                                According to the National Institutes of Health, the Recommended Dietary Allowance (RDA) for iron in adult women (19–50) is 18 mg per day, significantly higher than the 8 mg recommended for adult men. This raises important questions about using children's vitamins like Flintstones with iron, which are not formulated for adult nutritional needs.
