in children under 5 years of age, while 2 articles conclude that larger population studies are needed to demonstrate the effectiveness of vitamin A and iron supplementation in preventing anemia.
